Texas Instruments SN74LVC07ARGYRG4

Overview

SN74LVC07ARGYRG4 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. 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 logic in consumer audio/video systems.

For engineers reviewing the SN74LVC07ARGYRG4 datasheet, SN74LVC07ARGYRG4 pinout, SN74LVC07ARGYRG4 application, or SN74LVC07ARGYRG4 equivalent, key selection criteria include open-drain drive strength, voltage translation capability across 1.65–5.5 V rails, Ioff-enabled power sequencing, thermal performance in VQFN packaging, and compatibility with mixed-voltage digital interfaces.

Technical Context

The SN74LVC07ARGYRG4 implements six identical CMOS buffer stages, each with an open-drain output requiring external pull-up for logic high assertion. Its Ioff circuitry actively disables all outputs when VCC = 0 V, blocking back-drive current and enabling hot-plug operation in multi-rail systems.

Input thresholds are voltage-scalable (e.g., VIH = 0.7 × VCC at 5 V), and output voltage tolerance extends to 5.5 V regardless of VCC - enabling robust interfacing between 1.8-V, 2.5-V, 3.3-V, and 5-V logic domains without level-shifter ICs.

FAQ

What is the maximum sink current per output of the SN74LVC07ARGYRG4?

The SN74LVC07ARGYRG4 supports up to 24 mA sink current per output at VCC = 3 V, as specified in the Electrical Characteristics table under IOL conditions. This rating holds across the full operating temperature range (–40°C to +125°C) and enables direct driving of multiple CMOS inputs or low-power LEDs without external amplification. The SN74LVC07ARGYRG4 maintains this capability while preserving signal integrity and thermal stability in its VQFN package.

Does the SN74LVC07ARGYRG4 support level translation between different voltage domains?

Yes, the SN74LVC07ARGYRG4 supports bidirectional level translation: its inputs and outputs tolerate voltages up to 5.5 V regardless of VCC, allowing it to translate signals from 1.8-V or 2.5-V sources to 3.3-V or 5-V buses using appropriate pull-up resistors. This capability is explicitly confirmed in the Features and Detailed Description sections of the datasheet. The SN74LVC07ARGYRG4 leverages this to simplify mixed-voltage interface design without additional ICs.

What is the purpose of the Ioff feature in the SN74LVC07ARGYRG4?

The Ioff feature in the SN74LVC07ARGYRG4 disables all outputs when VCC = 0 V, limiting input/output leakage to ±10 µA and preventing destructive back-current flow during power sequencing or hot-insertion events. This is critical in modular systems like docking stations or server blades where subsystems power up/down independently. The SN74LVC07ARGYRG4 implements Ioff per JEDEC JESD78 standards, ensuring safe operation in partial-power-down modes.

Can the SN74LVC07ARGYRG4 be used in wired-OR configurations?

Yes, the SN74LVC07ARGYRG4 is specifically designed for wired-OR applications: its six open-drain outputs can be externally tied together with a single pull-up resistor to implement active-low bus arbitration or interrupt aggregation. The datasheet confirms this use case in Section 8.1 Overview and Figure 7 Typical Application Diagram. When used this way, the SN74LVC07ARGYRG4 ensures glitch-free, contention-free logic combining across multiple peripherals.

What is the thermal resistance (RθJA) of the SN74LVC07ARGYRG4 VQFN package?

The SN74LVC07ARGYRG4 in the RGY (VQFN-14) package has a junction-to-ambient thermal resistance (RθJA) of 80.6°C/W, as documented in Section 6.4 Thermal Information. This value is measured under standard JEDEC test conditions (single-layer board, no copper pour) and reflects superior heat dissipation compared to SOIC or TSSOP variants. For thermal design, this means the SN74LVC07ARGYRG4 can sustain higher continuous output loading in compact layouts without exceeding junction temperature limits.
