ON Semiconductor MC74VHC244DTR2 Octal Buffer/Line Driver

The MC74VHC244DTR2 from ON Semiconductor is a high-performance, octal buffer and line driver designed to interface with 3.3V and 5V systems. This integrated circuit is a member of the VHC family, which is well-known for its high-speed operation while maintaining low power consumption. The MC74VHC244DTR2 is particularly suitable for driving bus lines or buffer memory address registers due to its robust output drive capability and high immunity to noise.

Constructed with silicon gate CMOS technology, this device has the ability to strengthen signal integrity by buffering the high-capacitance loads while providing a non-inverting interface. The eight buffers are organized as two sets of four, with each section having a separate 3-state output enable control. This feature allows for independent control of each section and makes the device versatile for a variety of applications.

The MC74VHC244DTR2 operates over a broad voltage range from 2V to 5.5V, and it features inputs and outputs that are high-speed, non-inverting, and have bus-hold. The bus-hold feature retains the inputs' last state whenever the input goes to a high impedance, which helps to prevent floating inputs and reduces the need for external pull-up or pull-down resistors.
