SN74AHC08PWR

Overview

The SN74AHC08PWR is a quad 2-input positive AND gate manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 5.5V and features low static power consumption with a maximum quiescent current of 2 µA. The device provides symmetrical output drive currents of 8mA for both high and low states. Propagation delay is specified at 7.9ns when operating at 5V with a 50pF load. It is housed in a 14-TSSOP surface-mount package and supports an extended operating temperature range from -40°C to 125°C.

Feature Summary

• CMOS technology ensures low power dissipation while maintaining high noise immunity across the full voltage range.
• Symmetrical output drive capability allows for efficient interfacing with various logic families without external buffering.
• Wide operating voltage range supports compatibility with systems utilizing 3.3V or 5V power rails.

Applications

• High-speed data bus switching applications
• Clock signal gating and timing control circuits
• Memory address decoding logic

Procurement Notes

Verify the specific ordering suffix to confirm the package type and tape-and-reel specifications. Ensure the component meets RoHS3 compliance requirements for your assembly process. Confirm that the moisture sensitivity level (MSL 1) aligns with your facility's floor life management protocols before soldering.

Selection Notes

Select this component when a quad AND gate configuration is required for 3.3V or 5V logic systems. It serves as a direct replacement for older HC series gates where lower power consumption and higher speed are necessary. Consider the TSSOP-14 footprint constraints during PCB layout to ensure adequate thermal relief and trace routing.

Part Context

This part belongs to the SN74AHC08 family, which utilizes advanced CMOS technology to deliver high-speed performance comparable to LS/TTL logic but with significantly reduced power usage. The 'PWR' suffix specifically denotes the 14-pin Thin-Shrink Small Outline Package (TSSOP), designed for space-constrained surface-mount applications.

Replacement Considerations

SN74AHC08DR: Same logical function and electrical characteristics packaged in 14-SOIC instead of TSSOP. SN74AHC08DBR: Identical functionality housed in a 14-SSOP package. Verify pinout compatibility and physical dimensions before substituting.
