14553B, MC14553B

MC14553B 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
