74HC1G66GV-74HCT1G66GV
Single-pole single-throw analog switch
Philips Semiconductors Product specification
Bilateral switch 74HC1G66; 74HCT1G66
FEATURES Wide operating voltage range from 2.0to 9.0V Very low ON-resistance:
–45 Ω (typical)at VCC= 4.5V
–30 Ω (typical)at VCC= 6.0V
–25 Ω (typical)at VCC= 9.0V. High noise immunity Low power dissipation Very small 5 pins package Output capability: non standard.
DESCRIPTIONThe 74HC1G/HCT1G66 is a high-speed Si-gate CMOS
device.
The 74HC1G/HCT1G66 provides an analog switch. The
switch has two input/output pins (Y and Z) and an active
HIGH enable inputpin (E). When pinEis LOW, the analog
switch is turned off.
The non standard output currents are equal compared to
the 74HC/HCT4066.
QUICK REFERENCE DATAGND=0 V; Tamb =25 °C; tr =tf= 6.0 ns.
Notes CPD is used to determine the dynamic power dissipation (PDin μW). =CPD× VCC2×fi+∑ ((CL +CS)× VCC2×fo) where:= input frequency in MHz;= output frequency in MHz;= output load capacitance in pF;= maximum switch capacitance in pF;
VCC= supply voltage in Volts; ((CL +CS)× VCC2×fo)= sum of outputs. For HC1G the condition is VI= GNDto VCC.
For HCT1G the condition is VI= GNDto VCC− 1.5V.

ORDERING INFORMATION
PINNING
Philips Semiconductors Product specification
Bilateral switch 74HC1G66; 74HCT1G66
RECOMMENDED OPERATING CONDITIONS
LIMITING VALUES accordance with the Absolute Maximum Rating System (IEC 60134); voltages are referencedto GND (ground=0 V);
see note1.
Notes To avoid drawing VCC current out of pin Z, when switch current flows in pin Y, the voltage drop across the
bidirectional switch must not exceed 0.4 V. If the switch current flows into pin Z, no VCC current will flow out of
terminal Y. In this case there is no limit for the voltage drop across the switch, but the voltage at pinsY and Z may
not exceed VCC or GND. Above 55 °C the value of PD derates linearly with 2.5 mW/K.

Bilateral switch 74HC1G66; 74HCT1G66
Family 74HC1G66 and 74HCT1G66For 74HC1G66: VCC= 2.0, 4.5, 6.0or 9.0 V; note1.
For 74HCT1G66: VCC= 4.5V.
Notes At supply voltages approaching2V, the analog switch ON-resistance becomes extremely non-linear. Thereforeitis
recommended that these devices be used to transmit digital signals only, when using this supply voltage. All typical values are measured at Tamb =25 °C.
