SN74HCS74PWR

Flip Flops Overview

The SN74HCS74PWR is a dual D-type flip-flop from Texas Instruments' HCS logic family, housed in a TSSOP-14 surface-mount package. It operates on a supply voltage range of 2 V to 6 V and supports a maximum clock frequency of 105 MHz. The device features Schmitt-trigger inputs for noise immunity and provides push-pull outputs with a typical propagation delay of 7 ns. Designed for automotive applications, it meets AEC-Q100 qualification standards and functions reliably within an operating temperature range of -40°C to +125°C.

Flip Flops Feature Summary

• Dual D-type edge-triggered flip-flops with integrated clear and preset controls
• Schmitt-trigger inputs provide enhanced noise filtering and signal integrity
• Automotive-grade reliability compliant with AEC-Q100 qualification standards
• Wide operating voltage range supporting low-power system designs

Flip Flops Applications

• Automotive electronic control units requiring robust data storage
• Industrial systems needing high noise immunity in harsh environments
• Digital state retention circuits in wide-temperature operational contexts

Flip Flops Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-14 package variant when sourcing. Confirm that the component meets AEC-Q100 requirements if deployed in automotive safety-critical systems. Ensure input signals respect the specified voltage limits to prevent latch-up or damage during operation.

Flip Flops Selection Notes

Select this component when designing circuits requiring dual independent flip-flops with Schmitt-trigger inputs for improved noise tolerance. It is suitable for applications demanding automotive qualification and wide temperature stability. Consider the TSSOP-14 footprint constraints and verify compatibility with existing PCB layout tools before integration.

Flip Flops Part Context

This part belongs to the SN74HCS series, which utilizes CMOS technology optimized for automotive and industrial markets. Unlike standard HC logic, the HCS family incorporates Schmitt triggers at all inputs to mitigate signal ringing and noise susceptibility. This design ensures stable switching characteristics even with slow-rise-time signals common in complex digital environments.

Flip Flops Replacement Considerations

SN74HCS74DRQ1: Automotive-grade alternative in SOIC-14 package. SN74HC74PWR: Standard commercial grade without Schmitt triggers or automotive qualification.
