Product details
Overview
2N7001TDPWR-S from Texas Instruments is a single-bit dual-supply buffered voltage signal converter designed for unidirectional level translation between 1.65V and 3.6V domains. It features VCCA/VCCB dual-rail operation, 100Mbps data rate support, 14µA max combined supply current at 125°C, VCC isolation (output enters high-Z if either supply <100mV), and Ioff partial-power-down protection. It enables GPIO translation between MCU/FPGA and communications modules.
For engineers reviewing the 2N7001TDPWR-S datasheet, 2N7001TDPWR-S pinout, 2N7001TDPWR-S application, or 2N7001TDPWR-S equivalent, key selection considerations include dual-supply rail flexibility (1.65–3.6V), guaranteed 100Mbps operation across full voltage range, thermal performance in X2SON-5 package (RθJA = 462.7°C/W), and verified Ioff leakage ≤±8µA under partial-power-down conditions.
Technical Context
The 2N7001TDPWR-S implements a CMOS-based buffered translation architecture with independent input (A, referenced to VCCA) and output (B, referenced to VCCB) power domains. Its functional block includes ESD-protected input/output stages, balanced push-pull output drivers, and dedicated VCC isolation logic that forces B-port into high-impedance when either VCCA or VCCB falls below 100mV.
It operates in two defined functional modes: logic-high input (≥VIH) produces logic-high output (≥VOH), and logic-low input (≤VIL) produces logic-low output (≤VOL), per Table 7-1. The device supports over-voltage tolerant inputs (up to 4.2V) and integrates negative clamping diodes on all I/O pins per JESD22-A114.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCCA / VCCB Range | 1.65V to 3.6V - Enables translation among 1.8V/2.5V/3.3V system nodes without external biasing. |
| Max Data Rate | 100Mbps - Guaranteed across full supply range and temperature (–40°C to +125°C). |
| ICCA + ICCB | 14µA max at 125°C - Enables ultra-low-power operation in battery-backed or thermally constrained systems. |
| VCC Isolation Threshold | <100mV - Ensures automatic high-impedance output state during supply brownout or sequencing faults. |
| Ioff Leakage | ±8µA max - Prevents back-driving and current injection during partial-power-down of host systems. |
| ESD Rating | HBM ±2000V, CDM ±1000V - Meets industrial-grade ESD robustness without external protection components. |
| Propagation Delay | 0.5–20ns - Varies with supply combination (e.g., 10ns max at VCCA=VCCB=3.3V); supports timing-critical interfaces. |
Pinout & Package
X2SON-5 (DPW) package: 0.80mm × 0.80mm body, 0.4mm pitch, single-row 5-pin layout with exposed thermal pad (no internal connection). Pin 1 (A) and pin 4 (B) are signal terminals; pin 2 (VCCB), pin 5 (VCCA), and pin 3 (GND) provide dual-rail power and reference.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Data Input | Unidirectional input referenced to VCCA; accepts VIH/VIL thresholds defined by VCCA voltage. |
| B | Data Output | Unidirectional output referenced to VCCB; drives VOH/VOL levels compliant with VCCB supply. |
| VCCA | Input Supply Rail | Sets input threshold voltage; must be stable during signal transitions to avoid metastability. |
| VCCB | Output Supply Rail | Determines output drive strength and logic-high level; decoupling required per layout guidelines. |
| GND | Ground Reference | Common return path for both rails; requires low-inductance connection to minimize noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-rail up/down translation | Supports bidirectional voltage node bridging (e.g., 1.8V→3.3V up-translation or 3.3V→1.8V down-translation) using same device. |
| VCC isolation | Automatically disables output (high-Z) if either VCCA or VCCB drops below 100mV - prevents bus contention during power sequencing. |
| Ioff partial-power-down | Limits leakage to ±8µA when either supply is at 0V - enables safe hot-insertion and subsystem sleep modes. |
| ESD-hardened I/O | Integrated ±2000V HBM / ±1000V CDM protection eliminates need for discrete TVS diodes in most applications. |
| Low dynamic power | CpdB = 12–18pF (B-port) and CpdA = 1–1.8pF (A-port) enable efficient high-speed switching with minimal AC loading. |
Applications
| MCU/FPGA GPIO Translation | Communications Module Interface |
|---|---|
Use Scenario: Interfacing a 1.8V FPGA I/O bank to a 3.3V UART transceiver in an industrial gateway. IC Role / Device Role / Timing Role: Unidirectional level shifter converting FPGA transmit signals (1.8V LVTTL) to 3.3V logic levels for transceiver input.

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0101DPYR | Auto-direction sensing; open-drain outputs; no VCC isolation; 60Mbps max. | Requires external pull-up resistors; unsuitable for systems requiring guaranteed high-Z on supply loss. | Select when bidirectional translation is needed and VCC isolation is not required. |
| SN74AVC1T45DBVR | Direction-controlled (DIR pin); push-pull outputs; 500Mbps max; no VCC isolation. | Needs direction control logic; higher speed but lacks fail-safe high-Z behavior during brownout. | Select for higher-speed bidirectional paths where active direction management is acceptable. |
Compared with TXS0101DPYR and SN74AVC1T45DBVR, the 2N7001TDPWR-S uniquely combines unidirectional simplicity, guaranteed VCC isolation, and 100Mbps operation in a 0.64mm² X2SON package - making it optimal for space-constrained, safety-aware level-shifting where supply fault resilience is critical.

FAQ
What is the maximum operating temperature for the 2N7001TDPWR-S?
The 2N7001TDPWR-S is fully specified from –40°C to +125°C ambient temperature. Its thermal resistance (RθJA = 462.7°C/W in X2SON-5 package) and electrical characteristics-including 14µA max ICCA+ICCB at 125°C-guarantee reliable operation across this full industrial range without derating.
Does the 2N7001TDPWR-S support bidirectional signal translation?
No, the 2N7001TDPWR-S is strictly unidirectional: signal flows only from A (input, referenced to VCCA) to B (output, referenced to VCCB). It does not support reverse translation or auto-direction sensing. For bidirectional use, consider alternatives like SN74AVC1T45DBVR.
Can the 2N7001TDPWR-S operate with VCCA = 1.65V and VCCB = 3.3V simultaneously?
Yes, the 2N7001TDPWR-S is explicitly rated for simultaneous operation across the full 1.65V–3.6V range on each rail. This configuration enables robust 1.65V-to-3.3V up-translation with guaranteed VOH ≥2.3V and VOL ≤0.7V at 12mA load, per Electrical Characteristics table.
What is the purpose of the VCC isolation feature in the 2N7001TDPWR-S?
The VCC isolation feature ensures the B-port output enters a high-impedance state whenever either VCCA or VCCB drops below 100mV. This prevents bus contention, back-driving, or undefined logic states during power sequencing, brownout, or hot-swap events-critical for system-level fault tolerance.
Is a bypass capacitor required for the 2N7001TDPWR-S, and if so, what value?
Yes, a 0.1µF ceramic bypass capacitor is recommended on both VCCA and VCCB pins, placed as close as possible to the respective pins. This stabilizes supply rails during fast switching transitions and suppresses high-frequency noise, ensuring consistent 100Mbps performance and meeting layout guidelines in Section 8.4.
