Overview
The SN74ACT32PW is a quad 2-input positive-OR gate from the Texas Instruments 74ACT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and features four independent logic circuits, each with two inputs. The device provides low-level output current of 24 mA and high-level output current of -24 mA. Propagation delay is typically 10 ns. It functions in an ambient temperature range from -40 °C to +85 °C and utilizes a TSSOP-14 surface-mount package.
Feature Summary
- Contains four independent 2-input OR gates for complex logic implementation
- Provides high drive capability with 24 mA output current
- Ensures fast switching performance with 10 ns propagation delay
- Compatible with standard TTL input levels
Applications
- Digital signal processing systems requiring logical OR operations
- Microcontroller-based embedded control units
- Industrial automation logic interfaces
- Consumer electronics circuit protection and signaling
Procurement Notes
Verify the specific suffix 'PW' corresponds to the TSSOP-14 package variant when sourcing. Confirm RoHS compliance status as required by project specifications. Ensure the operating environment remains within the specified -40 °C to +85 °C temperature range to maintain guaranteed electrical characteristics. Cross-reference datasheet revisions to ensure compatibility with existing design constraints.
Selection Notes
Select this component for designs requiring multiple OR gates in a compact surface-mount form factor. The ACT series offers faster switching speeds compared to standard HC counterparts while maintaining CMOS power efficiency. Verify that the 4.5 V to 5.5 V supply voltage aligns with the system's power rails. Consider the TSSOP-14 footprint availability during PCB layout planning.
Part Context
This part belongs to the SN74ACT series, which bridges the performance gap between older LS logic and newer advanced technologies. It serves as a direct pin-compatible replacement for legacy 74LS32 designs in many applications, offering improved speed without significant power penalty. The quad configuration allows for efficient space utilization in dense digital circuits.
Replacement Considerations
SN74ACT32DRG4: SOIC-14 package variant with identical electrical characteristics. SN74ACT32PWR: TSSOP-14 package variant with identical electrical characteristics.
