HT654x Push-Pull Output Sub-Microamp Comparators Description The Microchip Technology Inc. HT6541/2/3/4 family of comparators is offered in single (HT6541), single with chip select (HT6543), dual (HT6542) and quad (HT6544) 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 HT6541/2/3/4 family supports rail-to-rail output 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.
