Dual SPDT Analog Switch DESCRIPTION The DG9236 is a CMOS, dual SPDT analog switch designed to operate from = 2.7 V to = 6 V max. operating, single supply. All control logic inputs have a guaranteed.8 V logic high threshold when operation from a + 6 V power supply. This makes the DG9236 ideally suited to interface directly with low voltage micro-processor control signals. Processed with high density CMOS technology, the DG9236 while providing ultra low parasitic capacitance of 2 pf for CS (OFF) and 8.4 pf for CD (ON). Other performance features are: 3 db bandwidth, 8 MHz, - 7 db crosstalk and 62 db off isolation at MHz frequency. Key applications for the DG9236 are logic level translation, pulse generator, and high speed or low noise signal switching in precision instrumentations and portable device designs. The operation temperature range is specified from - 4 C to + 85 C. The DG9236 is available in space saving.4 mm x.8 mm miniqfn package. As a committed partner to the community and the environment, manufactures this product with lead (Pb)-free device termination. The miniqfn- package has a nickel-palladium-gold device termination and is represented by the lead (Pb)-free -E4 suffix to the ordering part number. The nickel-palladium-gold device terminations meet all JEDEC standards for reflow and MSL rating. FEATURES Leakage current <.5 na max. at 85 C Low switch capacitance (C soff, 2 pf typ.)
