The TC4520BF is a CMOS Dual Binary Up Counter manufactured by Toshiba Semiconductor and Storage. This integrated circuit contains two independent 4-stage binary up counters within a single package. Each counter increments its output on the rising edge of its clock input. These counters find application in diverse areas, including frequency dividers, timers, and control circuits requiring binary counting operations.

Applications

• Frequency Dividers: Used to divide an input frequency by a power of 2.
• Timers: Measuring time intervals in timing circuits.
• Control Circuits: Implementing sequential control logic.
• Event Counters: Counting the number of occurrences of an event.
• Digital Systems: Employed in various digital systems for counting and sequencing operations.

Features

• Dual Binary Up Counters: Contains two independent 4-stage binary up counters.
• CMOS Technology: Offers low power consumption and high noise immunity.
• Wide Operating Voltage Range: Typically operates from 3V to 18V.
• Synchronous Counting: Counters increment synchronously with the clock input.
• Reset Input: Each counter has a reset input for clearing the count.

Benefits

• Reduced Component Count: Simplifies circuit design by integrating two counters in one IC.
• Low Power Consumption: Suitable for battery-powered and energy-efficient applications.
• Accurate Counting: Provides accurate and reliable binary counting.
• Versatile Application: Applicable in a wide range of counting and timing scenarios.
• Reliable Performance: Offers consistent and dependable operation under varying conditions.

Additional Details

The TC4520BF typically comes in a 16-pin SOP (Small Outline Package). Each counter includes a clock input (CK), a reset input (RST), and four binary outputs (QA, QB, QC, QD). The counter increments on the rising edge of the clock signal. A high level on the reset input resets the counter to zero. The operating temperature range typically spans from -40°C to +85°C. The maximum clock frequency depends on the supply voltage and operating conditions. The outputs are designed to drive standard CMOS and TTL logic levels.
