74ALVC373D,112

Latches Overview

The Nexperia 74ALVC373D,112 is an octal D-type transparent latch with 3-state outputs housed in a SOIC-20 package. It operates within a supply voltage range of 1.65 V to 3.6 V and supports temperatures from -40 °C to +125 °C. Propagation delays range from 1.0 ns to 6.9 ns depending on voltage and temperature. The device features Schmitt trigger inputs for noise tolerance and IOFF circuitry for partial power-down applications.

Latches Feature Summary

• Octal D-type transparent latch architecture with 3-state outputs
• Schmitt trigger action on all inputs for slow rise/fall time tolerance
• IOFF circuitry prevents backflow current during partial power-down
• Overvoltage tolerant inputs compatible with mixed voltage environments

Latches Applications

• Bus-oriented data storage and buffering
• Mixed 3.3 V and 5 V system translation
• Partial power-down mode operation in portable electronics

Latches Procurement Notes

Verify the specific ordering suffix '112' against official Nexperia documentation to confirm tape-and-reel packaging specifications. Confirm that the SOIC-20 (SOT163-1) package variant matches the design requirements. Ensure compliance with RoHS and REACH directives as stated in the product data sheet before final procurement.

Latches Selection Notes

Select this component when an octal latch with high-speed performance and low power consumption is required. The ALVC series offers faster propagation delays compared to standard LV or HC families. Verify input/output voltage compatibility with the target logic levels and ensure the operating temperature range meets the environmental constraints of the application.

Latches Part Context

This part belongs to the Nexperia 74ALVC family of advanced low-voltage CMOS logic devices. The 74ALVC373 specifically provides eight D-type latches with three-state outputs. It is designed for high-speed applications requiring low power dissipation and wide supply voltage flexibility, serving as a bridge between different logic voltage domains in complex digital systems.

Latches Replacement Considerations

The 74ALVC373PW (TSSOP20) and 74ALVC373BQ (DHVQFN20) are alternative package options for the same logical function. Cross-reference pinouts and thermal characteristics when substituting packages. Ensure any replacement maintains the 1.65 V to 3.6 V supply range and -40 °C to +125 °C temperature specification.
