3-Digit BCD Counter
-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. TTL Compatible Outputs On–Chip Oscillator Cascadable Clock Disable Input Pulse Shaping Permits Very Slow Rise Times on Input Clock Output Latches Master Reset
