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.
