DESCRIPTION
The DG9408/9409 uses BiCMOS wafer fabrication technology that allows the DG9408/9409 to operate on single and dual supplies. Single supply voltage ranges from 3- to 12-V while dual supply operation is recommended with "3 to "6 V. The DG9408 is an 8-channel single-ended analog multiplexer designed to connect one of eight inputs to a common output as determined by a 3-bit binary address (A0, A1, A2). The DG9409 is a dual 4-channel differential analog multiplexer designed to connect one of four differential inputs to a common dual output as determined by its 2-bit binary address (A0, A1). Break-before-make switching action to protect against momentary crosstalk between adjacent channels.

Notes a. Leakage parameters are guaranteed by worst case test condition and not subject to production test. b. Room = 25_C, Full = as determined by the operating temperature suffix. c. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet. d. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing. e. Guaranteed by design, not subject to production test. f. VIN = input voltage to perform proper function. g. DrDON = rDON Max - rDON Min. h. Worst case isolation occurs on Channel 4 do to proximity to the drain pin. i. rDON flatness is measured as the difference between the minimum and maximum measured values across a defined Analog signal.
