MAX4051/A, MAX4052/A, MAX4053/A
Low-Voltage, CMOS Analog
Multiplexers/Switches
____________________________Typical Operating Characteristics (continued)
(V+ = +5V, V- = -5V, GND = 0V, T
A
= +25°C, unless otherwise noted.)
_____________________________________________________________Pin Descriptions
Digital Inhibit Input. Normally connect to GND. Can be driven
to logic high to set all switches off.
6 6
Negative Analog Supply Voltage Input. Connect to GND for
single-supply operation.
7 7
Ground. Connect to digital ground. (Analog signals have no
ground reference; they are limited to V+ and V-.)
