74LV4066Quad bilateral switches
FEATURES Optimized for Low Voltage applications: 1.0V to 6.0V Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V Typical VOLP (output ground bounce) < 0.8 V at VCC = 3.3 V,
Tamb = 25 °C.• Very low typ “ON” resistance:
25 at VCC – VEE = 4.5 V
35 at VCC – VEE = 3.0 V
60 at VCC – VEE = 2.0 V• Output capability: non-standard ICC category: SSI
DESCRIPTIONThe 74LV4066 is a low-voltage Si-gate CMOS device that is pin and
function compatible with 74HC/HCT4066.
The 74LV4066 has four independent analog switches. Each switch
has two input/output terminals (nY, nZ) and an active HIGH enable
input (nE). When nE is LOW the corresponding analog switch is
turned off.
The 74LV4066 has an on resistance which is dramatically reduced
in comparison with 74HCT4066.
FUNCTION TABLE
NOTES:= HIGH voltage level= LOW voltage level
QUICK REFERENCE DATAGND = 0 V; Tamb = 25°C; tr =tf 2.5 ns
NOTES: CPD is used to determine the dynamic power dissipation (PD in μW)
PD = CPD × VCC 2 × fi (CL × VCC 2 × fo) where:
fi = input frequency in MHz; CL = output load capacity in pF;
fo = output frequency in MHz; Cs = maximum switch capacitance in pF;
{(CL + CS) × VCC2 × Fo} = sum of the outputs.
VCC = supply voltage in V. The condition is VI = GND to VCC.

RECOMMENDED OPERATING CONDITIONS
NOTE: The LV is guaranteed to function down to VCC = 1.0V (input levels GND or VCC); DC characteristics are guaranteed from VCC = 1.2V to VCC = 5.5V.
ABSOLUTE MAXIMUM RATINGS1, 2In accordance with the Absolute Maximum Rating System (IEC 134).
Voltages are referenced to GND (ground = 0 V).
NOTES:

DC ELECTRICAL CHARACTERISTICSOver recommended operating conditions. Voltages are referenced to GND (ground = 0 V).
NOTE: All typical values are measured at Tamb = 25°C. At supply voltage approaching 1.2V, the analog switch ON-resistance becomes extremely non-linear. Therefore it is recommended that
these devices be used to transmit digital signals only, when using these supply voltages.

GENERAL NOTES:Vis is the input voltage at nY or nZ terminal, whichever is assigned as an input.
Vos is the output voltage at nY or nZ terminal, whichever is assigned as an output.
NOTES: Adjust input voltage Vis is 0 dBm level (0 dBm = 1 mW into 600 �). Adjust input voltage Vis is 0 dBm level at Vos for 1 MHz (0 dBm = 1 mW into 50 �).
