The TC74VHC161FS(EL) is a high-speed CMOS synchronous 4-bit binary counter manufactured by Toshiba Semiconductor and Storage. This counter features a synchronous counting operation, meaning that all flip-flops are clocked simultaneously, ensuring predictable timing characteristics. The (EL) designation typically refers to a specific tape and reel packaging option.

Applications

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

Features

• Synchronous 4-bit binary counting
• 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 input
• Carry output for cascading counters
• Available in SOP16 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 SOP16 package

Additional Details

The TC74VHC161FS(EL) is a synchronous 4-bit binary counter with an asynchronous clear input. The counter increments on the rising 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 precise counting and timing control. The (EL) suffix usually indicates tape and reel packaging for automated assembly.

Package: SOP16

Operating Temperature Range: -40°C to +85°C
