SN74AUC16373DGVR

Overview

The SN74AUC16373DGVR is a 16-bit transparent D-type latch with 3-state outputs from the Texas Instruments Widebus family. It operates at supply voltages from 0.8 V to 2.7 V, optimized for 1.8-V operation and featuring 3.6-V I/O tolerance. The device supports sub-1-V operation with a maximum propagation delay of 2 ns at 1.8 V. It includes Ioff circuitry for partial-power-down mode and offers ±8-mA output drive at 1.8 V. Packaged in a 48-pin TVSOP (DGV) with tape-and-reel shipping.

Feature Summary

• Supports mixed-mode signal operation through 3.6-V I/O tolerance while operating at lower supply voltages
• Enables partial-power-down applications via integrated Ioff circuitry that prevents damaging current backflow
• Provides high-speed data transfer with a maximum propagation delay of 2 ns at 1.8 V
• Configurable as two 8-bit latches or one 16-bit latch with buffered output-enable inputs

Applications

• Buffer registers
• I/O ports
• Bidirectional bus drivers
• Working registers

Procurement Notes

Verify the ordering suffix 'DGVR' corresponds to the TVSOP-48 package and tape-and-reel quantity. Confirm RoHS compliance and lead finish specifications match project requirements. Ensure ESD protection ratings meet system safety standards. Check moisture sensitivity level and reflow temperature profiles against assembly capabilities.

Selection Notes

Select this component for low-voltage digital systems requiring high-density latching. The 3.6-V tolerant inputs allow interfacing with higher voltage logic without level shifters. Consider the 48-pin TVSOP package constraints for PCB layout. Evaluate power consumption needs against the 20-uA max ICC specification.

Part Context

This part belongs to the SN74AUC16373 series within the Texas Instruments Widebus family. It is designed specifically for 1.65-V to 1.95-V VCC operation but functions across a broader 0.8-V to 2.7-V range. The DGVR suffix indicates the specific TVSOP package variant available in tape-and-reel format for automated assembly.

Replacement Considerations

SN74AUC16373DGGR is a direct pin-compatible substitute in a TSSOP package.
