DM74S244N

Buffers, Drivers, Receivers, Transceivers Overview

The DM74S244N is an octal bus driver manufactured by Fairchild Semiconductor, utilizing Schottky TTL technology. It features eight non-inverting buffers with three-state outputs organized into two groups of four, each controlled by a separate active-low output enable input. The device operates within a supply voltage range of 4.5V to 5.5V and is housed in a standard 20-pin DIP package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific manufacturer origin, as Fairchild Semiconductor's logic division was acquired by onsemi. Confirm that the component matches the original Fairchild specifications rather than subsequent production runs. Ensure the package type corresponds to the required footprint and pin configuration for the target application.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed switching performance is required alongside low power dissipation relative to standard TTL. It serves as a functional replacement for older Schottky counterparts while maintaining pin compatibility. Consider the bidirectional or unidirectional buffer requirements based on the specific system architecture needs.
