SN74HC244DBR Description

Short technical summary and product information.

The SN74HC244DBR 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 an output-enable (OE) input. When OE is low, data passes from the A inputs to the Y outputs; when OE is high, the outputs are in a high-impedance state.

 

Key electrical characteristics include a wide operating voltage range of 2 V to 6 V, a typical propagation delay of 11 ns, and ±6 mA output drive at 5 V. It offers low power consumption with a maximum ICC of 80 µA and low input current of 1 µA. The SN74HC244DBR is supplied in a 20-SSOP package suitable for surface mounting.

 

Applications for this buffer include servers, LED displays, network switches, telecom infrastructure, motor drivers, and I/O expanders. Its 3-state outputs are ideal for driving bus lines or buffering memory address registers.
