DESCRIPTION
The DG2018 and DG2019 are low voltage, single supply
analog switches. The DG2018 is a dual
double-pole/double-throw (DPDT) with two control inputs that
each controls a pair of single-pole/double-throw (SPDT). The
DG2019 uses one control pin to operate four independent
SPDT switches.
When operated on a +3-V supply, the DG2018’s control pins
are compatible with 1.8-V digital logic. The DG2019 has an
available feature of a V_L pin that allows a 1.0-V threshold for the
control pin when V_L is powered with 1.5 V.
Built on Vishay Siliconix’s low voltage submicron CMOS
process, the DG2018 and DG2019 are ideal for high
performance switching of analog signals; providing low
on-resistance (6 W @ +2.7 V), fast speed (T_on, T_off @ 42 ns
and 16 ns), and a bandwidth that exceeds 150 MHz.
The DG2018 and DG2019 were designed to offer solutions
that extend beyond audio/video functions, to providing the
performance required for today’s demanding mixed-signal
switching in portable applications.
An epitaxial layer prevents latch-up. Brake-before-make is
guaranteed for all SPDT’s. All switches conduct equally well in
both directions when on, and blocks up to the power supply
level when off.
