The HD74HC393FP is a high-speed CMOS dual 4-stage binary counter manufactured by Hitachi, Ltd. (now Renesas Electronics). It consists of two independent 4-stage binary counters in a single package. Each counter has an independent clock and reset input, providing versatility in counting applications.

Applications:

• Frequency dividers
• Timers
• Counters
• Digital clocks
• Control circuits
• Sequencers

Features:

• Dual 4-stage binary counters: Contains two independent counters in a single package.
• High-speed operation: Fast switching speeds due to CMOS technology.
• Independent clock and reset inputs: Provides flexibility in counting and control.
• Wide operating voltage range: Operates with a variety of power supply voltages.
• Low power consumption: CMOS technology minimizes power dissipation.
• Fanout (over standard TTL): Drives multiple loads.

Benefits:

• Reduced component count: Dual counters in one package reduce the number of components on the PCB.
• High-speed performance: Suitable for high-frequency applications.
• Versatile applications: Can be used in a wide range of counting and timing circuits.
• Simplified circuit design: Independent control inputs simplify circuit design and implementation.
• Low power consumption: Extends battery life in portable devices.

Additional Details:

The HD74HC393FP counts in binary sequence. Each section can be cascaded to create an 8-bit counter. It features a clear input that resets the counter to zero. It is available in a surface-mount package suitable for automated assembly. Operating temperature range and power dissipation are key specifications for ensuring proper operation.
