FEATURES  
DESCRIPTIO  
The LTC®221 and LTC222 are micropower, quad CMOS  
analog switches which typically dissipate only 250µW  
from ±15V supplies and 40µW from a single 5V supply.  
Onboard latches allow the LTC221 and LTC222 to inter-  
face directly to most microprocessor buses. The switches  
have 65typical on resistance and a very high off resis-  
tance. A break before make characteristic is inherent in  
these switches to prevent the shorting of two channels.  
Thesignalrangeis±15Vwithasupplyvoltageof±15Vand  
0Vto5Vwithasingle5Vsupply.Theswitcheshavespecial  
charge compensation circuitry which greatly reduces  
charge injection to a maximum of±25pC (±15V supplies).
