SN74AHCT32PW

Overview

The SN74AHCT32PW is a quad 2-input positive-OR gate from the Texas Instruments SN74AHCT32 series. It operates within a supply voltage range of 4.5 V to 5.5 V and features low static power consumption with a maximum quiescent current of 2 µA. The device provides symmetrical output drive capabilities, delivering 8 mA at both high and low logic levels. It utilizes TSSOP-14 surface-mount packaging and supports propagation delays of up to 7.9 ns at 5 V with a 50 pF load. The component is designed for industrial temperature ranges, functioning reliably between -40°C and +85°C.

Feature Summary

• Provides four independent 2-input OR logic functions in a single integrated circuit package.
• Ensures compatibility with standard CMOS logic outputs through AHCT input structures.
• Maintains low static power dissipation suitable for energy-efficient digital designs.

Applications

• Digital signal routing and selection circuits
• Address decoding logic in embedded systems
• Control logic interfaces for peripheral devices

Procurement Notes

Verify the specific suffix against official datasheets to confirm exact operating temperature ranges and package variations. Ensure that the ordering information matches the required logic family specifications for your design. Cross-reference manufacturer part numbers with distributor listings to confirm availability and authenticity before procurement.

Selection Notes

Select this component when designing systems requiring multiple OR gates with CMOS-compatible inputs and 5 V operation. Consider the TSSOP-14 package constraints for PCB layout and thermal management. Evaluate the propagation delay characteristics against system timing requirements to ensure signal integrity across all channels.

Part Context

This part belongs to the SN74AHCT32 family of logic gates, which are widely used in general-purpose digital applications. The AHCT series bridges the gap between advanced high-speed CMOS technology and standard TTL logic levels, ensuring broad interoperability with legacy systems while offering improved performance metrics over older generations.

Replacement Considerations

Compatible alternatives include the SN74AHCT32PWR and SN74AHCT32PWRE4. Verify pinout compatibility and electrical specifications before substitution to maintain circuit functionality without redesigning the board layout or adjusting power supply requirements.
