Présentation
Description
Key features include asynchronous clear capability, which resets the counter regardless of the clock signal. It also has a maximum clock frequency of approximately 100 MHz at 5 V, making it suitable for high-speed applications. The counter advances on the negative edge of the clock, offering versatility in synchronous systems.
Packaged in a TSSOP-16, the SN74LV4040APWR is compact, allowing for efficient use of PCB space. It is widely used in digital applications like timers, frequency dividers, and event counters. Reliability is further enhanced by its TTL-compatible inputs and outputs, ensuring easy integration with other digital components.
