The MAX336/MAX337 are monolithic, CMOS analog multiplexers (muxes). The 16-channel MAX336 is designed to connect one of 16 inputs to a common out- put by control of a 4-bit binary address. The dual, 8-channel MAX337 is designed to connect one of eight inputs to a common output by control of a 3-bit binary address. Both devices can be used as either a mux or a demux.
The MAX336 and MAX337 are monolithic CMOS analog multiplexers offering 16‑channel (MAX336) or dual 8‑channel (MAX337) operation with very low off‑leakage and charge injection. They can be used as multiplexers or demultiplexers and support bidirectional signal flow.
The devices operate from a single‑supply range of +4.5 V to +30 V or dual‑supply range of +4.5 V to +20 V, feature >2000 V ESD protection, and provide typical on‑resistance of about 500 Ω. Pin‑compatible packages include DIP, SO, SSOP and CERDIP variants.
| Supply Voltage (single) | +4.5 V to +30 V |
|---|---|
| Supply Voltage (dual) | +4.5 V to +20 V |
| Off‑Leakage Current (typical) | <20 pA at +25 °C |
| Charge Injection (typical) | 3.5 pC |
| ESD Protection | >2000 V |
They operate from a single‑supply range of +4.5 V to +30 V or from dual supplies of +4.5 V to +20 V.
The typical off‑leakage current is less than 20 pA at +25 °C.
They provide greater than 2000 V ESD protection per IEC 607 standard.
