SN74LV373ADGSR

Latches Overview

The SN74LV373ADGSR is an octal transparent D-type latch with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and features a maximum propagation delay of 8.5 ns at 5 V. The device supports mixed-mode voltage operation on all ports, allowing inputs to accept voltages up to 5.5 V regardless of the VCC level. It includes Ioff support for partial-power-down mode and exhibits latch-up performance exceeding 250 mA per JESD 17 standards.

Latches Feature Summary

• Supports mixed-mode voltage operation across all ports
• Enables partial-power-down mode via Ioff support
• Provides high-impedance state control through buffered output-enable input

Latches Applications

• Printers
• Network switches
• Tests and measurements
• Wireless infrastructure
• Motor controls

Latches Procurement Notes

Verify that the component matches the SN74LV373ADGSR designation specifically, as suffixes indicate package variations. Confirm RoHS compliance and lead finish details against the manufacturer's latest documentation. Ensure the procurement source provides valid traceability data consistent with Texas Instruments production standards.

Latches Selection Notes

Select this component when designing systems requiring octal latching with bus interface capabilities in low-voltage environments. The wide operating voltage range facilitates down-voltage translation applications. Consider the specific thermal requirements and layout guidelines provided in the datasheet to ensure signal integrity and proper power distribution during operation.

Latches Part Context

This part belongs to the SN74LV373A family of octal transparent D-type latches. The 'DGSR' suffix identifies the specific VSSOP (DGS) 20-pin surface-mount package configuration. This variant is designed for automated assembly processes using tape and reel packaging, distinguishing it from tube or other carrier options available within the same logic family.

Latches FAQ

How does the Output Enable (OE) pin affect internal latch operations?

The OE pin controls the external output state but does not affect the internal operations of the latches. Data can be entered or retained while outputs are in the high-impedance state.

What is the behavior of the Q outputs when the Latch Enable (LE) input is low?

When LE is taken low, the Q outputs are latched at the logic levels set up at the D inputs at that moment.
