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 transmit-
ter/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 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
