Analog Devices Inc./Maxim Integrated MAX4669CSE+T

Overview

MAX4669CSE+T from Maxim Integrated is a dual SPST CMOS analog switch with one normally closed (NC) and one normally open (NO) channel, guaranteeing break-before-make operation. It delivers 2.5Ω max on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and rail-to-rail analog signal handling up to ±20V - ideal for reed relay replacement in automated test equipment and audio-signal routing.

For engineers reviewing the MAX4669CSE+T datasheet, MAX4669CSE+T pinout, MAX4669CSE+T application, or MAX4669CSE+T equivalent, key selection criteria include guaranteed break-before-make timing (5–30 ns), matched on-resistance (≤0.4Ω between channels), low off-leakage (≤0.5nA at +85°C), and TTL/CMOS-compatible logic thresholds at ±15V or +12V supplies.

Technical Context

The MAX4669CSE+T implements a complementary MOSFET switch architecture with integrated level-shifting logic to support wide analog voltage ranges while maintaining precise control over switching sequence. Its break-before-make behavior is hardware-guaranteed via internal timing circuitry, eliminating external sequencing components.

It supports dual- and single-supply configurations without performance degradation: on-resistance flatness remains ≤0.5Ω over full signal range (±10V), and dynamic parameters - including turn-on time (400 ns typ), turn-off time (300 ns typ), and charge injection (450 pC typ) - are characterized across -40°C to +85°C for industrial reliability.

Key Specifications

Pinout & Package

Manufacturer

Maxim Integrated (now part of Analog Devices) designs precision analog, mixed-signal, and power management ICs for industrial, automotive, and communications markets.

The MAX4667/MAX4668/MAX4669 family was engineered specifically for high-reliability analog signal routing where mechanical relay limitations - speed, lifetime, and power - demand solid-state alternatives with guaranteed switching behavior.

FAQ

What is the guaranteed break-before-make timing specification for MAX4669CSE+T?

The MAX4669CSE+T guarantees a hardware-enforced break-before-make delay of 5 ns minimum to 30 ns maximum between its NO and NC channels. This parameter is tested and specified across the full operating temperature range (-40°C to +85°C) and ensures no overlap in conduction during switching - a critical requirement for preventing shorts in multiplexer and signal-routing applications. The MAX4669CSE+T achieves this without external timing components.

Can MAX4669CSE+T operate from a single +12V supply?

Yes, MAX4669CSE+T supports single-supply operation from +4.5V to +36V. When using +12V, connect V− to GND, set VL to +5V, and ensure logic inputs meet TTL/CMOS thresholds (V_{IN_H} ≥ 2.4V, V_{IN_L} ≤ 0.8V). On-resistance increases slightly to 4Ω max under these conditions, but all other specifications - including break-before-make, leakage, and bandwidth - remain fully valid. The MAX4669CSE+T is explicitly characterized for +12V single-supply use in its datasheet.

What is the maximum analog signal voltage range supported by MAX4669CSE+T?

The MAX4669CSE+T supports rail-to-rail analog signals from V− to V+, with absolute maximum ratings of ±44V across V+ and V−. In standard dual-supply operation (±15V), it handles ±10V signals with guaranteed 0.5Ω on-resistance flatness. For single-supply use (+12V), the analog range extends from GND to +12V. The MAX4669CSE+T's internal protection diodes clamp signals beyond rails, but sustained overvoltage requires external limiting per the datasheet's Figure 1 guidance.

How does MAX4669CSE+T compare to MAX4667CSE+T and MAX4668CSE+T?

The MAX4669CSE+T differs from MAX4667CSE+T (dual NC) and MAX4668CSE+T (dual NO) solely in switch configuration: it integrates one NC and one NO channel with guaranteed break-before-make timing - a feature absent in the other two variants. All three share identical electrical specs: 2.5Ω R_ON, ±20V analog range, and pinout compatibility. The MAX4669CSE+T is selected exclusively when sequential, non-overlapping channel switching is required - such as in analog multiplexers or safety-critical signal path selection.

Is MAX4669CSE+T RoHS-compliant and lead-free?

Yes, MAX4669CSE+T is RoHS-compliant and lead-free. The "+T" suffix denotes tape-and-reel packaging with lead-free (Pb-free) termination finish, meeting JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) requirements. The device undergoes 100% solderability testing and complies with Analog Devices' current environmental policy, including exemption 7a for lead in high-melting-temperature solder alloys where applicable. Full compliance documentation is available under Analog Devices' product change notification (PCN) archive for MAX4669.
