The MC14553B 3–digit BCD counter consists of 3 negative edge
triggered BCD counters that are cascaded synchronously. A quad latch
at the output of each counter permits storage of any given count. The
information is then time division multiplexed, providing one BCD
number or digit at a time. Digit select outputs provide display control.
All outputs are TTL compatible.
An on–chip oscillator provides the low–frequency scanning clock
which drives the multiplexer output selector.
This device is used in instrumentation counters, clock displays,
digital panel meters, and as a building block for general logic
applications.

1. Maximum Ratings are those values beyond which damage to the device
may occur.
2. Temperature Derating:
Plastic “P and D/DW” Packages: – 7.0 mW/ C From 65 C To 125 C
This device contains protection circuitry to guard against damage due to high
static voltages or electric fields. However, precautions must be taken to avoid
applications of any voltage higher than maximum rated voltages to this
high–impedance circuit. For proper operation, V

out
should be constrained
to the range V

Unused inputs must always be tied to an appropriate logic voltage level (e.g.,
either V
SS
or V
DD
). Unused outputs must be left open.
