SN74ALVCH16721DGVR

Flip Flops Overview

The SN74ALVCH16721DGVR is a single-element, 20-bit D-type flip-flop manufactured by Texas Instruments. It operates within a supply voltage range of 1.65V to 3.6V and features three-state outputs with high drive capability of 24mA for both high and low states. The device is housed in a 56-TFSOP package (0.173 inch width) and supports surface mount installation. It functions reliably across an operating temperature range of -40°C to 85°C.

Flip Flops Feature Summary

• Provides 20-bit data storage capability in a single integrated circuit element
• Features three-state outputs for effective bus driving and isolation
• Supports low-voltage operation from 1.65V to 3.6V for power efficiency

Flip Flops Applications

• High-density memory buffer systems
• Parallel-to-serial data conversion interfaces
• General-purpose register applications in embedded controllers

Flip Flops Procurement Notes

Verify the specific suffix DGVR corresponds to the Tape & Reel packaging format required for automated assembly processes. Confirm that the 56-TFSOP footprint matches the target PCB design constraints. Ensure the 1.65V to 3.6V supply rail compatibility aligns with the system's power distribution network before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when a high-pin-count, single-package solution for 20-bit storage is required. It is suitable for designs needing low-voltage compatibility and strong output drive capabilities. Consider the 56-TFSOP package dimensions against available board space. This part is appropriate for applications requiring synchronous data latching with tri-state control.

Flip Flops Part Context

This device belongs to the Texas Instruments SN74ALVCH series, which is designed for low-voltage CMOS logic applications. The ALVCH family offers performance improvements over standard LVCMOS devices while maintaining compatibility with 3.3V and lower voltage systems. The SN74ALVCH16721 variant specifically addresses the need for wide-data-path storage in compact form factors.

Flip Flops Replacement Considerations

Check for equivalent parts within the same ALVCH family or compatible 3.3V logic families. Verify pinout compatibility and electrical specifications such as output current and propagation delay. Ensure the replacement package matches the 56-TFSOP physical dimensions if board rework is not planned.
