SN74F244DB TI Buffer/Line Driver | 20-SSOP | 8-Ch, Non-Inverting, 4.5V-5.5V

Product Overview

The SN74F244DB is a high-performance octal buffer and line driver designed by Texas Instruments (TI) to drive heavily loaded 5V buses. It features eight non-inverting buffers with three-state outputs, organized as two 4-bit sections with separate output enable (OE) controls. Housed in a compact 20-pin SSOP package, this device is ideal for memory address drivers, clock drivers, and bus-oriented systems requiring high drive current and fast switching speeds.

Detailed Technical Specifications

Key Features

• Eight non-inverting buffers with three-state outputs
• Two independent 4-bit sections with separate OE pins
• High drive capability: IOL = 64 mA, IOH = -15 mA
• Fast propagation delay: 4.5 ns typical
• Inputs are TTL-compatible
• Outputs source/sink 24 mA at 5V
• ESD protection exceeds 2000 V per MIL-STD-883
