74ALVC373BQ,115

Latches Overview

The Nexperia 74ALVC373BQ,115 is an octal D-type transparent latch with 3-state outputs housed in a DHVQFN20 package (SOT764-1). It operates on a supply voltage range of 1.65 V to 3.6 V and supports an ambient temperature range from -40 °C to +125 °C. The device features Schmitt trigger inputs for slow signal tolerance and includes IOFF circuitry for partial power-down applications. Propagation delays vary by voltage: Dn to Qn ranges from 1.0 ns to 6.2 ns; LE to Qn ranges from 1.0 ns to 6.9 ns; OE to Qn enable time ranges from 1.0 ns to 7.4 ns.

Latches Feature Summary

• Octal D-type transparent latch architecture with 3-state outputs controlled by Latch Enable (LE) and Output Enable (OE) inputs.
• Schmitt trigger action on all inputs provides tolerance for slow rise and fall times.
• IOFF circuitry disables outputs to prevent damaging backflow current during partial power-down conditions.

Latches Applications

• Parallel data storage
• Bus-oriented memory mapping
• Clock buffering

Latches Procurement Notes

Verify the ordering suffix '115' corresponds to the DHVQFN20 package variant SOT764-1. Confirm that the required operating temperature range aligns with the specified -40 °C to +125 °C limits. Ensure input transition rates comply with recommended operating conditions to maintain timing specifications.

Latches Selection Notes

Select this component when an octal latch with high-speed performance and low power consumption is required. The ALVC family offers faster propagation delays compared to standard LVC variants. Verify that the system voltage falls within the 1.65 V to 3.6 V range and that the DHVQFN20 package fits the PCB layout constraints.

Latches Part Context

This part belongs to the Nexperia 74ALVC series of logic devices. It is functionally similar to other octal latches but distinguished by its specific package type and speed characteristics. The 'BQ' suffix indicates the DHVQFN20 leadless package, while '115' denotes the tape and reel packaging format.

Latches Replacement Considerations

Direct pin-compatible replacements include other 74ALVC373 variants in different packages, such as 74ALVC373D or 74ALVC373PW, provided the package footprint allows for substitution. Cross-family replacements like 74LVC373 may require voltage level verification.
