MC14553 Datasheet 3-digit Bcd Counter

Manufacturer: Motorola Semiconductor (now NXP Semiconductors)

Overview: MOTOROLA SEMICONDUCTOR TECHNICAL DATA 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

  • cy scanning clock which drives the multiplexer output 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 LATCH ENABLE 10 CLOCK 12 pulse for every 1000 counts. The Master Reset input, when taken high, initializes the three BCD counters and the multiplexer scanning circuit. While Master Reset is.
