Engineering Selection Recommendations
Active Product Status Substitutes:
The TLC1078CDR (Texas Instruments) is the primary recommended substitute for the TS272ACDT. Both devices are CMOS amplifiers with dual circuits in 8-SOIC packages, RoHS3 compliant, and MSL Level 1. The TLC1078CDR maintains active product status, ensuring long-term availability and supply chain stability. The device operates within the same supply voltage range (1.4V to 16V) and temperature range (0°C to 70°C) as the TS272ACDT.
The TLC1078ID (Texas Instruments) is an alternative active substitute with extended operating temperature range (-40°C to 85°C) and identical electrical specifications to the TLC1078CDR. This variant is suitable for applications requiring broader temperature performance.
Last Time Buy Substitutes:
The TLC252ACD and TLC252CD (Texas Instruments) are CMOS dual-channel amplifiers with comparable slew rate (2.9 V/µs) and gain bandwidth product (2.2 MHz). Both devices are designated Last Time Buy, indicating limited future availability. These parts are suitable for applications where the TS272ACDT's higher bandwidth is not required.
The TLC25L2 series (TLC25L2ACD, TLC25L2CD, TLC25L2CDR) comprises CMOS amplifiers with single-ended output configuration and significantly lower supply current (29 µA per channel). These devices are designated Last Time Buy and are appropriate for low-power applications where the TS272ACDT's higher output current capability is unnecessary.
The TLC25M2ACD (Texas Instruments) features open-drain output configuration and is designated Last Time Buy. This variant is suitable for applications requiring open-drain output topology.
Obsolete Status:
The LM432MA/NOPB (Texas Instruments) is classified as obsolete and should not be selected for new designs. This general-purpose amplifier does not meet the CMOS amplifier type specification of the TS272ACDT.
Compliance and Certification:
All recommended substitutes maintain RoHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, matching the TS272ACDT's environmental certifications. All parts are classified under ECCN EAR99 and HTSUS 8542.33.0001.
Frequently Asked Questions (FAQ)
Q: Can the TLC1078CDR directly replace the TS272ACDT in all applications?
A: The TLC1078CDR is electrically compatible with the TS272ACDT in terms of package, pin configuration, and supply voltage range. However, the TLC1078CDR has significantly lower slew rate (0.032 V/µs versus 5.5 V/µs) and gain bandwidth product (110 kHz versus 3.5 MHz). Direct substitution is appropriate only for applications where these lower performance specifications are acceptable.
Q: What is the primary difference between TLC252ACD and TLC252CD?
A: Both devices are CMOS dual-channel amplifiers with identical electrical performance. The primary difference is input bias current specification: TLC252ACD specifies 1 pA, while TLC252CD specifies 0.6 pA. Both are designated Last Time Buy.
Q: Why are some substitute parts designated Last Time Buy?
A: Last Time Buy designation indicates that the manufacturer has announced end-of-life for the product. These parts remain available in current inventory but will not be manufactured beyond a specified date. For new designs requiring long-term component availability, active status products such as TLC1078CDR or TLC1078ID are preferred.
Q: Are all substitute parts available in the same packaging options as the TS272ACDT?
A: The TS272ACDT is available in Cut Tape (CT) and Digi-Reel packaging. Substitute parts are available in various packaging configurations including Tube and Tape & Reel (TR). Packaging selection should be confirmed based on assembly requirements and supplier availability.
Q: What is the significance of the 8-SOIC package specification?
A: The 8-SOIC (Small Outline Integrated Circuit) package is a surface mount package with 0.154-inch (3.90mm) width. All listed substitute parts use this identical package, ensuring mechanical and electrical compatibility with the TS272ACDT in PCB layouts and assembly processes.
Q: Can the TS272ACDT be used in applications requiring extended temperature range (-40°C to 85°C)?
A: The TS272ACDT operates within 0°C to 70°C temperature range. For applications requiring extended temperature performance, the TLC1078ID (operating -40°C to 85°C) is the appropriate substitute.
Q: What is the difference between single-ended and open-drain output configurations?
A: The TS272ACDT has standard output configuration. The TLC25L2 series features single-ended output, while the TLC25M2ACD features open-drain output. These output types affect circuit design and biasing requirements. Substitution with different output types requires circuit redesign.
Q: How does supply current affect component selection?
A: The TS272ACDT draws 1 mA per channel. Lower supply current alternatives such as TLC25L2 series (29 µA per channel) reduce power consumption but may not be suitable for applications requiring the TS272ACDT's output current capability (45 mA per channel). Selection depends on specific application power budget and output drive requirements.
