Ei8LC05 thru Ei8LC15 Low Capacitance, Bidirectional, Monolithic TVS Diode Network independent for multiple I/O port protection. These monolithic diode array networks can be used to protect combinations of 8 unidirectional or bi-directional lines. They provide ESD and surge protection for sensitive power and I/O ports. The 8LC series TVS diode array will meet the surge and ESD per IEC 1000-4-2. FEATURES · 500 watts Peak Pulse Power (tp = 8 x 20 µs) · ESD and Transient protection for data, signal and Vcc bus to IEC 1000-4-2 (formerly IEC 801-2) · Protects up to 4 bi-directional lines · Standoff voltages from 5 to 15 V · Low capacitance for high speed interfaces · Low clamping voltage · ESD protection >8kV Applications · ESD & surge protection for power lines & I/O ports · TTL and MOS Bus Lines · RS-232, Rs-422 and RS-485 data lines · High speed logic · High speed data & video transmission DESCRIPTION The Ei8LC series of monolithic transient voltage suppressors are designed for applications where voltage transients, caused by electrostatic discharge (ESD) and other induced voltage surges, can permanently damage voltage sensitive components. These TVS diodes are characterized by their high surge capability, extremely fast response time and low onresistance. The Ei8LC series consists of bi-directional diode arrays with low input capacitances and is specifically designed to protect multiple or single data lines with each channel being electrically MECHANICAL CHARACTERISTICS · Available in 8 lead SOIC and PDIP · Solder temperature : 265°C for 10 seconds Schematic 1 8 2 7 3 6 4 5 Part Numbers May Be Marked With "IMP" or "Ei."
