MM74HC32MX

Inverter Gates Overview

The MM74HC32MX is a quad 2-input OR gate manufactured by Fairchild Semiconductor, belonging to the HC logic series. It operates within a supply voltage range of 2 V to 6 V and supports surface mount installation in an SOIC-Narrow-14 package. The device features four independent gates with eight inputs and four outputs. Electrical characteristics include a low-level output current of 5.2 mA and a high-level output current of -5.2 mA. Propagation delay is specified at 9 ns, with an operating temperature range from -40 °C to +85 °C.

Inverter Gates Feature Summary

• Contains four independent 2-input OR logic functions within a single integrated circuit.
• Utilizes advanced silicon-gate CMOS technology for high noise immunity and low power consumption.
• Provides standard TTL-compatible drive capability for interfacing with legacy logic families.

Inverter Gates Applications

• General-purpose digital logic signal processing
• Data routing and selection circuits
• Address decoding systems

Inverter Gates Procurement Notes

Verify the manufacturer designation on the component marking, as this part number is also produced by onsemi following corporate acquisitions. Confirm the specific suffix indicates the correct tape-and-reel packaging configuration required for automated assembly processes. Ensure compliance with RoHS directives if environmental regulations apply to the final product design.

Inverter Gates Selection Notes

Select this component when a compact solution for multiple OR operations is required in space-constrained designs. The HC series offers speed performance comparable to low-power Schottky TTL while maintaining CMOS power efficiency. Consider the SOIC-14 package dimensions against available PCB real estate and verify that the 2 V to 6 V supply range aligns with the system's power architecture.

Inverter Gates Part Context

This device is part of the broader MM74HC32 family of quad 2-input OR gates. It shares functional compatibility with other members of the 74HC series, allowing for pin-to-pin substitution in many designs where minor electrical parameter differences are acceptable. The 'M' suffix typically denotes the SOIC-14 surface-mount package variant.

Inverter Gates Replacement Considerations

The MM74HC32MX_NL is a documented alias for this component. Other manufacturers produce electrically equivalent parts under the generic 74HC32 designation, though exact pinout and electrical specifications should be verified against official datasheets before implementation.
