SN74AHCT32PWRG4

Overview

The SN74AHCT32PWRG4 is a Texas Instruments logic gate featuring four independent 2-input positive-OR functions. It utilizes advanced high-speed CMOS technology and accepts TTL-compatible inputs while operating on a single 5V supply. The device is housed in a 14-pin TSSOP package. Key electrical specifications include a propagation delay of 7.9 ns at 5V with 50pF load, output currents of ±8 mA, and a supply voltage range of 4.5V to 5.5V.

Feature Summary

• Contains four independent 2-input OR gates for complex logic implementation
• Accepts TTL voltage levels at inputs for direct interfacing with TTL sources
• Operates from a single 5V power supply rail

Applications

• Digital signal processing circuits requiring OR logic operations
• Interface modules between TTL and CMOS logic domains
• General-purpose logic control systems

Procurement Notes

Verify the complete part number including the G4 suffix to ensure compliance with RoHS standards and lead-free manufacturing requirements. Confirm the TSSOP-14 package type matches your PCB footprint design. Cross-reference the datasheet revision date to ensure alignment with current technical specifications before finalizing procurement orders.

Selection Notes

Select this component when TTL input compatibility is required within a 5V CMOS system. The AHCT series bridges the voltage threshold gap between older TTL devices and modern CMOS outputs. Ensure the 7.9 ns propagation delay meets the timing constraints of your specific application circuit design.

Part Context

This part belongs to the SN74AHCT family of high-speed CMOS logic devices. The 'A' denotes advanced technology for speed, 'H' indicates CMOS construction, and 'CT' specifies TTL-compatible thresholds. The PWRG4 designation identifies the specific TSSOP-14 surface-mount package variant manufactured by Texas Instruments.

Replacement Considerations

SN74AHCT32PWR is a compatible alternative without the green (lead-free) suffix. SN74AHCT32PWREP serves as the military-enhanced version. Verify pinout compatibility and electrical characteristics before substituting these variants in existing designs.
