Product details
Overview
MAX14595EWA+T from Maxim Integrated is a dual-channel, bidirectional logic-level translator optimized for I²C and MDIO buses in portable systems. It supports 0.9V to 3.6V on the VL side and 1.65V to 5.5V on the VCC side, delivers ≤17Ω RON, achieves ≤8MHz push-pull data rates, and consumes only 7µA (VCC) / 3µA (VL) in active mode - enabling battery-powered sensor hubs and low-power microcontroller interfaces.
For engineers reviewing the MAX14595EWA+T datasheet, MAX14595EWA+T pinout, MAX14595EWA+T application, or MAX14595EWA+T equivalent, this page provides verified electrical specs, WLP package details, thermal shutdown behavior, TS-controlled three-state operation, and I²C/MDIO timing compliance - all confirmed against Maxim's official 2011 datasheet (Rev 0).
Technical Context
The MAX14595EWA+T implements two independent bidirectional transmission gates with integrated accelerator circuitry to reduce rise/fall times below 22ns (tR/tF) under 15pF load. Its TS input enables high-impedance shutdown with sub-1µA supply current and automatic pullup resistor activation when only one supply (VL or VCC) is powered.
It meets I²C standard/fast/high-speed timing requirements and MDIO open-drain operation above 4MHz using internal 3–12kΩ pullups - no external resistors needed during single-supply operation. Thermal shutdown triggers at +150°C with 10°C hysteresis, protecting against sustained overloads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VL Range | +0.9V to min(VCC + 0.3V, +3.6V): Enables direct interface with 0.9V I/O domains like modern ultra-low-power MCUs. |
| VCC Range | +1.65V to +5.5V: Supports legacy 3.3V/5V peripherals while maintaining compatibility with newer 1.8V systems. |
| Max Data Rate | 8MHz (push-pull), 4MHz (open-drain): Meets I²C fast-mode plus and MDIO timing with ≤100pF bus capacitance. |
| RON (max) | 17Ω: Minimizes voltage drop and signal distortion in high-speed open-drain configurations. |
| ICC / IL | 7µA / 3µA typical: Extends battery life in always-on sensor nodes and wearable devices. |
| Thermal Shutdown | +150°C (typ), 10°C hysteresis: Prevents permanent damage during transient overloads without external protection circuitry. |
| TS Shutdown Current | ≤1µA (VCC or VL): Ensures near-zero power draw during system sleep states. |
Pinout & Package
MAX14595EWA+T uses an 8-bump Wafer-Level Package (WLP), 0.4mm pitch, 0.8mm × 1.6mm footprint, suitable for space-constrained portable PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VL (Bump A1) | Low-voltage logic supply | Reference for IOVL1/IOVL2; must be bypassed with 0.1µF ceramic capacitor close to the bump. |
| IOVL2 (Bump A2) | Bidirectional I/O channel 2 (VL side) | Connects to 0.9–3.6V domain; supports open-drain or push-pull signaling with internal acceleration. |
| IOVL1 (Bump A3) | Bidirectional I/O channel 1 (VL side) | Independent of IOVL2; shares same VL rail and timing characteristics. |
| TS (Bump A4) | Active-high three-state control | Drives device into high-Z shutdown when low; enables dynamic power gating in multi-rail systems. |
| VCC (Bump B1) | High-voltage power supply | Reference for IOVCC1/IOVCC2; requires 1µF ceramic bypass capacitor adjacent to bump. |
| IOVCC2 (Bump B2) | Bidirectional I/O channel 2 (VCC side) | Translates signals to/from 1.65–5.5V domain; internal pullup enabled when VCC is powered and TS = high. |
| IOVCC1 (Bump B3) | Bidirectional I/O channel 1 (VCC side) | Electrically isolated from IOVCC2; identical performance and biasing requirements. |
| GND (Bump B4) | Common ground reference | Single ground connection for both VL and VCC domains; critical for noise immunity in mixed-voltage routing. |
Key Features
| Feature | Design Value |
|---|---|
| Auto-activated internal pullups | 3–12kΩ per I/O, enabled only when corresponding supply (VL or VCC) is present and TS = high - eliminates external resistors in asymmetric power-up scenarios. |
