CM2500-05  
CMOS Multiplexer for Keypad Switches  
Product Description  
Features  
Functionally equivalent to a five-diode pair network  
The CM2500-05 is a CMOS multiplexer for keypad  
switches. The device is functionally equivalent to a  
five-diode pair network. However, each channel in this  
network has virtually no voltage drop from input to out-  
put under light load. All inputs and outputs have an  
Up to 60% space saving vs. discrete solution  
Flexibility in design with "separate" outputs  
100kpull-up resistors on outputs  
Voltage drop of less than 10mV under light loads  
16-lead QFN package - 3mm x 3mm, 0.5mm pitch  
Lead-free version available  
internal pull up to V  
.
CC  
This device is particularly well suited for portable elec-  
tronics (e.g. mobile handsets, PDAs, notebook com-  
puters) because of its small package format. This  
product is ideal for converting the logic of keypad  
switches where each switch pulls two sense lines low.  
The keypad multiplexer channels are set up in series  
on the keypad sense lines such that it will interface  
directly to the CPU chipset.  
Applications  
Enables more keys from current keyboard control-  
ler without extra I/O from chipset  
Keypad switches in mobile electronics  
Roller pad or joystick in mobile electronic products  
Wireless Handsets  
The CM2500-05 is available in a space-saving, low-  
profile 16-lead QFN package. This presents a 60%  
saving in space when compared with a discrete imple-  
mentation. The CM2500-05 is available with optional  
lead-free finishing.
