SN74AHCT08PWRG4

Overview

The SN74AHCT08PWRG4 is a quadruple 2-input positive-AND gate manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible inputs allowing up translation from 3.3 V to 5 V. The device provides balanced output drive with low current capabilities, specifically ±8 mA for both high and low states. Propagation delay is specified at a maximum of 9 ns under a 50 pF load condition. It is housed in a 14-pin TSSOP package and supports an operating temperature range from -40°C to 125°C.

Feature Summary

• TTL-voltage compatible inputs enable direct interfacing with legacy logic systems.
• Low-drive CMOS architecture minimizes signal overshoot and undershoot on outputs.
• Slow rise and fall times reduce ringing effects on output signals.

Applications

• Servers
• Network switches
• PCs and notebooks
• Electronic points-of-sale

Procurement Notes

Verify the component authenticity against official Texas Instruments documentation. Confirm that the G4 suffix indicates compliance with RoHS standards and lead-free manufacturing specifications. Ensure the TSSOP package dimensions match your PCB footprint requirements. Validate the moisture sensitivity level rating before soldering processes to prevent damage during assembly.

Selection Notes

Select this component when TTL input compatibility is required alongside 5 V CMOS operation. The slow edge rates make it suitable for applications where minimizing electromagnetic interference and signal ringing is critical. Verify that the ±8 mA output drive capability meets the load requirements of the connected circuitry without exceeding absolute maximum ratings.

Part Context

This part belongs to the SNx4AHCT08 family of quadruple 2-input positive-AND gates. It utilizes advanced CMOS technology to provide balanced output drive characteristics. The device is designed to interface between different logic families, specifically bridging 3.3 V and 5 V domains through its specific input threshold voltages.

FAQ

How does the device handle unused inputs?

All unused inputs must be tied to either VCC or GND to prevent undefined operational states caused by floating pins.

What is the purpose of the slow rise and fall times?

The slow transition times are designed to minimize overshoot and undershoot, thereby reducing ringing on the output signals.
