MOTOROLA
SEMICONDUCTOR TECHNICAL DATA
Binary Counter
The MC10154 is a four–bit counter capable of divide–by–two, divide–by–
four, divide–by–eight or a divide–by–sixteen function.
Clock inputs trigger on the positive going edge of the clock pulse. Set and
Reset inputs override the clock, allowing asynchronous “set” or “clear.”
Individual Set and common Reset inputs are provided, as well as complemen–
tary outputs for the first and fourth bits. True outputs are available at all bits.
PD = 370 mW typ/pkg (No Load)
ftoggle = 150 MHz (typ)
tpd = 3.5 ns typ (C to Q0)
tpd = 11 ns typ (C to Q3)
