The MC14553B 3digit 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 onchip oscillator provides the lowfrequency 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.
