74AHC32D,112

Overview

The Nexperia 74AHC32D,112 is a quad 2-input OR gate manufactured by Nexperia USA Inc. It operates within a supply voltage range of 2.0 V to 5.5 V and features overvoltage tolerant inputs up to 5.5 V. The device utilizes CMOS technology for low power dissipation and high noise immunity. It includes Schmitt-trigger actions on all inputs and provides balanced propagation delays. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). Latch-up performance exceeds 100 mA per JESD 78 Class II Level A. The component is specified for ambient temperatures from -40 °C to +125 °C.

• Quad 2-input OR logic function with balanced propagation delays
• Overvoltage tolerant inputs allowing use in mixed voltage environments
• Schmitt-trigger actions on all inputs for improved noise immunity
• High ESD protection exceeding 2000 V HBM and 1000 V CDM

Applications

• Mixed voltage translation interfaces
• General purpose digital logic circuits
• Signal processing applications requiring high noise immunity

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure package compatibility and availability status. Confirm that the procurement channel sources directly from authorized distributors or the manufacturer to guarantee authenticity. Check for any recent product change notices regarding marking or packaging updates before finalizing orders.

Selection Notes

Select this component when a quad 2-input OR gate is required with wide supply voltage flexibility between 2.0 V and 5.5 V. The overvoltage tolerant inputs make it suitable for interfacing with different logic families without additional level shifting components. Ensure the application environment stays within the specified temperature range of -40 °C to +125 °C for optimal performance.

Part Context

This part belongs to the 74AHC/AHCT32 family of high-speed Si-gate CMOS devices. It is pin compatible with Low-power Schottky TTL (LSTTL) standards. The 'D' suffix indicates the SO14 plastic small outline package (SOT108-1), which has a body width of 3.9 mm and 14 leads. This series complies with JEDEC standard No. 7-A.

Replacement Considerations

The 74AHCT32D variant serves as a functional substitute within the same package if TTL input levels are preferred over CMOS levels. Other package options like TSSOP14 (PW) or DHVQFN14 (BQ) offer physical alternatives but require layout adjustments.
