SN74LVC373APWR

Latches Overview

The SN74LVC373APWR 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 typical output ground bounce of 2 V. It includes Ioff support for partial-power-down mode and back-drive protection. The component is housed in a 20-pin TSSOP package.

Latches Feature Summary

• Operates within a wide supply voltage range of 1.65 V to 3.6 V
• Inputs accept voltages up to 5.5 V for mixed-mode compatibility
• Supports live-insertion and partial-power-down modes via Ioff circuitry
• Provides high drive capability suitable for bus interfaces

Latches Applications

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

Latches Procurement Notes

Verify the specific ordering suffix 'PWR' corresponds to the 20-pin TSSOP package and tape-and-reel carrier configuration. Confirm that the RoHS status and lead finish (NIPDAU) align with project requirements. Ensure the operating temperature range of -40°C to 125°C meets environmental specifications. Cross-reference the datasheet revision date to ensure current electrical characteristics are applied.

Latches Selection Notes

Select this component when an octal latch with 3-state outputs is required for high-speed data retention. It is suitable for applications needing voltage translation between 3.3-V and 5-V systems due to its 5.5-V tolerant inputs. Consider the TSSOP package dimensions and thermal resistance if space or heat dissipation is constrained. Verify that the 24 mA output drive current matches the load requirements.

Latches Part Context

This part belongs to the SNx4LVC373A family of octal transparent D-type latches. It shares functional similarities with other variants like SN74LVC373ADW and SN74LVC373ARGYR, differing primarily in packaging and reel specifications. The LVC series is designed for low-voltage CMOS applications requiring high speed and low power consumption.

Latches Replacement Considerations

SN74LVC373APW is a tube-packaged equivalent in the same TSSOP-20 footprint. SN74LVC373ADBR offers the same functionality in an SSOP-20 package.
