BL714x High speed 4-channel Digital Isolator 1. Product characteristics  100Mbps signal transmission rate  Powerful isolation performance   ± 100kV / μ s CMTI (TYP)  5kVRMSisolation and withstand voltage  >50 years barrier life  Surge resistance up to 10kV wide power supply voltage range: 2.5V to 5.5V  2.5V to 5.5V level conversion  A wide temperature range: - 40 ℃ to 125 ℃  The default output high level (H) and low level (L) options  Low propagation delay: 11ns (TYP value, 5V power supply)  Low pulse width distortion: 3ns channels and one reverse channel, and both sides have output enable;BL7142 has two forward channels and two reverse channels, and both sides have output enable.If the input side power or signal is lost, the device with suffix l will output low level by default, and the device with suffix h will output high level by default. BL714x device has high insulation ability, which can provide high electromagnetic immunity and low radiation with low power consumption. It helps to prevent noise and surge on data bus or other circuits from entering local grounding terminal, thus interfering or damaging sensitive circuit. High CMTI capability can ensure the correct transmission of digital signal.BL714x device is packaged in 16 pin wide body SOIC (W) package, with 5kVRMSisolation and withstand voltage capability. 4.

The four data channels are completely independent. The input data can be encoded and recovered without distortion at the receiving end.BL7140 has four output channels on the same side;BL7141 has three forward Shanghai Beiling Co., Ltd 1 / 15 021-24261000, 810 Yishan Road, Shanghai GND2 VIA TX RX VOA VIB TX RX VOB VIC TX RX VOC VOD RX TX EN1 VID EN2 GND1 GND2 BL7141 VDD1 VDD2 GND1 VIA GND2 TX RX VOA VIB TX RX VOB VOC RX TX VIC VOD RX TX EN1 GND1 GND2 BL7142 V1.1 VID EN2 PDF
