CD74AC32M

Inverter Gates Overview

The CD74AC32M is a quad 2-input OR gate manufactured by Harris Corporation, belonging to the AC series of CMOS logic devices. It operates within a supply voltage range of 2V to 6V and features four independent logic channels. The component utilizes a 14-pin Small Outline Integrated Circuit (SOIC) package with a width of 0.295 inches (7.50mm). Designed for high-speed applications, it supports operation temperatures from -55°C to 125°C. The device provides standard TTL-compatible inputs and outputs, ensuring compatibility with various digital systems.

Inverter Gates Feature Summary

• Quad configuration providing four independent 2-input OR logic functions in a single package
• High-speed AC series CMOS technology enabling rapid signal processing
• Wide operating temperature range suitable for demanding industrial environments
• TTL-compatible input and output levels for seamless integration

Inverter Gates Applications

• Digital logic circuit design requiring multiple OR gates
• Signal routing and selection in electronic systems
• Industrial control panels and automation equipment
• Consumer electronics utilizing high-speed logic processing

Inverter Gates Procurement Notes

Verify the manufacturer origin, as Texas Instruments datasheets may list this part due to acquisition history. Confirm RoHS compliance status, as older Harris Semiconductor parts often lack modern environmental certifications. Ensure the SOIC-14 package matches your PCB footprint requirements. Check for obsolescence status, as Harris Corporation logic products may be discontinued or replaced by newer equivalents.

Inverter Gates Selection Notes

Select the CD74AC32M when multiple OR gates are required in a compact form factor. Consider the AC series speed characteristics against HC or HCT alternatives based on switching frequency needs. Verify voltage compatibility, as the 2V-6V range differs from standard 5V-only logic families. Evaluate thermal performance if operating near the upper temperature limit of 125°C.

Inverter Gates Part Context

Harris Corporation was a prominent semiconductor manufacturer before its acquisition by Intersil, which later merged with Renesas Electronics. The CD74 prefix indicates commercial temperature range and CMOS technology. The AC series represents an advancement over earlier HMOS technologies, offering improved speed and lower power consumption. This specific part number reflects legacy manufacturing standards common in industrial and military-grade electronics from the late 20th century.

Inverter Gates Replacement Considerations

Check for direct pin-compatible replacements such as SN74AC32N or SN74AC32D from Texas Instruments. Verify electrical specifications match, particularly propagation delay and output drive current. Ensure package dimensions align if physical replacement is necessary without PCB redesign.
