These buffers have Hi-Z state Output Enable inputs (active LOW) with a 1-in, 4-out configuration per group. Each clock driver consists of two banks of drivers, driving four outputs each from a standard TTL compatible CMOS input. • • • • • 3.3V version of PI49FCT804T Low output skew: 0.7ns Clock busing with Hi-Z state control TTL input and output levels, reducing problematic “ground bounce” Extremely low static power (1mW, typical) Hysteresis on all inputs ESD protection exceeds 2000V Industrial Operation: –40°C to 85°C Packaging (Pb-free & Green available): – 16-pin 300-mil wide plastic SOIC (S) Block Diagram Pin Configuration OEA 4 INA OA3-OA0 4 INB OB3-OB0 OEB 1 OA0 1 16 VCC OA1 2 15 OB0 OA2 3 OB1 GND 4 16-Pin 14 S 13 OA3 5 12 GND GND 6 11 OB3 OEA 7 10 OEB INA 8 9 INB OB2 PS7043F 09/24/04 PI49FCT3804 3.3V Buffer/Clock Driver 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 Pin Description Truth Table(1) Pin Name De s cription Inputs OEA, OEB Hi- Z State Output Enable Inputs (Active LOW) INA, INB Outputs OEA, OEB INA, INB OAN, OBN Clock Inputs L L L Clock Outputs L H H GND Ground H L Z VCC Power H H Z OAN, OBN Notes: H = High Voltage Level L = Low Voltage Level Z = High Impedance Capacitance (TA = 25°C, f = 1 MHz) Parameters(1) Description Test Conditions Typ.
