SN74HC244APWR Description

Short technical summary and product information.

The SN74HC244APWR from Texas Instruments is an octal buffer and line driver designed to enhance the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. This device features two 4-bit buffers and drivers, each with separate output-enable (OE) inputs. When OE is low, non-inverted data passes from the A inputs to the Y outputs. When OE is high, the outputs enter a high-impedance state.

 

Key electrical specifications include a wide operating voltage range of 2V to 6V and a low supply current of 80µA maximum. The outputs can drive up to 7.8mA, and the device boasts a very high speed with a typical propagation delay of 11ns. The input type is Standard CMOS, and the output type is 3-State, with features like balanced outputs and an input clamp diode.

 

Packaged in a 20-TSSOP, the SN74HC244APWR is suitable for surface mount applications. Its operating temperature range is -40°C to 125°C. This component is rated for automotive and catalog applications, making it versatile for various electronic designs.
