Nexperia B.V. Octal buffer/line driver; 3-state 74ABT244D,623

The 74ABT244 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 and 2OE), each controlling four of the 3-state outputs. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state. This device is fully specified for partial power down applications using I_OFF. The I_OFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down.
