SN74HC244DWR Description

Short technical summary and product information.

The SN74HC244DWR from Texas Instruments is an octal buffer and line driver designed for improved performance and density in 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. This device features two independent 4-bit buffers, each with a separate output-enable (OE) input. When OE is low, data passes non-inverted 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, high-current outputs capable of driving up to 15 LSTTL loads, and a typical propagation delay of 11 ns. The device consumes low power, with a maximum ICC of 80 µA and a low input current of 1 µA. The output drive current is specified at ±6 mA at 5V, with typical values of 7.8mA, 7.8mA.

 

Designed for surface mounting, the SN74HC244DWR comes in a 20-SOIC package with dimensions of 0.295 inches (7.50mm) width. It operates within a temperature range of -40°C to 85°C. Applications include servers, LED displays, network switches, telecom infrastructure, motor drivers, and I/O expanders.
