Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74HC08PW is determined by strict adherence to the following criteria:

Mandatory Compatibility Parameters:

• Logic Type: AND Gate (4 channel, 2 input)
• Package: 14-TSSOP surface mount form factor
• Voltage Supply Range: Minimum 2V, Maximum 6V
• Operating Temperature: Minimum -40°C, Maximum 85°C or higher
• RoHS3 Compliance
• Moisture Sensitivity Level: 1 (Unlimited)

Electrical Performance Parameters:

• Current Output High/Low: 5.2mA / 5.2mA
• Input Logic Levels: Low 0.5V ~ 1.8V, High 1.5V ~ 4.2V
• Propagation Delay: 17ns maximum @ 6V, 50pF load

All substitute parts listed maintain these core parameters within acceptable engineering tolerances. Variations in quiescent current, propagation delay, and extended temperature ranges represent performance enhancements rather than functional limitations.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: SN74HC08PWR (Texas Instruments) Direct manufacturer equivalent with active product status. Maintains identical electrical performance and temperature range as the original SN74HC08PW. Packaging format differs (Cut Tape & Digi-Reel vs. Tube) but component functionality is identical. Highest inventory availability at 10400 units.

Performance-Enhanced Substitute: MC74HC08ADTR2G (onsemi) Offers superior electrical characteristics with lower quiescent current (1 µA vs. 2 µA) and faster propagation delay (13ns vs. 17ns). Extended operating temperature range (-55°C ~ 125°C) provides additional design margin. Largest inventory stock at 30200 units. Fully compliant with RoHS3 and MSL requirements.

Extended Temperature Substitute: 74HC08PW,118 (Nexperia USA Inc.) Maintains original electrical specifications with extended upper operating temperature limit (125°C vs. 85°C). Propagation delay of 15ns falls between standard and enhanced performance. Tape & Reel packaging. Highest inventory availability at 42412 units.

Extended Temperature Substitute: 74HC08T14-13 (Diodes Incorporated) Supports extended operating temperature range (-40°C ~ 125°C). Higher quiescent current specification (20 µA) represents the only notable parameter variance. Suitable for applications requiring wider temperature operation. Active product status with 22600 units in stock.

Compatible Substitute: MM74HC08MTCX (onsemi) Maintains original SN74HC08PW specifications including temperature range and quiescent current. Slightly higher propagation delay (20ns) remains within acceptable logic timing margins. Tape & Reel packaging format.

All substitute parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), and identical 14-TSSOP package geometry, ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can SN74HC08PWR be used as a direct replacement for SN74HC08PW? A: Yes. SN74HC08PWR is the active production equivalent from Texas Instruments. Both parts share identical logic functionality, electrical performance, and operating temperature range. The only difference is packaging format (Cut Tape & Digi-Reel vs. Tube), which does not affect component performance or PCB assembly compatibility.

Q: What is the difference between the substitute parts in terms of performance? A: MC74HC08ADTR2G offers the fastest propagation delay (13ns) and lowest quiescent current (1 µA), making it suitable for power-sensitive or timing-critical applications. 74HC08PW,118 and 74HC08T14-13 provide extended temperature operation to 125°C. MM74HC08MTCX maintains original specifications with slightly higher propagation delay (20ns). All parts meet the core 2V ~ 6V supply voltage and 5.2mA output current requirements.

Q: Are all substitute parts in the same 14-TSSOP package? A: Yes. All substitute parts use the 14-TSSOP (0.173", 4.40mm Width) surface mount package. PCB footprints and assembly processes remain identical across all listed alternatives.

Q: Which substitute part has the best inventory availability? A: 74HC08PW,118 from Nexperia USA Inc. has the highest inventory at 42412 units, followed by MC74HC08ADTR2G at 30200 units and 74HC08T14-13 at 22600 units.

Q: Do all substitute parts meet RoHS3 compliance? A: Yes. All listed substitute parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the original SN74HC08PW specifications.

Q: Can I use MC74HC08ADTR2G in an application designed for -40°C ~ 85°C operation? A: Yes. MC74HC08ADTR2G supports -55°C ~ 125°C operation, which encompasses the original -40°C ~ 85°C range. The extended temperature capability provides additional design margin without functional compromise.

Q: What is the significance of the different packaging formats (Tube, Cut Tape, Tape & Reel)? A: Packaging format affects procurement and assembly logistics but not component performance. Tube packaging is for manual handling, Cut Tape & Digi-Reel for semi-automated assembly, and Tape & Reel for fully automated pick-and-place systems. Select based on your manufacturing process requirements.
