Separate pins for the photodiode and output stage result in TTL 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.

A 0.1 F bypass capacitor connected between pins 8 and 5 is recommended. CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to prevent damage and/or degradation which may be induced by ESD. 5965-3599E 1-77 The 6N139, HCPL-0701, and CNW139 are for use in CMOS, LSTTL or other low power applications. A 400% minimum current transfer ratio is guaranteed over 0 to 70C operating range for only 0.5 mA of LED current. The 6N138, HCPL-0700, and HCNW138 are designed for use mainly in TTL applications. Current Transfer Ratio (CTR) is 300% minimum over 0 to 70C for an LED current of 1.6 mA (1 TTL Unit load ). A 300% minimum CTR enables operation with 1 TTL Load using a 2.2 k pull-up resistor. Selection for lower input current down to 250 A is available upon request. The HCPL-0701 and HCPL-0700 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. The HCNW139 and HCNW138 are packaged in a widebody encapsulation that provides creepage and clearance dimensions suitable for safety approval by regulatory agencies worldwide.

Notes: 1. DC CURRENT TRANSFER RATI0 (CTR) is defined as the ratio of output collector current, IO, to the forward LED input current, IF, times 100%. 2. Pin 7 Open. 3. Device considered a two-terminal device. Pins 1, 2, 3, and 4 shorted together and Pins 5, 6, 7, and 8 shorted together. 4. Use of a resistor between pin 5 and 7 will decrease gain and delay time. Significant reduction in overall gain can occur when using resistor values below 47 k. For more information, please contact your local HP Components representative. 5. Common mode transient immunity in a Logic High level is the maximum toler- 1-88 able (positive) dVCM /dt of the common mode pulse, VCM, to assure that the output will remain in a Logic High state (i.e., VO > 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). 6. In applications where dV/dt may exceed 50,000 V/s (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 = 220 . 7. Use of a 0.1 F bypass capacitor connected between pins 8 and 5 adjacent to the device is recommended. 8. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage 3000 V rms for 1 second (leakage detection current limit, II-O < 5 A). This test is performed before the 100% production test shown in the VDE 0884 Insulation Related Characteristics Table, if applicable. 9. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage > 6000 V rms for 1 second (leakage detection current limit, II-O < 5 A).
