General Description
The 74FR16245 contains sixteen non-inverting bidirectional buffers with 3-STATE Outputs and is intended for busoriented 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
■ Non-inverting buffers
■ Bidirectional data paths
■ A and B output sink capability of 64 mA, source capability of 15 mA
■ Separate control pins for each byte
■ Guaranteed pin-to-pin skew
■ Low 3-STATE IIL
■ 16-Bit version of the 74F245 or 74F645
