74AHC74PW/S400J

Overview

The Nexperia 74AHC74PW/S400J is a dual D-type flip-flop with set and reset inputs, housed in a TSSOP-14 package. It operates within a supply voltage range of 2.0 V to 5.5 V. The device features overvoltage tolerant inputs up to 5.5 V, ensuring compatibility in mixed-voltage environments. It includes Schmitt-trigger actions on all inputs for high noise immunity and offers ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). The component is specified for operation from -40 °C to +125 °C.

Feature Summary

• Dual D-type flip-flops with independent set and reset functions
• Overvoltage tolerant inputs compatible with 5.5 V systems
• Schmitt-trigger inputs provide enhanced noise immunity
• High electrostatic discharge protection capabilities

Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• Timing delay applications
• Level translation between different logic families

Procurement Notes

Verify the specific suffix 'S400J' against official Nexperia documentation to confirm package variant and reel specifications. Ensure the ordering part number matches the required tape and reel configuration. Confirm AEC-Q100 qualification status if automotive compliance is mandatory for the target application environment.

Selection Notes

Select this component when dual edge-triggered storage with asynchronous control is required in low-power CMOS designs. The wide supply voltage range supports both 3.3 V and 5 V logic systems. Consider the TSSOP-14 package for space-constrained surface-mount assemblies requiring high pin density.

Part Context

This device belongs to the Nexperia 74AHC series, which utilizes advanced CMOS technology for high-speed operation with low power consumption. The AHC family is designed to replace older HC/HCT logic families while offering improved performance characteristics and broader operating voltage ranges suitable for modern embedded systems.

Replacement Considerations

Check for direct equivalents such as the 74AHC74PW,118 or other manufacturers' 74AHC74 variants. Verify pinout compatibility and electrical parameters before substitution. Ensure the replacement part meets the same temperature and voltage requirements.
