A separate unregulated power supply can be used. 2 IREDC IRED cathode, do not connect for standard operation 3TXD Transmitter data input. Setting this input above the threshold turns on the transmitter. This input switches the IRED with the maximum transmit pulse width of about 50 µs. IHigh 4RXD Receiver output. Normally high, goes low for a defined pulse duration with the rising edge of the optical input signal. Output is a CMOS tri-state driver, which swings between ground and Vcc. Receiver echoes transmitter output. OLow 5SD Shut down. Logic low at this input enables the receiver, enables the transmitter, and un-tri-states the receiver output. It must be driven high for shutting down the transceiver. IHigh 6 VCC Power supply, 2.4 V to 3.6 V. This pin provides power for the receiver and transmitter drive section. Connect VCC1 via an optional filter. 7 GND Ground 19284 |
