Texas Instruments SN74LVC07ADBRG4

Overview

SN74LVC07ADBRG4 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 5.5-V-tolerant inputs/outputs, delivering up to 24 mA sink current per output, and achieving 2.6 ns max propagation delay at 5 V - used in level translation, wired-OR logic, and LED driving in consumer audio and display systems.

For engineers reviewing the SN74LVC07ADBRG4 datasheet, SN74LVC07ADBRG4 pinout, SN74LVC07ADBRG4 application, or SN74LVC07ADBRG4 equivalent, key selection considerations include open-drain drive capability, Ioff partial-power-down support, 5.5-V input tolerance, and SSOP-14 package compatibility with mixed-voltage interface design.

Technical Context

The SN74LVC07ADBRG4 implements six identical CMOS buffer stages, each with an open-drain output stage capable of sinking up to 24 mA at 3 V and 12 mA at 2.3 V. Its Ioff circuitry actively disables outputs when VCC = 0 V, preventing back-drive current during hot insertion or partial power-down.

All inputs accept voltages up to 5.5 V regardless of VCC level, enabling bidirectional voltage translation between 1.8-V, 2.5-V, 3.3-V, and 5-V logic domains. Propagation delay is specified from 3.1 ns (5 V, –40°C to 125°C) to 6.1 ns (1.8 V, –40°C to 125°C), with guaranteed operation across –40°C to +125°C.

FAQ

What is the maximum sink current per output of the SN74LVC07ADBRG4?

The SN74LVC07ADBRG4 delivers up to 24 mA sink current per output at VCC = 3 V and 12 mA at VCC = 2.3 V, as specified in the Electrical Characteristics table. This rating applies under recommended operating conditions and ensures reliable drive capability for LEDs, MOSFET gates, and TTL-compatible loads without external amplification. Exceeding 25 mA per output risks exceeding absolute maximum ratings.

Does the SN74LVC07ADBRG4 support level translation between different voltage domains?

Yes, the SN74LVC07ADBRG4 supports bidirectional level translation: its inputs accept voltages up to 5.5 V independent of VCC, and its open-drain outputs can be pulled up to any voltage ≤5.5 V. For example, a 1.8-V microcontroller can safely control a 5-V bus by connecting SN74LVC07ADBRG4 outputs to a 5-V pull-up - verified in TI's Application Report SCAS595W Section 9.1.

Is the SN74LVC07ADBRG4 compatible with hot-swap or partial-power-down systems?

Yes, the SN74LVC07ADBRG4 incorporates Ioff circuitry that disables outputs when VCC = 0 V, preventing back-drive current from live signal lines into unpowered sections. This feature is explicitly validated per JESD78 and supports safe insertion into powered backplanes - confirmed in Section 8.1 and Feature Description of the SN74LVC07ADBRG4 datasheet.

What package type and footprint does the SN74LVC07ADBRG4 use?

The SN74LVC07ADBRG4 uses a 14-pin SSOP (Shrink Small Outline Package) with 6.20 mm × 5.30 mm body size and 0.65-mm lead pitch. It shares pinout and mechanical compatibility with other SSOP-14 logic devices, and its RoHS-compliant NiPdAu finish meets IPC/JEDEC J-STD-020 reflow standards (MSL Level-1).

Can unused inputs on the SN74LVC07ADBRG4 be left floating?

No, unused inputs on the SN74LVC07ADBRG4 must be tied to either VCC or GND to prevent undefined logic states and increased ICC. TI explicitly warns against floating CMOS inputs in Section 11.1 and Application Note SCBA004 - uncontrolled input voltages may cause shoot-through current, oscillation, or excessive power consumption in the internal circuitry.
