Texas Instruments SN74LVC07ADGVR

Overview

SN74LVC07ADGVR from Texas Instruments is a hex buffer/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 consumer audio and SSD power control circuits.

For engineers reviewing the SN74LVC07ADGVR datasheet, SN74LVC07ADGVR pinout, SN74LVC07ADGVR application, or SN74LVC07ADGVR equivalent, key selection criteria include open-drain drive capability, 5.5 V input tolerance across VCC range, Ioff-enabled live insertion support, and TVSOP-14 package compatibility with high-density PCB layouts.

Technical Context

The SN74LVC07ADGVR 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 all outputs when VCC = 0 V, preventing back-drive current during hot-swap or partial-power-down sequences.

Propagation delay is specified down to 2.6 ns at 5 V (–40°C to +85°C), with consistent timing performance maintained across –40°C to +125°C operating range. The device supports mixed-voltage system interfacing - e.g., translating 1.8-V logic to 5-V bus lines - without external level-shifting components.

Key Specifications

FAQ

What is the maximum sink current per output of the SN74LVC07ADGVR?

The SN74LVC07ADGVR supports up to 24 mA sink current per output at VCC = 3 V and ambient temperature, as specified in the Recommended Operating Conditions table. At VCC = 1.65 V, minimum guaranteed sink current is 4 mA. Total device output current must not exceed ±50 mA to maintain reliability.

Does the SN74LVC07ADGVR support hot-swap or partial-power-down operation?

Yes, the SN74LVC07ADGVR includes Ioff circuitry that disables all outputs when VCC = 0 V, limiting input/output leakage to ±10 µA. This feature enables safe live insertion and prevents back-drive current into powered subsystems - a key requirement for hot-swap applications documented in Section 8.3 of the datasheet.

Can the SN74LVC07ADGVR interface 1.8-V logic to a 5-V bus?

Yes, the SN74LVC07ADGVR accepts input voltages up to 5.5 V regardless of VCC setting, and its open-drain outputs can be pulled up to 5 V. When VCC = 1.8 V, inputs driven by 5-V sources remain valid, and outputs sink current into the 5-V rail - enabling robust level translation without external components.

What is the package type and thermal performance of the SN74LVC07ADGVR?

The SN74LVC07ADGVR uses a 14-pin TVSOP (DGV) package measuring 3.60 mm × 4.40 mm with 0.5 mm pitch. Its junction-to-ambient thermal resistance (RθJA) is 157.7°C/W, and junction-to-board (RθJB) is 90.8°C/W, as measured per JEDEC JESD51 standards - suitable for moderate-power density PCB layouts with standard copper pour.

Are unused inputs on the SN74LVC07ADGVR required to be terminated?

Yes, all unused inputs on the SN74LVC07ADGVR must be externally biased to either VCC or GND. Floating CMOS inputs cause increased ICC, noise susceptibility, and potential oscillation. TI's application note SCBA004 explicitly mandates termination - typically via 10-kΩ resistors - to ensure stable operation and prevent undefined logic states.
