74HC/HCT4066
FEATURES
Very low “ON” resistance:
50
(typ.) at VCC = 4.5 V
45
(typ.) at VCC = 6.0 V
35
(typ.) at VCC = 9.0 V
Output capability: non-standard
ICC category: SSI.
GENERAL DESCRIPTION
The 74HC/HCT4066 are high-speed Si-gate CMOS
devices and are pin compatible with the “4066” of the
“4000B” series. They are specified in compliance with
JEDEC standard no. 7A.
The 74HC/HCT4066 have 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 belonging analog switch is turned off.
The “4066” is pin compatible with the “4016” but exhibits a
much lower “ON” resistance. In addition, the “ON”
resistance is relatively constant over the full input signal
range.
QUICK REFERENCE DATA
GND = 0 V; Tamb =25 °C; tr =tf =6ns
Notes
1. CPD is used to determine the dynamic power dissipation (PD in W):
a) PD =CPD × VCC2 × fi +∑ {(CL + CS)× VCC2 × fo} where:
b) fi = input frequency in MHz
c) fo = output frequency in MHz
d)
∑ {(CL + CS)× VCC2 × fo} = sum of outputs
e) CL = output load capacitance in pF
f) CS = maximum switch capacitance in pF
g) VCC = supply voltage in V
2. For HC the condition is VI = GND to VCC
For HCT the condition is VI = GND to VCC 1.5 V
