Logic 1 = V+; unless otherwise specified)

Notes: 5. Typical PIN diode junction capacitance is 70 pF.

6. The temperature coefficient of the receiver threshold setting is low. Current detection thresholds are

above the DC ambient condition. Settings of RS4-0 of less than 00010 are not practical because of

noise. RX threshold settings are roughly linear following the formula:

Threshold (nA) = (RX setting + 1) * 20 + 36.

7. Turn-around time is the time taken for the PIN diode receiver to recover from the IR energy from the

local transmitter. The remote end of the link must wait for this time after receiving data before

transmitting a reply. This time may be reduced to <1 ms by good IR shielding between the transmit LED

to the PIN diode.

Logic 0 = 0 V, Logic 1 = V+, unless otherwise specified)

Notes: 8. Typical LED junction capacitance is 20 pF.
