SN74AHC373DGVR

Overview

The SN74AHC373DGVR is an octal transparent D-type latch manufactured by Texas Instruments, belonging to the AHC logic series. It features eight independent D-type latches with three-state outputs in a 20-TVSOP package. The device operates within a supply voltage range of 2 V to 5.5 V and supports a propagation delay of 14.9 ns or 9.2 ns depending on conditions. It provides a low-level output current of 32 mA and a high-level output current of -8 mA. The component functions at temperatures between -40°C and +85°C with a static current of 4 uA.

Feature Summary

• Provides eight independent transparent D-type latches for data storage applications
• Features three-state outputs to facilitate bus-oriented memory mapping and driving
• Operates across a wide supply voltage range from 2 V to 5.5 V
• Delivers high noise immunity and low power consumption typical of AHC logic

Applications

• Bus-oriented memory mapping systems
• Registering and buffering digital signals
• Driving high-capacitance or low-impedance loads

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Texas Instruments before integration. Confirm that the 20-TVSOP package dimensions match the target PCB footprint requirements. Ensure the operating environment remains within the specified temperature range of -40°C to +85°C for reliable performance.

Selection Notes

Select this component when an octal latch with three-state capability is required for system buses. The AHC series offers faster switching speeds compared to standard HC logic while maintaining lower power consumption. Verify that the 2 V to 5.5 V supply range aligns with the system's voltage rails and that the TVSOP-20 package fits the available board space.

Part Context

This part belongs to the SN74AHC373 family of octal transparent D-type latches. It shares the same logical function as other variants but differs in packaging, speed grades, or voltage ranges. The DGVR suffix indicates the specific TVSOP-20 surface-mount package and reel-based tape-and-reel shipping format used by Texas Instruments.
