The onsemi MM74C90N is a 4-bit binary coded decimal (BCD) decade counter from the 74C series. This monolithic silicon CMOS integrated circuit features a negative edge-triggered J-K flip-flop configuration for counting. It offers independent J-K flip-flops for the decade count and the binary count. The device operates with a supply voltage range of 3V to 15V and a maximum count rate of 5 MHz. Designed for through-hole mounting, it is supplied in a 14-MDIP package. The MM74C90N is suitable for applications in industrial control, consumer electronics, and signal processing where reliable decade counting is required. It functions across an operating temperature range of -55°C to 125°C.
