XL551 - LinCMOS process
The XL551 is a monolithic timing circuit fabricated using LinCMOS ™process.
The timer is fully compatible with CMOS, TTL, and MOS logic and operates at frequencies up to 2 MHz.
Compared to the XL555 timer, this device uses smaller timing capacitors because of its high input impedance.
As a result, m
