SN74HC244DWRG4 Description

Short technical summary and product information.

The SN74HC244DWRG4 is an octal buffer and line driver designed by Texas Instruments. It features two 4-bit buffers with separate output-enable (OE) inputs, providing non-inverted data transfer when OE is low and high-impedance outputs when OE is high. This device is suitable for improving performance and density in 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters.

 

Key electrical specifications include a wide operating voltage range of 2V to 6V, a typical propagation delay of 11ns, and low power consumption with a maximum ICC of 80µA. The outputs can drive up to 15 LSTTL loads and offer ±6mA of output drive at 5V. The input current is a maximum of 1µA.

 

This component is available in a 20-SOIC surface mount package with a body size of 12.8mm x 7.5mm. The operating temperature range is -40°C to 85°C.

 

Applications for the SN74HC244 include servers, LED displays, network switches, telecom infrastructure, motor drivers, and I/O expanders.
