74ABT16245
16-Bit Transceiver with 3-STATE Outputs
General Description
The ABT16245 contains sixteen non-inverting bidirectional
buffers with 3-STATE outputs and is intended for bus ori-
ented 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.
Features
s Bidirectional non-inverting buffers
