All Rights Reserved 12172012 Specification Number 74FR16245-CI(F) Rev A Page 1 of 5 © 1999 Fairchild Semiconductor Corporation DS010614 www.fairchildsemi.com 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/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 Ordering Code: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
