DG9451, DG9453
Vishay Siliconix
8-Channel, Dual 4-Channel, Triple 2-Channel Multiplexers
DESCRIPTION
The DG9451, and DG9453 are high precision single and
dual supply CMOS analog multiplexers. DG9451 is an
8-channel multiplexer, and the DG9453 is a triple 2-channel
multiplexer or triple SPDT.
Designed to operate from a + 2.7 V to + 12 V single supply
or from a ± 2.5 V to ± 5 V dual supplies, the DG9451, and
DG9453 are fully specified at + 12 V, + 5 V and ± 5 V. All
control logic inputs have guaranteed 1.4 V high limit when
operating from + 5 V or ± 5 V supplies and 1.65 V when
operating from a + 12 V supply.
The DG9451, and DG9453 are precision multiplexers of low
leakage, low charge injection, and low parasitic capacitance.
They conduct equally well in both directions, offer rail to rail
analog signal handling and can be used both as multiplexers
as well as de-multiplexers.
The DG9451, and DG9453 operating temperature is
specified from - 40 °C to + 85 °C and are available in 16 pin
TSSOP and the ultra compact 1.8 mm x 2.6 mm miniQFN16
packages.
