SN74ALVCH373DGVR

Overview

The SN74ALVCH373DGVR is an octal transparent D-type latch manufactured by Texas Instruments, belonging to the 74ALVCH logic series. It features tri-state outputs and operates within a supply voltage range of 1.65 V to 3.6 V. The device utilizes a 20-TVSOP package with surface-mount installation. Key electrical specifications include a propagation delay of 4 ns and 3.6 ns, static current of 20 uA, low-level output current of 32 mA, and high-level output current of -24 mA. It supports an operating temperature range from -40 C to +85 C.

Feature Summary

• Provides eight D-type transparent latching channels for data storage applications.
• Features tri-state outputs to facilitate bus-driven architectures.
• Operates across a wide low-voltage power supply spectrum suitable for portable systems.

Applications

• Bus-oriented memory mapping
• Working as registers
• Performing two-level memory buffering

Procurement Notes

Verify the specific suffix 'DGVR' corresponds to the TVSOP-20 package and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements against the target assembly process. Ensure the voltage domain matches the 1.65 V to 3.6 V operational range before integration into the circuit design.

Selection Notes

Select this component when designing systems requiring octal latching with tri-state capability in low-voltage environments. Compare propagation delays and output drive strengths against alternative ALVCH series parts if higher speed or different voltage levels are required. Consider the TVSOP-20 footprint constraints during PCB layout planning.

Part Context

This part belongs to the SN74ALVCH373 family of octal transparent latches. It shares functional similarities with other members like the SN74AHC373 but differs in supply voltage and performance characteristics. The DGVR designation indicates the specific tape-and-reel packaging format used for automated assembly processes.

Replacement Considerations

SN74ALVCH373DGVRE4 is a verified equivalent variant within the same product line.
