SN74LVC373APWT

Latches Overview

The SN74LVC373APWT is an octal transparent D-type latch with 3-state outputs manufactured by Texas Instruments. It operates from a supply voltage of 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 6.8 ns at 3.3 V and typical output ground bounce of 2 V. It supports live-insertion and partial-power-down modes via Ioff circuitry. Packaged in a TSSOP-20 housing, it provides high drive current capability for bus interface applications.

Latches Feature Summary

• Operates within a wide supply 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 backflow during partial-power-down states
• Latch-up performance exceeds 250 mA per JESD 17 standards

Latches Applications

• Network switches
• TV set-top boxes
• Motor drives
• PCs and notebooks

Latches Procurement Notes

Verify the specific ordering suffix 'T' indicates tape-and-reel packaging containing 250 units per carrier. Confirm the package type corresponds to the TSSOP (PW) variant with 20 pins. Ensure compliance with RoHS directives and Level-1 moisture sensitivity rating for standard surface-mount assembly processes.

Latches Selection Notes

Select this component when an octal latch with 3-state outputs is required for systems operating between 1.65 V and 3.6 V. It is suitable for designs needing 5.5 V tolerant inputs to interface with higher voltage logic levels. Consider the TSSOP-20 package dimensions and thermal characteristics for PCB layout constraints.

Latches Part Context

This part belongs to the SNx4LVC373A family of octal transparent D-type latches. The family includes variants with different package options such as SSOP, SOIC, PDIP, and VQFN. All variants share identical electrical specifications and functional behavior, differing only in physical housing and reel/tube packaging configurations.

Latches Replacement Considerations

SN74LVC373APW is the tube-packaged equivalent. SN74LVC373ARGYR offers a VQFN alternative.
