SN74AS32DR

Overview

The SN74AS32DR is a quadruple 2-input positive-OR gate manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of 0°C to 70°C. The device features a push-pull output stage with a high-level output current of -2 mA and a low-level output current of 20 mA. Propagation delays are specified as maximum 5.8 ns for both tPLH and tPHL under standard test conditions.

Feature Summary

• Contains four independent 2-input positive-OR gates performing Boolean functions Y = A + B
• Utilizes AS bipolar technology for high-speed logic operations
• Provides push-pull outputs capable of driving moderate loads

Applications

• Digital logic circuits requiring OR functionality
• Signal routing and selection networks
• Boolean logic implementation in industrial control systems

Procurement Notes

Verify the specific ordering suffix 'DR' corresponds to the SOIC package and tape-and-reel quantity. Confirm RoHS compliance status and lead finish details against the latest TI Package Option Addendum. Ensure the component meets the required commercial temperature range specifications for your application environment.

Selection Notes

Select this component when high-speed OR logic is required within the 74AS family. Compare propagation delay and power consumption against SN74ALS32 variants if lower power is prioritized over speed. Verify that the 14-pin SOIC footprint matches the target PCB layout constraints.

Part Context

This part belongs to the SN54/74AS series of quadruple 2-input positive-OR gates. It is functionally equivalent to other SN74AS32 variants but differs in packaging and reel configuration. The 'DR' suffix specifically denotes the Small Outline Integrated Circuit (D) package supplied in large tape-and-reel format.

Replacement Considerations

SN74AS32NSR serves as a direct replacement offering the same logic function in a narrow SOP package.
