74FR16245 16-Bit Transceiver with 3-STATE Outputs
October 1989
Revised August 1999
74FR16245
16-Bit Transceiver with 3-STATE Outputs
General Description
The 74FR16245 contains sixteen non-inverting bidirec-
tional buffers with 3-STATE outputs and is intended for bus-
oriented applications. Current sinking capability is 64 mA
on both the A and B Ports. The device is byte controlled.
Each byte has separate control inputs which can be
shorted together for full 16-bit operation. The transmit/
receive (T/R
n
) inputs determine the direction of data flow
through the transceiver. The output enable (OE
n
) inputs
disable both A and B Ports by placing them in an high
impedance state.
