NOTE: All devices contain d iodes to protect inp uts against
damage due to high static voltages or electric fields;
however, it is advised that precautions be taken not to
exceed the maximum recommended input voltages. All
unused inputs must be connected to an appropriate logic
level (V
or GND).

DESCRIPTION
The Calogic CWB211 offers designers high performance at a low
cost. The CWB21 1 is an excellent choice where capacitance an d
switching times are crucial. The device out performs industry
standard DG211 types offe ring mu ch f ast er sw it chi ng speeds, low
R
and lower capacitance while maintaining high OFF
DS (ON)
isola ti on and good ban dwidt h. The Cal ogic CWB 211 is configured
to be a pin for pin replacement of existing analog switches
and at the same time upgrading high frequency perfo rma nce.
Manufactured on the Calogic proprietary low voltage CMOS
combined with high speed DMOS FETs, the device is TTL
compatible utilizing an on-chip reference to provide constant
logic switching over a wide range of supply voltages and
temperatur e without a separ at e power sup ply.
