SN74AHCT08PWR-P

Overview

The SN74AHCT08PWR is a quadruple 2-input positive-AND gate from the Texas Instruments AHCT logic family. It operates on a single 4.5 V to 5.5 V supply and features TTL-compatible inputs allowing up-conversion from 3.3 V sources. The device provides balanced output drive with ±8 mA current capability. Propagation delay ranges from 1 ns to 9 ns depending on load capacitance (15 pF or 50 pF). It is housed in a 14-pin TSSOP package and supports an operating temperature range of -40°C to +125°C.

Feature Summary

• TTL-voltage compatible inputs enable direct interfacing with 3.3 V logic systems while translating signals to 5 V levels.
• Low-drive CMOS architecture produces slow rise and fall times, minimizing signal overshoot and undershoot.
• High electrostatic discharge protection ratings ensure robustness against human-body, machine model, and charged-device model events.

Applications

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

Procurement Notes

Verify the specific ordering suffix 'PWR' corresponds to the TSSOP-14 package configuration required for your PCB layout. Confirm that the lead finish and moisture sensitivity level meet your assembly process specifications. Ensure the component status is listed as active production rather than obsolete or not recommended for new designs.

Selection Notes

Select this component when system design requires low-noise outputs due to controlled edge rates. It is suitable for bus-interface applications where output ringing must be minimized. Verify that the 4.5 V minimum supply voltage aligns with the available power rails in the target application environment.

Part Context

This part belongs to the SNx4AHCT08 series of quadruple 2-input positive-AND gates. The AHCT designation indicates compatibility with standard TTL input voltage levels while utilizing advanced CMOS technology for performance. The PW suffix specifically denotes the Thin Shrink Small Outline Package (TSSOP) variant within the broader product family.

FAQ

How does the output drive affect signal integrity?

The device utilizes a low-drive CMOS architecture that intentionally creates slow rise and fall times. This characteristic reduces ringing on the output signal, making it ideal for applications sensitive to overshoot and undershoot.

Can this IC interface directly with 3.3 V logic?

Yes, the inputs are TTL-voltage compatible. They can accept voltages down to 3.3 V and translate them up to the 5 V logic levels required by the outputs.
