Receiver Input.

Instruction signal with carrier wave

I

eliminated should be inputted to

this pin. Input signal may be

optionally inverted before fed into

internal decoding circuit.

O Hold Pulse.

As long as proper signal is

O

received, this output is held at “H”

level. (approximately 160ms will

be “0” after key is released.)

O Cyclic Pulse.

When receiving signal is inputted,

CP1/CP2 is inversed. CP1 output

O

may be optionally governed by

(dependent to) the output state of

CP2. See Functional Description

for details.

O Single Pulse.

O When the receiving signal is

O inputted, the active output will be

at “H” level only for a fixed

O

duration of time (approximately

107 msec), then it will return to “L”

level.

I Tx/Rx Matching Code.

I Transmitter Code is compared

I

with a code set at this terminals

and if matched, input is accepted.

OSC Input/Output.

I/O

A resistor and a capacitor are in

parallel connection between this

terminal and Vss.
