Texas Instruments SN74LVC2G07YZAR

Overview

SN74LVC2G07YZAR from Texas Instruments is a dual open-drain buffer IC designed for level translation and wired-OR logic implementation in 1.65-V to 5.5-V systems. It features two independent open-drain outputs capable of sinking up to 32 mA at 4.5 V, supports 5.5-V tolerant inputs, and delivers 3.7 ns max propagation delay at 3.3 V - enabling robust I²C bus extension, LED driving, and power sequencing in portable media players and SSD controllers.

For engineers reviewing the SN74LVC2G07YZAR datasheet, SN74LVC2G07YZAR pinout, SN74LVC2G07YZAR application, or SN74LVC2G07YZAR equivalent, key selection criteria include verified open-drain sink capability (32 mA), Ioff-enabled live insertion support, 5.5-V input tolerance across VCC = 1.65–5.5 V, and NanoFree™ DSBGA package compatibility with high-density PCB layouts.

Technical Context

The SN74LVC2G07YZAR implements two non-inverting open-drain buffers with independent inputs (1A, 2A) and outputs (1Y, 2Y), requiring external pull-up resistors to define high-level voltage. Its Ioff circuitry actively disables outputs during partial power-down, blocking back-current flow when VCC = 0 V.

Input voltage tolerance extends to 5.5 V regardless of VCC setting (1.65–5.5 V), enabling bidirectional level translation between disparate supply domains. The device meets JESD 78 Class II latch-up immunity (>100 mA) and exceeds JEDEC ESD ratings: 2000-V HBM, 1000-V CDM, and 200-V MM.

Key Specifications

Pinout & Package

SN74LVC2G07YZAR uses the YZP (DSBGA-6) package: 1.41 mm × 0.91 mm, bottom-terminal, 0.5-mm pitch, ball grid array with solder bumps. This NanoFree™ package eliminates leadframe and mold compound, reducing parasitic inductance and thermal resistance (RθJA = 123°C/W).

FAQ

What is the maximum sink current specification for SN74LVC2G07YZAR?

The SN74LVC2G07YZAR supports a maximum sink current of 32 mA per output at VCC = 4.5 V, with VOL ≤ 0.55 V. This value is validated across –40°C to 125°C and enables direct LED driving or I²C bus termination without external transistors. At lower VCC (e.g., 3.3 V), the rated sink current is 24 mA with VOL ≤ 0.55 V, as specified in the Electrical Characteristics table of the SN74LVC2G07YZAR datasheet.

Does SN74LVC2G07YZAR support partial power-down functionality?

Yes, SN74LVC2G07YZAR includes Ioff circuitry that disables both outputs when VCC = 0 V, limiting Ioff to ±10 μA at VI or VO = 5.5 V. This feature prevents damaging back-current flow during hot-insertion or multi-rail power sequencing - critical in SSD controllers and mobile phone baseband interfaces where subsystems power up/down independently.

Can SN74LVC2G07YZAR be used for level translation between 1.8-V and 5-V logic domains?

Yes, SN74LVC2G07YZAR supports bidirectional level translation: its inputs tolerate 0–5.5 V regardless of VCC (1.65–5.5 V), and outputs sink current referenced to VCC. When VCC = 1.8 V, the device accepts 5-V inputs and pulls the output line low to <0.45 V (IOL = 4 mA), enabling clean high-to-low translation without external components.

What package type does SN74LVC2G07YZAR use, and what are its key mechanical advantages?

SN74LVC2G07YZAR uses the YZP package - a 6-ball DSBGA with 1.41 mm × 0.91 mm body size and 0.5-mm pitch. As a NanoFree™ device, it replaces traditional leadframe/mold compound with silicon die-as-package, achieving 123°C/W junction-to-ambient thermal resistance and reducing parasitic inductance - essential for stable 32-mA sink operation in compact portable designs.

Is SN74LVC2G07YZAR compatible with I²C bus protocols?

Yes, SN74LVC2G07YZAR is widely used as an I²C bus extender due to its open-drain outputs, 5.5-V input tolerance, and 3.7-ns max propagation delay at 3.3 V. It supports standard-mode (100 kHz) and fast-mode (400 kHz) I²C timing when paired with appropriate pull-up resistors; its Ioff feature further protects the bus during controller reset or sleep states.
