_______________Detailed Description
The MAX4598 can be configured as a single 8-channel
or dual 4-channel multiplexer. In the single 8-to-1 multi-
plexer configuration, COMA connects to one of the
eight inputs (NO1 to NO8), GND, or V+ by the address
inputs A0 to A2 (see
Truth Table). In the dual 4-to-1
multiplexer configuration, COMA connects to one of the
four inputs (NO1, NO3, NO5, NO7), GND, or V+, and
COMB connects to one of the four inputs (NO2, NO4,
NO6, NO8) or GND by the address inputs A0 to A2
(see
Truth Table).
The MAX4598 functions as a standard multiplexer
when NLATCH is high. When NLATCH is low, the con-
dition set by A0 to A3 is activated at the rising edge of
LATCH. Otherwise, the outputs remain at the previously
set condition.
__________Applications Information
The MAX4598 construction is typical of most CMOS
analog switches. It has three supply pins: V+, V-, and
GND. The positive and negative power supplies are
used to drive the internal CMOS switches and set the
limits of the analog voltage on any switch. Reverse
ESD-protection diodes are internally connected be-
tween each analog signal pin and V+ and V-. If the volt-
age on any pin exceeds V+ or V- by 0.3V, one of the
ESD diodes starts to conduct. During normal operation
these reverse-biased ESD diodes leak, forming the only
current drawn from V-.
