Very high speed operation at low power levels is achieved. These parts are available in a 16-pin wide body SOIC package. Three speed grade options (1, 10, 100 Mbps) are available and achieve typical propagation delay of less than 10 ns. Block Diagram High-speed operation: DC – 150 Mbps Low propagation delay: <10 ns Wide Operating Supply Voltage: 2.375–5.5 V Low power: I1 + I2 < 12 mA/channel at 100 Mbps Precise timing: 2 ns pulse width distortion 1 ns channel-channel matching 2 ns pulse width skew 2500 VRMS isolation Transient Immunity: >25 kV/µs Tri-state outputs with ENABLE control DC correct No start-up initialization required <10 µs Startup Time High temperature operation: 125 °C at 100 Mbps 100 °C at 150 Mbps Wide body SOIC-16 package Isolated switch mode supplies Isolated ADC, DAC Motor control Power factor correction systems UL recognition:2500 VRMS for 1 Minute per UL1577 CSA component acceptance notice #5A * All Pending VDE certification conformity DIN EN 60747-5-2 (VDE0884 Part 2):2003-01 DIN EN60950(VDE0805): 2001-12;EN60950:2000 VIORM = 560 VPEAK Si8441 Si8442 B1 A1 A3 A4 A2 B3 B4 B2 Si8440 A1 A3 A4 A2 B3 B4 B2 B1 A1 A3 A4 A2 B3 B4 B2 B1 NC EN1 EN1 EN2 EN2 EN2 Pin Assignments Wide Body SOIC V DD1 GND1 A1 A3 A4 EN1 GND1 A2 1 2 3 4 5 6 7 8 Top View V DD2 GND2 B2 B1 B4 B3 GND2 EN2 9 12 11 10 13 14 15 16 |
