Product details
Overview
The MAX4615CPD from Analog Devices is a quad, normally closed (NC), low-voltage, high-speed SPST CMOS analog switch in a 14-pin plastic DIP package. It operates from +2V to +5.5V, delivers ≤10Ω on-resistance at +5V, matches channels within 1Ω max, and achieves 12ns turn-on/10ns turn-off times. It handles rail-to-rail analog signals (GND to V+) and is used in battery-powered audio routing and low-voltage data-acquisition systems.
For engineers reviewing the MAX4615CPD datasheet, MAX4615CPD pinout, MAX4615CPD application, or MAX4615CPD equivalent, key selection criteria include guaranteed NC configuration, 1Ω max on-resistance matching across all four switches, <6nA off-leakage at +85°C, TTL/CMOS logic compatibility at +5V, and pin compatibility with 74HC4066/MAX4610 for drop-in replacement in legacy designs.
Technical Context
This device implements four independent CMOS transmission-gate-based SPST switches configured as normally closed - each channel conducts when its control input is logic low. The internal architecture ensures matched RON and flat RON over the full signal range (0V to V+), critical for precision multiplexing and sample-and-hold accuracy.
All digital inputs meet TTL/CMOS thresholds (+0.8V low, +2.4V high at +5V supply), enabling direct interface with microcontrollers and logic families without level-shifting. The 14-pin DIP package supports through-hole prototyping and industrial control applications requiring mechanical robustness and thermal stability up to +70°C.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4615CSD | Same electrical specs, but in 14-pin narrow SOIC package - surface-mount, smaller footprint, higher thermal dissipation. | Suitable for space-constrained PCBs and automated assembly; not compatible with through-hole sockets or breadboards. | Select MAX4615CSD for volume production with SMT lines; choose MAX4615CPD for prototyping, repair, or legacy through-hole systems. |
| ADG1414BRUZ | Quad SPST, NC, 1.5Ω RON max at +5V, but requires dual ±15V or single +36V supply - not low-voltage compatible. | Targeted at high-voltage industrial I/O modules; incompatible with battery-powered or 3.3V/5V logic systems. | ADG1414BRUZ is not a functional substitute for MAX4615CPD in low-voltage designs; use only where high-voltage signal routing (>10V) is required. |
Compared with MAX4615CSD, the MAX4615CPD offers identical analog performance but enables manual assembly and socket-based testing; compared with ADG1414BRUZ, it provides true low-voltage operation down to +2V and TTL/CMOS logic compatibility - making it the only viable option for portable, battery-powered, and cost-sensitive embedded systems.

FAQ
What is the maximum supply voltage rating for the MAX4615CPD?
The MAX4615CPD has an absolute maximum supply voltage of +6V, but its specified operational range is +2V to +5.5V. Operating above +5.5V risks exceeding safe internal bias conditions and may degrade RON matching or increase off-leakage. For reliable long-term use, keep V+ ≤ +5.5V, and ensure proper decoupling with a 0.1µF ceramic capacitor placed close to the V+ pin of the MAX4615CPD.
Is the MAX4615CPD pin-compatible with the 74HC4066?
Yes, the MAX4615CPD is fully pin-compatible with the industry-standard 74HC4066 in the 14-pin DIP package. Both share identical pin assignments for COM1–COM4, NC1–NC4, IN1–IN4, V+, and GND. This allows direct replacement without PCB modification - however, the MAX4615CPD improves on the 74HC4066 with lower on-resistance (10Ω vs. ~50Ω), faster switching (12ns vs. ~40ns), and superior leakage performance (<6nA vs. ~100nA at +85°C).
Does the MAX4615CPD support rail-to-rail analog signal operation?
Yes, the MAX4615CPD supports true rail-to-rail analog signal handling from GND to V+. Its CMOS transmission-gate architecture allows signals equal to the supply rails to pass without clipping or distortion - confirmed by specification of VCOM, VNC = 0V to V+ across all operating conditions. This capability is essential for interfacing with full-scale ADCs, DACs, and op-amps operating on the same supply rails as the MAX4615CPD.
What is the typical charge injection of the MAX4615CPD, and why does it matter?
The MAX4615CPD has a typical charge injection of 6.5pC, measured at V+ = +5V and TA = +25°C. Charge injection causes voltage glitches on hold capacitors in sample-and-hold circuits, directly impacting acquisition accuracy and settling time. With 6.5pC and typical hold capacitances (e.g., 100pF), the resulting offset is <65mV - well within tolerance for 12-bit systems. This value is guaranteed across temperature and supply voltage, making the MAX4615CPD suitable for precision measurement applications.
Can the MAX4615CPD operate from a +3.3V supply, and what performance changes occur?
Yes, the MAX4615CPD is fully specified for +3.3V operation. At +3V supply, on-resistance increases to 20Ω (max), RON matching degrades slightly to 1.5Ω (max), and switching times extend to 15ns tON/12ns tOFF. Off-leakage remains <10nA at +85°C. These shifts are fully characterized in the datasheet and do not affect functionality - the MAX4615CPD maintains TTL/CMOS compatibility with adjusted logic thresholds (VIN_H = 2.0V, VIN_L = 0.8V), ensuring reliable interface with 3.3V microcontrollers.
