SN74HCT32ANSR

Inverter Gates Overview

The SN74HCT32ANSR is a quadruple 2-input positive-OR gate from the Texas Instruments HCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of -40°C to +85°C. The device features four independent OR gates, providing outputs capable of driving up to 10 LSTTL loads with ±4-mA drive current at 5 V. Typical propagation delay is 13 ns, with maximum values reaching 27 ns at 5.5 V. Input current is limited to 1 µA max, and typical supply current is 20 µA.

Inverter Gates Feature Summary

• Contains four independent 2-input OR gates performing Boolean function Y = A + B
• TTL-voltage compatible inputs allow direct interfacing with TTL systems
• Outputs can drive up to 10 LSTTL loads
• Low power consumption with 20-µA maximum ICC

Inverter Gates Applications

• Boolean logic implementation in digital circuits
• Signal routing and selection using OR functions
• Interfacing between TTL and CMOS logic domains

Inverter Gates Procurement Notes

Verify the package type matches the design requirements, as the NS suffix indicates a Small Outline (SO) package. Confirm RoHS compliance and moisture sensitivity level ratings before procurement. Ensure the ordering part number corresponds to the specific tape and reel quantity required for assembly processes. Check for any recent documentation updates or revision history changes that may affect pinout or electrical characteristics.

Inverter Gates Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS low-power operation. The HCT series ensures compatibility with standard TTL voltage levels while maintaining lower static power consumption compared to older LS families. Consider the SOIC-14 package dimensions and thermal resistance values if high-density mounting or specific thermal management strategies are necessary for the application environment.

Inverter Gates Part Context

The SN74HCT32ANSR belongs to the SNx4HCT32 family of quadruple 2-input positive-OR gates. It is part of Texas Instruments' broader HCT logic portfolio, designed to bridge the gap between TTL and CMOS technologies. The 'ANSR' designation specifies the SO (Small Outline) package variant with a reel carrier format, distinguishing it from other packaging options like SOIC, SSOP, or TSSOP available within the same logical function family.
