The MAX336/MAX337 are monolithic, CMOS analog multiplexers (muxes) that can be used as either a mux or a demux. They have low on-resistance, fast transition time, and low leakage current. They operate from a single supply or dual supplies and are pin-compatible upgrades for the DG506 and DG507. They are suitable for precision data acquisition, precision signal routing, and test equipment.
The MAX336 (16‑channel) and MAX337 (dual 8‑channel) are monolithic CMOS analog multiplexers that connect one of multiple inputs to a common output using a binary address. They support bidirectional signal handling, low on‑resistance, and extremely low leakage currents, making them suitable for precision data‑acquisition and signal‑routing applications.
The devices operate from a single +4.5 V to +30 V supply or from dual ±4.5 V to ±20 V supplies, feature TTL‑compatible control inputs, and provide >2000 V ESD protection. Typical performance includes <400 Ω on‑resistance, <500 ns transition time, and 3.5 pC typical charge injection. Pin‑compatible upgrades are available for DG506/DG507 parts.
