General Description
The ’ABT16245 contains sixteen non-inverting bidirectional
buffers with TRI-STATE outputs and is intended for bus
oriented applications. The device is byte controlled. Each
byte has separate control inputs which can be shorted to-
gether 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.
