SN74ACT14PWRG4 Equivalent & Substitute Parts

Part Overview

The SN74ACT14PWRG4 is a 6-channel inverter IC with Schmitt trigger inputs manufactured by Texas Instruments in a 14-TSSOP surface mount package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The device operates within a 4.5V to 5.5V supply voltage range and is suitable for logic signal inversion applications requiring hysteresis input characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SN74ACT14PWRG4 is determined by strict equivalence across the following parameters:

• Logic type (Inverter with 6 channels, 1 input per channel)
• Schmitt trigger feature requirement
• Supply voltage range (4.5V ~ 5.5V)
• Output current capability (24mA minimum for both high and low states)
• Operating temperature range (-40°C ~ 85°C)
• Surface mount package format (14-TSSOP)
• RoHS3 compliance and REACH unaffected status

The substitute parts listed below meet all these core electrical and mechanical requirements. Variations in quiescent current and propagation delay remain within acceptable tolerances for this product category.

Parameter Comparison

Engineering Selection Recommendations

SN74ACT14PWR (Texas Instruments) is the direct active equivalent from the original manufacturer. This part maintains identical electrical specifications and is recommended for designs requiring continuity with the original SN74ACT14PWRG4 specification.

74ACT14MTCX (onsemi) and MC74ACT14DTR2G (onsemi) are manufacturer-recommended alternatives that meet all core substitution criteria. Both parts are in active production status with higher inventory availability. The MC74ACT14DTR2G exhibits slightly elevated quiescent current (4 µA versus 2 µA) and marginally improved propagation delay (10ns versus 11.5ns), both within acceptable operational tolerances for this logic family.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original part.

Frequently Asked Questions (FAQ)

Q: Can SN74ACT14PWR be used as a direct replacement for SN74ACT14PWRG4?

A: Yes. SN74ACT14PWR is electrically and mechanically identical to SN74ACT14PWRG4. The primary difference is product status: SN74ACT14PWRG4 is obsolete while SN74ACT14PWR is active. Both are Texas Instruments products with identical specifications.

Q: What is the difference between the Texas Instruments and onsemi substitute parts?

A: All parts share identical logic type, channel count, Schmitt trigger feature, supply voltage range, output current capability, operating temperature range, and package format. The onsemi parts (74ACT14MTCX and MC74ACT14DTR2G) differ only in quiescent current specification and propagation delay, both within acceptable tolerances for 74ACT logic family applications.

Q: Are all substitute parts in the same package?

A: Yes. All parts use the 14-TSSOP surface mount package with identical physical dimensions (0.173" width, 4.40mm).

Q: Do the substitute parts meet the same compliance requirements?

A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, matching the original SN74ACT14PWRG4 compliance status.

Q: Which substitute part should be selected for new designs?

A: SN74ACT14PWR is recommended for designs requiring exact specification continuity. For applications where inventory availability is a priority, 74ACT14MTCX and MC74ACT14DTR2G are functionally equivalent alternatives with higher stock levels.
