M74HC244RM13TR

Overview

The M74HC244RM13TR is an octal bus buffer with three-state outputs, manufactured by STMicroelectronics using silicon gate C2MOS technology. It operates within a supply voltage range of 2V to 6V and features balanced propagation delays. The device includes two control inputs (G) that govern four bus buffers each. It provides high noise immunity and symmetrical output impedance. The component is housed in a 20-pin SOIC package.

Feature Summary

• Octal bus buffer design with non-inverted logic
• Three-state outputs for efficient bus line driving
• High noise immunity with defined input thresholds
• Balanced propagation delays for signal integrity

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented transceivers
