Diodes Incorporated 74LV06AT14-13

Overview

74LV06AT14-13 from Diodes Incorporated is a hex inverter IC with six independent open-drain outputs, designed for level translation and signal isolation in mixed-voltage systems (2.0V–5.5V supply). It features 5.5V-tolerant inputs, IOFF partial power-down protection, Schmitt-trigger inputs, and sinks up to 12mA at VCC = 4.5V. Used in PC peripherals, set-top boxes, and hard drive controllers for logic-level conversion and power-down signal gating.

For engineers reviewing the 74LV06AT14-13 datasheet, 74LV06AT14-13 pinout, 74LV06AT14-13 application, or 74LV06AT14-13 equivalent, key selection criteria include open-drain drive capability, 5.5V input tolerance, IOFF-enabled backflow prevention during partial power-down, Schmitt-trigger noise immunity, and TSSOP-14 thermal and board-space efficiency.

Technical Context

The 74LV06AT14-13 implements six identical inverting buffers with open-drain outputs, requiring external pull-up resistors for high-level assertion. Its IOFF circuit disables output leakage when VCC = 0V, enabling safe hot-insertion and bus isolation in multi-rail systems.

All six channels feature Schmitt-trigger inputs (VIH(D) = 2.31V, VIL(D) = 0.99V at VCC = 3V), ensuring robust noise rejection across supply voltages. Propagation delay ranges from 2.2ns (VCC = 5.0V, CL = 15pF) to 10.4ns (VCC = 2.5V, CL = 15pF), supporting timing-critical interface buffering up to ~100 MHz.

FAQ

Can 74LV06AT14-13 be used as a level shifter between 3.3V and 5V systems?

Yes - its 5.5V-tolerant inputs accept 5V signals while operating from a 3.3V supply, and its open-drain outputs can be pulled up to 5V, enabling bidirectional level translation for control signals like reset or interrupt lines without additional components.

Does 74LV06AT14-13 support I²C bus operation?

Yes - its six open-drain outputs meet I²C electrical requirements when externally pulled up to the bus voltage (e.g., 3.3V or 5V), and its low VOL (0.55V max at 12mA) ensures valid LOW-level signaling compatible with standard I²C receivers.

What happens to the outputs during power-down (VCC = 0V)?

The IOFF circuit actively disables all outputs, limiting leakage current to ≤5μA even when inputs or outputs are biased to 5.5V - preventing back-current flow that could damage upstream drivers or disrupt powered-down subsystems.

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

Yes - each Y output requires an external pull-up resistor to the desired HIGH-level voltage (e.g., 3.3V or 5V). Typical values range from 1kΩ (for fast rise times and 12mA drive) to 10kΩ (for low power), selected based on bus capacitance and speed requirements.
