Product details
Overview
SN74LVC07AD from Texas Instruments is a hex buffer and driver IC with six independent open-drain outputs, designed for 1.65 V to 5.5 V operation, supporting 24 mA sink current per output at 3.3 V, 5.5 V-tolerant inputs/outputs, and Ioff partial-power-down protection - used in level translation, wired-OR logic, and LED driving in mixed-voltage systems.
For engineers reviewing the SN74LVC07AD datasheet, SN74LVC07AD pinout, SN74LVC07AD application, or SN74LVC07AD equivalent, key selection criteria include open-drain drive capability, voltage translation range (1.65–5.5 V), Ioff support for live insertion, thermal performance in SOIC-14, and compatibility with 1.8 V/2.5 V/3.3 V/5 V logic families.
Technical Context
The SN74LVC07AD implements six identical CMOS buffer stages, each with an open-drain output requiring an external pull-up resistor. Its Ioff circuitry actively disables all outputs when VCC = 0 V, preventing back-drive current and enabling safe hot-plug operation in partial-power-down systems.
Each channel operates as a non-inverting buffer: low input drives output to low (sinking up to 24 mA), high input places output in high-impedance state. Propagation delay is 2.6 ns max at 5 V, and input thresholds scale with VCC across 1.65–5.5 V supply range.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LV07A | Lower drive (16 mA max at 3.3 V), 1.65–5.5 V supply, no Ioff support | Not suitable for partial-power-down or hot-swap use cases; limited sink strength for LED or bus loading | Select SN74LV07A only if Ioff and >20 mA drive are unnecessary and cost is primary constraint |
| 74LVC06A | Inverting function (six inverters vs. six buffers), identical electrical specs and packaging | Requires logic inversion in signal path; unsuitable where polarity preservation is required (e.g., direct LED anode control) | Choose 74LVC06A only when inverting behavior aligns with system-level logic architecture |
Compared with SN74LV07A and 74LVC06A, SN74LVC07AD uniquely combines non-inverting open-drain buffering, 24 mA drive, and Ioff - making it the only option among the three for hot-pluggable, polarity-critical, high-current sink applications.

FAQ
What is the maximum sink current per output of the SN74LVC07AD?
The SN74LVC07AD delivers up to 24 mA sink current per output at VCC = 3 V and TA = 25 °C, as specified in the Electrical Characteristics table. At VCC = 1.65 V, minimum guaranteed sink current is 4 mA. This drive strength enables direct interface with multiple TTL loads or discrete LEDs without external amplification - a key design advantage of the SN74LVC07AD in space-constrained applications.
Does the SN74LVC07AD support level translation between different voltage domains?
Yes, the SN74LVC07AD supports both up-translation and down-translation due to its 5.5 V-tolerant inputs and outputs. For example, with VCC = 1.8 V, inputs can accept 3.3 V or 5 V signals, and outputs can be pulled up to 3.3 V or 5 V rails. This capability is intrinsic to the SN74LVC07AD's open-drain architecture and is explicitly validated across the full 1.65–5.5 V supply range in TI's datasheet.
What does Ioff functionality mean for the SN74LVC07AD, and how is it implemented?
Ioff in the SN74LVC07AD refers to automatic output disable when VCC = 0 V, limiting input/output leakage to ±10 µA. This feature prevents damaging back-current during power sequencing or hot-swap events. It is implemented via internal circuitry that isolates all I/O paths from the core logic when supply is absent - a verified behavior confirmed in the SN74LVC07AD's Recommended Operating Conditions and Absolute Maximum Ratings tables.
Can unused inputs on the SN74LVC07AD be left floating?
No, unused inputs on the SN74LVC07AD must be tied to a valid logic level - either VCC or GND - to prevent undefined output states and excessive power consumption. TI's datasheet explicitly states in Section 11.1 that floating CMOS inputs cause unpredictable operation and recommends biasing all unused inputs. This requirement applies uniformly across all six channels of the SN74LVC07AD and is critical for stable system behavior.
What is the thermal performance of the SN74LVC07AD in its SOIC-14 package?
In the SOIC-14 (D) package, the SN74LVC07AD has a junction-to-ambient thermal resistance (RθJA) of 177.4 °C/W and a junction-to-board resistance (RθJB) of 70.6 °C/W, measured at VCC = 3.3 V and TA = 25 °C. These values confirm suitability for moderate-power-density PCB layouts without forced airflow. The SN74LVC07AD's thermal metrics are fully documented in Table 6.4 of its official datasheet and apply specifically to the SN74LVC07AD variant.
