74ABT16245 General Description
The ABT16245 contains sixteen non-inverting bidirectional buffers with 3-STATE outputs and is intended for bus oriented applications. The device is byte controlled. Each byte 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.
