SN74AUC16373DGGR

Overview

The SN74AUC16373DGGR is a 16-bit transparent D-type latch with 3-state outputs from the Texas Instruments Widebus family. It operates at supply voltages ranging from 0.8 V to 2.7 V, optimized for 1.65 V to 1.95 V operation. The device features a maximum propagation delay of 2 ns at 1.8 V and supports partial-power-down mode via Ioff circuitry. It provides ±8-mA output drive at 1.8 V and includes ESD protection exceeding 2000-V human-body model standards. Packaged in a 48-pin TSSOP (DGG) with tape and reel shipping.

Feature Summary

• Configurable as two 8-bit latches or one 16-bit latch
• Supports mixed-mode signal operation with 3.6-V I/O tolerance
• Enables high-impedance state without interface components

Applications

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

Procurement Notes

Verify the specific package variant against design requirements, as the DGGR suffix denotes the 48-pin TSSOP form factor. Confirm that the operating voltage range aligns with the target system's power rails. Ensure proper handling procedures are followed due to the surface-mount nature of the component.

Selection Notes

Select this component when low-voltage operation below 1.8 V is required alongside high-speed data retention capabilities. The wide input voltage tolerance allows compatibility with higher voltage logic interfaces without additional level shifting. Consider the thermal impedance characteristics if multiple devices are mounted closely on the PCB.

Part Context

This part belongs to the SN74AUC series, designed for sub-1-V operability and low power consumption. It serves as a digital storage element within complex logic circuits, providing data buffering and temporary storage functions essential for synchronous digital systems.
