Product details
Overview
SN74AUC1G07DBVT from Texas Instruments is a single non-inverting buffer/driver with open-drain output, designed for 1.65–1.95 V operation and 3.6-V I/O tolerant signaling. It delivers ±8-mA output drive at 1.8 V, achieves 2.5 ns max propagation delay (tpd), and supports sub-1-V operation down to 0.8 V - enabling use in low-voltage logic level translation and wired-OR bus interfaces in portable audio and embedded PC systems.
For engineers reviewing the SN74AUC1G07DBVT datasheet, SN74AUC1G07DBVT pinout, SN74AUC1G07DBVT application, or SN74AUC1G07DBVT equivalent, key selection criteria include its open-drain topology, Ioff partial-power-down capability, 1.8-V optimized timing, ±8-mA drive strength, and SOT-23 (DBV) 5-pin package compatibility with space-constrained PCB layouts.
Technical Context
The SN74AUC1G07DBVT implements a single CMOS non-inverting buffer with open-drain output stage, requiring an external pull-up resistor to define high-level logic states. Its Ioff circuitry actively disables outputs during power-down, preventing back-drive current flow when VCC = 0 V.
It operates across 0.8 V to 2.7 V supply range but is characterized and optimized specifically for 1.65–1.95 V VCC, with guaranteed performance including 2.5 ns max tpd at 1.8 V (CL = 30 pF), 10 µA max ICC, and 0.45 V max VOL at IOL = 8 mA (VCC = 1.65 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 2.7 V - supports ultra-low-voltage operation and mixed-mode I/O interfacing with 3.6-V tolerant inputs/outputs |
| Max tpd | 2.5 ns at 1.8 V, CL = 30 pF - enables high-speed signal buffering in sub-2-V domains without timing bottlenecks |
| Output Drive | ±8 mA at 1.8 V - sufficient to drive standard 50-Ω transmission lines or multiple CMOS inputs with controlled rise/fall times |
| Ioff Support | Active at VCC = 0 V - prevents back-current damage during partial power-down, critical for hot-swap and multi-rail systems |
| VOL (IOL = 8 mA) | 0.45 V max at VCC = 1.65 V - ensures robust low-state margin under load, compatible with 1.8-V LVTTL and LVCMOS thresholds |
| ICC | 10 µA max - minimizes quiescent power in always-on logic paths such as system reset or enable control lines |
| ESD Rating | 2000-V HBM - meets industrial-grade ESD robustness requirements without external protection components |
Pinout & Package
SOT-23 (DBV) 5-pin plastic package, 2.90 mm × 1.60 mm body size, 1.45 mm max height, with gull-wing leads and pin 1 index marking. Compatible with standard reflow profiles (MSL Level-1, 260°C peak).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No internal connection | Unused terminal - must be left floating or tied to GND/VCC per layout best practice; no electrical function |
| 2 (A) | Logic input | CMOS-compatible input accepting 0–3.6 V; VIH ≥ 0.65×VCC ensures reliable high detection across full VCC range |
| 3 (GND) | Ground reference | Primary return path for output current and internal bias; requires low-impedance PCB connection to minimize noise coupling |
| 4 (Y) | Open-drain output | Active-low output only - requires external pull-up to define HIGH state; supports wired-AND/OR bus topologies |
| 5 (VCC) | Positive supply | Power rail for internal logic and output stage; supports Ioff shutdown when de-energized |
Key Features
| Feature | Design Value |
|---|---|
| Open-drain output architecture | Enables active-low wired-OR and active-high wired-AND bus configurations without external logic gates |
| Ioff partial-power-down protection | Disables output drivers when VCC = 0 V, eliminating back-current risk in multi-supply systems during sequencing or fault conditions |
| NanoFree™ packaging | Uses die-as-package construction in SOT-23, reducing footprint by ~30% vs. conventional SOIC while maintaining thermal and mechanical reliability |
| 3.6-V I/O tolerance | Allows direct interface with higher-voltage logic families (e.g., 3.3-V or 5-V peripherals) without level-shifting components |
| Sub-1-V operability | Functional down to 0.8 V VCC - supports emerging ultra-low-power microcontroller I/O domains and battery-backed subsystems |
Applications
| USB OTG Host Detection | Low-Voltage Reset Signal Conditioning |
|---|---|
Use Scenario: Detecting USB device attachment via ID pin voltage level in portable OTG hosts. IC Role / Device Role / Timing Role: SN74AUC1G07DBVT acts as open-drain level translator between 1.8-V USB PHY ID sense and 3.3-V system controller GPIO.

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer/driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G07DBVT | Wider VCC range (1.65–5.5 V); higher VOL (0.55 V @ 4 mA, 1.8 V); 3.5 ns tpd (1.8 V, CL = 30 pF) | Less suitable for sub-1.65-V operation; higher drive impedance limits high-speed bus loading | Choose when interfacing with 5-V peripherals or where higher noise margin is prioritized over speed |
| 74AUP1G07GW,125 | Lower ICC (0.9 µA typ); slower tpd (6.4 ns @ 1.2 V); same open-drain topology and Ioff support | Better for ultra-low-power always-on monitoring; not recommended for >10-MHz signal paths | Choose when minimizing standby current outweighs propagation delay requirements |
Compared with SN74LVC1G07DBVT and 74AUP1G07GW,125, the SN74AUC1G07DBVT uniquely balances sub-2-V speed (2.5 ns), 3.6-V I/O tolerance, and Ioff - making it optimal for high-density portable designs requiring both performance and power-domain isolation.

FAQ
What is the maximum operating voltage for SN74AUC1G07DBVT?
The SN74AUC1G07DBVT supports up to 3.6 V on I/O pins (VI and VO) and 2.7 V on VCC, enabling safe interfacing with higher-voltage logic families while operating its core logic at 1.65–1.95 V. Absolute maximum VCC is 3.6 V, but functional operation above 2.7 V is not guaranteed per datasheet specifications.
Does SN74AUC1G07DBVT require external pull-up resistors?
Yes - the SN74AUC1G07DBVT features an open-drain output (pin 4, Y), which can only actively pull low. An external pull-up resistor to the desired high-level voltage (e.g., 1.8 V or 3.3 V) is mandatory to establish a valid HIGH logic state and enable wired-OR functionality.
Can SN74AUC1G07DBVT operate below 1.0 V?
Yes - the SN74AUC1G07DBVT is fully specified down to 0.8 V VCC and functions reliably in sub-1-V domains. At 0.8 V, it delivers 0.7 mA output drive and maintains logic integrity, supporting next-generation ultra-low-power microcontroller I/O and sensor interface applications.
What is the purpose of the NC pin (pin 1) on SN74AUC1G07DBVT?
Pin 1 of the SN74AUC1G07DBVT is marked NC (No Connection) - it has no internal bond wire or circuit connection. It may be left unconnected, tied to GND for mechanical stability, or routed as a keep-out zone; it carries no electrical function and must not be used as a signal or power path.
How does Ioff functionality protect the SN74AUC1G07DBVT during power-down?
The Ioff circuitry in SN74AUC1G07DBVT disables all output drivers when VCC = 0 V, blocking current flow from powered I/O lines (e.g., 3.3-V buses) into the unpowered device. This prevents damaging back-drive currents and ensures safe partial-power-down operation in multi-rail systems like SSDs and portable AV receivers.
