Fairchild Semiconductor's New Family of 3.3V and 5V Split Darlington Optocouplers Offer Low Power Consumption and High Performance for RS-232 to 3.3V Logic Interfacing.Business Editors/High-Tech Writers SAN JOSE, Calif.--(BUSINESS WIRE)--Oct. 6, 2003 Fairchild Semiconductor (NYSE NYSE See: New York Stock Exchange : FCS FCS - Frame Check Sequence ) today announces the expansion of its family of split darlington optocouplers with five new products in both single- dual-channel configurations offering 3.3V or 5V operation voltages for low power consumption. The dual-channel HCPL HCPL Home Care Practice Licence (UK certification) HCPL Holmes County Public Library HCPL Hybrid Capillary Pumped Loop 0730, HCPL0731 optocouplers offer 5V operation and SOIC-8 packaging for optimum mounting density. The single-channel FOD FOD - /fod/ [Abbreviation for "Finger of Death", originally a spell-name from fantasy gaming] To terminate with extreme prejudice and with no regard for other people. From MUDs where the wizard command "FOD " results in the immediate and total death of 070L, FOD270L and dual channel FOD073L devices, at 3.3V operation voltage, further reduce power consumption by 33%, versus conventional 5V parts. Fairchild's new darlington optocouplers are pin-for-pin compatible with other leading suppliers' HCPL devices. Typical applications for these products include RS-232 line receiver, LVTTL LVTTL Low Voltage Transistor Transistor Logic (AMCC) LVTTL Low Voltage Transistor to Transistor Logic to LVCMOS LVCMOS Low Voltage Complementary Metal Oxide Semiconductor LVCMOS Low-Voltage Complementary Metal-Oxide Semiconductor (family of logic integrated circuits) LVCMOS Low Voltage Cmos interfacing, AC line voltage status indicator, ground loop isolation and data multiplexing applications. These darlington optocouplers utilize a split darlington output configuration separating the input photodiode and first stage gain from the output transistor, to permit lower output saturation voltage (0.1V) and higher-speed operation than traditional darlington phototransistor A transistor that uses light rather than electricity to cause an electrical current to flow from one side to the other. It is used in a variety of sensors that detect the presence of light. optocouplers. Fairchild's new family of optocouplers offer low input current (0.5mA), high (1800% typical) current transfer ratio (CTR See click-through rate. ), high standard isolation voltage rating (5KV in single channel 8-pin DIP) and guaranteed performance over a wide (0-70 degrees Celsius) temperature range. In the dual channel devices, a resistor integrated between the emitter and base of each output transistor provides superior temperature stability. "To address the ever decreasing power budget faced by system designers," said John Constantino, strategic marketing manager of Fairchild's Optoelectronics group, "Fairchild's new line of high performance optocouplers offer vital power savings without sacrificing performance." These products expand Fairchild's solutions for power conversion and isolation, which includes switching regulators, MOSFETs, PWM (Pulse Width Modulation) A modulation technique that generates variable-width pulses to represent the amplitude of an analog input signal. Like its fixed-width pulse density modulation (PDM) cousin, the output switching transistor is on more of the time for a controllers, LDOs, rectifiers and diodes.
