TTL, DTL, ECL, CMOS compatible outputs
Description
This device consists of a low-power voltage
comparator designed specifically to operate from
a single supply over a wide range of voltages.
Operation from split power supplies is also
possible.
This comparator also has a unique characteristic
in that the input common-mode voltage range
includes ground, even though operated from a
single power supply voltage.
