74ACTQ240QSCX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACTQ240QSCX is an octal buffer and line driver featuring inverting 3-STATE outputs. It utilizes Quiet Series technology to reduce simultaneous switching noise and improve dynamic threshold performance. The device operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature from -40°C to +85°C. Propagation delays are guaranteed at 7.5 ns maximum (5.0V, CL=50pF) with output-to-output skew limited to 1.0 ns. Outputs source and sink 24mA.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific MQA20 package designation corresponding to the Quarter Size Outline Package when sourcing this component. Confirm that the ordering suffix 'X' indicates tape and reel packaging availability as specified in the manufacturer documentation. Ensure compatibility with the required 4.5V to 5.5V supply voltage constraints during procurement planning.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high-density PCB layouts with strict simultaneous switching noise limitations. The ACTQ series offers faster propagation delays compared to standard ACT devices while maintaining TTL-compatible input thresholds. Consider the 20-lead QSOP package dimensions if space-constrained surface mount solutions are necessary for the design.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ACQ/ACTQ Quiet Series family of octal buffers and line drivers. It shares functional similarities with the 74ACQ240 and 74ACT244 but distinguishes itself through enhanced noise reduction features and guaranteed pin-to-pin skew performance provided by the underlying Quiet Series technology.
