Description
The Microchip Technology, Inc. MCP6561/1R/1U/2/4
families of CMOS/TTL compatible comparators are
offered in single, dual, and quad configurations.
These comparators are optimized for low power 1.8V,
single-supply applications with greater than rail-to-rail
input operation. The internal input hysteresis eliminates
output switching due to internal input noise voltage,
reducing current draw. The push-pull output of the
MCP6561/1R/1U/2/4 family supports rail-to-rail output
swing, and interfaces with CMOS/TTL logic. The output
toggle frequency can reach a typical of 4 MHz (typical)
while limiting supply current surges and dynamic power
consumption during switching.
This family operates with single supply voltage of 1.8V
to 5.5V while drawing less than 100 µA/comparator of
quiescent current (typical).
