Analog Devices Inc./Maxim Integrated MAX3001EEWP+

Overview

MAX3001EEWP+ from Maxim Integrated is an 8-channel bidirectional logic-level translator IC enabling voltage translation between +1.2V and +5.5V domains without direction control pins. It supports guaranteed 4Mbps data rate, ±15kV HBM ESD protection on I/O VCC lines, ultra-low 0.1µA shutdown current, and operates across –40°C to +85°C. It is used in portable communication devices requiring robust signal integrity across mixed-voltage interfaces.

For engineers reviewing the MAX3001EEWP+ datasheet, MAX3001EEWP+ pinout, MAX3001EEWP+ application, or MAX3001EEWP+ equivalent, this page delivers verified electrical specs, package mapping, real-world use cases, and validated alternative parts for multivoltage system design - including SPI/MICROWIRE level translation, smart card readers, and low-voltage ASIC interfacing.

Technical Context

The MAX3001EEWP+ implements a passive-bidirectional architecture that automatically detects signal transitions on either VL- or VCC-referenced I/Os, eliminating need for external direction control. Its internal one-shot accelerator output stage activates only during edge transitions to minimize quiescent current while achieving fast propagation (≤50ns typical) and low skew (≤30ns part-to-part).

It accepts VL from +1.2V to +5.5V and VCC from +1.65V to +5.5V with VL ≤ VCC enforced for reliable operation. The EN input enables three-state mode on all eight VCC-side I/Os while applying 6kΩ pulldowns to VL-side I/Os - critical for bus sharing and hot-swap isolation in portable POS and cellphone cradle designs.

Key Specifications

Pinout & Package

MAX3001EEWP+ is packaged in a 20-pin TSSOP (5.0mm × 6.5mm, 0.65mm pitch) with exposed thermal pad (EP). Pin numbering follows standard TSSOP convention; EP must be soldered to GND for thermal and EMI performance.

FAQ

What is the guaranteed maximum data rate for MAX3001EEWP+?

The MAX3001EEWP+ is guaranteed to operate at 4Mbps across its full specified voltage and temperature range (–40°C to +85°C). This is confirmed in the Electrical Characteristics table under "Maximum Data Rate" with test conditions RS = 50Ω, CVCC = CVL = 50pF. Performance may improve to 10–15Mbps under optimized conditions (e.g., lower load capacitance, 2.5V–3.3V supplies), but 4Mbps is the production-tested minimum guarantee.

Does MAX3001EEWP+ require a direction control signal?

No, MAX3001EEWP+ does not require a direction control signal. It uses a proprietary bidirectional architecture that automatically senses signal transitions on either the VL- or VCC-referenced I/Os and enables translation in both directions simultaneously. This eliminates external direction logic and simplifies PCB layout - a key differentiator versus unidirectional translators like SN74AVC8T245RHLR.

What is the purpose of the EN pin on MAX3001EEWP+?

The EN pin on MAX3001EEWP+ controls output enable functionality: when driven low, it places all eight I/O VCC lines in high-impedance (three-state) mode while activating 6kΩ pulldown resistors on all eight I/O VL lines. This isolates the VCC-side bus during power-down or hot-swap events - essential for preventing contention in shared-bus applications such as portable POS systems and cellphone cradles.

Can MAX3001EEWP+ translate between 1.2V and 5.5V logic levels?

Yes, MAX3001EEWP+ supports VL as low as +1.2V and VCC as high as +5.5V, provided VL ≤ VCC. For example, it can translate signals between a 1.2V FPGA I/O bank and a 5.5V industrial controller - maintaining valid logic thresholds (VIHL = 2/3×VL, VIHC = 2/3×VCC) and output drive capability (VOHC = VCC – 0.4V, VOHL = VL – 0.4V) across the full range.

Is the exposed pad (EP) on MAX3001EEWP+ electrically connected?

Yes, the exposed pad (EP) on MAX3001EEWP+ is internally connected to GND and must be soldered to a PCB ground plane. It serves dual purposes: thermal dissipation (reducing θJA by ~25°C/W) and EMI suppression. Leaving EP floating or unconnected violates the Absolute Maximum Ratings and risks thermal runaway or increased noise coupling in high-speed translation paths.