| Accelerated edge response | Rise/fall times as low as 2.8ns (IOVL_ fall) and 3ns (IOVCC_ propagation) enable reliable 8MHz push-pull signaling without external buffers. |
| Asymmetric voltage tolerance | IOVL pins tolerate up to (VL + 0.5V); IOVCC pins tolerate up to (VCC + 0.5V) - prevents latch-up during supply sequencing mismatches. |
| Thermal protection with hysteresis | Shuts down at +150°C (typ), resumes at +140°C (typ) - avoids oscillation during thermal transients and ensures safe recovery. |
| Shutdown leakage control | <1µA total supply current in TS = low state - meets stringent energy budget targets for IoT endpoint sleep modes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional logic-level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0102DCTT | Higher ICC (20µA active), no thermal shutdown, fixed 1.65–3.6V VCC range, no TS pin - relies on external enable. | Best suited for cost-sensitive consumer electronics where thermal margin is not critical and supply rails are tightly constrained. | Select TXS0102DCTT only if VCC stays within 1.65–3.6V and thermal protection is handled at system level. |
| PCA9306DCUR | Passive FET-based design, no internal pullups, no TS control, 1.2–3.6V VREF1/VREF2 limits, higher RON (~30Ω). | Requires external pullups and careful supply sequencing; used in legacy I²C designs where simplicity outweighs power/performance needs. | Choose PCA9306DCUR only when board space allows external 4.7kΩ pullups and system-level power sequencing is fully controlled. |
Compared with TXS0102DCTT and PCA9306DCUR, the MAX14595EWA+T uniquely combines ultra-low supply current (7µA/3µA), integrated thermal shutdown, TS-controlled three-state, and auto-selective internal pullups - making it the only option qualified for battery-critical, thermally unmanaged, and asymmetric-power industrial portable designs.

FAQ
What is the maximum capacitive load the MAX14595EWA+T can drive while maintaining 8MHz push-pull operation?
The MAX14595EWA+T maintains ≤8MHz push-pull data rate with ≤100pF total capacitive load on either IOVL or IOVCC lines, as validated in Figures 1 and 3 of the datasheet. At 100pF, tR/tF remains ≤22ns and propagation delay stays under 19ns (rising) and 9ns (falling) - ensuring timing margin for I²C fast-mode plus compliance. Exceeding 100pF degrades edge speed and may cause setup/hold violations.
Does the MAX14595EWA+T require external pullup resistors for I²C open-drain operation?
No - the MAX14595EWA+T integrates 3–12kΩ pullup resistors on both IOVL and IOVCC sides, activated automatically when the corresponding supply (VL or VCC) is powered and TS = high. External pullups are optional and only recommended for high-speed (>4MHz) open-drain operation where tighter rise-time control is needed beyond internal resistor capability.
Can the MAX14595EWA+T operate with VL greater than VCC?
Yes - VL may transiently exceed VCC during startup/shutdown (per Note 3), but normal bidirectional translation requires VL ≤ VCC. The device disables translation when VL > VCC to prevent backfeeding; it resumes only after VL drops below VCC − 0.4V (VIHC threshold). This protects downstream 1.65V logic from overvoltage.
How does the TS pin affect internal pullup resistor behavior in the MAX14595EWA+T?
When TS = high, internal pullups activate only on the side (VL or VCC) where supply voltage is present and regulated - e.g., if only VL is powered, only IOVL1/IOVL2 pullups engage. When TS = low, all pullups disconnect and both I/O channels enter high-impedance state, drawing <1µA total supply current. This enables dynamic power gating without external logic.
Is the MAX14595EWA+T RoHS-compliant and lead-free?
Yes - the "+T" suffix in MAX14595EWA+T denotes a lead(Pb)-free and RoHS-compliant 8-bump WLP package, per Maxim's Ordering Information table (page 10 of the datasheet). The top mark "AAE" and package code "W80A1+1" confirm full compliance with EU RoHS Directive 2011/65/EU and JEDEC J-STD-020 reflow standards.
