General Description
The MAX328/MA329 are monolithic CMOS analog multiplexers. The MAX328 is a single-ended, 1-of-8 device, and the MAX329 is a differential, 2-of-8 device.
Designed to provide the lowest possible on- and off-leakages, these multiplexers switch signals from high source impedance, providing the mux operates into a high-input-impedance op amp or A/D converter. The MAX328/MAX329 are pin-for-pin replacements for the popular DG508/DG509 in these applications

FEATUREs
♦ Ultra-Low Off- and On-Leakage: 1pA Typ
♦ Bidirectional Operation (Use as Mux or Demux)
♦ TTL and CMOS Logic Compatibility
♦ Analog-Signal Range Includes Power-Supply Rails
♦ Switching Speeds Less Than 1.5µs
♦ Pin Compatible with DG508/DG509 and MAX358/MAX359
♦ Latchup Proof Construction
