8-Channel, Dual 4-Channel, Triple 2-Channel Multiplexers
DESCRIPTION
The DG9251, DG9252, and DG9253 are high precision single and dual supply CMOS analog multiplexers. DG9251 is an 8-channel multiplexer, the DG9252 is a dual 4-channel multiplexer, and the DG9253 is a triple 2-channel multiplexer or triple SPDT. Designed to operate from a + 2.7 V to + 16 V single supply or from a ± 2.7 V to ± 5 V dual supplies, the DG9251, DG9252, and DG9253 are fully specified at + 16 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 + 16 V supply. The DG9251, DG9252, and DG9253 are precision multiplexers of low leakage, low charge injection, and lowparasitic capacitance. They conduct equally well in bothdirections, offer rail to rail analog signal handling and can beused both as multiplexers as well as de-multiplexers.The DG9251, DG9252, and DG9253 operating temperature is specified from - 40 °C to + 85 °C and are available in ultra compact 1.8 mm x 2.6 mm miniQFN16 packages.

Notes: a. Signals on SX, DX, or INX exceeding V+ or V- will be clamped by internal diodes. Limit forward diode current to maximum current ratings. b. All leads welded or soldered to PC board. c. Derate 6.6 mW/°C above 70 °C. d. Manual soldering with iron is not recommended for leadless components. The miniQFN-16 is a leadless package. The end of the lead terminal is exposed copper (not plated) as a result of the singulation process in manufacturing. A solder fillet at the exposed copper lip cannot be guaranteed and is not required to ensure adequate bottom side solder interconnection.
