74HCT244 Description

Short technical summary and product information.

The Texas Instruments 74HCT244 is an octal buffer/line driver designed for high-speed CMOS logic applications. This device features six non-inverting buffers, each with a 3-state output, controlled by a common output enable. It is compatible with TTL logic levels due to its TTL-compatible CMOS inputs.

 

The 74HCT244 operates over a supply voltage range of 4.5V to 5.5V, making it suitable for various digital systems. It offers balanced outputs and a typical propagation delay of 8ns, ensuring efficient signal transmission. The device is available in PDIP and SOIC packages, supporting different mounting requirements.

 

Key electrical characteristics include a maximum output current (IOL) of 6mA and a maximum output current (IOH) of -6mA. The supply current is a maximum of 160µA. The operating temperature range is from -55°C to 125°C, providing robustness in diverse environmental conditions.

 

This buffer/driver is ideal for applications requiring signal buffering, line driving, or interfacing between different logic families. Its 3-state outputs allow for bus-oriented systems where multiple devices share a common data line.
