Description and Introduction

High Speed CMOS Logic Digital Phase-Locked-Loop The CD74HCT297E is a high-speed CMOS digital phase-locked loop (PLL) integrated circuit manufactured by Harris Semiconductor. Key specifications include:

1. **Technology**: High-Speed CMOS (HCT)  
2. **Supply Voltage Range**: 4.5V to 5.5V  
3. **Operating Temperature Range**: -55°C to +125°C  
4. **Package**: 16-pin DIP (Dual In-line Package)  
5. **Logic Family**: HCT (compatible with TTL levels)  
6. **Frequency Range**: Up to 20 MHz  
7. **Low Power Consumption**: Typical ICC of 80 µA  
8. **Input Compatibility**: TTL and CMOS  
9. **Output Drive Capability**: Standard CMOS outputs  

The CD74HCT297E is designed for applications requiring precise frequency and phase control, such as clock synchronization and signal conditioning.  

(Note: Harris Semiconductor was acquired by Intersil, which was later acquired by Renesas Electronics. The part may no longer be in production.)
