The P6C1816 is composed of non-inverting 4 groups of 1-in to 4out driver. Each group of output has a pair of power and ground pins to minimize noise and also improve performance. Maximum Operating Frequency: 133MHz Low skew < 350ps Low propagation delay < 3.5ns Fast output rise/fall time < 1.0ns Balanced CMOS outputs Industrial Operation: -400C to +850C 3.3V supply voltage 5V tolerant input Available in 28-pin 50mil PLCC OUTD[0-3] 8 OUTB2 OUTA1 2 1 28 27 26 OUTA0 3 V DD INA 7 INB OUTA2 6 OUTB1 GND VDD 4 28-Pin J OUTD3 24 GND 23 OUTD2 22 IND 9 21 OUTD1 10 20 VDD OUTB3 11 19 OUTD0 OUTC3 GND 12 13 14 15 16 17 18 1 25 GND OUTC2 4 OUTC[0-3] 5 INC IND 4 OUTB[0-3] OUTB0 OUTC1 INC 4 OUTA[0-3] VDD INB 4 OUTC0 INA Pin Configuration OUTA3 Block Diagram PS8624 07/24/02 PI6C1816 3.3V 4x1:4 CMOS Clock Driver 1234567890123456789012345678901212345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901 1234567890123456789012345678901212345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901 1234567890123456789012345678901212345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901 Pin Description Pin Signal IN[A-D] OUTA[0-3] OUTB[0-3] OUTC[0-3] OUTD[0-3] GND VDD 1,8,15,22 26, 28, 2, 4 5, 7, 9, 11 12, 14, 16, 18 19, 21, 23, 25 3, 10, 17, 24 6, 13, 20, 27 Description Reference Clock Inputs Clock Outputs (Group A) Clock Outputs (Group B) Clock Outputs (Group C) Clock Outputs (Group D) Ground 3.3V Power Supply Maximum Ratings (Above which the useful life may be impaired.
