The TC74VHC393AF is a high-speed CMOS Dual 4-Bit Binary Counter manufactured by Toshiba Semiconductor and Storage. This device incorporates two independent 4-bit binary counters in a single package. The VHC family offers high-speed performance with low power dissipation. This counter is ideal for frequency division, timing, and control applications.

Applications

• Frequency division
• Timing circuits
• Address generation
• Sequence generation
• Digital system control

Features

• Dual 4-bit binary counters
• High-speed operation: fMAX = 125 MHz (typ.) at VCC = 5 V
• Low power dissipation: ICC = 4 μA (max.) at Ta = 25 °C
• Wide operating voltage range: VCC = 2 V to 5.5 V
• Asynchronous clear inputs for each counter
• Carry output for cascading counters
• Available in SOP14 package

Benefits

• Precise timing control with synchronous operation
• Improved system performance due to high-speed operation
• Reduced power consumption, leading to energy efficiency
• Flexible integration into various systems with a wide operating voltage range
• Easy cascading for higher count ranges
• Compact design facilitated by the SOP14 package

Additional Details

The TC74VHC393AF consists of two independent 4-bit binary counters, each with an asynchronous clear input. The counters increment on the negative edge of the clock input. The carry output (CO) is high when the counter reaches a count of 15. The clear input resets the counter to zero regardless of the clock input. This device is well-suited for applications requiring multiple counters or frequency division.
