PI74LCX241
Fast CMOS 3.3V 8-Bit
Buffer/Line Driver
Product Features
ProductDescription
FunctionallycompatiblewithFCT3,LVT,and
74 series 241 families of products
Pericom Semiconductors PI74LCX series of logic circuits are
produced using the Companys advanced 0.6 micron CMOS
technology achieving high speed while maintaining low power
operation.
Tri-State outputs
5V Tolerant inputs and outputs
2.0V-3.6V VCC supply operation
Balanced sink and source output drives (24 mA)
Low ground bounce outputs
Supports live insertion
ThePI74LCX241isan8-bitbuffer/linedriverdesignedfor driving
high capacitive memory loads. With its balanced-drive
characteristics, this high-speed, low power device provides lower
ground bounce, transmission line matching of signals, fewer line
reflections and lower EMI and RFI effects. This makes it ideal for
driving on-board buses and transmission lines.
ESD Protection exceeds 2000V, Human Body Model
200V, Machine Model
The PI74LCX241 can be driven from either 3.3V or 5.0V devices
allowing this device to be used as a translator in a mixed
3.3V/5.0Vsystem.
