SN74LV373APWG4

Latches Overview

The SN74LV373APWG4 is an octal transparent D-type latch manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 5.5V and supports mixed-mode port operation across all ports. The device features three-state outputs with Ioff support for partial power-down mode. It exhibits low output impedance designed to drive CMOS, LSTTL, or HC/HTTL loads. Typical specifications include an output ground bounce (VOLP) of less than 0.8V at VCC = 3.3V and an output overshoot (VOHV) of less than 2.3V under the same conditions. The component is housed in a TSSOP-20 package.

Latches Feature Summary

• Supports mixed-mode voltage operation on all ports

Latches Procurement Notes

Verify the complete part number including the G4 suffix to confirm RoHS compliance and green manufacturing status. Ensure the TSSOP-20 package variant matches the design footprint. Confirm that the operating temperature range aligns with system thermal requirements. Validate that the 2V to 5.5V supply voltage range is compatible with the target power rails. Check for specific tape-and-reel or tube packaging preferences during ordering.

Latches Selection Notes

Select this component when an octal latch with mixed-voltage compatibility is required. The Ioff feature makes it suitable for systems needing partial power-down capabilities. Verify that the three-state output configuration meets bus architecture needs. Ensure the TSSOP-20 package fits the available PCB space. Confirm that the 2V to 5.5V operating range covers the system's voltage variations.
