Data Sheet
HCPL-270L/070L/273L/073L
Low Input Current, High Gain, LVTTL/LVCMOS
Compatible Optocouplers
Description
These high gain series couplers use a Light Emitting Diode
and an integrated high gain photodetector to provide
extremely high current transfer ratio between input and
output. Separate pins for the photodiode and output stage
result in LVTTL compatible saturation voltages and high
speed operation. Where desired, the VCC and VO terminals
may be tied together to achieve conventional photodarlington operation. A base access terminal allows a gain
bandwidth adjustment to be made.
These optocouplers are for use in LVTTL/LVCMOS or other
low power applications. A 400% minimum current transfer
ratio is guaranteed over 0°C to +70°C operating range for
only 0.5 mA of LED current.
Features
3.3 V/5 V dual supply voltages
Low power consumption
High current transfer ratio
Low input current requirements: 0.5 mA
LVTTL/LVCMOS compatible output
Performance guaranteed over temperature 0°C to
+70°C
Base access allows gain bandwidth adjustment
High output current: 60 mA
Safety approval, UL, IEC/EN/DIN EN 60747-5-2, CSA
Applications
The HCPL-070L and HCPL-073L are surface-mount
devices packaged in an industry-standard SOIC-8 footprint.
The SOIC-8 does not require through holes in a PCB. This
package occupies approximately one-third the footprint
area of the standard dual-in-line package. The lead profile is
designed to be compatible with standard surface-mount
processes.
Ground isolate most logic families: LVTTL/LVCMOS
Low input current line receiver
High voltage insulation
EIA RS-232C line receiver
Telephone ring detector
V AC line voltage status indicator: low input power
dissipation
Low power systems: ground isolation
CAUTION! It is advised that normal static precautions be taken in handling and assembly of this component to prevent
damage and/or degredation which may be induced by ESD.

( 2.0 V). Common mode transient immunity
in a Logic Low level is the maximum tolerable (negative) dVCM/dt of the common mode pulse, VCM, to assure that the
output will remain in a Logic Low state (i.e., VO < 0.8 V).
7. In applications where dV/dt may exceed 50,000 V/µs (such as static discharge) a series resistor, RCC, should be included to
protect the detector IC from destructively high surge currents. The recommended value is RCC = 110 Ω.
8. Use of a 0.1 µF bypass capacitor connected between pins 5 and 8 adjacent to the device is recommended.
9. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage > 4500 Vrms for 1 second
(leakage detection current limit, II-O < 5 µA).
10. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage > 6000 Vrms for 1
second (leakage detection current limit, II-O < 5 µA).
11. Measured between the LED anode and cathode shorted together and pins 5 through 8 shorted together.
