NXP 74HC Series Logic Devices
- NXP 74HC244D, 652, The 74HCT244D is an 8-bit buffer/line driver with 3-state outputs. The device can be used as two 4-bit buffers or one 8-bit buffer. The device features two output enables (1OE & 2OE), each controlling four of the 3-state outputs. A HIGH on n OE causes the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC.
