74HCT32BQ,115

Overview

The Nexperia 74HCT32BQ,115 is a quad 2-input OR gate manufactured in the DHVQFN14 package (SOT762-1). It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features TTL input levels, symmetrical output impedance, and balanced propagation delays. Static characteristics include high noise immunity and latch-up performance exceeding 100 mA per JESD 78 Class II Level B. Dynamic performance at 4.5 V includes a typical propagation delay of 11 ns and transition time of 7 ns with a 50 pF load.

Feature Summary

• TTL-compatible input logic levels for direct interfacing with standard digital systems
• High noise immunity and robust latch-up protection exceeding industry standards
• Symmetrical output impedance ensuring balanced signal propagation

Applications

• General-purpose logic circuits requiring OR functionality
• Signal routing and data selection in digital systems
• Interface modules connecting TTL-level components

Selection Notes

Select this component when TTL input compatibility is required alongside CMOS drive capabilities. The DHVQFN14 package offers a compact footprint suitable for space-constrained designs. Ensure the application operates within the specified 4.5 V to 5.5 V supply range and temperature limits to maintain guaranteed electrical performance.

Part Context

This part belongs to the 74HCT series, which combines the low power consumption of CMOS technology with the noise immunity and speed of TTL logic. The 'BQ' designation indicates the DHVQFN14 leadless package variant, designed for surface-mount assembly with enhanced thermal properties compared to standard plastic packages.

Replacement Considerations

Compatible replacements include other 74HCT32 variants in different packages such as 74HCT32D (SO14) or 74HCT32PW (TSSOP14), provided pinout compatibility is verified. Cross-family alternatives like 74HC32 offer similar functionality but require CMOS-level input signals rather than TTL.
