Product details
Overview
MAX3002EUP+T from Maxim Integrated is an 8-channel bidirectional logic-level translator IC enabling voltage translation between +1.2V to +5.5V (VL) and +1.65V to +5.5V (VCC) domains without direction control pins. It supports guaranteed 20Mbps data rate, features ±15kV HBM ESD protection on I/O VCC lines, consumes only 0.1µA supply current in shutdown, and operates across –40°C to +85°C. It is used in SPI/MICROWIRE interfaces between low-voltage ASICs and 3.3V/5V systems.
For engineers reviewing the MAX3002EUP+T datasheet, MAX3002EUP+T pinout, MAX3002EUP+T application, or MAX3002EUP+T equivalent, key selection criteria include bidirectional operation without direction pin, 20Mbps timing performance at 1.8V–3.3V rails, EN-controlled three-state output mode, ultra-low shutdown current (<2µA), and compatibility with TSSOP-20 PCB footprints.
Technical Context
The MAX3002EUP+T implements a passive-bidirectional architecture that enables automatic signal flow in either direction (VL ↔ VCC) per channel using internal pass-gate logic-no external direction control required. Its input thresholds are dynamically referenced to VL (VIHL = 2/3×VL, VILL = 1/3×VL) and VCC (VIHC = 2/3×VCC, VILC = 1/3×VCC), ensuring robust noise margin across voltage combinations.
It integrates an active-enable input (EN) that places all eight I/O VCC terminals into high-impedance three-state while applying 6kΩ pulldowns to I/O VL lines. Propagation delay is specified as ≤20ns (I/O VL → I/O VCC) and ≤20ns (I/O VCC → I/O VL) under 50pF load at 20Mbps, with channel-to-channel skew ≤5ns at 1.2V–3.3V operation.
Key Specifications

Pinout & Package
MAX3002EUP+T is packaged in a 20-pin TSSOP (5.0mm × 6.5mm, 0.65mm pitch) with exposed pad. Pin 1 is I/O VL1; pin 10 is EN; pin 11 is GND; pin 19 is VCC; pin 20 is I/O VCC1. All I/O VL pins (1,3–9) reference VL; all I/O VCC pins (12–18,20) reference VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| I/O VL1–I/O VL8 (pins 1,3–9) | Bidirectional data terminal (VL side) | Accepts or drives signals at VL voltage; auto-senses direction; no external pull-ups required. |
| I/O VCC1–I/O VCC8 (pins 12–18,20) | Bidirectional data terminal (VCC side) | Translates VL-side logic to VCC levels and vice versa; rail-to-rail swing compatible with CMOS inputs. |
| VL (pin 2) | Low-voltage supply reference | Sets input/output thresholds for VL-side I/O; must be bypassed with 0.1µF capacitor to GND. |
| VCC (pin 19) | High-voltage supply reference | Sets thresholds for VCC-side I/O; requires local 0.1µF decoupling; supports up to 5.5V. |
| EN (pin 10) | Enable control input | Pull low to disable all VCC-side outputs (three-state) and activate 6kΩ pulldowns on VL-side I/O. |
| GND (pin 11) | Ground reference | Common return path for both supply domains; connects to exposed pad for thermal and EMI performance. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0108E | 8-channel, 3.6V max VCC, no ±15kV ESD, 60Mbps rated but not guaranteed at low voltage | Lacks integrated ESD protection; requires external diodes for handheld use; higher quiescent current (5µA) | Select when highest speed (>20Mbps) is required at 3.3V and ESD is managed externally. |
| SN74AVC8T245 | Unidirectional, direction pin required, 3.6V max VCC, no ESD rating, 24mA drive strength | Requires GPIO for DIR control; unsuitable for hot-swap or dynamic bus arbitration scenarios | Select when driving heavy capacitive loads (>30pF) or when strict unidirectional control is preferred. |
Compared with TXS0108E and SN74AVC8T245, the MAX3002EUP+T uniquely delivers guaranteed 20Mbps bidirectional operation with integrated ±15kV ESD and sub-2µA shutdown-making it optimal for space-constrained, battery-powered, and connector-facing applications where reliability and simplicity are prioritized over raw speed or high drive strength.

FAQ
What is the maximum guaranteed data rate for MAX3002EUP+T?
The MAX3002EUP+T is guaranteed to operate at 20Mbps across its full specified operating voltage range (+1.2V ≤ VL ≤ VCC ≤ +5.5V). At optimized conditions (e.g., +1.8V ≤ VL ≤ VCC ≤ +2.5V), it supports up to 30Mbps, and at +2.5V ≤ VL ≤ VCC ≤ +3.3V, up to 35Mbps-though only the 20Mbps rating is production-tested and guaranteed over temperature.
Does MAX3002EUP+T require a direction control signal?
No, the MAX3002EUP+T uses a passive-bidirectional architecture that automatically detects signal direction on each channel without any direction (DIR) pin or configuration register. This eliminates firmware dependencies and PCB routing for control lines-unlike unidirectional translators such as SN74AVC8T245.
What is the purpose of the EN pin on MAX3002EUP+T?
The EN pin on MAX3002EUP+T controls output enable state: when pulled low, all eight I/O VCC pins enter high-impedance three-state mode, while all eight I/O VL pins are actively pulled down via internal 6kΩ resistors. This allows safe bus sharing and low-power sleep modes without external pull-down networks.
Can MAX3002EUP+T translate between 1.2V and 5V logic domains?
Yes-MAX3002EUP+T accepts VL from +1.2V to +5.5V and VCC from +1.65V to +5.5V, with the constraint that VL ≤ VCC. Therefore, it supports 1.2V ↔ 3.3V, 1.8V ↔ 5V, and 2.5V ↔ 5V translation, but not 1.2V ↔ 5V directly (since 1.2V < 5V satisfies VL ≤ VCC, this *is* supported). Power-up sequencing tolerance allows VL ≥ VCC temporarily without damage.
Is MAX3002EUP+T pin-compatible with other devices in the MAX3000E/MAX3001E/MAX3002–MAX3012 family?
Yes-MAX3002EUP+T shares identical 20-pin TSSOP pinout, supply connections, and I/O mapping with MAX3000E, MAX3001E, and MAX3003 through MAX3012 in the same package variant. However, data rate, ESD rating, and EN functionality differ across variants; electrical substitution requires validation of timing, protection, and enable behavior for the target application.
