Nexperia USA Inc. 74LVC3G07GS,115

Overview

74LVC3G07GS,115 from Nexperia is a triple non-inverting buffer IC with open-drain outputs, designed for level translation and wired-logic interfacing in mixed-voltage systems. It operates from 1.65 V to 5.5 V, accepts 5 V-tolerant inputs, features Schmitt-trigger inputs for noise immunity, and supports IOFF partial power-down protection. It is used in I²C bus buffering, LED sink drivers, and voltage-level shifting between 3.3 V and 5 V domains.

For engineers reviewing the 74LVC3G07GS,115 datasheet, 74LVC3G07GS,115 pinout, 74LVC3G07GS,115 application, or 74LVC3G07GS,115 equivalent, key selection criteria include open-drain drive capability (–24 mA at VCC = 3.0 V), wide supply range (1.65–5.5 V), –40 °C to +125 °C operation, IOFF-enabled power-down isolation, and XSON8 package compatibility with high-density PCB layouts.

Technical Context

This device implements three independent non-inverting buffers, each with an open-drain output enabling wired-OR/AND logic functions. All inputs incorporate Schmitt-trigger action, ensuring robust operation with slow-rising or noisy signals across its full temperature and voltage range.

The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during partial power-down-critical for hot-swap and multi-rail system integrity. Input tolerance up to 5.5 V allows direct interfacing with legacy 5 V TTL or CMOS logic without external level shifters.

FAQ

Can 74LVC3G07GS,115 be used with a 1.8 V supply and 5 V inputs?

Yes. The device supports VCC as low as 1.65 V and tolerates input voltages up to 5.5 V regardless of supply level. This allows direct connection of 5 V sensors or switches to a 1.8 V microcontroller's GPIO via the buffer's 5 V-tolerant inputs, with outputs referenced to the 1.8 V domain when pulled up accordingly.

What is the purpose of the IOFF feature, and how does it behave during power sequencing?

IOFF disables all outputs when VCC drops to 0 V, forcing them into high-impedance state. This prevents backflow current from live downstream circuits (e.g., 5 V pull-ups) into the unpowered IC, protecting both the buffer and connected devices during hot-plug or staggered power-up sequences in multi-rail systems.

How do the Schmitt-trigger inputs improve system reliability?

Schmitt-trigger inputs provide hysteresis (typically ~0.3–0.5 V), meaning the threshold for detecting a HIGH differs from that for detecting a LOW. This eliminates false triggering caused by slow-rising signals, contact bounce, or EMI-induced noise-making the device ideal for push-button interfaces, mechanical switch conditioning, and noisy industrial environments.

Is an external pull-up resistor required on each open-drain output?

Yes. Open-drain outputs can only sink current; they cannot source it. Each 1Y, 2Y, or 3Y output must be connected to a pull-up resistor (value selected based on speed, current, and voltage requirements) to establish a valid HIGH logic level. Typical values range from 1 kΩ (fast, high-current) to 10 kΩ (low-power, slower edges).
