SN74ACT32D

Overview

The SN74ACT32D is a quad 2-input positive-OR gate from the Texas Instruments ACT logic series. It operates within a supply voltage range of 4.5 V to 5.5 V and features low static current consumption of 2 µA maximum. The device provides high noise immunity and supports loads up to 10 LSTTL equivalents. Key electrical parameters include a propagation delay of 10 ns at 5 V with 50 pF load, and output drive currents of ±24 mA. It is housed in a 14-pin SOIC package.

Feature Summary

• Quad configuration providing four independent 2-input OR gates in a single package
• ACT series technology ensuring high-speed operation with low power dissipation
• Robust output drive capability supporting standard TTL loads

Applications

• Data acquisition systems requiring logical OR operations
• Industrial control logic interfaces
• Telecommunications equipment signal processing

Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence notices. Confirm package integrity and pin alignment upon receipt. Ensure storage conditions comply with moisture sensitivity level requirements to prevent damage during soldering processes.

Selection Notes

Select this component for applications requiring moderate speed and standard voltage levels. Compare against SN74ACT32DRG4 for tape-and-reel packaging options or SN74ACT32PWR for TSSOP variants. Evaluate thermal management needs based on the SOIC package's thermal resistance characteristics.

Part Context

This device belongs to the SN74ACT family, which combines advanced CMOS technology with TTL-compatible inputs. It offers faster switching speeds than standard LS series while maintaining lower power consumption than AS series devices. The ACT series is designed for general-purpose digital logic applications requiring reliable performance.

Replacement Considerations

SN74ACT32DRG4 (Tape & Reel), SN74ACT32PWR (TSSOP Package). Verify pinout compatibility and electrical specifications before substitution.
