■ Precautions for Operation

1. When this infrared remote control detecting unit shall be adopted for wireless remote control, please use the following signal format .

ꢀ(NEC code,RC-6code etc.)

・Total duty ratio Dt (Emitting time ꢀtN / Transmitting time for 1 block T) : 40% or less.

N=1

・ON signal time TON：200μs or more.

Transmitting time for 1 block:T

T_ON

t₁

t₂

t₃

t_n

Dt =( _tN/T)×100 (%)

N=1

In case the signal format of total duty and/or ON/OFF signal time dosen`t meet the conditions noted above, there is a

case that reception distance much reduces or output dose not appear.

2. Use the light emitting unit (remote control transmitter), in consideration of performance, characteristics, operating conditions of

light emitting device and the characteristics of the light detecting unit.

3. Pay attention to a malfunction of the light detecting unit when the surface is stained with dust and refuse.

Care must be taken not to touch the light detector surface.

If it should be dirty, wipe off such dust and refuse with soft cloth so as to prevent scratch. In case some solvents are required, use

methyl alcohol, ethyl alcohol or isopropyl alcohol only.

Also, protect the light detecting unit against flux and others, since their deposition on the unit inside causes reduction of the

function, fading of markings such as the part number.

4. The shield case should be grounded on PCB pattern.

(The area across the shield case and the GND terminal is internally non-conductive.)

5. Do not apply unnecessary force to the terminal and the case.

6. Do not push the light detector surface (photodiode) from outside.

7. To avoid the electrostatic breakdown of IC, handle the unit under the condition of grounding with human body, soldering iron, etc.

8. Do not use hole and groove set in the case of the light detecting unit for other purposes, since they are required to maintain the

specified performance.

9. External Circuit Examples (Mount the outer parts as near the unit as possible).

GND

R₁

(Circuit parameters)

V_OUT

V_O

R1=47Ω±5%

C1=47μF

In setting R1 and C1, use suitable values after considering under the real condition

The circuit constant is a example. It is difference from mounting equipment. Please select it by your mounting equipment.

This device has a transistor as protection element between VCC and GND to improve anti-static electricity proof.

Please be carefully not to apply exceeding the absolute maximum ratings of applying voltage and continuous high voltage spike

noise because there is cases that transistor will be short by secondary breakdown generally. In order to do difficultly, Please add CR

filter(47Ω(1/10W), 10μF or more)such as external circuit example above near VCC.
