74ACT16245
16-Bit Transceiver with 3-STATE Outputs
General Description
The ACT16245 contains sixteen non-inverting bidirectional
buffers with 3-STATE outputs and is intended for bus ori-
ented applications. The device is byte controlled. Each has
separate control inputs which can be shorted together for
full 16-bit operation. The T/R inputs determine the direction
of data flow through the device. The OE inputs disable both
the A and B ports by placing them in a high impedance
state.
