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 RDS (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.

LOGIC TABLE CWB 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 (VDD or GND).
