SN74AHCT32PWR

Overview

The SN74AHCT32PWR is a quad 2-input 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. Propagation delay is specified at 5.5 ns under typical conditions, ensuring fast switching performance. It is housed in a 14-TSSOP surface-mount package and supports an extended operating temperature range from -55°C to +125°C.

Feature Summary

• Provides four independent 2-input OR logic functions for signal processing
• Ensures compatibility with standard CMOS logic families through HCT input structures
• Delivers robust output drive strength suitable for driving multiple loads

Applications

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

Procurement Notes

Verify the specific suffix PWR corresponds to the TSSOP-14 package configuration when sourcing. Confirm RoHS compliance status as per the manufacturer's latest documentation. Ensure the ordering part number matches the required tape-and-reel quantity specifications for automated assembly processes.

Selection Notes

Select this component when a quad OR gate is required with HCT-compatible inputs for interfacing with older TTL or standard CMOS logic families. The wide operating temperature range makes it suitable for harsh environments. Verify that the 5.5 V supply voltage aligns with the system design requirements before integration.

Part Context

This component belongs to the SN74AHCT32 family of single-function gates manufactured by Texas Instruments. It is designed for high-speed digital applications requiring reliable OR logic operations. The AHCT series bridges the gap between AHC speed and HCT voltage compatibility, offering versatile integration options in mixed-voltage digital designs.

Replacement Considerations

Direct substitutes include other SN74AHCT32 variants with different packaging options such as SN74AHCT32D or SN74AHCT32N. Cross-reference pinouts and electrical characteristics to ensure functional equivalence in existing circuit layouts.
