MM74HC32M

Inverter Gates Overview

The MM74HC32M is a quad 2-input OR gate manufactured by onsemi, utilizing advanced silicon-gate CMOS technology. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range from -40°C to +85°C. The device features buffered outputs capable of driving 10 LS-TTL loads with low quiescent current. Key electrical parameters include a typical propagation delay of 10 ns (maximum 18 ns at 5 V) and maximum input current of ±1.0 µA.

Inverter Gates Feature Summary

• Advanced silicon-gate CMOS technology providing high noise immunity and low power consumption
• Functionally and pinout compatible with the standard 74LS logic family
• Buffered outputs designed to drive 10 LS-TTL loads
• Internal diode clamps protect all inputs from static discharge damage

Inverter Gates Applications

• Digital logic circuits requiring OR functionality
• Signal routing and selection systems
• General-purpose logic applications compatible with LS-TTL standards

Inverter Gates Procurement Notes

Verify the specific package variant during procurement, as the MM74HC32M designation corresponds to the SOIC-14 tube packaging in official documentation. Confirm RoHS compliance status and ensure the ordering suffix matches the required shipping format, such as tubes for standard quantities or tape and reel for bulk orders.

Inverter Gates Selection Notes

Select this component when a quad 2-input OR gate is required with compatibility to existing 74LS designs. It is suitable for applications needing wide supply voltage flexibility between 2 V and 6 V. Ensure the design accounts for the specified propagation delays and output drive capabilities under the intended load conditions.

Inverter Gates Part Context

This part belongs to the MM74HC32 series, which includes variants like MM74HC32MX and MM74HC32MTCX. These devices share identical logical functions but differ in packaging options, including SOIC-14 and TSSOP-14 configurations. The series represents onsemi's implementation of the standard 74HC logic family for general-purpose digital applications.

Inverter Gates Replacement Considerations

Direct replacement parts include MM74HC32MX and MM74HC32MTCX from onsemi. Cross-manufacturer equivalents such as Nexperia 74HC32D are also documented as direct substitutes.
