SN74LVC373ANSRG4

Latches Overview

The SN74LVC373ANSRG4 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 output drive currents of ±24 mA. It includes Ioff circuitry for partial-power-down mode and back-drive protection, along with ESD protection exceeding 2000 V via the human-body model.

Latches Feature Summary

• Inputs accept voltages up to 5.5 V for mixed-mode compatibility
• Ioff feature supports live-insertion and back-drive protection
• High ESD protection ratings across multiple testing models

Latches Applications

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

Latches Procurement Notes

Verify the package type corresponds to the NS (SOP) designation when sourcing this specific part number variant. Confirm that the ordering suffix matches the required reel quantity and lead finish specifications. Ensure the component meets RoHS compliance requirements if mandated by the design. Cross-reference the manufacturer's latest orderable addendum for current availability status and packaging details before finalizing procurement plans.

Latches Selection Notes

Select this component for applications requiring high-speed data latching in low-voltage environments. The 5.5 V tolerant inputs facilitate interface between 3.3 V logic and 5 V systems without additional level shifters. The 3-state outputs allow direct connection to bus lines, reducing external component count. Consider the thermal performance and operating temperature range suitable for the intended industrial or commercial environment.

Latches Part Context

This device belongs to the SNx4LVC373A family of octal transparent D-type latches. It shares functional characteristics with other members of the LVC series, offering similar pinouts and electrical behaviors. The family is designed for CMOS technology applications requiring high drive capability and low power consumption. Variations exist primarily in package styles and specific ordering suffixes rather than core functionality.

Latches FAQ

How does the Ioff feature benefit the SN74LVC373ANSRG4?

The Ioff circuitry disables the outputs when the device is powered down, preventing damaging current backflow through the device. This supports partial-power-down modes and live-insertion applications.

What is the maximum input voltage tolerance?

The inputs can 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 even when VCC is lower.
