There are four package options in the Si871x family: gull wing DIP-8, SOIC-8, stretched SO-6, and LGA-8. All are surface mount packages, and are packages most often used by optocouplers. The products certified to 3.75 kV withstand isolation rating are available in the SOIC-8 and gull wing DIP-8 packages. The stretched SO-6 and the LGA-8 packages have the creepage distance required to support the 5 kV withstand isolation rating. The LGA-8 package is foot print compatible with the 400 mil DIP-8 package offered by optocoupler suppliers. The Si87xx family has three different output options available. The base Si8710 device consists of the LED emulator input and the open-collector output. There are two additional device configurations available: the Si8711 adds an integrated pull-up resistor, and the Si8712 includes a dedicated enable pin that can asynchronously control the output. Both the Si871xA and Si871xB group of devices are specified up to a 15 Mbps data rate. The Si871xC is a lower speed device, specified for a 1 Mbps data rate.
