74HC373BQ,115

Latches Overview

The Nexperia 74HC373BQ,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 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features CMOS low power dissipation and high noise immunity. Static characteristics include input leakage current of ±1.0 μA max at 6.0 V and supply current of 160 μA max at 6.0 V. Dynamic propagation delay ranges from 12 ns to 45 ns depending on voltage and temperature.

Latches Feature Summary

• Octal D-type transparent latch architecture with 3-state non-inverting outputs
• Wide supply voltage compatibility ranging from 2.0 V to 6.0 V
• High noise immunity and robust latch-up performance exceeding 100 mA per JESD 78 Class II Level B
• Integrated ESD protection meeting ANSI/ESDA/JEDEC JS-001 class 2 and JS-002 class C3 standards

Latches Applications

• Bus-oriented applications requiring common 3-state output enable
• Mixed 5 V and 3.3 V system interfacing
• Industrial control systems operating within extended temperature ranges

Latches Procurement Notes

Verify the specific ordering suffix '115' corresponds to the DHVQFN20 package variant SOT764-1. Confirm that the application environment remains within the recommended operating conditions of 2.0 V to 6.0 V supply voltage and -40 °C to +125 °C ambient temperature. Ensure design safeguards account for the absolute maximum ratings to prevent permanent damage.

Latches Selection Notes

Select this component when an octal latch with 3-state outputs is required for bus-oriented designs. The HC logic family provides CMOS low power dissipation suitable for general-purpose digital applications. Verify that the DHVQFN20 package dimensions fit the PCB layout constraints and that the thermal performance meets the system's power dissipation requirements under maximum load conditions.

Latches Part Context

This part belongs to the 74HC/HCT373 family of octal D-type transparent latches. The 'BQ' designation specifically identifies the DHVQFN20 leadless package option. It shares functional compatibility with other variants like the SO20 and TSSOP20 packages but offers a smaller footprint suitable for space-constrained designs.

Latches Replacement Considerations

Direct pin-compatible replacements include other 74HC373 variants in different packages such as 74HC373D or 74HC373PW, provided the package outline matches the board design. Cross-family replacements like 74HCT373 require verification of TTL input level compatibility.
