Nexperia 74HC244D Octal Buffer/Line Driver, SOIC-20

The Nexperia 74HC244D is a high-speed octal buffer/line driver with 3-state outputs, supplied in a 20-pin SOIC package. This versatile device can be configured as two 4-bit buffers or one 8-bit buffer, making it ideal for bus-oriented systems requiring signal buffering and line driving. It features two output enable inputs, each controlling four of the 3-state outputs; a HIGH on the enable causes the outputs to assume a high-impedance OFF state, allowing multiple devices to share a common bus.

Inputs include clamp diodes that permit the use of current-limiting resistors to interface with input voltages in excess of VCC, enhancing design flexibility. The device operates across a supply voltage range from 2V to 6V and an ambient temperature range from -40°C to 125°C, ensuring reliable performance in demanding environments. It complies with JEDEC standard JESD 7A and features ESD protection for robust operation.

This buffer/line driver is designed for non-inverting 3-state outputs and is suitable for a wide range of digital logic applications, including memory address driving, clock driving, and general-purpose bus interfacing. With its high-speed CMOS technology, it delivers low power consumption and high noise immunity, making it a dependable choice for modern electronic designs.
