74FCT244SCX

Buffers, Drivers, Receivers, Transceivers Overview

The National Semiconductor 74FCT244SCX is an octal buffer and line driver belonging to the FCT logic family. It features eight non-inverting buffers with three-state outputs, organized into two groups of four controlled by separate active-low output enable inputs. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical parameters include a high-level output current of -15 mA and a low-level output current of 12 mA. It functions reliably across an operating temperature range from -40°C to +85°C and utilizes a 20-lead Small Outline (SOIC) surface-mount package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific manufacturer origin as National Semiconductor assets were acquired by Texas Instruments. Confirm the part status regarding availability or obsolescence through official distributor channels. Ensure the SOIC package variant matches the required PCB footprint and verify RoHS compliance documentation before finalizing procurement decisions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal non-inverting buffer with three-state control is required for 5V logic systems. The FCT series offers speed comparable to Schottky TTL with lower power consumption. Consider the package constraints of the 20-lead SOIC form factor during layout planning and ensure adequate thermal management for the specified operating temperature range.

Buffers, Drivers, Receivers, Transceivers Part Context
