Diodes Incorporated 74LVC3G06V8-7

Overview

74LVC3G06V8-7 from Diodes Incorporated is a triple inverter IC with open-drain outputs, designed for voltage-level shifting and power-down signal isolation in mixed-voltage systems. It operates from 1.65V to 5.5V, tolerates 5.5V inputs, delivers −24mA output drive at 3.3V, and features IOFF circuitry for partial power-down protection. Used in notebook I/O control, peripheral interface logic, and set-top box signal conditioning.

For engineers reviewing the 74LVC3G06V8-7 datasheet, 74LVC3G06V8-7 pinout, 74LVC3G06V8-7 application, or 74LVC3G06V8-7 equivalent, this page provides verified functional specifications, VSSOP-8 package details, open-drain design implications, and direct alternatives for level-shifting and isolation use cases.

Technical Context

This device implements three independent CMOS inverters, each with an open-drain output requiring an external pull-up resistor to establish HIGH logic levels. Its IOFF functionality disables all outputs during power-down, preventing backflow current when VCC = 0V while inputs remain biased up to 5.5V.

The input voltage tolerance (−0.5V to 5.5V) and wide VCC range (1.65V–5.5V) enable interoperability between 1.8V, 2.5V, 3.3V, and 5V domains. Propagation delay is 1.0ns (min) to 4.0ns (max) at 3.3V across −40°C to +125°C, supporting high-speed digital interfacing without rail-to-rail output swing.

FAQ

Is an external pull-up resistor required for 74LVC3G06V8-7 operation?

Yes. All three outputs are open-drain and cannot source current. A pull-up resistor must be connected between each Y pin and its target logic rail (e.g., 3.3V or 5V). Typical values range from 2.2kΩ to 10kΩ depending on speed and load capacitance requirements.

Can 74LVC3G06V8-7 be used with VCC = 0V while inputs are held at 3.3V?

Yes. The IOFF feature actively disables outputs when VCC = 0V, limiting leakage to ±10μA maximum. This prevents current backflow from 3.3V inputs into the unpowered VCC node-enabling safe partial power-down in hot-swap or sleep-mode scenarios.

What is the maximum capacitive load the 74LVC3G06V8-7 can drive reliably?

Based on measured tPD and output drive strength, the device supports ≤50pF total load capacitance while maintaining specified propagation delay (≤4.0ns at 3.3V). Exceeding this may increase delay and reduce noise margin; layout parasitics must be included in the total.

Does 74LVC3G06V8-7 support 1.2V logic inputs?

No. Minimum recommended VCC is 1.65V, and input thresholds scale with VCC. At VCC = 1.65V, VIH(min) = 0.65×VCC ≈ 1.07V, making 1.2V inputs marginal and non-compliant with guaranteed switching behavior per datasheet specifications.
