CD74HCT32ME4

Inverter Gates Overview

The CD74HCT32ME4 is a high-speed CMOS logic device containing four independent 2-input OR gates. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an extended temperature range from -55°C to +125°C. The component features LSTTL-compatible inputs with a maximum low-level input voltage of 0.8 V and a minimum high-level input voltage of 2 V. Propagation delay is specified at 24 ns under typical conditions with a 50 pF load. It utilizes a 14-pin SOIC package.

Inverter Gates Feature Summary

• Contains four independent 2-input OR gates performing the Boolean function Y = A + B
• Features buffered TTL-compatible CMOS inputs for compatibility with older bipolar logic devices
• Provides balanced CMOS push-pull outputs capable of sinking and sourcing similar currents

Inverter Gates Applications

• Monitoring error signals using fewer inputs
• Combining active-low enable signals
• Creating multi-input OR gate functions by combining multiple channels

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'M' corresponds to the SOIC-14 package variant when procuring. Confirm RoHS compliance status and lead finish details against the manufacturer's current orderable addendum, as packaging materials may vary. Ensure the procurement documentation matches the exact part number to avoid receiving alternative package types such as PDIP or CDIP.

Inverter Gates Selection Notes

Select this component for designs requiring quad 2-input OR logic with HCT speed and compatibility. It is suitable for systems operating strictly between 4.5 V and 5.5 V. Consider the wide industrial temperature range if the application involves extreme environments. Verify that the required propagation delay meets the system timing constraints before finalizing the selection.

Inverter Gates Part Context

This device belongs to the Texas Instruments CD74HCT32 family of quadruple 2-input OR gates. It is part of the broader HCT logic series, designed to bridge the gap between standard CMOS performance and LSTTL interface requirements. The family includes various package options including PDIP, SOIC, and CDIP configurations.

Inverter Gates Replacement Considerations

Direct substitutes include other CD74HCT32 variants in different packages, such as CD74HCT32E (PDIP) or CD74HCT32EE4 (PDIP). Cross-series replacements like SN74HCT32ANSR are available but differ in package type and operating temperature range.
