Description

The HCPL-3700 and HCPL-3760 are voltage/current threshold detection optocouplers. The HCPL-3760 is a low-current version of the HCPL-3700. To obtain lower current operation, the HCPL-3760 uses a highefficiency AlGaAs LED which provides higher light output at lower drive currents. Both devices utilize threshold sensing input buffer ICs which permit control of threshold levels over a wide range of input voltages with a single external resistor.

diodes to protect the buffer and LED from a wide range of overvoltage and over-current transients. Because threshold sensing is done prior to driving the LED, variations in optical coupling from the LED to the detector will have no effect on the threshold levels.

The HCPL-3700's input buffer IC has a nominal turn on threshold

of 2.5 mA (ITH +) and 3.7 volts (VTH +).

The buffer IC for the HCPL-3760 was redesigned to permit a lower input current. The nominal turn on threshold for the HCPL-3760

is 1.2 mA (ITH +) and 3.7 volts (VTH +).

The high gain output stage features an open collector output providing both TTL compatible

saturation voltages and CMOS compatible breakdown voltages.

By combining several unique functions in a single package, the user is provided with an ideal component for industrial control computer input boards and other applications where a predetermined input threshold level is desirable.
