Texas Instruments SN74LVC07ADRG4

Overview

SN74LVC07ADRG4 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, wired-OR logic, and LED driving in consumer audio/video systems.

For engineers reviewing the SN74LVC07ADRG4 datasheet, SN74LVC07ADRG4 pinout, SN74LVC07ADRG4 application, or SN74LVC07ADRG4 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 SOIC-14 package compatibility with legacy board layouts.

Technical Context

The SN74LVC07ADRG4 implements six identical CMOS buffer stages, each with an open-drain output stage capable of sinking up to 24 mA at 3.3 V while maintaining VOL ≤ 0.4 V. Its Ioff circuitry actively disables all outputs when VCC = 0 V, preventing back-drive current from external signals on inputs or outputs.

All inputs accept voltages up to 5.5 V regardless of VCC setting-enabling reliable level translation between 1.8-V, 2.5-V, 3.3-V, and 5-V logic domains. Propagation delay is specified from 2.6 ns (5 V) to 6.1 ns (–40°C to 125°C, 1.8 V), with consistent timing behavior across the full industrial temperature range (–40°C to +125°C).

FAQ

What is the maximum sink current per output of the SN74LVC07ADRG4?

The SN74LVC07ADRG4 supports up to 24 mA sink current per output at VCC = 3 V, with VOL ≤ 0.55 V. This rating holds across the full operating temperature range (–40°C to +125°C) and is validated per TI's switching characteristics test conditions. Exceeding 24 mA risks violating VOL spec or exceeding absolute max ratings.

Can SN74LVC07ADRG4 interface a 1.8-V microcontroller with a 5-V peripheral?

Yes. SN74LVC07ADRG4 accepts 1.8-V logic inputs and tolerates 5.5-V signals on both inputs and outputs, making it ideal for bidirectional level translation. When used as a buffer from 1.8-V MCU to 5-V peripheral, the open-drain output pulls low while an external 5-V pull-up sets the high state-ensuring clean signal integrity without additional components.

Does SN74LVC07ADRG4 require external pull-up resistors on its outputs?

Yes. Because SN74LVC07ADRG4 has open-drain outputs, each output (pins 2, 4, 6, 8, 10, 12) must be connected to an external pull-up resistor to define the high logic state. Typical values range from 1 kΩ (for fast rise times with heavy loads) to 10 kΩ (for low power with light capacitive loads); value selection depends on bus capacitance and required edge rate.

Is SN74LVC07ADRG4 suitable for hot-swap applications?

Yes. SN74LVC07ADRG4 incorporates Ioff circuitry that disables outputs when VCC = 0 V, limiting input/output leakage to ±10 µA. This prevents back-driving of powered circuitry during live insertion-making it suitable for hot-swap backplanes, modular docking stations, and field-replaceable SSD modules where partial power-down occurs.

What is the thermal resistance (RθJA) of SN74LVC07ADRG4 in its SOIC package?

The SN74LVC07ADRG4 in SOIC-14 (D) package has a junction-to-ambient thermal resistance (RθJA) of 177.4°C/W, measured under standard JEDEC JESD51-2 conditions. This value assumes a two-layer board with 1-in² copper pour; actual thermal performance improves with added copper area, thermal vias, or airflow, and degrades with dense routing or no heatsinking.
