The 74VHCT244ATTR is an advanced high-speed CMOS octal bus buffer with 3-state outputs, manufactured by STMicroelectronics. It is designed for applications requiring efficient data buffering and is compatible with TTL outputs. This device features a wide operating voltage range from 4.5V to 5.5V and operates across a broad temperature range of -55°C to 125°C.
Key electrical characteristics include a low propagation delay of 5.4 ns (typical) at 5V and a low supply current of 4 μA (maximum) at 25°C. The buffer provides symmetrical output impedance with |IOH| = IOL = 8 mA (minimum). It also offers power-down protection on inputs and outputs, and 2KV ESD immunity.
The 74VHCT244ATTR is supplied in a 20-SOIC package, suitable for surface mount applications. Its pin and function are compatible with the 74 Series 244, making it an easy drop-in replacement in many designs. The device is designed to interface 5V to 3V systems due to its TTL threshold inputs.
