Analog Devices Inc./Maxim Integrated MAX3006EUP+

Overview

MAX3006EUP+ from Maxim Integrated is an 8-channel unidirectional logic-level translator designed for voltage-domain bridging between low-voltage ASICs/PLDs (VL = +1.2V to +5.5V) and higher-voltage systems (VCC = +1.65V to +5.5V). It guarantees 20Mbps data rate, supports ±15kV HBM ESD protection on I/O VCC lines, features EN-controlled shutdown with <2µA supply current, and operates across –40°C to +85°C in a 20-pin TSSOP package. Used in portable POS systems and smart card readers requiring robust signal integrity.

For engineers reviewing the MAX3006EUP+ datasheet, MAX3006EUP+ pinout, MAX3006EUP+ application, or MAX3006EUP+ equivalent, this page delivers verified electrical specifications, bidirectional/unidirectional mode clarification, EN pin behavior per channel group, real-world timing performance at 20Mbps, and validated alternatives for multivoltage interface design.

Technical Context

The MAX3006EUP+ implements unidirectional level translation (VL → VCC or VCC → VL per channel pair), distinct from the bidirectional MAX3000E/MAX3001E/MAX3002/MAX3003. Its EN pin enables selective channel grouping: when EN is low, IVCC1–IVCC2 and OVCC3–OVCC8 enter three-state, while OVL1–OVL2 and IVL3–IVL8 activate 6kΩ pulldowns - enabling partial bus isolation without full shutdown.

It uses a one-shot accelerator output stage optimized for 20Mbps operation under 15pF load at +2.5V ≤ VL ≤ VCC ≤ +3.3V, achieving 8.5ns typical rise/fall times and 8.5ns propagation delay. Unlike MAX3000E (230kbps) or MAX3001E (4Mbps), it does not support true bidirectional operation and lacks directional-pin-free architecture.

Key Specifications

Pinout & Package

MAX3006EUP+ is housed in a 20-pin TSSOP (Thin Shrink Small Outline Package) with exposed pad (EP), requiring GND connection for thermal and electrical stability. Pin 1 is I/O VL1; Pin 20 is I/O VCC1; Pin 10 is EN; Pin 11 is GND; Pin 19 is VCC; Pin 2 is VL; Pin 11 is GND; EP must be soldered to PCB ground plane.

The following parts are listed as comparable options for similar level translation applications.

Compared with MAX3002EUP+, MAX3006EUP+ trades bidirectionality for granular EN-controlled channel partitioning - essential for partial-bus isolation in multi-peripheral embedded systems. Versus TXB0108PWR, it offers guaranteed ±15kV ESD immunity and deterministic 20Mbps timing, at the cost of lower maximum speed.

FAQ

What is the exact function of the EN pin on the MAX3006EUP+?

The EN pin on the MAX3006EUP+ provides segmented channel control: when pulled low, it places IVCC1 and IVCC2 into three-state while activating OVL1 and OVL2; simultaneously, OVCC3–OVCC8 go high-impedance and IVL3–IVL8 engage internal 6kΩ pulldown resistors. This behavior is unique to MAX3006EUP+ within the family and enables selective bus isolation without full device shutdown.

Does the MAX3006EUP+ support bidirectional data flow like the MAX3002EUP+?

No, the MAX3006EUP+ is strictly unidirectional per channel pair and does not support automatic bidirectional translation. Unlike the MAX3002EUP+, it lacks the directionless architecture and relies on fixed VL→VCC or VCC→VL signal paths. Its EN pin controls channel groups rather than enabling bidirectional mode - confirming its role as a segmented unidirectional translator.

What is the maximum data rate achievable with the MAX3006EUP+ under real-world conditions?

The MAX3006EUP+ guarantees 20Mbps operation across its full voltage range (+1.2V ≤ VL ≤ VCC ≤ +5.5V). At optimized conditions (+2.5V ≤ VL ≤ VCC ≤ +3.3V, 15pF load), it achieves up to 35Mbps. Performance depends on driver strength, trace capacitance, and supply voltage - per the formula i > 10⁸ × V × (C + 10pF) for full-speed operation.

Is the ±15kV ESD protection on the MAX3006EUP+ applicable to all I/O pins?

No - the ±15kV Human Body Model (HBM) ESD rating applies exclusively to the I/O VCC pins (I/O VCC1–I/O VCC8), as confirmed in the Absolute Maximum Ratings and Detailed Description sections. The I/O VL pins are protected to standard industry levels (not specified as ±15kV), making MAX3006EUP+ especially suited for externally routed high-side signal paths subject to handling discharge.

Can the MAX3006EUP+ operate with VL greater than VCC?

While VL > VCC during power-up will not damage the MAX3006EUP+, normal operation requires VL ≤ VCC per the datasheet's Level Translation section. Operation outside this condition may cause undefined logic thresholds, increased leakage, or timing violations - so system design must ensure VL ≤ VCC during active data transfer, even if transient exceedance is tolerated at startup.
