CD4518BE two / decimal addition counter

The CD4518BE is a dual BCD (Binary-Coded Decimal) up-counter that consists of two independent 4-bit BCD counters, each having a clock input (CLOCK), a clock inhibit (INHIBIT), an asynchronous parallel load (LOAD), and asynchronous master reset (RESET). The CD4518BE is part of the CD4000 series of CMOS logic devices and is typically used in applications requiring digital counting or time measurement.
