Primary Compatibility Criteria:

Dual-channel CMOS amplifier architecture (2 circuits)
8-SOIC surface mount package (0.154", 3.90mm width)
Supply voltage range: 3V to 16V minimum overlap
Output current capability: minimum 30 mA per channel
Operating temperature range compatibility or extension

Substitution Logic:

Substitute parts are grouped into three functional categories based on performance characteristics:

Direct CMOS Substitutes (TS272 Series) – STMicroelectronics TS272ACDT, TS272AIDT, TS272BIDT, TS272CDT, TS272IDT: These devices maintain CMOS amplifier topology with 2 circuits in 8-SOIC packaging. They operate within the 3V to 16V supply range and provide 45 mA output current per channel. The TS272 series exhibits higher slew rate (5.5V/µs vs. 0.62V/µs) and gain bandwidth product (3.5 MHz vs. 635 kHz), making them suitable for applications tolerating or requiring enhanced frequency response.
Low-Power CMOS Substitutes (TS27L2 Series) – STMicroelectronics TS27L2ACDT, TS27L2AIDT, TS27L2BIDT, TS27L2CD: These devices provide CMOS dual-channel amplification in 8-SOIC packaging with reduced supply current (10µA vs. 285µA). They operate within the 3V to 16V supply range and deliver 45 mA output current per channel. The TS27L2 series exhibits lower slew rate (0.04V/µs) and gain bandwidth product (100 kHz), suitable for low-power applications with reduced bandwidth requirements.
General-Purpose Substitute (LM432MA/NOPB) – Texas Instruments: This general-purpose amplifier provides 2 circuits in 8-SOIC packaging with extended supply range (2.5V to 16V) and 30 mA output current per channel. Product status is Obsolete; this part is listed for reference only and should not be selected for new designs.

Engineering Selection Recommendations

For Active Product Status with Standard Temperature Range (0°C to 70°C):

Select TS272ACDT or TS272CDT when higher bandwidth performance is required. Both devices maintain Active product status, ROHS3 compliance, and MSL 1 rating. TS272ACDT provides 900 µV input offset voltage with Cut Tape packaging; TS272CDT provides 1.1 mV input offset voltage. Both operate within the 3V to 16V supply range and deliver 45 mA output current per channel.

Select TS27L2ACDT or TS27L2CD for low-power applications. Both maintain Active product status and ROHS3 compliance. TS27L2ACDT is supplied in Tape & Reel format with 900 µV input offset voltage; TS27L2CD is supplied in Tube format with 1.1 mV input offset voltage. Supply current is reduced to 10 µA per dual-channel configuration.

For Extended Temperature Range (-40°C to 125°C):

Select TS272AIDT, TS272BIDT, or TS272IDT. All three maintain Active product status and ROHS3 compliance. TS272AIDT and TS272IDT provide 900 µV and 1.1 mV input offset voltage respectively; TS272BIDT provides 250 µV input offset voltage. All deliver 45 mA output current per channel.

Select TS27L2AIDT or TS27L2BIDT for low-power extended temperature operation. Both maintain Active product status and ROHS3 compliance. TS27L2AIDT provides 1.1 mV input offset voltage; TS27L2BIDT provides 250 µV input offset voltage. Supply current is 10 µA per dual-channel configuration.

Frequently Asked Questions (FAQ)

Q: Can TS272 series parts directly replace TLC27M7CDR in existing designs?

A: Yes, TS272 series parts (TS272ACDT, TS272AIDT, TS272BIDT, TS272CDT, TS272IDT) are mechanically and electrically compatible. All share the 8-SOIC package, dual-channel CMOS architecture, and 3V to 16V supply range. The primary difference is higher slew rate (5.5V/µs vs. 0.62V/µs) and gain bandwidth product (3.5 MHz vs. 635 kHz). Applications sensitive to these performance differences require circuit validation.

Q: What is the difference between TS272ACDT and TS272CDT?

A: Both are STMicroelectronics TS272 devices in 8-SOIC packaging with identical electrical performance (5.5V/µs slew rate, 3.5 MHz gain bandwidth product, 45 mA output current). The difference is input offset voltage: TS272ACDT specifies 900 µV; TS272CDT specifies 1.1 mV. Both operate 0°C to 70°C. Selection depends on offset voltage tolerance requirements.

Q: When should TS27L2 series parts be selected?

A: TS27L2 series parts (TS27L2ACDT, TS27L2AIDT, TS27L2BIDT, TS27L2CD) are selected for applications requiring ultra-low supply current (10 µA vs. 285 µA). These devices maintain 8-SOIC packaging, dual-channel CMOS architecture, and 3V to 16V supply range. The trade-off is significantly reduced slew rate (0.04V/µs) and gain bandwidth product (100 kHz). Applications must tolerate these reduced frequency response characteristics.

Q: What is the temperature range difference between TS272ACDT and TS272AIDT?

A: TS272ACDT operates 0°C to 70°C; TS272AIDT operates -40°C to 125°C. Both are STMicroelectronics TS272 devices with identical electrical specifications (5.5V/µs slew rate, 3.5 MHz gain bandwidth product, 900 µV input offset voltage, 45 mA output current). Selection depends on application temperature requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (TS272 series, TS27L2 series, and LM432MA/NOPB) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the TLC27M7CDR compliance profile.

Q: Why is LM432MA/NOPB listed if it is Obsolete?

A: LM432MA/NOPB is included for reference and historical compatibility documentation only. This part is classified as Obsolete and must not be selected for new designs, production applications, or long-term inventory planning. Active alternatives from the TS272 and TS27L2 series are available.

Q: Can TS272 and TS27L2 series parts be used interchangeably?

A: No. While both series maintain 8-SOIC packaging, dual-channel CMOS architecture, and 3V to 16V supply range, they have fundamentally different performance characteristics. TS272 series provides higher bandwidth (3.5 MHz vs. 100 kHz) and higher slew rate (5.5V/µs vs. 0.04V/µs) but higher supply current (1 mA vs. 10 µA). Selection depends on application bandwidth and power consumption requirements.

Q: What packaging formats are available for TS272 series substitutes?

A: TS272ACDT and TS272CDT are supplied in Cut Tape (CT) & Digi-Reel® format. TS272AIDT, TS272BIDT, and TS272IDT are supplied in Tape & Reel (TR) format. All use 8-SOIC surface mount packaging. Selection depends on assembly process requirements.

Q: What packaging formats are available for TS27L2 series substitutes?

A: TS27L2ACDT is supplied in Tape & Reel (TR) format. TS27L2AIDT is supplied in Cut Tape (CT) & Digi-Reel® format. TS27L2BIDT is supplied in Tape & Reel (TR) format. TS27L2CD is supplied in Tube format. All use 8-SOIC surface mount packaging. Selection depends on assembly process requirements.
