Product details
Overview
MAX13014EKA-T from Maxim Integrated is a dual-channel bidirectional logic-level translator IC enabling 100Mbps data transfer between +1.2V–+3.6V voltage domains. It features independent VL and VCC supplies, active-high EN control, tri-state capability, and operates across –40°C to +85°C. Used in SPI/MICROWIRE interfaces between low-voltage PLDs and 3.3V systems.
For engineers reviewing the MAX13014EKA-T datasheet, MAX13014EKA-T pinout, MAX13014EKA-T application, or MAX13014EKA-T equivalent, this page delivers verified electrical specs, package mapping, real-world timing behavior (tPLH/tPHL ≤6.5ns), supply current under enable/disable states, and validated alternatives for multivoltage interface design.
Technical Context
The MAX13014EKA-T implements a one-shot accelerator output stage architecture that activates only during signal transitions on either I/O VL_ or I/O VCC_, minimizing quiescent current. Each channel supports true bidirectional translation without inversion, with input thresholds set at 1/3 and 2/3 of respective supply rails (VL or VCC).
It requires driver output impedance <25Ω and peak current >20mA for reliable edge acceleration. Load capacitance directly impacts rise/fall time and maximum data rate-guaranteed 100Mbps only when VL ≥1.8V and CIO ≤15pF; drops to 80Mbps at VL = 1.2V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 100Mbps guaranteed when VL ≥1.8V; 80Mbps at VL = 1.2V - defines max usable clock frequency in SPI or data bus applications |
| VCC Range | +1.65V to +3.6V - supports interfacing with 1.8V, 2.5V, 3.3V systems as high-side domain |
| VL Range | +1.2V to (VCC − 0.4V) - enables direct connection to 1.2V ASICs/PLDs without level-shifting pre-stage |
| Supply Current (Active) | IQVCC = 0.1µA typ, IQVL = 10µA typ - ultra-low power for battery-operated portable devices |
| Supply Current (Tri-state) | ITS-VCC = 0.03µA, ITS-VL = 1µA - near-zero standby draw during system sleep or bus arbitration |
| Propagation Delay | tPLH/tPHL ≤6.5ns (VL→VCC), ≤6ns (VCC→VL) - ensures timing closure in high-speed digital interfaces |
| Output Impedance | I/O VL_: 12.5Ω; I/O VCC_: 18.5Ω - matches standard transmission lines and minimizes reflections |
Pinout & Package
MAX13014EKA-T is housed in an 8-pin SOT23 package (package code: -; top mark: AEKB), measuring 3.0mm × 2.6mm × 1.1mm with gull-wing leads. Thermal derating is 9.1mW/°C above +70°C; max continuous power dissipation is 727mW at TA = +70°C.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I/O VL1 | Bidirectional data line referenced to VL; accepts 1.2V logic, outputs scaled to VL domain |
| 2 | I/O VL2 | Second bidirectional VL-referenced I/O; independent of Pin 1, supports dual-signal translation |
| 3 | VL | Low-voltage supply input (+1.2V to VCC−0.4V); must be bypassed with 0.1µF ceramic capacitor |
| 4 | GND | Analog/digital ground reference common to both voltage domains; critical for noise immunity |
| 5 | EN | Active-high enable; drives all I/Os into tri-state when low; pulled up internally only in TSSOP variants |
| 6 | I/O VCC2 | Bidirectional data line referenced to VCC; translates VL-side signals to VCC logic levels |
| 7 | I/O VCC1 | First VCC-referenced I/O; complements Pin 6 for dual-channel operation |
| 8 | VCC | High-voltage supply input (+1.65V to +3.6V); requires local 0.1µF ceramic decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional translation per channel | Enables single-line, non-inverting level shift in either direction (VL↔VCC) without external control logic |
| 100Mbps guaranteed data rate | Validated at VL ≥1.8V and CIO ≤15pF - meets timing requirements for fast SPI clocking (e.g., 50MHz SCLK) |
| Ultra-low tri-state supply current | 0.03µA from VCC and 1µA from VL - extends battery life in always-on portable communication modules |
| One-shot accelerator architecture | Reduces dynamic power by activating output drivers only during signal transitions - cuts switching losses |
| Wide VL operating range down to +1.2V | Directly interfaces with advanced low-power ASICs and FPGA I/O banks without intermediate regulators |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXB0102DCTR | 2-channel, auto-direction sensing, 1.2V–3.6V, 100Mbps; no EN pin; different internal biasing | Requires no external enable control but lacks explicit tri-state mode - unsuitable for shared-bus arbitration | Select when automatic direction detection is preferred and bus contention management is handled elsewhere |
| SN74AVC2T244RSWR | 2-channel, dual-supply, 1.2V–3.6V, 24Mbps max; push-pull outputs; separate OE per channel | Lower speed ceiling limits use in high-frequency SPI; higher drive strength suits heavier capacitive loads | Choose for cost-sensitive industrial designs where 24Mbps suffices and per-channel OE control is required |
Compared with MAX13014EKA-T, TXB0102DCTR offers hands-off direction detection but forfeits deterministic tri-state control, while SN74AVC2T244RSWR trades speed for robustness against 50pF+ loads and per-channel enable granularity - making MAX13014EKA-T optimal for compact, high-speed, enable-governed interfaces.

FAQ
What is the minimum VL voltage supported by MAX13014EKA-T?
MAX13014EKA-T supports VL as low as +1.2V, provided VCC is at least VL + 0.4V (e.g., VL = 1.2V requires VCC ≥ 1.6V). At this minimum, guaranteed data rate drops to 80Mbps; 100Mbps requires VL ≥ 1.8V. The device remains functional even if VL exceeds VCC during power-up sequencing.
Does MAX13014EKA-T require external pull-up resistors on its I/O lines?
No, MAX13014EKA-T integrates internal pull-up (120Ω on I/O VL_, 2.5kΩ on I/O VCC_) and pulldown (75Ω on I/O VL_, 2.5kΩ on I/O VCC_) resistors. External resistors are unnecessary unless specific bus termination or biasing is required beyond the built-in values.
Can MAX13014EKA-T translate I²C signals?
MAX13014EKA-T is not recommended for I²C translation due to its push-pull output architecture and lack of open-drain compatibility. For I²C, Maxim specifies dedicated parts like MAX3372E–MAX3379E or MAX3390E–MAX3393E, which support bidirectional open-drain signaling and bus arbitration.
What is the thermal performance of MAX13014EKA-T in SOT23 package?
MAX13014EKA-T in 8-pin SOT23 has a thermal resistance θJA of 110°C/W. At 727mW max power dissipation and TA = +70°C, junction temperature reaches ~150°C - within absolute max rating. Derate linearly above +70°C at 9.1mW/°C to maintain reliability.
How does the enable (EN) pin behave when left unconnected?
MAX13014EKA-T has no internal EN pull-up or pull-down. Leaving EN floating risks undefined operation or unintended tri-state activation. Always tie EN to VL (for enable) or GND (to disable) using a direct connection or series resistor - never leave it unconnected in production designs.
