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/Rn) inputs determine the direction of data flow
through the transceiver. The output enable (OEn) inputs
disable both A and B Ports by placing them in an high
impedance state.
Features
s Non-inverting buffers
s Bidirectional data paths
s A and B output sink capability of 64 mA, source
capability of 15 mA
s Separate control pins for each byte
s Guaranteed pin-to-pin skew
s Low 3-STATE IIL
s 16-Bit version of the 74F245 or 74F645
