Diodes Incorporated 74LV04AT14-13

Overview

74LV04AT14-13 from Diodes Incorporated is a TSSOP-14 packaged hex inverter IC with six independent CMOS push-pull inverters, 2.0V–5.5V supply range, 5.5V-tolerant inputs, and IOFF-enabled partial power-down protection. It supports voltage translation between 3.3V and 5V logic domains and delivers 12mA output drive at 4.5V.

For engineers reviewing the 74LV04AT14-13 datasheet, 74LV04AT14-13 pinout, 74LV04AT14-13 application, or 74LV04AT14-13 equivalent, key selection criteria include input voltage tolerance, IOFF leakage (<5μA), propagation delay (3.6ns typ @5V/CL=15pF), Schmitt-trigger input hysteresis, and TSSOP-14 thermal performance in space-constrained logic isolation designs.

Technical Context

The 74LV04AT14-13 implements six identical inverting gates with true CMOS architecture, each performing Y = A̅. Its IOFF circuit disables outputs during VCC = 0V to prevent back-current flow in mixed-voltage or hot-swap systems.

All inputs feature Schmitt-trigger action with hysteresis (VIH(D) = 2.31V, VIL(D) = 0.99V @3V), enabling robust noise immunity in noisy digital environments. Input clamp current exceeds ±20mA, and latch-up immunity meets JESD78 Class I (>100mA).

FAQ

What is the maximum input voltage the 74LV04AT14-13 can safely accept?

The 74LV04AT14-13 accepts input voltages up to 5.5V regardless of VCC level - verified per Absolute Maximum Ratings (VI = –0.5V to +7.0V) and Recommended Operating Conditions (VI = 0 to 5.5V). This allows direct connection of 5V signals even when powered from 2.0V or 3.3V, enabling robust voltage translation without external components.

Does the 74LV04AT14-13 support partial power-down operation?

Yes - the device integrates an IOFF circuit that disables all outputs when VCC = 0V, limiting output leakage to <5μA. This prevents damaging back-current flow from live inputs into a powered-down supply rail, satisfying JEDEC JESD78 Class I latch-up immunity and supporting hot-swap and multi-rail sequencing requirements.

How does the Schmitt-trigger input improve noise immunity?

Schmitt-trigger inputs provide hysteresis: VIH(D) = 2.31V and VIL(D) = 0.99V at VCC = 3V, yielding 1.32V of input threshold separation. This prevents oscillation on slow or noisy edges (e.g., mechanical switches, long traces), eliminating need for external RC filtering while maintaining deterministic logic transitions under EMI stress.

Can unused inputs be left floating?

No - unused inputs must be tied to VCC or GND per datasheet Note 5. Floating CMOS inputs cause increased ICC, unpredictable output states, and potential oscillation due to noise coupling. Tying to rail ensures stable logic levels, minimizes power consumption, and avoids unintended switching that could affect adjacent channels or system timing margins.
