It achieves high speed propagation delay and VERY LOW ON resistances while maintaining true CMOS low power consumption. This bilateral switch handles rail to rail analog and digital signals that may vary across the full power supply range (from GND to VCC ). The C input is provided to control the switch and it’s compatible with standard TTL output; the switch is ON (port I/O is connected to Port O/I) SOT23-5L SOT323-5L ORDER CODES PACKAGE T&R SOT23-5L SOT323-5L 74V1T66STR 74V1T66CTR when the C input is held high and OFF (high impedance state exists between the two ports) when C is held low. It can be used in many application as Battery Powered System, Test Equipment. It’s available in the commercial and extended temperature range in SOT23-5L and SC-70-5L package. All inputs and output are equipped with protection circuits against static discharge, giving them ESD immunity and transient excess voltage.
