PRODUCTION DATA
PIN | I/O(1) | DESCRIPTION | |
---|---|---|---|
NO. | NAME | ||
1 | VBUS1 | — | Input Power Supply for Side 1. If a 4.25 V to 5.5 V (example USB power bus) supply is available connect it to VBUS1. In this case an internal LDO generates V3P3V1. Else, connect VBUS1 and V3P3V1 to an external 3.3 V power supply. |
2 | GND1 | — | Ground 1. Ground reference for Isolator Side 1. |
3 | V3P3V1 | — | Power Supply for Side 1. If a 4.25 V to 5.5 V supply is connected to VBUS1 connect a bypass capacitor between V3P3V1 and GND1. In this case an internal LDO generates V3P3V1. Else, connect VBUS1 and V3P3V1 to an external 3.3 V power supply. |
4 | NC | — | Preferably leave floating or connect to V3P3V1. It is also OK to connect to GND1. |
5 | NC | — | Preferably leave floating or connect to V3P3V1. It is also OK to connect to GND1. |
6 | UD- | I/O | Upstream facing port D-. |
7 | UD+ | I/O | Upstream facing port D+. |
8 | GND1 | — | Ground 1. Ground reference for Isolator Side 1. |
9 | GND2 | — | Ground 2. Ground reference for Isolator Side 2. |
10 | DD+ | I/O | Downstream facing port D+. |
11 | DD- | I/O | Downstream facing port D-. |
12 | PIN | I | Upstream pull-up enable. If this pin is low, pull-up on DD+ and DD- is not recognized. |
13 | NC | — | Preferably leave floating or connect to V3P3V2. It is also OK to connect to GND2. |
14 | V3P3V2 | — | Power Supply for Side 2. If a 4.25 V to 5.5 V supply is connected to VBUS2 connect a bypass capacitor between V3P3V2 and GND1. In this case an internal LDO generates V3P3V2. Else, connect VBUS2 and V3P3V2 to an external 3.3 V power supply. |
15 | GND2 | — | Ground 2. Ground reference for Isolator Side 2. |
16 | VBUS2 | — | Input Power Supply for Side 2. If a 4.25 V to 5.5 V (example USB power bus) supply is available connect it to VBUS2. In this case an internal LDO generates V3P3V2. Else, connect VBUS2 and V3P3V2 to an external 3.3 V power supply. |
