SN74LVC16373AZQLR

Latches Overview

The SN74LVC16373AZQLR is a 16-bit transparent D-type latch with 3-state outputs from the Texas Instruments Widebus family. It operates from 1.65 V to 3.6 V and accepts input voltages up to 5.5 V, supporting mixed-mode signal operation. The device features a maximum propagation delay of 4.2 ns at 3.3 V and typical output ground bounce of 2 V. It includes Ioff support for live-insertion and back-drive protection, with latch-up performance exceeding 100 mA per JESD 78 Class II standards.

Latches Feature Summary

• Operates within a wide voltage range of 1.65 V to 3.6 V
• Inputs accept voltages up to 5.5 V for mixed-mode compatibility
• Ioff circuitry prevents damaging current backflow during power-down
• Supports live-insertion and partial-power-down applications

Latches Applications

• Servers
• Network switches
• Telecom infrastructures

Latches Procurement Notes

Verify the specific package type associated with the ZQL suffix against the manufacturer's official orderable addendum. Confirm that the selected variant meets the required thermal and moisture sensitivity levels for the intended manufacturing process. Ensure all unused inputs are properly biased to prevent undefined operational states.

Latches Selection Notes

Select this component for high-speed bus-interface applications requiring data retention or latching capabilities. The device provides balanced output drive suitable for driving multiple outputs. Consider the 5.5 V tolerant inputs when interfacing with 5-V devices in a 3.3-V system environment to facilitate voltage translation without additional components.

Latches Part Context

This part belongs to the SN74LVC16373A series, designed as a 16-bit transparent D-type latch. It functions as two 8-bit latches or one 16-bit latch. The device is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers in digital logic systems.

Latches FAQ

How does the Ioff feature benefit the SN74LVC16373AZQLR?

The Ioff feature disables the outputs when VCC is 0 V, preventing damaging current backflow through the device. This supports live-insertion and partial-power-down modes.

Can the SN74LVC16373AZQLR interface with 5-V logic?

Yes, the inputs accept voltages up to 5.5 V, allowing the device to translate down to VCC and operate in mixed 3.3-V/5-V system environments.
