4 Functional Description
4.1 Introduction
The CPC5001 combines the functions of two input
buffer/LED driver gates and two unidirectional logic
optoisolators in a single 8-pin package. The isolators
are arranged for one input and one output at each side
of the isolation barrier, which enables Channel 1 to
send signals from side A to Side B, and Channel 2 to
send signals from the Side B to the Side A. If different
supply voltage levels are used at each side, then the
part, in conjunction with its external pullup resistors,
will perform logic level translation for VDD between
2.7V and 5.5V at either side.
The part provides galvanic isolation for voltages up to
3750Vrms. Its CMOS circuitry includes a bandgap
reference to ensure that the LEDs receive consistent
drive current levels over the allowed range of VDD
voltages. The supply currents at IDDA and IDDB are
much smaller than those required by bipolar solutions,
and are stable over temperature. The circuits also
ensure that the IDD current into each VDD package pin
remains constant for both high and low input signals.
This can greatly reduce the size of external decoupling
capacitors when compared with optoisolators
fabricated in a bipolar process wherein the supply
current can double when the LED is on.
The rotationally symmetric pinout ensures that the
part operates normally even if installed with 180°
rotation.
