TI SN74LS193N

二进制计数器14.75 V ~ 5.25 V

Overview

The SN74LS193N is a TTL (Transistor-Transistor Logic) integrated circuit that functions as a 4-bit synchronous binary counter with dual clock and clear, capable of counting up or down. It is commonly used in various digital applications for counting events, frequency division, and timekeeping. This  UP/DOWN MODULO-16 binary counter utilizes distinct Count Up and Count Down Clocks, functioning synchronously in both modes. The state of the outputs changes in tandem with the LOW-to-HIGH shifts on the clock inputs. Both distinct Terminal Count Up and Terminal Count Down outputs are offered, serving as the clocks for the following stages. This setup obviates the need for additional logic, streamlining the design of multi-stage counters. For more details about this counter pinout, circuit diagram, etc can check the SN74LS193N datasheet.
