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 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 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 Ordering Code: Order Number 74FR16245QC 74FR16245SSC Package Number V44A MS48A Package Description 44-Lead Plastic Lead Chip Carrier (PLCC), JEDEC MO-047, 0.650 Square 48-Lead Small Shrink Outline Package (SSOP), JEDEC MO-118, 0.300 Wide Devices also available in Tape and Reel.
