Manufacturer: onsemi

Overview: MC14553B 3-Digit BCD Counter The MC14553B 3–digit BCD counter consists of 3 negative edge triggered BCD counters that are cascaded synchronously.

Key Features

  • selector. The frequency of the oscillator can be controlled externally by a capacitor between pins 3 and 4, or it can be overridden and driven with an external clock at pin 4. Multiple devices can be cascaded using the overflow output, which provides one pulse for every 1000 counts. LATCH ENABLE 10 CLOCK 12 The Master Reset input, when taken high, initializes the three BCD counters and the multiplexer scanning circuit. While Master Reset is high the digit scanner is set to digit one; but all t.
