74AHCT32BQ,115

Overview

The Nexperia 74AHCT32BQ,115 is a quad 2-input OR gate from the 74AHCT series. It operates on a supply voltage range of 4.5 V to 5.5 V with TTL input levels. The device features overvoltage tolerant inputs up to 5.5 V and balanced propagation delays. It utilizes DHVQFN14 packaging (SOT762-1) with dimensions of 2.5 x 3 x 0.85 mm. Static characteristics include low power dissipation and high noise immunity. Dynamic performance specifies propagation delays of up to 9.0 ns at 4.5 V to 5.5 V with 15 pF load capacitance across an operating temperature range of -40 °C to +125 °C.

Feature Summary

• Quad 2-input OR logic function with Schmitt-trigger action on all inputs
• Overvoltage tolerant inputs allowing interface in mixed voltage environments
• Balanced propagation delays for symmetrical signal timing
• High noise immunity with CMOS low power dissipation

Applications

• Mixed voltage logic translation between TTL and CMOS domains
• General purpose digital logic processing
• Signal routing in consumer electronics

Procurement Notes

Verify the specific ordering suffix matches the required package type and tape/reel configuration. Confirm RoHS compliance status and environmental declarations against current regulatory requirements. Ensure the component meets the specified temperature range and electrical parameters for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when TTL-compatible inputs are required within a 5 V system. The DHVQFN14 package offers space-saving benefits for surface-mount designs. Consider the overvoltage tolerance feature if interfacing directly with 5 V signals without additional level shifting components is necessary. Verify that the propagation delay specifications meet the timing constraints of the circuit design.

Part Context

This part belongs to the 74AHCT family, which combines the speed of Advanced High-speed CMOS technology with TTL-compatible input levels. The 'BQ' suffix indicates the DHVQFN14 leadless package variant. This series is designed for applications requiring robust performance in standard 5 V logic systems while maintaining low power consumption.

Replacement Considerations

Direct replacements include other 74AHCT32 variants in different packages such as SO14 or TSSOP14. Cross-reference with equivalent parts from other manufacturers offering quad 2-input OR gates in the 74HCT or 74AHCT families. Ensure pinout compatibility and electrical specifications match before substitution.
