Product details
Overview
SN74LVC07ADBR from Texas Instruments is a hex non-inverting buffer/driver with open-drain outputs, designed for 1.65 V to 5.5 V operation. It delivers 24 mA sink current per output at 3.3 V, supports 5.5-V-tolerant inputs/outputs, achieves 2.6 ns max propagation delay at 5 V, and features Ioff for live insertion and partial-power-down protection. It is used in level translation and wired-OR bus interfaces in consumer audio and embedded control systems.
For engineers reviewing the SN74LVC07ADBR datasheet, SN74LVC07ADBR pinout, SN74LVC07ADBR application, or SN74LVC07ADBR equivalent, key selection criteria include open-drain drive strength (24 mA), wide VCC range (1.65–5.5 V), 5.5-V input/output tolerance, Ioff-enabled power sequencing, and SSOP-14 package compatibility with space-constrained PCB layouts.
Technical Context
The SN74LVC07ADBR implements six independent non-inverting open-drain buffers, each capable of sinking up to 24 mA at 3.3 V while maintaining logic-level compatibility across 1.65–5.5 V supply rails. Its Ioff circuitry actively disables outputs when VCC = 0 V, preventing back-drive current and enabling hot-plug capability in mixed-voltage systems.
Input thresholds are voltage-ratio-based (e.g., VIH = 0.7 × VCC at 4.5–5.5 V), and output behavior is defined solely by external pull-up configuration - no internal pull-ups exist. Propagation delay varies with VCC and temperature: 2.6 ns (min) at 5 V/25°C, rising to 3.1 ns at 5 V/125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables direct interface between 1.8-V, 2.5-V, 3.3-V, and 5-V logic domains without level shifters. |
| Output Sink Current | 24 mA per channel at VCC = 3 V - sufficient to drive multiple CMOS inputs or small LEDs directly. |
| Propagation Delay | 2.6 ns max at VCC = 5 V, TA = –40°C to +85°C - supports signal integrity in high-speed digital control paths up to ~100 MHz. |
| Ioff Current | ±10 µA at VCC = 0 V - ensures safe isolation during power sequencing and prevents back-current flow in partial-power-down systems. |
| Input/Output Voltage Tolerance | Up to 5.5 V regardless of VCC - allows inputs driven by higher-voltage sources and outputs pulled up to voltages exceeding VCC. |
| ESD Rating | ±4000 V HBM - meets industrial-grade robustness requirements for handling and board assembly. |
| Operating Temperature | –40°C to +125°C - qualified for automotive under-hood and industrial control environments. |
Pinout & Package
SN74LVC07ADBR is housed in a 14-pin SSOP (Shrink Small Outline Package) with body dimensions 6.20 mm × 5.30 mm and standard 0.65 mm lead pitch. The package is RoHS-compliant, lead-finish NIPDAU, and rated MSL Level-1 (unlimited reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A, 4A, 5A, 6A | Input | CMOS-compatible logic inputs accepting 0–5.5 V; no internal pull-up/down; must be terminated to avoid floating. |
| 1Y, 2Y, 3Y, 4Y, 5Y, 6Y | Open-Drain Output | Active-low outputs requiring external pull-up; sink-only operation; no high-side drive capability. |
| GND (Pin 7) | Ground Reference | Primary return path for all output sink current and internal logic; must be low-impedance and decoupled. |
| VCC (Pin 14) | Power Supply | Single supply rail for internal logic; powers input buffers and output drivers; bypass capacitor required. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.65–5.5 V) | Enables single device deployment across 1.8-V microcontrollers, 3.3-V FPGAs, and 5-V legacy peripherals without discrete translators. |
| 5.5-V tolerant I/O | Permits interfacing with 5-V systems while operating at lower VCC, eliminating need for external clamping diodes or resistors. |

|---|---|
|
Use Scenario: Driving multiple indicator LEDs on a portable audio dock with shared 5-V rail and 3.3-V MCU control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G07DBVR | Single-channel version in SOT-23-5; identical VCC range and Ioff, but only one buffer; 16 mA sink at 3.3 V. | Suitable for point-to-point level translation where space or channel count is constrained; not a drop-in replacement for hex function. | Select SN74LVC1G07DBVR only when single-channel buffering suffices and PCB area is critical; verify layout accommodates SOT-23 footprint. |
| 74AUP1G07GW,125 | NXP part in SC-70-5; lower ICC (0.9 µA typical), 1.8–3.6 V VCC range only; 20 mA sink at 3.3 V; no 5.5-V I/O tolerance. | Better for ultra-low-power battery-operated devices; incompatible with 5-V systems or mixed-voltage translation. | Choose 74AUP1G07GW,125 for energy-sensitive designs within 1.8–3.6 V domain; avoid if 5-V tolerance or >3.6 V operation is required. |
Compared with SN74LVC1G07DBVR and 74AUP1G07GW,125, the SN74LVC07ADBR uniquely combines hex-channel density, 5.5-V I/O tolerance, and 24-mA drive in a space-efficient SSOP-14 package - making it optimal for multi-signal translation and bus arbitration in consumer and industrial control boards.

