SN74ALVCH162721DLR

Flip Flops Overview

The SN74ALVCH162721DLR is a 3.3-V 20-bit D-type flip-flop with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 3.0 V to 3.6 V and supports data rates up to 150 MHz. The device features positive-edge triggering and non-inverting outputs. It is housed in a 56-pin SSOP package (0.295 inch width) suitable for surface-mount applications. The component ensures high-speed data storage and transfer capabilities for digital systems requiring wide bus interfaces.

Flip Flops Feature Summary

• Provides 20-bit D-type flip-flop functionality with positive-edge clock triggering
• Features 3-state outputs allowing direct connection to system buses
• Supports high-speed operation with data rates up to 150 MHz
• Designed for low-voltage 3.3-V CMOS logic applications

Flip Flops Applications

• High-speed data storage registers in communication systems
• Parallel-to-serial conversion circuits
• Bus interface buffering for microprocessor systems
• Memory address latching in embedded controllers

Flip Flops Procurement Notes

Verify the specific suffix 'DLR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 3.3-V operating voltage aligns with the target system's power rails. Ensure the 56-pin SSOP footprint matches the PCB layout specifications. Check for RoHS compliance status if environmental regulations apply to the final product assembly.

Flip Flops Selection Notes

Select this component when designing systems requiring wide parallel data latching at high frequencies. The 150 MHz speed rating makes it suitable for modern bus architectures. Consider the 3-state output capability for efficient bus sharing without additional tri-state buffers. Evaluate the thermal performance within the SSOP package for dense board layouts.

Flip Flops Part Context

This part belongs to the SN74ALVCH family of advanced low-voltage CMOS logic devices from Texas Instruments. The ALVCH series is optimized for 3.3-V applications, offering improved performance over standard 5-V logic families. It complements other buffer and driver components in the same voltage domain, providing comprehensive solutions for mixed-voltage system designs.

Flip Flops Replacement Considerations

Direct substitutes include the SN74ALVCH162721DGGR variant, which offers identical electrical characteristics but utilizes a TSSOP package instead of SSOP. Designers must verify pin compatibility and mechanical dimensions before swapping packages. Other family members like the SN74ALVCH162721DL may serve as alternatives depending on specific packaging requirements.
