74ACT245SJX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACT245SJX is an octal bidirectional transceiver belonging to the 74ACT logic series. It features eight non-inverting buffers with three-state outputs, designed for bus-oriented applications. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input levels while providing CMOS output levels. It exhibits a propagation delay of 8 ns and delivers a low-level output current of 24 mA alongside a high-level output current of -24 mA at both A and B ports. The component is housed in a 20-pin SOP package and functions reliably across an operating temperature range from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix SJX against the manufacturer's latest documentation to confirm package dimensions and tape-and-reel specifications. Confirm RoHS compliance status directly with the supplier as regulatory details may vary by production batch. Ensure the obsolete status is accounted for in long-term design maintenance plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal width is required for parallel data transfer on a shared bus architecture. The ACT series offers faster switching speeds compared to standard AC variants while maintaining CMOS power efficiency. Verify that the SOP-20 footprint aligns with the target PCB layout constraints before finalizing the bill of materials.
