Diodes Incorporated 74LV06AS14-13

Overview

74LV06AS14-13 from Diodes Incorporated is a hex inverter IC with six independent open-drain outputs, designed for voltage translation and signal isolation in mixed-voltage systems. It operates from 2.0V to 5.5V, accepts 5.5V-tolerant inputs, sinks up to 12mA at V_CC = 4.5V, features I_OFF for partial power-down protection, and includes Schmitt-trigger inputs for noise immunity - used in PC peripheral interface logic and notebook power sequencing.

For engineers reviewing the 74LV06AS14-13 datasheet, 74LV06AS14-13 pinout, 74LV06AS14-13 application, or 74LV06AS14-13 equivalent, key selection criteria include open-drain drive capability, 5.5V input tolerance across supply voltages, I_OFF-enabled backflow prevention during power-down, and Schmitt-trigger hysteresis for robust signal conditioning in noisy digital interfaces.

Technical Context

This device implements six identical inverting logic gates, each with an open-drain output requiring external pull-up for high-level assertion. Its I_OFF circuitry actively disables outputs when V_CC = 0V, preventing current backflow into powered-down subsystems - critical for hot-swap and multi-rail isolation.

All inputs incorporate Schmitt-trigger action (typ. 0.6V hysteresis at V_CC = 3V), enabling clean switching on slow or noisy signals. Input voltage range extends to 5.5V regardless of V_CC, supporting level-shifting between 3.3V logic domains and 5V buses without additional translators.

FAQ

Can 74LV06AS14-13 be used with a 1.8V supply?

No. The absolute minimum recommended V_CC is 2.0V per the datasheet's Recommended Operating Conditions. At 1.8V, input thresholds become undefined, propagation delay increases unpredictably, and I_OFF functionality may not activate reliably - risking back-current during power-down. Use 74LVC06A for 1.65V–3.6V operation.

What pull-up resistor value is recommended for the open-drain outputs?

A 1kΩ to 4.7kΩ resistor to the target logic rail (e.g., 3.3V or 5V) is typical. At 12mA sink current and 0.55V max VOL (V_CC = 4.5V), 1kΩ yields ~3.75V high-level output; 4.7kΩ maintains >3.0V while reducing static power. Avoid values >10kΩ if driving capacitive loads >20pF or requiring <10ns rise time.

Does the I_OFF feature require external circuitry to activate?

No. I_OFF activates automatically when V_CC drops below ~0.8V - no enable pin, biasing, or external components are needed. The internal circuitry detects V_CC loss and disables all outputs within nanoseconds, limiting leakage to <5μA even with inputs or outputs held at 5.5V.

Are Schmitt-trigger inputs enabled on all six channels?

Yes. All six inputs (1A–6A) have identical Schmitt-trigger characteristics with typical hysteresis of 0.6V at V_CC = 3V, as confirmed in the Noise Characteristics table. This applies uniformly across temperature (-40°C to +125°C) and supply voltage (2.0V–5.5V), ensuring consistent noise rejection on every channel.
