SC9149A/SC9150A
INFRARED REMOTE CONTROL
RECEIVER
DESCRIPTION
The SC9149A/SC9150A are CMOS LSIs designed for use on the
infrared remote control receiver, and when this LSI is used in
combination with SC9148A for transmitter, the remote control
system can be constructed. The SC9149A is DIPcapable of controlling 10 functions, while the SC9150A is DIPtype and is capable of controlling 18 functions.
FEATURES
* Able to output parallel multiple keying signals sent from the
transmitter (The SC9149A is able to output parallel up to 5
functions, while the SC9150A is able to output parallel up to 6
functions.)
* Output for single pulse, hold pulse and cyclic pulse are provided.
(cyclic pulse is available only for SC9150A)
* A single terminal type oscillator by means of CR is provided.
* Code detection circuit provided for code check with the
transmitter prevents inter-ferences from various types of
machines and apparatus.

Instruction signal
with carrier
signal eliminated
is input.
As long as
receiving signal
is input, this
output is held at
“H” level
When receiving
signal is input,
output is
reversed.
When receiving
signal is input,
output is placed
at “H” level only
for a fixed
time.(about
107msec)
Transmitter code
is compared with
a code set at
this terminal and
if they agree
each other, input
is accepted.
A resistor and a
capacitor are
parallel
connected
between this
terminal and
GND.
