Product details
Overview
74V1T07CTR from STMicroelectronics is a single high-speed CMOS buffer with open-drain output, designed for level-shifting and bus-driving applications between 5V and 3V systems. It features 4.3ns typical propagation delay at 5V, 1µA max quiescent current at 25°C, and input tolerance up to 7V independent of VCC. Used in I²C bus pull-up interfaces and mixed-voltage logic translation.
For engineers reviewing the 74V1T07CTR datasheet, 74V1T07CTR pinout, 74V1T07CTR application, or 74V1T07CTR equivalent, key selection criteria include open-drain drive capability, 0–7V input voltage tolerance, sub-5ns timing, latch-up immunity, and SOT323-5L package compatibility with space-constrained PCB layouts.
Technical Context
This device implements a two-stage CMOS buffer architecture with dedicated open-drain output stage, enabling wired-AND functionality and bidirectional bus interfacing. Its input protection circuit accepts 0–7V regardless of VCC (4.5–5.5V), supporting robust level translation without external clamping diodes.
The C2MOS fabrication process delivers high noise immunity and stable output switching, while power-down protection ensures safe operation during supply sequencing or hot-insertion scenarios. Input leakage remains ≤1.0µA across full temperature range (–55°C to +125°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| tPD (Typ) | 4.3ns at VCC = 5V - enables high-speed I²C standard-mode (100kHz) and fast-mode (400kHz) signal buffering |
| ICC (Max) | 1µA at TA = 25°C - supports ultra-low-power standby in battery-backed systems |
| VIN Range | 0 to 7V independent of VCC - allows direct interface to 3.3V, 5V, or analog signals without level shifters |
| VOL @ 8mA | 0.55V max at VCC = 4.5V - ensures reliable low-state recognition by 5V TTL receivers |
| Operating Temp | –55°C to +125°C - qualified for automotive under-hood and industrial control environments |
| Input Leakage | ±1.0µA max - minimizes loading on high-impedance sensor or reference lines |
| ESD HBM | 2000V - meets JEDEC JS-001 Class 2 for board-level handling robustness |
Pinout & Package
SOT323-5L package: 1.80 × 2.40 mm body, 0.65 mm pitch, 5-terminal surface-mount outline with exposed pad not present. Pin 1 marked via chamfered corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - must be left unconnected or grounded per layout best practice |
| 2 | 1A | CMOS-compatible input - accepts 0–7V; internally protected against overvoltage and ESD |
| 3 | GND | Signal and power reference - requires low-inductance connection to system ground plane |
| 4 | 1Y | Open-drain NMOS output - requires external pull-up to desired bus voltage (e.g., 3.3V or 5V) |
| 5 | VCC | Positive supply - only powers internal logic; does not constrain output pull-up voltage |
Key Features
| Feature | Design Value |
|---|---|
| Input voltage tolerance | 0–7V independent of VCC - eliminates need for external voltage translators in mixed-supply systems |
| Open-drain output | Supports wired-AND, I²C, SMBus, and 1-wire bus topologies with flexible pull-up voltage selection |
| Latch-up immunity | Improved vs. standard CMOS - prevents destructive parasitic SCR activation during transient overvoltage events |
| Power-down protection | Safe input operation with VCC = 0V - enables hot-swap and partial-power-down system architectures |
| Sub-micron C2MOS | Enables 4.3ns propagation delay with <1µA quiescent current - balances speed and static power efficiency |
Applications
| I²C Bus Level Translation | Hot-Swappable Module Interface |
|---|---|
Use Scenario: Interfacing a 3.3V microcontroller I²C master to a 5V sensor slave on shared SDA/SCL lines. IC Role / Device Role / Timing Role: Open-drain buffer providing bidirectional voltage translation without timing skew or signal inversion. Use Value: Eliminates discrete MOSFET translators; maintains I²C timing compliance (tBUF, tHD:DAT) across voltage domains. | Use Scenario: Adding/removing peripheral modules while main system remains powered. IC Role / Device Role / Timing Role: Isolates module-side signals during insertion/removal using power-down tolerant inputs. Use Value: Prevents back-driving of powered logic; enables glitch-free enumeration without host reset. |
| Mixed-Voltage Logic Glue | Industrial Sensor Signal Conditioning |
Use Scenario: Driving 5V TTL inputs from a 3.3V FPGA GPIO bank with open-drain configuration. IC Role / Device Role / Timing Role: Single-gate buffer translating logic levels while preserving signal integrity and noise margin. Use Value: Achieves VIH ≥2.0V and VOL ≤0.55V at 8mA sink - meets TTL input thresholds without external resistors. | Use Scenario: Conditioning analog sensor outputs (0–5V) into digital logic domain with overvoltage-safe sampling. IC Role / Device Role / Timing Role: Input clamp and level translator ensuring ADC or comparator inputs stay within safe voltage window. Use Value: Accepts up to 7V transients without damage; leakage <1µA avoids loading high-Z sensor outputs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar single open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G07DBVR | 3.3V-only VCC range (1.65–5.5V); no 0–7V input tolerance | Requires VCC tied to pull-up voltage; unsuitable for 5V-to-3V translation with independent supplies | Prefer when system uses unified 3.3V rail and lower cost is critical |
| NC7WZ07P6X | Higher ICC (10µA typ); 5.5V absolute max input (vs. 7V) | Limited transient robustness; not recommended for industrial environments with >5.5V coupling risk | Acceptable for consumer-grade 3.3V/5V interfaces with controlled EMI |
Compared with SN74LVC1G07DBVR and NC7WZ07P6X, the 74V1T07CTR uniquely supports 0–7V input operation independent of VCC, enabling true mixed-rail translation and superior transient resilience in automotive and industrial designs.

FAQ
Can 74V1T07CTR drive a 5V pull-up while powered from 3.3V?
No - VCC must be 4.5–5.5V per datasheet. The device does not regulate or boost; it only enables input tolerance up to 7V. For 3.3V VCC operation with 5V pull-up, use a true level translator like TXB0104. 74V1T07CTR's VCC powers internal logic only; output voltage swing is defined by external pull-up.
Is Pin 1 (NC) required to be grounded?
No - Pin 1 is internally unconnected and must remain floating or optionally tied to GND for mechanical stability. Connecting it to any active node may cause unpredictable behavior. STMicroelectronics' layout guidelines specify leaving NC pins unconnected unless otherwise noted in errata.
What is the maximum sink current at 125°C ambient?
IO = ±25mA absolute maximum applies across full temperature range, but VOL rises to 0.55V max at 8mA sink and VCC = 4.5V under worst-case –55°C to +125°C conditions. Derating is not specified; design to 8mA continuous load for guaranteed VOL compliance in extended temperature operation.
Does 74V1T07CTR support I²C Fast Mode Plus (1MHz)?
Yes - with CL ≤ 20pF and appropriate pull-up (e.g., 2.2kΩ to 3.3V), tPLZ/tPZL ≤ 9.0ns (max) at 5V ensures setup/hold margins for 1MHz I²C. However, total bus capacitance and pull-up strength must be validated per physical layout; the device itself meets timing requirements per AC specs.
