A separate unregulated CC2 1IREDA power supply can be used. Receiver output. Normally high, goes low for a defined pulse duration with the rising 2RXD edge of the optical input signal. Output is a CMOS tri-state driver, which swing s OLow between ground and V . Receiver echoes transmitter output. logic Transmitter data input. Setting this input above the threshold turns on the transmitter. 3TXD IHigh This input switches the IRED with the maximum transmit pulse width of about 100 s. Shutdown. Logic low at this input enables the receiver, enables the transmitter, and 4SD un-tri-states the receiver output. It must be driven high for shutting down the IHigh transceiver. 5V Reference for the logic swing of the output and the input logic levels. I logic Power supply, 2.4 V to 5.5 V. This pin provides power for the receiver and transmitter 6V CC drive section. Connect V via an optional filter.
