Product details
Overview
The MAX4583LETE from Maxim Integrated is a low-voltage CMOS analog IC configured as three independent single-pole/double-throw (SPDT) switches, operating from +2V to +12V single supply, with rail-to-rail signal handling, 2nA off-leakage at +25°C, 80Ω max on-resistance at +12V, and pin-compatible with industry-standard 74HC4053 and MAX4053 for audio/video routing and data-acquisition systems.
For engineers reviewing the MAX4583LETE datasheet, MAX4583LETE pinout, MAX4583LETE application, or MAX4583LETE equivalent, this device supports high-isolation analog switching in compact TQFN-EP packaging with TTL/CMOS logic compatibility, low crosstalk (-96dB), and guaranteed on-resistance matching (±4Ω) - critical for precision multiplexing in DSL modems and communications circuits.
Technical Context
The MAX4583LETE implements three fully independent SPDT analog switches, each with break-before-make timing (20ns), charge injection ≤0.5pC, and bidirectional signal flow. Digital control uses address inputs A/B/C and ENABLE, with logic thresholds fixed at 0.8V (VIL) and 2.0V (VIH) across full temperature range.
All switches share a common VCC and GND, with internal ESD diodes clamping analog pins to VCC/GND. The exposed pad (EP) must be externally connected to VCC for thermal and electrical integrity. No internal level-shifting or biasing is required for rail-to-rail operation.

Use Value: 2nA off-leakage preserves DC-coupled bias networks; 80Ω RON minimizes insertion loss (<0.4dB at 10kΩ load); -90dB off-isolation prevents audible crosstalk between stereo channels. | Use Scenario: Selecting between upstream/downstream filter banks and line driver/receiver paths in ADSL/VDSL modem PHY layer. IC Role / Device Role / Timing Role: Analog switch matrix isolating high-frequency analog sections during mode transitions, controlled via FPGA I/O with 0.8V–2.0V logic thresholds. Use Value: -90dB off-isolation suppresses 1–30MHz interference between transmit/receive paths; 0.5pC charge injection prevents baseline shift in high-resolution ADC sampling stages. |
| Data-Acquisition Multiplexing | Communications Circuit Protection |
Use Scenario: Scanning 6-channel thermocouple or RTD inputs into a single precision ADC in industrial PLC analog input modules. IC Role / Device Role / Timing Role: Three SPDTs configure differential input pairs (e.g., CH0+/CH0−, CH1+/CH1−) while maintaining matched RON for common-mode rejection. Use Value: ±4Ω RON match ensures <0.01% gain error between channels; 2nA leakage avoids offset drift in high-impedance sensor bridges; 4mm × 4mm QFN saves >60% board area vs. SOIC alternatives. | Use Scenario: Isolating sensitive RF transceiver ICs from antenna tuning networks during power-down or fault conditions in cellular IoT modules. IC Role / Device Role / Timing Role: Fail-safe analog switch disconnecting RF paths when ENABLE is deasserted, leveraging break-before-make (20ns) to prevent short-circuited antenna states. Use Value: 20ns BBM prevents momentary VSWR collapse; +2V min supply allows operation from backup coin-cell during main power loss; EP-connected VCC improves RF grounding integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4053ESE+ | Same pinout, 100Ω max RON at +15V, -75dB off-isolation, no exposed pad | Lower isolation and higher RON limit use in high-fidelity audio or broadband comms | Select MAX4583LETE for improved isolation (-90dB), lower RON (80Ω), and thermal performance via EP. |
| TMUX1308RSVR | 8-channel mux (not SPDT), 5V-only supply, 1.8V logic compatible, 5.5Ω RON | Not functionally equivalent - lacks independent SPDT topology and dual-path isolation capability | Use only if system requires 8:1 multiplexing instead of three discrete SPDTs; not a drop-in replacement. |
Compared with MAX4053ESE+, the MAX4583LETE delivers 15dB better off-isolation and 20Ω lower on-resistance, directly improving SNR in audio routing and reducing insertion loss in DSL line drivers; versus TMUX1308RSVR, it provides true SPDT functionality essential for fail-safe path isolation in communications protection circuits.

FAQ
What is the maximum supply voltage rating for the MAX4583LETE?
The MAX4583LETE has an absolute maximum supply voltage of +13V, but its specified operational range is +2V to +12V. Operation at +12V ensures guaranteed performance for on-resistance (80Ω max), leakage current (±2nA), and switching speed (100ns tOFF). Exceeding +12V may degrade parametric limits or reliability, and is not recommended for production designs using the MAX4583LETE.
Does the MAX4583LETE support bidirectional analog signal flow?
Yes, the MAX4583LETE supports fully bidirectional analog signal flow - any pin can serve as input or output. This is explicitly confirmed in the datasheet's "Detailed Description" section: "Input and output pins are identical and interchangeable. Any may be considered an input or output; signals pass equally well in both directions." This capability is inherent to the CMOS transmission-gate architecture used in the MAX4583LETE.
How should the exposed pad (EP) on the MAX4583LETE be connected?
The exposed pad (EP) on the MAX4583LETE must be externally connected to VCC. Per the Pin Description table and Package Information, the EP is electrically tied to VCC internally and serves as a thermal and electrical reference. Soldering the EP to a VCC copper pour improves thermal dissipation by >50% and reduces ground bounce in high-speed switching - a mandatory step for reliable operation of the MAX4583LETE at full temperature range.
Is the MAX4583LETE pin-compatible with the 74HC4053?
Yes, the MAX4583LETE is pin-compatible with the industry-standard 74HC4053, as stated in the datasheet's Features section: "Pin Compatible with Industry-Standard 74HC4051/74HC4052/74HC4053 and MAX4051/MAX4052/MAX4053." This applies to the 16-pin TQFN-EP footprint, including identical pin functions for X/Y/Z commons, NO/NC terminals, address lines A/B/C, ENABLE, VCC, and GND - enabling direct substitution in existing 74HC4053 layouts using the MAX4583LETE.
What is the guaranteed on-resistance match between SPDT channels in the MAX4583LETE?
The MAX4583LETE guarantees an on-resistance match of ±4Ω between its three SPDT channels, measured at +25°C with VCC = 11.4V and 1mA test current. This specification (ΔRON) ensures consistent gain and signal integrity across independently switched paths - critical for differential signaling and multi-channel calibration routines where channel-to-channel tracking is required in systems using the MAX4583LETE.
