Description and Introduction

High Speed CMOS Logic Dual 4 -Stage Binary Counter The CD74HC393M is a dual 4-bit binary ripple counter manufactured by Texas Instruments (formerly National Semiconductor, NS). Here are its key specifications:

- **Logic Family**: HC (High-Speed CMOS)
- **Supply Voltage Range**: 2V to 6V
- **Operating Temperature Range**: -55°C to +125°C
- **Package**: SOIC-14
- **Propagation Delay**: 15 ns (typical at 5V)
- **Maximum Clock Frequency**: 50 MHz (at 5V)
- **Output Current**: ±5.2 mA (at 5V)
- **Input Capacitance**: 3.5 pF (typical)
- **Power Dissipation**: 500 mW (max)

The device features two independent counters, each with a clear function and ripple clock input. It is commonly used in frequency division and counting applications. 

(Note: Texas Instruments acquired National Semiconductor in 2011, so the part may now be listed under TI.)
