74FR16540 16-Bit Buffer/Line Driver with 3-STATE Outputs October 1989 Revised August 1999 74FR16540 16-Bit Buffer/Line Driver with 3-STATE Outputs General Description The 74FR16540 contains sixteen inverting buffers with 3STATE outputs designed to be employed as a memory and address driver, clock driver, or bus-oriented transmitter/ receiver. The device is byte controlled. Each byte has separate 3-STATE control inputs which can be shorted together for full 16-bit operation. Features s Inverting buffers s 3-STATE outputs drive bus lines s Output sink capability of 64 mA, source capability of 15 mA s Separate 3-STATE control pins for each byte s Guaranteed 4000V minimum ESD protection s Guaranteed multiple output switching, 250 pF delays and pin-to-pin skew s 16-bit version of the 74F540, 74F240, or 74FR240 Ordering Code: Order Number 74FR16540QC 74FR16540SSC 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.
