Texas Instruments SN74LS669D is a 4-bit synchronous binary counter from the 74LS series. This monolithic integrated circuit features a 4-bit up/down counter with synchronous load capability. The SN74LS669D offers versatile counting operations, allowing for both incrementing and decrementing of binary values triggered by positive edge transitions. It includes asynchronous preset inputs for direct control over the counter's state and an asynchronous clear input. With a maximum count rate of 32 MHz and an operating voltage range of 4.75 V to 5.25 V, this component is suitable for applications in industrial automation, consumer electronics, and telecommunications equipment. The device is supplied in a 16-SOIC package designed for surface mounting.
