Description
Pericom Semiconductor’s PI74FCT244T/541T and P174FCT2244/
2541T are 8-bit wide driver circuits, designed to be used in
applications requiring high-speed and high-output drive. Ideal
applications would include bus drivers, memory drivers, address
drivers, and system clock drivers.
The PI74FCT541 and 2541T provide similar driver capabilities,
but have their pins physically grouped by function. All inputs are
located on one side of the package, while outputs are on the opposite
side, allowing for a much simpler and denser board layout.
All PI74FCT2XXX devices have a built-in 25Ω series resistor on
all outputs to reduce noise because of refl ections, thus eliminating
the need for an external terminating resistor.
