Analog Devices Inc./Maxim Integrated MAX4606CPE

Overview

MAX4606CPE from Maxim Integrated is a quad SPST CMOS analog switch with two normally open (NO) and two normally closed (NC) channels, 5Ω max on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and rail-to-rail signal handling-ideal for reed relay replacement in PBX systems and test equipment.

For engineers reviewing the MAX4606CPE datasheet, MAX4606CPE pinout, MAX4606CPE application, or MAX4606CPE equivalent, key selection criteria include guaranteed R_ON match (0.5Ω max), off-leakage current ≤2.5nA at +85°C, TTL/CMOS-compatible logic thresholds, and 16-pin plastic DIP package compatibility with legacy through-hole layouts.

Technical Context

The MAX4606CPE implements four independent SPST switches in a single monolithic CMOS process, with dedicated NO and NC paths per channel pair. Its control architecture uses buffered digital inputs referenced to VL (logic supply), enabling reliable switching across wide analog voltage ranges without level-shifting.

Each switch supports bidirectional rail-to-rail analog signals up to ±20V (dual) or +36V (single), with matched on-resistance (ΔR_ON ≤0.5Ω) and flat on-resistance (≤0.5Ω variation over full signal range), minimizing harmonic distortion in audio-signal routing and precision instrumentation.

Key Specifications

Pinout & Package

FAQ

What is the maximum supply voltage rating for MAX4606CPE?

The MAX4606CPE supports a single analog supply up to +36V or dual supplies from ±4.5V to ±20V. Absolute maximum ratings specify V+ to GND ≤ +44V and V− to GND ≥ −44V, but continuous operation beyond ±20V or +36V violates the datasheet's specified operating range and may compromise R_ON flatness and leakage performance. Always observe the recommended supply limits for guaranteed specifications in the MAX4606CPE datasheet.

Does MAX4606CPE support rail-to-rail analog signals?

Yes, the MAX4606CPE supports rail-to-rail analog signal handling - meaning signals from V− to V+ can pass through the switch without clipping or distortion. This is confirmed in the General Description and Electrical Characteristics tables, where input voltage range is specified as (V− − 0.3V) to (V+ + 0.3V) with internal clamping diodes. The feature enables direct interfacing with op-amps and sensors operating at full supply rails, a core design requirement validated for the MAX4606CPE across its entire temperature range.

How many normally open and normally closed switches does MAX4606CPE contain?

The MAX4606CPE contains exactly two normally open (NO) switches and two normally closed (NC) switches - a hybrid configuration distinct from the all-NO MAX4605 and all-NC MAX4604. Pin assignments confirm NO functionality on pins 11 and 14 (NO1, NO4), and NC functionality on pins 3 and 6 (NC1, NC2), as shown in the functional diagram and truth table for MAX4606 in the official datasheet. This 2×NO/2×NC topology is fixed for the MAX4606CPE and cannot be reconfigured.

What is the logic supply (VL) voltage range for MAX4606CPE?

The VL pin on the MAX4606CPE accepts a logic supply from 3V to 5V, independent of the analog supply rails. This allows clean TTL/CMOS-compatible switching even when V+ and V− operate at ±15V or +24V. The datasheet specifies VL to GND as (DGND − 0.3V) to (V+ + 0.3V), but functional operation with guaranteed input thresholds (0.8V low, 2.4V high) is only assured within 3V–5V. Using VL outside this range may cause undefined logic behavior or increased input current in the MAX4606CPE.

Is MAX4606CPE pin-compatible with other variants like MAX4606CSE?

Yes, the MAX4606CPE (16-pin plastic DIP) and MAX4606CSE (16-pin narrow SO) share identical pinouts and electrical specifications - differing only in package type and thermal characteristics. Both use the same die and functional pin mapping: IN1–IN4 on pins 1/8/9/16, COM1–COM4 on 2/7/10/15, NC1/NC2 on 3/6, NO1/NO4 on 11/14, V+ on 13, V− on 4, GND on 5, and VL on 12. No PCB redesign is needed when migrating between these packages, though layout must accommodate DIP vs. SO footprint differences in the MAX4606CPE implementation.
