BILATERAL SWITCH
DESCRIPTION
The UTC U74AHC1G66 is an analog switch which transmits
signals from pin(Y or Z) to pin (Z or Y) with an active HIGH enable
input pin (E). When pin E is LOW, the switch is turned off.
FEATURES
* Operation voltage range: 2~5.5V
* Low power dissipation
* Very low ON-resistance: 26Ω (typ.) at VCC=3.0V
16Ω (typ.) at VCC=4.5V
14Ω (typ.) at VCC=5.5V

Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. The input and output voltage ratings may be exceeded if the input and output current ratings are
observed.
3. To avoid drawing VCC current out of pin Z, when switch current flows into pin Y, the voltage drop across
the bidirectional switch must not exceed 0.4V. If the switch current flows into pin Z, no VCC current will
flow out of pin Y. In this case there is no limit for the voltage drop across the switch, but the voltage at
pins Y and Z may not exceed VCC or GND.

Note: With supply voltages at or near 2V, the analog switch on-state resistance becomes very nonlinear.
Only digital signals should be transmitted at these low supply voltages.