FAQ
What is the maximum sink current per output of the SN74LVC07ADBR?
The SN74LVC07ADBR supports up to 24 mA sink current per output when VCC = 3 V and ambient temperature is 25°C. This rating decreases slightly at higher temperatures or lower VCC values - for example, it drops to 12 mA at VCC = 2.3 V. The absolute maximum continuous output current remains ±50 mA total across all six channels, so design must ensure no single output exceeds its rated sink capability under worst-case thermal conditions. The SN74LVC07ADBR datasheet specifies these limits in Section 6.3 (Recommended Operating Conditions) and Table 6.5 (Electrical Characteristics).
Does the SN74LVC07ADBR have internal pull-up resistors on its outputs?
No, the SN74LVC07ADBR does not include internal pull-up resistors. Its outputs are strictly open-drain and require external pull-up resistors to define the high logic state. The value of the pull-up resistor depends on the target voltage (e.g., 3.3 V or 5 V), desired rise time, and capacitive load - typically 1 kΩ to 10 kΩ for general-purpose use. This architecture enables flexible voltage translation and wired-OR functionality, which is explicitly documented in Section 8.1 (Overview) and Figure 7 (Typical Application Diagram) of the SN74LVC07ADBR datasheet.
Can the SN74LVC07ADBR operate with a 1.8-V supply and interface to 5-V logic?
Yes, the SN74LVC07ADBR can operate with a 1.8-V VCC supply while safely accepting 5-V input signals and driving outputs pulled up to 5 V. Its inputs and outputs are rated for voltages up to 5.5 V regardless of VCC, enabling bidirectional voltage translation without external components. This capability is confirmed in Section 8.3 (Feature Description) and Table 6.3 (Recommended Operating Conditions), where VI and VO ranges are specified as 0–5.5 V. The SN74LVC07ADBR thus functions reliably in mixed-voltage systems such as FPGA-to-peripheral bridges.
What is the purpose of the Ioff feature in the SN74LVC07ADBR?
The Ioff feature in the SN74LVC07ADBR disables all outputs when VCC = 0 V, limiting input/output leakage current to ±10 µA. This prevents damaging back-current flow during power sequencing, live insertion, or partial-power-down modes - critical in modular systems like docking stations or hot-swappable modules. The Ioff specification is verified per JESD78 and appears in Table 6.5 (Electrical Characteristics) of the SN74LVC07ADBR datasheet, ensuring safe operation even when upstream logic remains powered while the SN74LVC07ADBR is unpowered.
What package type is used for the SN74LVC07ADBR?
The SN74LVC07ADBR uses a 14-pin SSOP (Shrink Small Outline Package) with dimensions 6.20 mm × 5.30 mm and 0.65 mm lead pitch. It is RoHS-compliant, has NIPDAU lead finish, and carries an MSL Level-1 rating (unlimited floor life). This package is distinct from other variants like SN74LVC07AD (SOIC-14) or SN74LVC07ARGY (VQFN-14), and its mechanical data is fully detailed in TI's Packaging Information addendum and Section 13 of the SN74LVC07ADBR datasheet.
