PIN DESCRIPTIONS
INPUTS
Clock (Pins 1, 13)
Clock input. The internal flip–flops are toggled and the
counter state advances on high–to–low transitions of the
clock input.
CONTROL INPUTS
Reset (Pins 2, 12)
Active–high, asynchronous reset. A separate reset is pro-
vided for each counter. A high at the Reset input prevents
counting and forces all four outputs low.
OUTPUTS
Q1, Q2, Q3, Q4 (Pins 3, 4, 5, 6, 8, 9, 10, 11)
Parallel binary outputs Q4 is the most significant bit.
