74V2G66 DUAL BILATERAL SWITCH HIGH SPEED: tPD = 0.3ns (TYP.) at VCC =5V tPD = 0.4ns (TYP.) at VCC =3.3V LOW POWER DISSIPATION: ICC =1µA(MAX.) at TA = 25°C LOW "ON" RESISTANCE: SOT23-8L RON =6.5? (TYP.) AT VCC =5VII/O =1mA RON =8.5?(TYP.) AT VCC =3.3VII/O =1mA SINE WAVE DISTORTION: ORDER CODES 0.04% AT VCC =3.3Vf =1KHz PACKAGE T & R WIDE OPERATING RANGE: VCC (OPR) = 2V TO 5.5V SOT23-8L 74V2G66STR IMPROVED LATCH-UP IMMUNITY The C input is provided to control the switch and it’s compatible with standard CMOS output; the DESCRIPTION switch is ON (port I/O is connected to Port O/I) The 74V2G66 is an advanced high-speed CMOS when the C input is held high and OFF (high DUAL BILATERAL SWITCH fabricated in silicon impedance state exists between the two ports) gate C2MOS
