DESCRIPTION
The Calogic CWB211 offers designers high performance at a low
cost. The CWB211 is an excellent choice where capacitance and
switching times are crucial. The device out performs industry
standard DG211 types offering much faster switching speeds, low
R
DS (ON)
and lower capacitance while maintaining high OFF
isolation and good bandwidth. The Calogic CWB211 is configured
to be a pin for pin replacement of existing analog switches
and at the same time upgrading high frequency performance.
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
temperature without a separate power supply.

PIN CONFIGURATION
NOTE: All devices contain diodes to protect inputs 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
DD
or GND).
