MC14553B
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.

BLOCK DIAGRAM
This device contains protection circuitry to
guard against damage due to high static
voltages or electric fields. However, pre-
cautions must be taken to avoid applications of
any voltage higher than maximum rated volt-
ages to this high–impedance circuit. For proper
operation, Vin and Vout should be constrained
to the range VSS
(Vin or Vout)
Unused inputs must always be tied to an
appropriate logic voltage level (e.g., either VSS
or VDD). Unused outputs must be left open.
