詳細說明
The HEF4526BT is a CMOS integrated circuit typically used in electronic counter applications. It features a 4-bit synchronous decade counter with an asynchronous reset. The device operates over a wide voltage range, typically from 3 to 15 volts, making it suitable for various power supply configurations. It offers high-speed operation with a clock frequency capability of up to 12 MHz. The counter advances on the rising edge of the clock signal when the enable input is high. It includes provisions for cascading multiple counters for larger counting applications. The asynchronous reset input allows the counter to be cleared to its zero state independently of the clock signal. The HEF4526BT is housed in a 16-pin dual in-line package (DIP), providing ease of integration into electronic circuits.
