Overview
The SN74AC32DBR is a quadruple 2-input positive-OR gate manufactured by Texas Instruments in the AC logic family. It operates on a supply voltage range of 2V to 6V and features inputs that accept voltages up to 6V. The device provides a maximum propagation delay of 7.5ns at 5V. It is housed in a 14-pin SSOP package with dimensions of 6.2mm x 7.8mm. The recommended operating temperature range extends from -40°C to 85°C.
Feature Summary
- Performs Boolean OR function Y = A + B
- Operates within 2V to 6V supply range
- Inputs tolerate voltages up to 6V
- High-speed switching capability
Applications
- Digital logic signal processing
- Boolean function implementation
- Positive logic circuit design
Procurement Notes
Verify the specific ordering suffix 'DBR' corresponds to the SSOP package and tape-and-reel carrier format. Confirm RoHS compliance status and moisture sensitivity level ratings prior to procurement. Ensure the selected variant matches the required operating temperature range for the intended application environment.
Selection Notes
Select this component when a quadruple 2-input OR gate is required with high-speed performance. The AC series offers faster switching speeds compared to standard HC or HCT families. Verify that the 2V to 6V supply voltage range aligns with the system power rails and that the 7.5ns propagation delay meets timing requirements.
Part Context
This part belongs to the SNx4AC32 family of quadruple 2-input positive-OR gates. The AC series represents a high-speed CMOS technology. The DBR suffix specifically denotes the SSOP package type with reel packaging, distinguishing it from other package options like SOIC or PDIP available within the same logical family.
