74AHCT08D,112

Overview

The Nexperia 74AHCT08D,112 is a quad 2-input AND gate in the 74AHCT logic series. It operates within a supply voltage range of 4.5 V to 5.5 V and accepts TTL-level inputs. The device features Schmitt-trigger action on all inputs for noise immunity and overvoltage tolerance up to 5.5 V. It is housed in a SO14 (SOT108-1) plastic small outline package with a body width of 3.9 mm. Propagation delay is specified at 6.9 ns maximum under typical conditions.

Feature Summary

• Quad 2-input AND logic function
• TTL-compatible input levels
• Overvoltage tolerant inputs
• Schmitt-trigger action

Applications

• Mixed voltage translation environments
• Digital signal processing circuits
• Logic level interfacing

Procurement Notes

Verify the specific ordering suffix against current Nexperia documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and check for any recent Product Change Notifications regarding manufacturing site or material changes before finalizing procurement plans.

Selection Notes

Select this component when TTL-level compatibility is required alongside CMOS performance characteristics. Ensure the application environment stays within the recommended operating temperature range of -40 °C to +125 °C. Verify that the load capacitance requirements align with the dynamic performance specifications provided in the datasheet.

Part Context

This part belongs to the 74AHC/AHCT family of high-speed CMOS logic devices. The AHCT variant specifically bridges TTL and CMOS logic families by providing TTL-compatible input thresholds while maintaining CMOS output drive capabilities. The 'D' suffix indicates the SO14 surface-mount package configuration.

Replacement Considerations

Direct substitutes include other manufacturers' 74AHCT08 parts in SO14 packages. Verify pinout compatibility and electrical parameters such as propagation delay and output current drive strength before substitution.
