SN74LVC373ANSR

Latches Overview

The SN74LVC373ANSR is an octal transparent D-type latch with three-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 back-drive protection.

Latches Procurement Notes

Verify the package type matches the NS (Small Outline) designation in the ordering suffix. Confirm the specific revision level required for your design. Ensure the operating temperature range meets system requirements. Check RoHS compliance status if applicable to your manufacturing process. Validate pinout compatibility during integration.

Latches Selection Notes

Select this component when an octal latch with three-state outputs is needed for bus interface applications. It is suitable for designs requiring voltage translation between 3.3-V and 5-V systems. Consider its high drive current for driving multiple loads. Evaluate its speed characteristics against system timing constraints. Verify power supply voltage ranges align with the target application.

Latches Part Context

This part belongs to the SNx4LVC373A family of octal transparent D-type latches with three-state outputs. It is designed for 1.65-V to 3.6-V VCC operation. The device is intended for use in applications where data needs to be retained or latched on a bus. It supports mixed-mode signal environments.

Latches FAQ

How does the Ioff feature benefit the SN74LVC373ANSR?

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

What is the function of the OE pin?

The OE (Output Enable) pin controls the output state. When high, outputs are in a high-impedance state; when low, outputs assume normal logic states based on the latch data.
