SN74HC174PW

Flip Flops Overview

The SN74HC174PWR is a hex D-type flip-flop from Texas Instruments' HC logic family, housed in a 16-TSSOP package. It features positive-edge triggering and non-inverting outputs with a master reset function. Operating on a 2V to 6V supply, it delivers up to 5.2mA output current. Key electrical parameters include a maximum clock frequency of 50 MHz, propagation delay of 27ns at 6V/50pF, and static current of 8µA. The device supports surface mount installation across a -40°C to 85°C temperature range.

Flip Flops Feature Summary

• Integrates six independent D-type flip-flops within a single integrated circuit for compact digital storage applications.
• Utilizes positive-edge triggered clocking mechanism to synchronize data input transitions accurately.
• Incorporates a dedicated master reset input line to simultaneously clear all internal flip-flop states.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations for data expansion
• General-purpose digital memory storage elements

Flip Flops Procurement Notes

Verify the specific ordering suffix against official Texas Instruments documentation to confirm package type and reel specifications. Ensure compatibility with standard TSSOP-16 footprint requirements during PCB layout. Confirm RoHS compliance status matches project environmental regulations before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when requiring high-density hex flip-flops in a small surface-mount form factor. Consider the 50 MHz speed limit and 2V-6V operating range against system voltage rails. Evaluate the 27ns propagation delay for timing constraints in synchronous digital designs compared to faster AHC or HCS alternatives.

Flip Flops Part Context

This part belongs to the widely adopted 74HC series of CMOS logic devices, known for broad industry compatibility. It serves as a fundamental building block for sequential logic circuits. The TSSOP packaging facilitates automated assembly processes in modern electronics manufacturing environments.

Flip Flops Replacement Considerations

SN74HC174DR offers identical functionality in a SOIC-16 package. SN74HCS174PWR provides enhanced Schmitt-trigger inputs and higher speed in the same TSSOP-16 housing. Verify pinout compatibility and thermal characteristics when substituting.
