General Description

The MAX4714 is a low on-resistance, low-voltage sin-

gle-pole/double-throw (SPDT) analog switch that oper-

ates from a single +1.6V to +3.6V supply. The

MAX4714 has break-before-make switching. This

device also has fast switching speeds (t

= 18ns,

max, t

OFF

= 12ns, max).

When powered from a +3V supply, the MAX4714 fea-

tures 0.8Ω (max) on-resistance (R

), with 0.18Ω (max)

matching and flatness. The digital logic input is 1.8V

CMOS compatible when using a single +3V supply.

The MAX4714 is pin compatible with the MAX4599 and

is available in a 6-pin SC70 or µDFN package.

9-1982; Rev 1; 5/04 0.8Ω, Low-Voltage, Single-Supply SPDT Analog Switch in SC70 The MAX4714 is a low on-resistance, low-voltage single-pole/double-throw (SPDT) analog switch that operates from a single +1.6V to +3.6V supply. The MAX4714 has break-before-make switching. This device also has fast switching speeds (tON = 18ns, max, tOFF = 12ns, max). When powered from a +3V supply, the MAX4714 features 0.8Ω (max) on-resistance (RON), with 0.18Ω (max) RON matching and flatness. The digital logic input is 1.
