The TC4526BP is a CMOS Programmable Down Counter manufactured by Toshiba Semiconductor and Storage. This integrated circuit is designed to count down from a preset value to zero. The initial value is loaded into the counter via programming inputs, and the counter decrements on each clock pulse. When the counter reaches zero, an output signal is generated. It's utilized in timing applications, control systems, and frequency synthesis where precise countdown functionality is needed.

Additional Details
The TC4526BP typically comes in a 16-pin DIP (Dual In-Line Package). It features a clock input (CK), programming inputs for setting the initial count, a zero detect output (Z), and a reset input (RST). The initial count is loaded into the counter via the programming inputs. The counter decrements on the rising edge of the clock signal. When the counter reaches zero, the Z output goes high. The RST input resets the counter to its initial value. The operating temperature range is typically -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.
