SN74HCT244PWR Description

Short technical summary and product information.

The SN74HCT244PWR from Texas Instruments is an octal buffer and line driver designed for improved performance and density in bus-oriented systems. This device features eight channels organized as two 4-bit buffers, each with separate output-enable inputs. It operates within a voltage range of 4.5V to 5.5V and offers high-current outputs capable of driving up to 15 LSTTL loads.

 

The SN74HCT244PWR has TTL-compatible CMOS inputs and 3-state outputs, making it suitable for driving bus lines and buffering memory address registers. Key electrical characteristics include a low supply current of 80µA maximum and a typical propagation delay of 13ns. The component is housed in a 20-TSSOP package, designed for surface mounting.

 

With an operating temperature range of -40°C to 125°C, this buffer is suitable for various industrial applications. Its design facilitates efficient buffering of clock drivers and memory address drivers, enhancing system performance and integration.
