Description
74FR16541 16-Bit Buffer/Line Driver with 3-STATE Outputs October 1989 Revised August 1999 74FR16541 16-Bit Buffer/Line Driver with 3-STATE Outputs General Description The 74FR16541 contains sixteen non-inverting buffers with 3-STATE outputs designed to be employed as a memory and address driver, clock driver, or bus-oriented transmitter/receiver.
More View 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 Non-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 multiple output switching, 250 pF delays and pin-to-pin skew s 16-bit version of the 74F541, 74F244 or 74FR244 Ordering Code: Order Number 74FR16541QC 74FR16541SSC 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. Specify by appending the suffix letter “X” to the ordering code.
