CPC5001G

CPC5001 Dual, One Channel Each Direction Digital Optical Isolator INTEGRATED CIRCUITS DIVISION Features Description • • • • • • • • • The CPC5001 is a dual, non-inverting digital optical isolator with buffered-logic inputs and open-drain outputs. Channel 1 propagates a signal from Side A to Side B, while Channel 2 sends a signal from Side B to Side A. It provides galvanic isolation up to 3750Vrms. When the two sides are powered by supplies with different voltages, it also functions as a logic level translator for supply voltages as low as 2.7V or as high as 5.5V. Available in 8-pin DIP and surface mount packages, it functionally replaces two logic buffers and two single-channel optoisolators. Internal bandgap references regulate the LED drive currents to 3mA to reduce peak power requirements.

Buffered signals will always return to their proper value after a transient interruption at either side.

Typical values are characteristic of the device at 25°C, and are the result of engineering evaluations. They are provided for information purposes only, and are not part of the manufacturing testing requirements. Specifications cover the operating temperature range TA = -40°C to +85°C, unless otherwise specified. Side A is the same as Side B, and Channel 1 is the same as Channel 2; therefore, the electrical and timing specifications apply to both Sides/Channels. 1.7 Electrical Parametric Specifications Parameter Conditions Symbol Min Typ Max Units Supply Voltage ISINK=6mA VDD 2.7 - 5.5 V Supply Current VDD=3.3V, ISINK=0mA - 4.3 - - 4.4 - - 5 7.5 Electrical ISINK=6mA IDD VDD=5.5V, ISINK=0mA, TA=25°C Leakage Current IN1=OUT2=VDDA, IN2=OUT1=VDDB ILEAK - 0.01 10 Falling Input Low Threshold 2.7V < VDD < 5.5V VIL 0.3VDD 0.42VDD - Rising Input High Threshold 2.7V < VDD < 5.5V VIH - 0.57VDD 0.7VDD Hysteresis 2.7V < VDD < 5.5V VHYST - 0.15VDD - - 0.21 0.35 - 0.42 0.7 Output Drive VDD=2.7V, ISINK=3mA VDD=2.7V, ISINK=6mA VOL VDD=3.3V, ISINK=6mA Output Temperature Coefficient mA A V V V - 0.38 - 2.7V < VDD < 5.5V, ISINK=6mA TC - +1.2 - mV/°C Conditions Symbol Min Typ Max Units ISINK=6mA, CLOAD=20pF fMAX - 5 - MHz VDDA=VDDB=3.3V, RPUA=475, RPUB=475 CIN_A=CIN_B=20pF VIN=0.5VDD_IN to VOUT=0.5VDD_OUT tPHL 40 60 100 ns tPLH 40 135 250 tPLH - tPHL PWD -25 75 170 ns Symbol Min Typ Max Units 1.8 Timing Specifications Parameter Timing Clock Frequency Propagation Delay (see Note 1) High to Low Low to High Pulse Width Distortion Note 1: See “Switching Waveforms” on page 5. 1.9 Common Mode Rejection Specifications Parameter Conditions Common Mode Rejection Common Mode Transient Immunity 4 VCM=20VP-P , VDD=3.3V, TA=25°C VOUT = High VOUT>2V CMH 5 - - VOUT = Low VOUT
