SN74F244NSR TI Buffer/Line Driver | 20-SO | 8-Ch, Non-Inverting, 4.5V-5.5V

Product Overview

The SN74F244NSR is a high-performance octal buffer and line driver designed by Texas Instruments (TI) to drive bus lines or buffer memory address registers. This device features eight non-inverting buffers with three-state outputs, organized as two 4-bit sections with separate output-enable (OE) inputs. Housed in a 20-pin SO package, it operates over a supply voltage range of 4.5V to 5.5V, making it ideal for 5V logic systems. The SN74F244NSR offers high drive capability (up to 64mA sink/32mA source) and fast propagation delays (typical 4.5ns), ensuring robust performance in high-speed digital applications.
