SEMICONDUCTOR TECHNICAL DATA
12-Stage Binary Ripple
Counter
High–Performance Silicon–Gate CMOS
The MC54/74C4040A is identical in pinout to the standard CMOS
MC14040. The device inputs are compatible with standard CMOS out-
puts; with pullup resistors, they are compatible with LSTTL outputs.
This device consists of 12 master–slave flip–flops. 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 counter advances on the negative–going
edge of the Clock input. Reset is asynchronous and active–high.
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 the Clock of the
HC4040A for some designs.
• Output Drive Capability: 10 LSTTL Loads
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2 to 6 V
• Low Input Current: 1 µA
• High Noise Immunity Characteristic of CMOS Devices
• In Compliance With JEDEC Standard No. 7A Requirements
• Chip Complexity: 398 FETs or 99.5 Equivalent Gates
