Product details
Overview
MAX3023EUD+ from Maxim Integrated is a quad-channel bidirectional logic-level translator IC enabling 100Mbps data transfer between 1.2V–1.8V and 1.65V–3.6V voltage domains. It features dual enable inputs (EN/EN), operates over –40°C to +85°C, and supports SPI/MICROWIRE interface translation in portable communication devices and GPS modules.
For engineers reviewing the MAX3023EUD+ datasheet, MAX3023EUD+ pinout, MAX3023EUD+ application, or MAX3023EUD+ equivalent, this page delivers verified electrical specs, TSSOP-14 pin mapping, real-world timing behavior (tEN-VL ≤ 1000ns), tri-state current values (ITS-VL = 55–74µA), and validated alternatives for multivoltage system design.
Technical Context
The MAX3023EUD+ implements a one-shot accelerator output stage architecture that activates only during signal transitions on either VL- or VCC-side I/Os, minimizing static power while achieving guaranteed 100Mbps operation when VL ≥ 1.8V. Its dual enable inputs (EN high-active, EN low-active) allow precise control of tri-state mode across all four bidirectional channels.
Each channel translates signals in both directions (VL ↔ VCC) without inversion, with input thresholds set at 1/3 and 2/3 of respective supply voltages (VIHL = 2/3×VL, VIHC = 2/3×VCC). Output drive strength is defined by one-shot impedance: 12.5Ω on VL side and 18.5Ω on VCC side, ensuring fast edge rates under 15pF load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Data Rate | 100Mbps (guaranteed when VL ≥ 1.8V; drops to 80Mbps if VL < 1.8V) |
| Supply Voltage Range | VCC: +1.65V to +3.6V; VL: +1.2V to (VCC − 0.4V) - enables interfacing low-voltage ASICs with higher-voltage systems |
| Tri-State Supply Current | ITS-VCC = 0.03µA; ITS-VL = 55–74µA (TSSOP package only) - critical for ultra-low-power sleep modes |
| Propagation Delay | tEN-VL ≤ 1000ns, tEN-VCC ≤ 1000ns - defines worst-case latency after enable assertion |
| Output Impedance | 12.5Ω (VL side), 18.5Ω (VCC side) - ensures sub-4ns rise/fall times into 15pF loads |
| Input Thresholds | VIHL/VILL = 2/3×VL / 1/3×VL; VIHC/VILC = 2/3×VCC / 1/3×VCC - compatible with standard CMOS logic families |
| Operating Temperature | –40°C to +85°C - qualified for industrial and portable consumer applications |
Pinout & Package
MAX3023EUD+ is housed in a 14-pin TSSOP package (4.4mm width, 1.0mm max height), optimized for space-constrained PCB layouts in portable electronics. Pin assignments are fully defined per Maxim's official pin description table and confirmed for the TSSOP variant.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXB0104RUTR | Auto-direction sensing; no enable pins; 1.2V–3.6V VCCA/VCCB; max 100Mbps only at 3.3V/1.8V | Requires no external enable control but lacks independent tri-state gating per channel | Select when automatic direction detection is preferred and board space allows larger 14-pin UQFN package |
| SN74AVC4T245PW | Direction-controlled (DIR pin); 1.2V–3.6V; guaranteed 100Mbps only with 15pF load and 2.5V supplies | Unidirectional per channel unless externally wired; requires additional GPIO for DIR control | Select when deterministic direction control is needed and system can dedicate GPIOs for DIR signals |
Compared with TXB0104RUTR and SN74AVC4T245PW, the MAX3023EUD+ uniquely provides dual independent enable inputs for precise per-channel power gating, guaranteed 100Mbps operation down to VL = 1.8V, and fixed bidirectional operation without direction-sensing overhead or external control lines.

FAQ
What is the maximum guaranteed data rate for MAX3023EUD+?
The MAX3023EUD+ guarantees 100Mbps data transfer when VL ≥ 1.8V and capacitive load ≤15pF. At VL < 1.8V, the guaranteed rate drops to 80Mbps. These values are production-tested and specified in the official Maxim datasheet under Timing Characteristics.
Does MAX3023EUD+ support true bidirectional translation without external direction control?
Yes, the MAX3023EUD+ performs automatic bidirectional level translation on each of its four channels without requiring a direction-control signal. Its one-shot accelerator architecture detects transitions on either side and drives the opposite side accordingly - a core feature confirmed in the Detailed Description section of the datasheet.
What are the supply current values for MAX3023EUD+ in tri-state mode?
In tri-state mode, the MAX3023EUD+ draws 0.03µA from VCC and 55–74µA from VL (TSSOP-specific spec). These ultra-low values are measured at TA = +25°C with EN = 0 and EN = VL, and are critical for battery-operated applications where standby power must be minimized.
Can MAX3023EUD+ operate with VL = 1.2V and VCC = 3.3V simultaneously?
Yes - the MAX3023EUD+ explicitly supports VL as low as +1.2V and VCC as high as +3.6V, provided VL ≤ VCC − 0.4V. With VCC = 3.3V, VL may range from +1.2V to +2.9V, making it suitable for interfacing 1.2V ASICs with 3.3V peripherals.
What is the purpose of the dual enable inputs (EN and EN) on MAX3023EUD+?
The EN (active-high) and EN (active-low) inputs on the MAX3023EUD+ provide redundant, complementary control of tri-state mode. Driving EN = VL and EN = GND enables normal operation; pulling either EN low or EN high forces all I/Os into high-impedance state - enhancing system-level fault tolerance and power sequencing robustness.
