Description: 

DC Power Supply Voltageļ¼š4.5V-5.5V(Tup: 5V)

Operating Temperature : -40-+85 °C

IO Drive : Sink Current (Low level drive) 20mA,source current(High level drive) 270uA

16 Channel selectable high and low level output.

16 Channel output: 0-9,*# ABCD

8 kinds of Mode selection

PCB Size : 50x20MM

This decoding module is for mobile and fixed telephone voice dialing decoding function , has 16 channels, 8 kinds of selectable output function, and leads to STD signal to use as a microcontroller interrupt signal, very convenient to embed all kinds for mobile and fixed telephoneremote remote control, remote control decoding key value. 
12 channels outputs decode mobile and fixed telephone keys (0-9, * #).Another 4 channels output(ABCD) can use "DTMF Dial" Software control.

(Default mode)

Non-locking (Momentary )

High-level

High level output, 1S later goes low level

 

 

self-locking (Toggle)

High-level

Level inversion

High level goes low, Low level goes high

 

 

Inter-locking (Latch)

High-level

Interlock, it is maintained high level signal of output , until next output high level, then recover to low output level

 

 

Delay 10S

(Momentary )

High-level

High level output, 10S later goes low level

 

 

Non-locking (Momentary )

Low level

Low level output, 1S later goes high level

 

 

self-locking (Toggle)

Low level

Level inversion (After reset High level)

High level goes low, Low level goes high

 

 

Inter-locking (Latch)

Low level

Interlock, it is maintained low level signal of output , until next output low level, then recover to high output level

 

Delay 10S

(Momentary )

Low level

Low level output, 10S later goes high level
