74HC27BQ,115

Overview

The Nexperia 74HC27BQ,115 is a triple 3-input NOR gate manufactured in the DHVQFN14 (SOT762-1) package. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device features CMOS low power dissipation and high noise immunity. Static characteristics include input leakage currents up to ±1.0 μA at 6.0 V and supply currents up to 40 μA. Dynamic performance specifies propagation delays ranging from 8 ns to 135 ns depending on voltage and load conditions.

Feature Summary

• Triple 3-input NOR logic function with clamp diodes on inputs
• Wide supply voltage operation from 2.0 V to 6.0 V
• High noise immunity and low power CMOS technology
• ESD protection exceeding 2000 V (HBM) and 1000 V (CDM)

Applications

• General-purpose digital logic processing
• Signal gating and control circuits
• Interface logic for microcontrollers

Procurement Notes

Verify the specific ordering code against the manufacturer's current catalog to ensure compatibility with the DHVQFN14 package variant. Confirm that the required operating temperature range aligns with the specified -40 °C to +125 °C limits. Check for any recent product change notifications regarding material or manufacturing site updates before finalizing procurement specifications.

Selection Notes

Select this component when a triple 3-input NOR function is required in a compact surface-mount form factor. The DHVQFN14 package offers thermal enhancement suitable for dense PCB layouts. Ensure the system supply voltage remains within the 2.0 V to 6.0 V operational window to maintain valid logic levels and prevent damage to the internal CMOS structures.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices produced by Nexperia. It is designed as a drop-in replacement for equivalent industry-standard logic functions while offering improved packaging options like the leadless DHVQFN. The 'BQ' suffix specifically denotes the DHVQFN14 package configuration.

Replacement Considerations

Direct pin-compatible alternatives include the 74HC27PW in TSSOP14 and 74HC27D in SO14 packages from the same manufacturer family.
