MC74HC32AFEL

Inverter Gates Overview

The MC74HC32AFEL is a high-performance silicon-gate CMOS integrated circuit manufactured by onsemi. It functions as a quad 2-input OR gate, containing four independent logic channels within a single package. The device operates within a supply voltage range of 2.0 V to 6.0 V and features low input current of 1 µA. It provides an output drive capability sufficient for 10 LSTTL loads and exhibits high noise immunity characteristic of CMOS technology. The component is housed in a 16-SSOP surface-mount package.

Inverter Gates Feature Summary

• High-performance silicon-gate CMOS construction
• Outputs directly interface with CMOS, NMOS, and TTL logic families
• Compatible with standard CMOS outputs and LSTTL outputs when pullup resistors are used

Inverter Gates Applications

• Digital signal processing circuits requiring logical OR operations
• Interface modules connecting CMOS and TTL subsystems
• General-purpose logic control in consumer electronics

Inverter Gates Procurement Notes

Verify the specific suffix AFEL against the official datasheet to confirm the exact package type and tape/reel specifications. Confirm RoHS compliance status and environmental declarations prior to procurement. Ensure the source document matches the manufacturer's latest revision to avoid discrepancies in pinout or electrical characteristics.

Inverter Gates Selection Notes

Select this component when a quad 2-input OR function is required in mixed-voltage environments. It serves as a direct pin-compatible replacement for LS32 devices while offering improved noise immunity and lower power consumption typical of HC series technology. Verify that the 2V to 6V operating range aligns with the system power supply constraints.

Inverter Gates Part Context

This part belongs to the 74HC family of logic integrated circuits, which utilizes high-density silicon-gate CMOS technology. The 74HC32 series specifically implements the standard OR logic function across four independent channels. This family is widely recognized for its compatibility with legacy TTL systems while providing superior performance metrics compared to older transistor-transistor logic implementations.

Inverter Gates Replacement Considerations

The MC74HC32A is identified as having identical pinout to the LS32. Other compatible variants within the same product line include MC74HC32AD and MC74HC32ADG.
