74AHCT74PW-Q100J

Overview

The Nexperia 74AHCT74PW-Q100J is an automotive-grade dual D-type flip-flop with positive-edge triggering, part of the 74AHCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible inputs for seamless integration with legacy systems. The device provides complementary outputs and includes dedicated Set and Reset pins for direct control. Designed for high-speed applications, it offers low propagation delay and robust noise immunity. The component is housed in a TSSOP-14 surface-mount package and complies with AEC-Q100 qualification standards.

Feature Summary

• Dual D-type flip-flops with positive-edge clock triggering
• TTL-compatible input thresholds for mixed-voltage system interfacing
• Independent asynchronous Set and Reset functionality
• Complementary output configuration

Applications

• Automotive data acquisition and signal conditioning circuits
• High-speed digital state storage in vehicle control units
• Parallel-to-serial data conversion interfaces
• Timing synchronization and pulse generation modules

Procurement Notes

Verify that the specific suffix 'Q100J' corresponds to the intended AEC-Q100 qualified variant rather than standard commercial grades. Confirm package dimensions match the TSSOP-14 footprint requirements. Ensure the ordering code aligns with the manufacturer's current production status, as automotive components may have extended lead times or specific manufacturing site designations that impact availability.

Selection Notes

Select this component when TTL-level input compatibility is required alongside AHCT speed performance in automotive environments. It serves as a suitable replacement for older 74HCT74 devices where higher switching speeds are necessary. Consider the operating temperature range and power dissipation limits relative to the PCB layout. Verify that the asynchronous Set and Reset signals meet the timing requirements of the target application.
