MC14553BCP DIP IC

5.00 د.إ

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.
