74FR9240
9-Bit Buffer/Line Driver with 3-STATE Outputs
General Description
The 74FR9240 is an inverting 9-bit buffer and line driver
designed to be employed as memory and address driver,
clock driver and bus oriented transmitter or receiver.
Features
s 3-STATE outputs drive bus lines or buffer memory
address registers
s Outputs sink 64 mA and source 15 mA
s Guaranteed multiple output switching, 250 pF delay and
pin-to-pin skew
s Guaranteed 4000V minimum ESD protection
s 9-bit architecture for systems carrying parity
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter โ€œXโ€ to the ordering code.
