MM74HC32SJ

Inverter Gates Overview

The MM74HC32SJ 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 high noise immunity. Key electrical parameters include a typical propagation delay of 10 ns (maximum 18 ns at 5V) and a maximum quiescent current of 20 µA. Inputs are protected against static discharge via internal diode clamps.

Inverter Gates Feature Summary

• Utilizes advanced silicon-gate CMOS technology for high-speed operation comparable to LS-TTL gates combined with standard CMOS low power consumption.
• Features buffered outputs that provide high noise immunity and the ability to drive multiple LS-TTL loads.
• Includes internal diode clamps on all inputs to protect against damage caused by static discharge.

Inverter Gates Applications

• Digital logic circuits requiring Boolean OR functions
• Signal routing and switching applications
• General-purpose logic gate implementations in consumer electronics

Inverter Gates Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm RoHS compliance and lead-free status as specified in the datasheet. Ensure storage and handling procedures adhere to ESD protection standards due to the CMOS input structure. Validate package markings against the ordering information provided in the official documentation.

Inverter Gates Selection Notes

Select this component when a quad 2-input OR function is required in designs compatible with the 74HC logic family. It serves as a direct pin-out and functional replacement for standard 74LS series devices while offering lower power consumption. Consider the 2V to 6V supply range and -40°C to +85°C temperature rating for environmental suitability.

Inverter Gates Part Context

The MM74HC32SJ belongs to the 74HC series of logic integrated circuits produced by onsemi. This series is designed to be functionally and pin-out compatible with the legacy 74LS logic family. The 'SJ' suffix typically denotes a specific tape and reel packaging configuration for surface-mount assembly, distinct from tube-packaged variants like the MM74HC32M.

Inverter Gates Replacement Considerations

Public confirmed substitute part numbers include MM74HC32MX and MM74HC32MTCX from onsemi. Other manufacturers may offer equivalent 74HC32 devices, but verification of pin compatibility and electrical specifications against the original datasheet is required.
