Texas Instruments SN74LVC07ADRG3

Overview

SN74LVC07ADRG3 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, 2.6 ns max propagation delay at 5 V, and 5.5 V-tolerant inputs/outputs - used in level translation, wired-OR logic, and LED driving in consumer audio and SSD power control.

For engineers reviewing the SN74LVC07ADRG3 datasheet, SN74LVC07ADRG3 pinout, SN74LVC07ADRG3 application, or SN74LVC07ADRG3 equivalent, key selection criteria include open-drain drive strength, Ioff-enabled partial-power-down capability, voltage translation across 1.65–5.5 V rails, and SOIC-14 package compatibility with legacy board layouts.

Technical Context

The SN74LVC07ADRG3 implements six identical CMOS buffer stages, each with an open-drain output stage capable of sinking up to 24 mA at VCC = 3 V and 5.5 V-tolerant inputs that operate independently of supply voltage. Its Ioff circuitry actively disables outputs when VCC = 0 V, preventing back-drive current during hot insertion or partial power-down.

This device functions as a unidirectional level translator: inputs accept logic-high signals up to 5.5 V regardless of VCC (1.65–5.5 V), while outputs interface with external pull-up networks to generate active-low wired-OR or active-high wired-AND logic - enabling interoperability between 1.8-V, 2.5-V, 3.3-V, and 5-V subsystems without direction control pins.

FAQ

What is the maximum sink current per output of the SN74LVC07ADRG3?

The SN74LVC07ADRG3 supports up to 24 mA sink current per output at VCC = 3 V and ambient temperature of 25°C. At VCC = 5 V, the rated sink current is 24 mA with VOL ≤ 0.55 V. This value decreases slightly at higher temperatures or lower VCC, as specified in the Electrical Characteristics table of the official datasheet. The total device output current must not exceed ±50 mA.

Does the SN74LVC07ADRG3 support level translation between different voltage domains?

Yes, the SN74LVC07ADRG3 supports bidirectional level translation: its inputs accept voltages up to 5.5 V regardless of VCC (1.65–5.5 V), and its open-drain outputs interface with external pull-ups tied to any higher voltage rail (e.g., 5 V), enabling translation from 1.8-V or 2.5-V logic to 5-V signaling. No direction control is required.

Can unused inputs on the SN74LVC07ADRG3 be left floating?

No, unused inputs on the SN74LVC07ADRG3 must be tied to either VCC or GND to prevent undefined logic states and excessive power consumption. Floating CMOS inputs can cause oscillation or increased ICC due to intermediate voltage levels triggering both NMOS and PMOS transistors simultaneously - TI explicitly recommends biasing all unused inputs to a valid logic level.

What is the purpose of the Ioff feature in the SN74LVC07ADRG3?

The Ioff feature in the SN74LVC07ADRG3 disables output buffers when VCC = 0 V, limiting input/output leakage current to ±10 µA. This prevents back-current flow from live system buses into a powered-down device - essential for hot-swap capability, partial-power-down modes, and safe insertion into live backplanes or modular systems.

Is the SN74LVC07ADRG3 RoHS compliant and what is its MSL rating?

Yes, the SN74LVC07ADRG3 is RoHS compliant (lead-free, Sn finish) and has a Moisture Sensitivity Level (MSL) rating of Level-1 at 260°C peak reflow - meaning it is not moisture-sensitive and does not require dry-packaging or baking prior to assembly, simplifying manufacturing logistics and reducing handling overhead.
