SN74HC244N Description

Short technical summary and product information.

The SN74HC244N is an octal buffer and line driver designed for improved performance and density in bus-oriented systems. It features two 4-bit buffers with separate output-enable inputs. When the output enable is low, data passes from the A inputs to the Y outputs; when high, the outputs are in a high-impedance state.

 

This device operates over a wide voltage range of 2V to 6V, making it versatile for various applications. It provides high-current outputs capable of driving up to 15 LSTTL loads and offers ±6mA output drive at 5V. The low power consumption, with a maximum ICC of 80µA, is beneficial for power-sensitive designs. Typical propagation delay is 11ns.

 

The SN74HC244N is suitable for applications such as servers, LED displays, network switches, telecom infrastructure, motor drivers, and I/O expanders. It is available in a 20-pin PDIP package and operates within a temperature range of -40°C to 125°C.
