SN74ACT08BQAR

Overview

The SN74ACT08BQAR is a quadruple 2-input positive-AND gate from Texas Instruments, part of the ACT logic series. It operates within a supply voltage range of 4.5 V to 5.5 V and features a propagation delay of 10 ns. The device provides a low-level output current of 24 mA and a high-level output current of -24 mA. It is housed in a 14-WQFN (3x2.5) package.

Feature Summary

• Contains four independent 2-input AND gates for complex logic implementation
• High-speed performance with 10 ns propagation delay
• Robust output drive capability with 24 mA sink and source currents

Applications

• High-speed digital logic systems
• Data acquisition circuits
• Telecommunications equipment

Procurement Notes

Verify the specific suffix BQAR corresponds to the 14-WQFN (3x2.5) package configuration. Confirm that the operating temperature range aligns with system requirements, as automotive variants may differ. Ensure ESD protection measures are adequate during handling due to CMOS sensitivity.

Selection Notes

Select this component when high-speed switching is required alongside standard TTL-compatible input levels. Compare against SN74AC08 for wider voltage ranges or SN74AS08 for faster speeds. Verify pinout compatibility if replacing legacy DIP packages with surface-mount designs.

Part Context

This part belongs to the SN74ACT family, which combines AC speed with ACT input characteristics. It serves as a fundamental building block for sequential and combinational logic circuits requiring precise timing and reliable signal processing in industrial applications.

Replacement Considerations

SN74ACT08PWRQ1 offers similar electrical characteristics but utilizes a TSSOP-14 package instead of WQFN.
