SN74LVC16373AGQLR

Latches Overview

The SN74LVC16373AGQLR is a 16-bit transparent D-type latch with 3-state outputs from the Texas Instruments Widebus family. It operates on a supply voltage of 1.65 V to 3.6 V and features inputs tolerant to 5.5 V, supporting mixed-mode signal operation. The device provides a maximum propagation delay of 4.2 ns at 3.3 V and includes Ioff circuitry for partial-power-down applications. It supports live-insertion and back-drive protection while maintaining 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 feature prevents damaging current backflow during power-down
• Supports live-insertion and back-drive protection

Latches Applications

• Servers
• Network switches
• Telecom infrastructures
• Buffer registers and bidirectional bus drivers

Latches Procurement Notes

Verify the specific package configuration against the datasheet pin assignments, as the GQL suffix indicates a Microstar Junior BGA variant. Confirm that the ordering suffix aligns with the required thermal and mechanical specifications for the target PCB layout. Ensure compliance with RoHS directives and moisture sensitivity levels specified in the packaging addendum before finalizing procurement orders.

Latches Selection Notes

Select this component when designing systems requiring high-speed data latching with mixed-voltage interface capabilities. The 5.5 V input tolerance allows direct interfacing with 5 V logic without level shifters. Consider the specific BGA footprint requirements and thermal dissipation characteristics inherent to the Microstar Junior package when evaluating board space constraints.

Latches Part Context

This part belongs to the SN74LVC16373A series, designed for high-density bus interface applications. The GQL suffix denotes a 56-ball Microstar Junior BGA package, distinct from standard TSSOP or SSOP variants. This form factor facilitates compact designs in portable electronics and wearable devices where minimal board area is critical.

Latches FAQ

How does the Ioff feature function?

The Ioff circuitry disables the outputs when VCC is 0 V, preventing damaging current backflow through the device during partial-power-down states.

What is the maximum propagation delay?

The maximum propagation delay (tpd) is 4.2 ns when operating at a supply voltage of 3.3 V.
