Description:
The Microchip Technology Inc. MCP6541/1R/1U/2/3/4
family of comparators is offered in single (MCP6541,
MCP6541R, MCP6541U), single with Chip Select (CS)
(MCP6543), dual (MCP6542) and quad (MCP6544)
configurations. The outputs are push-pull (CMOS/TTL-
compatible) and are capable of driving heavy DC or
capacitive loads.
These comparators are optimized for low-power,
single-supply operation with greater than rail-to-rail
input operation. The push-pull output of the
MCP6541/1R/1U/2/3/4 family supports rail-to-rail out-
put swing and interfaces with TTL/CMOS logic. The
internal input hysteresis eliminates output switching
due to internal input noise voltage, reducing current
draw. The output limits supply current surges and
dynamic power consumption while switching. This
product family operates with a single-supply voltage as
low as 1.6V and draws less than 1 µA/comparator of
quiescent current.
The related MCP6546/7/8/9 family of comparators from
Microchip has an open-drain output. Used with a pull-
up resistor, these devices can be used as level-shifters
for any desired voltage up to 10V and in wired-OR
logic.
* SC-70-5 E-Temp parts not available at this release of
the data sheet.
MCP6541U SOT-23-5 is E-Temp only.
