Overview
The SN74AC32DR is a quadruple 2-input positive-OR gate from the Texas Instruments 74AC series, housed in a 14-pin SOIC package. It operates on a supply voltage (VCC) ranging from 2V to 6V. The device features a maximum propagation delay of 7.5ns at 5V and supports high-level output currents up to -24mA and low-level output currents up to 24mA. It functions within an operating free-air temperature range of -40°C to 85°C.
Feature Summary
- Performs Boolean OR logic function Y = A + B for four independent channels
- Operates across a wide supply voltage range from 2V to 6V
- Inputs accept voltages up to 6V regardless of VCC level
Applications
- Digital logic signal processing
- Boolean logic implementation in electronic circuits
- General-purpose digital systems requiring OR functionality
Procurement Notes
Verify the specific ordering suffix 'DR' corresponds to the SOIC-14 package with tape-and-reel packaging containing 2500 units. Confirm RoHS compliance and lead finish details via the manufacturer's official Package Option Addendum. Ensure the procurement matches the active production status listed for this specific part number variant.
Selection Notes
Select the SN74AC32DR when a surface-mount quadruple 2-input OR gate is required. It is suitable for designs needing operation between 2V and 6V with propagation delays under 9ns at 5V. Consider the 14-SOIC footprint for PCB layout compatibility. Verify that the input voltage tolerance up to 6V meets system requirements.
Part Context
This component belongs to the SNx4AC32 family of quadruple 2-input positive-OR gates manufactured by Texas Instruments. The AC series offers higher speed and wider voltage operation compared to older standards. The 'D' suffix indicates the Small Outline Integrated Circuit (SOIC) package type, while 'R' denotes tape-and-reel packaging for automated assembly.
Replacement Considerations
SN74AC32DBR (SSOP package), SN74AC32NSR (SOP package), SN74AC32PWR (TSSOP package). These variants share identical electrical specifications but differ in physical package dimensions.
