Description
These products are precision high speed dual comparators designed to operate over a wide range of supply voltages down to a single 5V logic supply and ground. They feature low input currents and high gains.
The open collector of the output stage makes it compatible with TTL as well as capable of driving lamps and relays at currents up to 25mA.

FEATUREs
■ Two independent comparators
■ Supply voltage: +5V to ±15V
■ Typically 80ns response time at ±15V
■ Minimum fan-out of 2 each side
■ Maximum input current of 1µa over operating temperature range
■ Inputs and outputs can be isolated from system ground
■ High common-mode slew rate
