SN74HCT244DBR Description

Short technical summary and product information.

The SN74HCT244DBR from Texas Instruments is an active octal buffer and line driver designed for improved performance and density in bus-oriented systems. This device features eight non-inverting buffer channels, each with separate output-enable (OE) inputs. When OE is low, data passes from the A inputs to the Y outputs; when OE is high, the outputs enter a high-impedance state.

 

Key electrical characteristics include a wide operating voltage range of 4.5V to 5.5V, TTL-compatible CMOS inputs, and 3-state outputs. It offers high-current outputs capable of driving up to 15 LSTTL loads and low power consumption with a maximum supply current of 80µA. The device has a typical propagation delay and low input current.

 

Packaged in a 20-SSOP, the SN74HCT244DBR is suitable for surface mounting. Its design is optimized for applications such as memory address drivers, clock drivers, and bus-oriented receivers and transmitters, improving both system performance and density.
