PI74LCX652

Fast CMOS 3.3V 8-Bit Registered Transceiver

Product Description

Product Features

• FunctionallycompatiblewithFCT3,LVT,and

74 series 646 and 652 families of products

PericomSemiconductor’sPI74LCXseriesoflogiccircuitsarepro-

duced in the Company’s advanced 0.6 micron CMOS technology,

achieving industry leading speed grades.

• 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

The PI74LCX646 and PI74LCX652 are designed with a bus

transceiver with 3-state D-type flip-flops and control circuitry

arrangedformultiplexedtransmissionofdatadirectlyfromthedata

busorfromtheinternalstorageregisters. ThePI74LCX652utilizes

GAB and GBA signals to control the transceiver functions. The

PI74LCX646 uses the enable control (G) and direction pins (DIR)

to control the transceiver functions. SAB and SBA control pins are

used to select either real-time or stored data transfer. The circuitry

occurs in a multiplexer during the transition between real-time and

stored data. A low input level selects real-time data and a high

selects stored data.
