Description and Introduction

Baseband Processor for FP & PP DECT and WDCT Part Number: SC14428  
Manufacturer: NSC (National Semiconductor Corporation)  

**Specifications:**  
- **Type:** Digital IC  
- **Function:** Dual 4-Bit Binary Counter  
- **Technology:** CMOS  
- **Supply Voltage (Vcc):** 3V to 18V  
- **Operating Temperature Range:** -55°C to +125°C  
- **Package Options:** DIP (Dual In-line Package), SOIC (Small Outline IC)  

**Descriptions:**  
The SC14428 is a dual 4-bit binary counter IC designed for digital counting applications. It features two independent 4-bit counters, each with a synchronous reset function. The device is built using CMOS technology, ensuring low power consumption and high noise immunity.  

**Features:**  
- Dual 4-bit binary counters in a single package  
- Synchronous reset for each counter  
- Wide operating voltage range (3V to 18V)  
- Low power consumption (typical CMOS standby current)  
- High noise immunity  
- Compatible with TTL and CMOS logic levels  
- Available in standard DIP and SOIC packages  

(Note: The information provided is based on available historical data. For current details, verify with the manufacturer or authorized distributors.)
