Additional Details

The TC40193BP operates within a supply voltage range of 3V to 18V. It is available in a 16-pin DIP (Dual In-line Package), making it easy to prototype and implement in through-hole PCB designs. The operating temperature range is typically -40°C to +85°C. Its synchronous counting mechanism ensures that all flip-flops change state simultaneously on the rising or falling edge of the clock pulse, eliminating glitches and ensuring stable, predictable operation. The carry and borrow outputs simplify cascading multiple counters to achieve higher count values, enabling its use in more complex counting systems.  The device's clear input provides a convenient way to reset the counter to a known initial state, which is essential for many applications requiring precise timing or control.
