74AC16244SSCX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74AC16244SSCX is a 16-bit non-inverting buffer and line driver featuring 3-STATE outputs, housed in a 48-lead Small Shrink Outline Package (SSOP). It operates within a supply voltage range of 2.0V to 6.0V for the AC variant. The device provides separate control logic for each nibble, allowing independent or combined operation. Outputs can source and sink up to 24 mA. Propagation delays typically range from 4.3 ns to 7.0 ns at 5.0V with 50 pF load.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Contains sixteen non-inverting buffers with independent 3-STATE output control for each nibble
• Designed for use as memory drivers, address drivers, clock drivers, or bus-oriented transmitters
• Outputs capable of sourcing and sinking significant current for direct interface applications

• Memory address drivers
• Clock signal distribution
• Bus-oriented transmitter/receiver circuits

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'X' indicates tape and reel packaging when ordering. Confirm the exact voltage requirements align with the AC series specifications (2.0V–6.0V) rather than the ACT series. Ensure the SSOP package dimensions match the design footprint. Check for any lifecycle status updates from the manufacturer regarding this specific part number before finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit wide data path requires high-speed buffering with tri-state capability. The separate nibble controls offer flexibility for partial byte operations. Compare propagation delay characteristics against system timing constraints. Consider power dissipation limits if multiple outputs switch simultaneously. Verify input compatibility with the driving logic family.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the 74AC/ACT logic family, specifically the 16-bit buffer derivative of the 8-bit 74AC244. It shares functional similarities with other 16-bit bus transceivers but lacks bidirectional direction control. The SSOP package offers a compact solution for dense PCB layouts compared to wider DIP packages.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include the 74ACT16244SSCX for TTL-compatible inputs. Other 16-bit buffers like the 74AC16245 may be considered if bidirectional functionality is required instead of unidirectional buffering.
