Low-Voltage, Dual-Supply,
SPDT Analog Switch with Enable
The MAX4564 is a dual-supply SPDT CMOS analog
switch. The MAX4564 has break-before-make switch-
ing. The CMOS switch construction provides Rail-to-
Rail
power. Each of the two switches is independently con-
trolled by a TTL/CMOS-level-compatible digital input.
Do not exceed the absolute maximum ratings because
stresses beyond the listed ratings may cause perma-
nent damage to the device. Proper power-supply
sequencing is recommended for all CMOS devices.
Always sequence V+ on first, then V-, followed by the
logic inputs NO, NC, or COM. If power-supply
sequencing is not possible, add two small-signal
diodes (D1, D2) in series with supply pins. Adding
diodes reduces the analog signal range to one diode
drop below V+ and one diode drop above V-, but does
not affect the device’s low switch resistance and low
leakage characteristics.
