Overview
The SN74AC08PWR is a Texas Instruments quadruple 2-input positive-AND gate in the 74AC logic series. It operates on a supply voltage range of 2V to 6V and supports an operating temperature from -40°C to +85°C. Key electrical parameters include a maximum propagation delay of 7.5ns at 5V, output drive currents of ±24mA, and a maximum static current of 2µA. The device utilizes a 14-TSSOP surface-mount package.
Feature Summary
- Executes Boolean AND functions with high-speed performance suitable for digital signal processing.
- Features robust output drive capability allowing direct interfacing with loads without additional buffering.
- Accepts input voltages up to 6V, providing flexibility in mixed-voltage system designs.
Applications
- Digital logic circuits requiring fast switching speeds.
- LED driving applications utilizing high output current.
- Control and automation systems.
- Replacement for line drivers in data transmission paths.
Procurement Notes
Verify the specific suffix 'PWR' corresponds to the TSSOP-14 package variant when sourcing. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments, as these are dynamic commercial factors not included in technical specifications.
Selection Notes
Select this component for designs requiring AC-series speed within a wide 2V to 6V supply range. It serves as a high-drive alternative to HC/HCT families. Ensure the application does not require automotive AEC-Q100 qualification; if required, choose the SN74AC08Q variant instead.
Part Context
This part belongs to the Texas Instruments 74AC family of high-speed CMOS logic devices. It provides superior speed and drive strength compared to standard HC series parts while maintaining compatibility with similar form factors. The SN74AC08PWR specifically denotes the plastic small-outline thin profile (TSSOP) packaging option.
Replacement Considerations
SN74AC08DR: Same logic function and electrical characteristics but housed in a 14-SOIC package rather than TSSOP. Verify pinout compatibility and thermal requirements before substituting.
FAQ
What is the maximum propagation delay for the SN74AC08PWR?
The maximum propagation delay is 7.5ns when operated at a supply voltage of 5V.
Does the SN74AC08PWR meet automotive reliability standards?
No, the standard SN74AC08PWR is a commercial-grade device. Automotive applications require the SN74AC08-Q1 series which holds AEC-Q100 certification.
