MC14553BCP

The MC14553BCP is a 3-digit BCD counter from the 4000 series CMOS logic family, designed for display driving applications. It features three 4-bit binary-coded decimal (BCD) counters, multiplexed outputs, and a built-in latch for stable display updates.
Key features:
- Multiplexed BCD outputs (reduces pin count)
- Internal latch for holding display data
- Cascadable for higher-digit counters
- Low power consumption (typical of CMOS)
- Wide supply voltage range (3V–18V)
Commonly used in digital clocks, counters, and instrumentation panels, it drives 7-segment displays via an external decoder (e.g., CD4511). The multiplexing frequency is set by an external clock, reducing flicker.
Package: 16-pin DIP (MC14553BCP).
A simple, cost-effective solution for 3-digit counting and display applications.

The MC14553BCP is a 3-digit BCD counter. Equivalent or similar chips include:

The MC14553BCP is a 3-digit BCD counter IC from Motorola. It comes in a 16-pin DIP (Dual In-line Package). The package type is PDIP (Plastic Dual In-line Package), which is a through-hole mounting style. It is commonly used in digital display applications like counters and clocks. The "BCP" suffix indicates the commercial temperature range (0°C to +70°C).
