SN54LS693J TI Counter/Divider | 4-Bit Binary, Synchronous, Presettable

Product Overview

The SN54LS693J is a high-performance 4-bit synchronous binary counter/dividers from Texas Instruments, designed for use in military and industrial applications. It features a presettable count capability, allowing the device to be loaded with a specific initial count value. The counter operates synchronously, ensuring stable and predictable timing behavior. With a wide operating voltage range and robust output drive, the SN54LS693J is ideal for frequency division, timing generation, and event counting in demanding environments.
