SN74HCT244DWR Description

Short technical summary and product information.

The SN74HCT244DWR is an eight-channel buffer and line driver designed for improved performance and density in bus-oriented systems. It operates with a supply voltage range of 4.5V to 5.5V and features TTL-compatible CMOS inputs.

 

This device is organized as two independent 4-bit buffers with separate output-enable controls. When the output enable is low, data passes non-inverted from the A inputs to the Y outputs. When the output enable is high, the outputs are in a high-impedance state. The SN74HCT244DWR offers high-current outputs capable of driving up to 15 LSTTL loads and has a typical propagation delay of 13 ns.

 

Packaged in a 20-SOIC surface mount configuration, this component is suitable for various digital interface applications requiring efficient buffering and bus driving capabilities. It operates within a temperature range of -40°C to 85°C.
