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).
