CD74HC08PW AND Gate IC 4 Channel 14-TSSOP Equivalent & Substitute Parts

Part Overview

The CD74HC08PW is a 4-channel AND gate logic IC manufactured by Texas Instruments in 14-TSSOP surface mount packaging. This part is discontinued at DiGi Electronics but remains available through inventory channels. The CD74HC08PW operates across a 2V to 6V supply range with low quiescent current and is suitable for general-purpose logic applications requiring AND gate functionality. Finding equivalent and substitute parts is necessary due to the discontinued status and to identify alternative sources with active product availability.

Substitute Part Grouping Explanation

Substitution of the CD74HC08PW is determined by strict equivalence across the following critical parameters:

Logic Type: AND Gate with 4 channels and 2 inputs per channel
Voltage Supply Range: 2V ~ 6V minimum requirement
Package Type: 14-TSSOP surface mount only
Mounting Type: Surface mount configuration
RoHS and MSL Compliance: ROHS3 Compliant, MSL 1

Substitute parts must maintain identical logic functionality, pin configuration, and package dimensions. Variations in quiescent current, propagation delay, operating temperature range, and product status are permitted provided the part meets or exceeds the minimum electrical specifications of the original part.

Engineering Selection Recommendations

Primary Recommendation: CD74HC08PWR

CD74HC08PWR is the direct equivalent to CD74HC08PW from Texas Instruments with identical electrical specifications and active product status. This part maintains the same voltage supply range, quiescent current, and propagation delay characteristics. The only difference is packaging format (Cut Tape & Digi-Reel® versus Tube), which does not affect electrical performance. Inventory availability is significantly higher at 4193 pieces.

Secondary Recommendation: MC74HC08ADTR2G

MC74HC08ADTR2G from onsemi meets all functional requirements with superior performance characteristics. Quiescent current is reduced to 1 µA and propagation delay is improved to 13ns at 6V with 50pF load. Operating temperature range extends to -55°C ~ 125°C, matching the original part. Inventory availability is the highest among all substitutes at 30200 pieces. Product status is active.

Alternative for Automotive Applications: 74HC08PW-Q100,118

74HC08PW-Q100,118 from Nexperia USA Inc. is qualified to AEC-Q100 automotive standards with active product status. Electrical specifications match the original part exactly. Operating temperature range is -40°C ~ 125°C. This part is suitable for automotive-grade applications requiring formal qualification documentation.

Not Recommended: 74HC08T14-13 and MM74HC08MTC/MM74HC08MTCX

74HC08T14-13 exhibits elevated quiescent current at 20 µA, which exceeds the original specification by a factor of 10. MM74HC08MTC and MM74HC08MTCX have reduced operating temperature range (-40°C ~ 85°C) and increased propagation delay (20ns), limiting suitability for wide-temperature applications.

Not Recommended: NLV74HC08ADTR2G

NLV74HC08ADTR2G has obsolete product status and should not be selected for new designs despite active inventory.

Frequently Asked Questions (FAQ)

Q: Can I use CD74HC08PWR as a direct replacement for CD74HC08PW?

A: Yes. CD74HC08PWR is electrically identical to CD74HC08PW with the same voltage supply range, quiescent current, and propagation delay. The packaging format differs (Cut Tape & Digi-Reel® versus Tube), but this does not affect circuit performance. Both parts are 14-TSSOP surface mount packages with identical pin configurations.

Q: What is the difference between the various onsemi part numbers (MC74HC08ADTR2G, MM74HC08MTC, MM74HC08MTCX)?

A: MC74HC08ADTR2G offers superior performance with 1 µA quiescent current and 13ns propagation delay. MM74HC08MTC and MM74HC08MTCX have identical specifications to each other but differ in packaging (Tube versus Tape & Reel). Both have higher quiescent current (2 µA) and propagation delay (20ns) compared to MC74HC08ADTR2G, and operate only to 85°C maximum.

Q: Is the 74HC08PW-Q100,118 suitable for my application?

A: 74HC08PW-Q100,118 is suitable if your application requires AEC-Q100 automotive qualification. Electrical specifications are identical to the original CD74HC08PW. Operating temperature range is -40°C ~ 125°C, which is narrower at the low end but sufficient for most automotive environments.

Q: Why does 74HC08T14-13 have higher quiescent current?

A: 74HC08T14-13 from Diodes Incorporated specifies 20 µA maximum quiescent current, which is 10 times higher than the original part. This difference is inherent to the Diodes Incorporated manufacturing process and must be considered in power budget calculations for battery-powered or low-power applications.

Q: Can I use NLV74HC08ADTR2G?

A: NLV74HC08ADTR2G is obsolete and should not be used for new designs. Although inventory is available, obsolete parts carry risk of supply discontinuation and lack of manufacturer support.

Q: What packaging options are available?

A: Substitute parts are available in three packaging formats: Tube (MM74HC08MTC), Cut Tape & Digi-Reel® (CD74HC08PWR, MC74HC08ADTR2G), and Tape & Reel (74HC08PW-Q100,118, 74HC08T14-13, MM74HC08MTCX). All maintain the same 14-TSSOP case dimensions and pin configuration. Selection depends on procurement and assembly requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original CD74HC08PW specifications.
