ON DM7490AN

二进制计数器，十进制14.75 V ~ 5.25 V

Overview

The DM7490AN is a 4-bit synchronous decade counter with asynchronous reset. It can count in the BCD (Binary-Coded Decimal) sequence, which means it can count from 0 to 9 and then reset to 0. It is designed for various digital counting and sequencing applications. For more details about this decade counter circuit diagram, check the DM7490AN datasheet.

Available in a 14-pin DIP (Dual In-line Package)
