:
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.
• Low Quiescent Current: 100 µA (typical)
• Input Offset Voltage: ±3 mV (typical)
• Rail-to-Rail Input: VSS - 0.3V to VDD + 0.3V
• CMOS/TTL Compatible Output
• Wide Supply Voltage Range: 1.8V to 5.5V
• Available in Single, Dual, and Quad
• Packages: SC70-5, SOT-23-5, SOIC, MSOP,
TSSOP
This family operates with single supply voltage of 1.8V
to 5.5V while drawing less than 100 µA/comparator of
quiescent current (typical).
