SEMICONDUCTOR TECHNICAL DATA
14-Stage Binary Ripple
Counter With Oscillator
High–Performance Silicon–Gate CMOS
The MC54/74C4060A is identical in pinout to the standard CMOS
MC14060B. The device inputs are compatible with standard CMOS out-
puts; with pullup resistors, they are compatible with LSTTL outputs.
This device consists of 14 master–slave flip–flops and an oscillator
with a frequency that is controlled either by a crystal or by an RC circuit
connected externally. The output of each flip–flop feeds the next and the
frequency at each output is half of that of the preceding one. The state of
the counter advances on the negative–going edge of the Osc In. The
active–high Reset is asynchronous and disables the oscillator to allow
very low power consumption during stand–by operation.
State changes of the Q outputs do not occur simultaneously because
of internal ripple delays. Therefore, decoded output signals are subject to
decoding spikes and may have to be gated with Osc Out 2 of the
HC4060A.
Output Drive Capability: 10 LSTTL Loads
