Overview
The HEF40244BT,652 is an 8-bit buffer/line driver with 3-state outputs, manufactured by Nexperia USA Inc. This integrated circuit (IC) is part of the HEF4000B family and is designed to provide high-performance buffering capabilities. The device can be used as two 4-bit buffers or one 8-bit buffer, making it versatile for various digital logic applications. It features two output enables (1OE and 2OE), each controlling four of the 3-state outputs, which can assume a high-impedance OFF-state when the output enable is HIGH.
