Si8440/1/2Si8440/1/2QUAD-CHANNEL DIGITAL ISOLATORFeaturesApplicationsSafety Regulatory ApprovalsDescriptionSilicon Lab's family of digital isolators are CMOS devices that employan RF coupler to transmit digital information across an isolationbarrier. Very high speed operation at low power levels is achieved.These parts are available in a 16-pin wide body SOIC package. Threespeed grade options (1, 10, 100Mbps) are available and achievetypical propagation delay of less than 10ns.Block Diagram󰂄High-speed operation: DC – 150Mbps󰂄Low propagation delay:<10ns󰂄Wide Operating Supply Voltage: 2.375–5.5V󰂄Low power: I1 + I2 < 12mA/channel at 100Mbps󰂄Precise timing:2ns pulse width distortion1ns channel-channel matching2ns pulse width skew󰂄2500VRMS isolation󰂄Transient Immunity: >25kV/µs󰂄Tri-state outputs with ENABLE control󰂄DC correct󰂄No start-up initialization required󰂄<10µs Startup Time󰂄High temperature operation: 125°C at 100Mbps100°C at 150Mbps󰂄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 VPEAKSi8441Si8442B1A1A3A4A2B3B4B2Si8440A1A3A4A2B3B4B2B1A1A3A4A2B3B4B2B1NCEN1EN1EN2EN2EN2Pin AssignmentsWide Body SOICVDD1GND1A1A3A4EN1GND1A212345678Top ViewVDD2GND2B2B1B4B3GND2EN2912111013141516元器件交易网www.cecb2b.comSi8440/1/2
