MC14553B Datasheet 3-Digit BCD Counter

Manufacturer: Motorola Semiconductor (now NXP Semiconductors)

Overview

www.DataSheet4U.com 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.

Key Features

  • ut of each of the three BCD counters permits storage of any given count. The three sets of BCD outputs (active high), after going through the latches, are time division multiplexed, providing one BCD number or digit at a time. Digit select outputs (active low) are provided for display control. All outputs are TTL compatible. An on.
  • chip oscillator provides the low frequency scanning clock which drives the multiplexer output selector. The frequency of the oscillator can be controlled exter.
