SN74ALVCH374DWR

Flip Flops Overview

The SN74ALVCH374DWR is an octal positive-edge-triggered D-type flip-flop with 3-state outputs manufactured by Texas Instruments. It operates from a supply voltage range of 1.65 V to 3.6 V and features a maximum propagation delay of 3.6 ns at 3.3 V. The device provides ±24-mA output drive capability and includes bus hold functionality on data inputs to eliminate the need for external pull-up or pull-down resistors. It is housed in a 20-SOIC package.

Flip Flops Procurement Notes

Verify the complete part number including the 'DWR' suffix to ensure correct SOIC-20 packaging and reel quantity specifications. Confirm RoHS compliance status and lead-free soldering characteristics against current manufacturer documentation. Check for any specific handling sensitivity notes regarding the low-voltage CMOS technology used in this component series.

Flip Flops Selection Notes

Select this component when designing systems requiring high-speed data storage with low voltage operation between 1.65 V and 3.6 V. The 3.6 ns propagation delay supports high-frequency digital logic applications. Consider the ±24 mA drive strength for direct interfacing with loads without additional buffering. The bus hold feature simplifies PCB layout by removing the need for passive components on input lines.

Flip Flops Part Context

This device belongs to the SN74ALVCH family of advanced low-voltage CMOS logic ICs. It complements other octal flip-flops like the SN74LVTH374 but offers faster switching speeds and lower voltage operation. The SOIC-20 package is standard for surface-mount assembly in compact electronic designs requiring multiple parallel data paths.
