74FR9245 9-Bit Bidirectional Transceiver with 3-STATE Outputs April 1991 Revised August 1999 74FR9245 9-Bit Bidirectional Transceiver with 3-STATE Outputs General Description The 74FR9245 contains nine non-inverting bidirectional buffers with 3-STATE outputs and is intended for bus-oriented applications. Current sinking capability is 64 m A on both the A and B Ports. The Transmit/Receive (T/R) input determines the direction of data flow through the bidirectional transceiver. Transmit (active-HIGH) enables data from A Ports to B Ports; Receive (active-LOW) enables data from B Ports to A Ports. The Output Enable input, when HIGH, disables both A and B Ports by placing them in a High Z condition. Features s Non-inverting buffers s Bidirectional data path s A and B output sink capability of 64 m A, source capability of 15 m A s Guaranteed pin-to-pin skew, multiple output switching and 250 pf delay Ordering Code: Order Number 74FR9245SC 74FR9245MSA 74FR9245SPC Package Number M24B MSA24 N24C Package Description 24-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300 Wide 24-Lead Shrink Small Outline Package (SSOP), EIAJ TYPE II, 5.3mm Wide 24-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-100, 0.300 Wide Devices also available in Tape and Reel.
