SN74LVC16373AZRDR

Latches Overview

The SN74LVC16373A 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 circuitry for partial-power-down support and provides ESD protection exceeding 2000 V via the human-body model.

Latches Feature Summary

• Operates within a wide voltage range from 1.65 V to 3.6 V
• Inputs accept voltages up to 5.5 V for mixed-mode compatibility
• Ioff feature prevents back-drive current during power-down
• High drive capability supports bus interface applications

Latches Applications

• Servers
• Network switches
• Buffer registers
• Bidirectional bus drivers

Latches Procurement Notes

Verify the specific package variant (TSSOP, TVSOP, SSOP, or Microstar Junior) matches the design requirements. Confirm RoHS compliance and lead finish specifications in the orderable addendum. Ensure the ordering suffix aligns with the desired carrier type and moisture sensitivity level before finalizing procurement.

Latches Selection Notes

Select this component for high-speed data latching in low-voltage systems requiring 5-V tolerant inputs. The 3-state outputs facilitate bus sharing without external pull-up components. Consider thermal resistance metrics if operating near the upper temperature limits. Verify that unused inputs are tied to defined logic levels to prevent undefined states.

Latches Part Context

This device belongs to the SN74LVC16373A family of 16-bit latches. It is designed for use in portable and battery-powered applications due to its low-voltage operation. The Widebus family designation indicates optimized performance for wide data buses in modern digital systems.

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 scenarios.

Can this device translate between voltage domains?

Yes, the inputs accept voltages up to 5.5 V, allowing the device to be used as a translator in mixed 3.3-V/5-V system environments.
