MC74HC32A is a quad 2-input OR gate produced by ON Semiconductor. It has good noise immunity and can be directly interfaced with CMOS, NMOS and TTL.
The MC74HC32A quad 2‑input OR gate is compatible with LS‑TTL, CMOS, NMOS and standard CMOS outputs. It offers low input current (1 µA) and high noise immunity, meeting JEDEC standard No. 7A. Key features include a 2.0‑6.0 V operating voltage range and the ability to drive up to 10 LSTTL loads.
The device is offered in several package types—PDIP‑14, SOIC‑14, TSSOP‑14 and SOEIAJ‑14—each with detailed dimensions and ordering information. Ordering numbers and Pb‑free options are provided, and the datasheet includes pinout diagrams, marking codes, and electrical characteristics for design reference.
