Texas Instruments SN74LVC3G07YEAR

Overview

SN74LVC3G07YEAR from Texas Instruments is a triple non-inverting buffer/driver with open-drain outputs, designed for 1.65-V to 5.5-V VCC operation. It delivers 3.7 ns max propagation delay at 3.3 V, ±24-mA output sink drive, and supports Ioff partial-power-down protection. It enables wired-OR logic in level-shifting I²C bus interfaces and voltage translation circuits.

For engineers reviewing the SN74LVC3G07YEAR datasheet, SN74LVC3G07YEAR pinout, SN74LVC3G07YEAR application, or SN74LVC3G07YEAR equivalent, key selection considerations include open-drain output compatibility, Ioff-enabled live insertion, 3.3-V/5-V mixed-voltage interface support, and NanoFree™ DSBGA package suitability for space-constrained PCB layouts.

Technical Context

This device integrates three independent non-inverting buffers, each with an open-drain output stage capable of sinking up to 32 mA. Its Ioff circuitry actively disables outputs during power-down, preventing backflow current when VCC = 0 V - critical for hot-swap and partial-power-down systems.

The input structure accepts voltages up to 5.5 V regardless of VCC level (1.65–5.5 V), enabling robust level translation between 1.8-V, 3.3-V, and 5-V domains. Output VOL remains ≤0.55 V at IOL = 24 mA and VCC = 3 V, ensuring reliable low-state signaling into standard pull-up networks.

FAQ

What is the function of SN74LVC3G07YEAR?

The SN74LVC3G07YEAR is a triple non-inverting buffer with open-drain outputs. Each channel passes its input signal unchanged to the output, but only sinks current - requiring an external pull-up resistor to establish a logic HIGH state. It supports voltage translation across 1.65–5.5 V domains and includes Ioff protection for partial-power-down operation.

Does SN74LVC3G07YEAR support 5-V tolerant inputs?

Yes, SN74LVC3G07YEAR accepts input voltages up to 5.5 V regardless of VCC level - including when VCC is as low as 1.65 V. This allows direct interfacing with 5-V microcontrollers or sensors without external level-shifting components, simplifying design and reducing BOM count.

What package type is used for SN74LVC3G07YEAR?

SN74LVC3G07YEAR uses the YZP package: an 8-ball DSBGA (Die Size Ball Grid Array) measuring 1.5 mm × 1.5 mm × 0.5 mm. It implements TI's NanoFree™ technology, eliminating traditional packaging materials to minimize size, weight, and parasitic inductance.

Can SN74LVC3G07YEAR be used in I²C bus applications?

Yes, SN74LVC3G07YEAR is commonly deployed for I²C level translation. Its open-drain outputs, 5.5-V input tolerance, and low VOL (<0.55 V at 24 mA) meet I²C electrical specifications. Two channels can buffer SDA and SCL independently, supporting bidirectional communication between mismatched voltage domains.

What is the maximum sink current capability of SN74LVC3G07YEAR?

SN74LVC3G07YEAR supports up to 32 mA sink current per output at VCC = 4.5 V, and 24 mA at VCC = 3 V. This enables direct driving of standard 4.7-kΩ pull-up resistors on 5-V I²C buses or high-brightness LEDs without additional transistor stages.
