Overview
The 74AHCT32D,112 is a quad 2-input OR gate manufactured by Nexperia USA Inc. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible input levels. The device provides balanced propagation delays with Schmitt-trigger actions on all inputs. It supports an ambient temperature range from -40 °C to +125 °C and includes overvoltage tolerant inputs up to 5.5 V. The component utilizes a 14-lead SO plastic small outline package (SOT108-1) with a body width of 3.9 mm.
Feature Summary
- Provides four independent 2-input OR logic functions in a single integrated circuit.
- Features TTL-compatible input levels for direct interfacing with Transistor-Transistor Logic systems.
- Incorporates Schmitt-trigger action on all inputs to ensure high noise immunity and clean signal transitions.
- Includes overvoltage tolerant inputs capable of handling voltages up to 5.5 V.
Applications
- Mixed voltage environments requiring level translation between CMOS and TTL logic families.
- Digital logic circuits implementing standard OR gate functionality.
- Signal processing applications demanding high noise immunity through Schmitt-trigger inputs.

Selection Notes
Select this component when TTL-level compatibility is required alongside CMOS performance characteristics. The AHCT series ensures seamless integration with legacy TTL outputs while maintaining low power dissipation typical of CMOS technology. Ensure the application environment stays within the specified -40 °C to +125 °C operating temperature range.
Part Context
This part belongs to the 74AHC/AHCT family of high-speed Si-gate CMOS devices. It is pin-compatible with Low-power Schottky TTL (LSTTL) standards. The product adheres to JEDEC standard No. 7-A specifications. The manufacturer reserves the right to make changes to information published in the data sheet without notice.
Replacement Considerations
Direct substitutes include the 74AHCT32PW,118 and 74AHCT32BQ,118 from Nexperia, which offer alternative packaging options such as TSSOP14 and DHVQFN14 respectively.
FAQ
What is the input voltage level specification for the 74AHCT32?
The 74AHCT32 variant specifies TTL-level input voltages, distinguishing it from the 74AHC32 which uses CMOS levels.
Does the device support overvoltage tolerant inputs?
Yes, the inputs are overvoltage tolerant to 5.5 V, allowing use in mixed voltage environments even if the supply voltage is lower.
