Diodes Incorporated 74LVC06AS14-13

Overview

74LVC06AS14-13 from Diodes Incorporated is a hex inverter IC with six independent open-drain outputs, designed for level-shifting and wired-logic applications across 1.65V–5.5V supply rails. It sinks up to 24mA at 3.3V, supports IOFF partial power-down, and features 5.5V-tolerant inputs-enabling use in mixed-voltage systems such as USB peripheral interfaces and I²C bus extenders.

For engineers reviewing the 74LVC06AS14-13 datasheet, 74LVC06AS14-13 pinout, 74LVC06AS14-13 application, or 74LVC06AS14-13 equivalent, key selection criteria include open-drain drive strength, IOFF leakage (<20 µA), input voltage tolerance (up to 5.5V), and SO-14 thermal resistance (θJA TBD).

Technical Context

This device implements six identical CMOS inverters with open-drain outputs, enabling active-low wired-OR and active-high wired-AND configurations. Each gate accepts inputs up to 5.5V regardless of VCC, supporting bidirectional voltage translation between 1.8V, 3.3V, and 5V domains.

The IOFF circuit disables output FETs when VCC = 0V, limiting back-drive current to ≤20 µA and preventing damage during hot-insertion or partial power-down. Propagation delay ranges from 1.7 ns (5V) to 7.6 ns (1.65V) under loaded conditions.

Key Specifications

Pinout & Package

FAQ

Can 74LVC06AS14-13 drive an LED directly?

Yes-it can sink up to 24mA at 3.3V, sufficient for standard 20mA LEDs. Connect the LED anode to VCC via a current-limiting resistor and cathode to any output pin. Ensure VCC matches the LED forward voltage requirement and verify total package power dissipation remains below 500mW under full-load conditions.

Does this device support I²C bus arbitration?

No-it lacks built-in bus arbitration logic. However, its open-drain outputs are electrically compatible with I²C SDA/SCL lines when used as a buffer or level shifter. External pull-ups and master arbitration remain unchanged; the device simply repeats inverted logic states without altering protocol behavior.

What happens if VCC is disconnected while inputs remain at 5V?

The IOFF circuit activates automatically, disabling output FETs and limiting back-current to ≤20 µA. Inputs remain protected up to 5.5V, and no latch-up occurs (JESD78 Class II, >250mA). This enables safe hot-plug operation in modular systems without additional protection circuitry.

Is there a version with internal pull-up resistors?

No-the 74LVC06A series has no internal pull-ups. All outputs are pure open-drain and require external pull-up resistors. For integrated pull-ups, consider Diodes' 74LVC1G06 with external resistor or dedicated I²C buffer ICs like PI4ULS5V102.
