DESCRIPTION
The 74H1G66 is a CMOS SINGLE BILATERAL SWITCH fabricated in silicon gate C2MOS technology. It achieves high speed performance combined with true CMOS low power consumption.
The C input is provided to control the switch and it’s compatible with standard CMOS output; the switch is ON (port I/O is connected to Port O/I) when the C input is held high and OFF (high impedance state exists between the two ports) when C is held low.
All inputs and output are equipped with protection circuits against static discharge, giving them ESD immunity and transient excess voltage.

■ HIGH SPEED: tPD = 4ns (TYP.) at VCC = 4.5V
■ LOW POWER DISSIPATION: ICC = 1µA(MAX.) at TA=25°C
■ HIGH NOISE IMMUNITY: VNIH = VNIL = 28% VCC (MIN.)
■ LOW "ON" RESISTANCE: RON = 50Ω (TYP.) AT VCC = 9V II/O = 100µA
■ SINE WAVE DISTORTION: 0.042% AT VCC = 4V f = 1KHz
■ WIDE OPERATING RANGE: VCC (OPR) = 2V TO 12V
