Power Down Fault Protected,
1.8 V to 5.5 V, 2.5 , 4-Channel (4:1) Multiplexer
DESCRIPTION
The DG2034E is a four-channel multiplexer that operates
with a single 1.8 V to 5.5 V power supply. It features power
down fault protection that prevents excessive current flow
when V+ is to ground.
The device’s low power dissipation and wide voltage range
make it ideal for use in battery powered products. The ultra
low capacitance and charge injection of the switch make it
an ideal solution for data acquisition and sample and hold
applications, where low glitch and fast settling are required.
Low switch resistance and fast switching speeds, together
with high signal bandwidth, make the DG2034E suitable for
video signal switching.
The DG2034E switches one of four inputs to a common
output as determined by the 3-bit binary address lines: A0,
A1, and EN. Each switch conducts equally well in both
directions when on, blocks input voltages up to the supply
level when off, and exhibits break before make switching
action.
The device’s high ESD and latch-up current capability make
it more reliable in designs where the part sits close to the
interface.
The DG2034E is available in MSOP10 and QFN12
3 mm x 3 mm packages.
