DESCRIPTION
The DG2715/2716 are low voltage, single supply, dual SPST
analog switches. Designed for high performance switching of
analog signals, the DG2715/2716 provide low on-resistance
(0.4 @ +2.7 V), fast speed (t
ON
, t
OFF
@ 17 ns and 14 ns)
and the ability to handle signals over the entire analog voltage
range.
When operated on a +3-V supply, control pins are compatible
with 1.8-V digital logic. Additionally, on-resistance flatness and
matching (0.05 and 0.1 ) offer high accuracy between
channels.
Built on Vishay Siliconix's low voltage submicron CMOS
process, the DG2715/16 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.
The DG2715 contains a normally open (NO) switch, and the
DG2716 contains a normally closed switch. An epitaxial layer
prevents latch-up. All switches conduct equally well in both
directions when on, and block up to the power supply level
when off.
As a committed partner to the community and the
environment, Vishay Siliconix manufactures this product with
the lead (Pb)-free device terminations. For analog switching
products manufactured with 100% matte tin device
terminations, the lead (Pb)-free "--E3" suffix is being used as
a designator.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.

Notes:
a.
Room = 25C, Full = as determined by the operating suffix.
b.
The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.

Typical values are for design aid only, not guaranteed nor subject to production testing.
d.
Guarantee by design, nor subjected to production test.
e.
