ISO7762DBQR – 16-SSOP Pinout

Notes

ISO7762DBQR is a 4-channel digital isolator with integrated isolation. Pins 1–8 represent the primary side (VCC1, inputs INA–IND, outputs OUTE–OUTF, GND1), and pins 9–16 represent the secondary side (GND2, inputs INE–INF, outputs OUTD–OUTA, VCC2). The device provides galvanic isolation between the two sides via the internal isolation barrier.

VCC1 = VCC2 = 5 V ±10% (over recommended operating conditions unless otherwise noted)

The ISO776x family of devices is a high-performance, six-channel digital isolators. The ISO776x family of devices uses single-ended CMOS-logic switching technology. The voltage range is from 2.25 V to 5.5 V for both supplies, VCC1 and VCC2. When designing with digital isolators, keep in mind that because of the single-ended design structure, digital isolators do not conform to any specific interface standard and are only intended for isolating single-ended CMOS or TTL digital signal lines. The isolator is typically placed between the data controller (that is, μ C or UART), and a data converter or a line transceiver, regardless of the interface type or standard.
