MM74HC32SJX

Inverter Gates Overview

The MM74HC32SJX is a quad 2-input OR gate manufactured by Fairchild Semiconductor, belonging to the HC/UH series. It operates within a supply voltage range of 2V to 6V and features complementary outputs with a maximum static current of 2 µA. The device supports propagation delays of up to 17ns at 6V with 50pF load capacitance. It is housed in a 14-SOP package with a width of 5.30mm and functions across an operating temperature range of -40°C to 85°C.

Inverter Gates Feature Summary

• Provides four independent 2-input OR logic gates for signal processing
• Operates on standard CMOS technology with low power dissipation
• Features high noise immunity suitable for memory address decoding

Inverter Gates Applications

• Memory address decoding circuits
• Data routing applications
• General digital logic signal processing

Inverter Gates Procurement Notes

Verify the manufacturer origin as Fairchild Semiconductor or its successor entity, noting potential nomenclature changes from underscore to dash formats during integration. Confirm the specific suffix SJX corresponds to the 14-SOP lead-free package. Ensure compliance with RoHS standards and check for moisture sensitivity level 1 classification before procurement.

Inverter Gates Selection Notes

Select this component when a quad 2-input OR function is required in a compact surface-mount format. It serves as a direct replacement for other HC-series OR gates like the MM74HC32MX. Consider the 2V to 6V supply range and 17ns delay characteristics for timing-sensitive designs requiring low static power consumption.

Inverter Gates Part Context

This part belongs to the widely used 74HC logic family, known for compatibility with TTL loads and CMOS performance. The MM74HC32SJX specifically integrates four OR gates into a single 14-pin package, offering a space-efficient solution for complex digital systems requiring multiple logical OR operations without consuming excessive board area.

Inverter Gates Replacement Considerations

The MM74HC32MX is documented as a direct substitute. Other compatible options include Nexperia's 74HC32D and Texas Instruments variants. Verify pinout compatibility and electrical specifications when substituting with these alternatives.
