SN74LVC373APWTE4

Latches Overview

The SN74LVC373APWTE4 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 provides high drive current capability of 24 mA. It includes Ioff circuitry for partial-power-down mode and offers ESD protection exceeding 2000 V via the human-body model. The component is housed in a 20-pin TSSOP package.

Latches Feature Summary

• Operates within a wide voltage range of 1.65 V to 3.6 V while accepting 5-V inputs
• Features Ioff support to prevent back-drive current during partial-power-down states
• Provides high-output drive capability suitable for bus interface applications
• Includes robust electrostatic discharge protection across multiple testing models

Latches Applications

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

Latches Procurement Notes

Verify the specific ordering suffix 'E4' against the manufacturer's latest documentation to confirm lead-free status and RoHS compliance details. Ensure the TSSOP-20 package dimensions match the design constraints. Confirm that the device status remains active production rather than obsolete or preproduction before finalizing procurement plans.

Latches Selection Notes

Select this component when designing systems requiring octal data latching with tri-state output control. It is suitable for environments needing translation between 3.3-V and 5-V logic levels due to its input tolerance. Consider the 6.8 ns propagation delay for timing-critical paths and ensure the power supply stays within the 1.65 V to 3.6 V operating range.

Latches Part Context

This part belongs to the SNx4LVC373A family of octal transparent D-type latches with 3-state outputs. The family shares identical electrical characteristics and functional descriptions but differs in packaging options such as SSOP, SOIC, PDIP, and VQFN. The PW suffix specifically denotes the Thin-Shrink Small-Outline Package (TSSOP) variant.

Latches FAQ

How does the Ioff feature function?

The Ioff circuitry disables the outputs when the device is powered down, preventing damaging current backflow through the device when VCC is 0 V.

What is the maximum input voltage tolerance?

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.
