PI74LCX16827
Fast CMOS 3.3V 20-Bit Buffers
Product Features
Product Description
• FunctionallycompatiblewithFCT3,LVT,and74series
16827 families of products
Pericom Semiconductor’s PI74LCX series of logic circuits are
producedin the Company’sadvanced0.6micronCMOStechnology,
achieving industry leading speed grades.
• Tri-State outputs
ThePI74LCX16827isa20-bitwidebusdriverdesignedtoprovide
buffering and high-performance bus interfacing for wide data/
address paths or busses with parity. Two pairs of nanded output
enable controls allow the device to be operated as two
10-bit buffers or as one 20-bit buffer. Signal pins are arranged in a
flow-through organization for ease of layout and hysteresis is
designed into all inputs to improve noise margin.
• 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
• ESD Protection exceeds 2000V, Human Body Model
200V, Machine Model
ThePI74LCX16827canbedrivenfromeither3.3Vor5.0Vdevices
allowing this device to be used as a translator in a mixed
3.3V/5.0V system.
