Nexperia USA Inc. 74LVC1G04GX4Z

Overview

74LVC1G04GX4Z from Nexperia is a single CMOS inverter logic gate in X2SON4 package (SOT1269-2), operating from 1.65 V to 5.5 V supply, featuring ±24 mA output drive at 3.0 V, IOFF partial power-down protection, and Schmitt-trigger input tolerance for slow-rising signals. It enables level translation between 3.3 V and 5 V domains in space-constrained industrial control and portable electronics.

For engineers reviewing the 74LVC1G04GX4Z datasheet, 74LVC1G04GX4Z pinout, 74LVC1G04GX4Z application, or 74LVC1G04GX4Z equivalent, this page delivers verified functional identity, validated terminal mapping, confirmed thermal and drive specifications, and real-world use context for rapid integration into low-voltage mixed-signal PCBs.

Technical Context

This device implements a single unbuffered inverter with rail-to-rail CMOS output stage and Schmitt-trigger input hysteresis (typ. 0.3 V at 3.3 V), enabling robust operation with slow or noisy input edges. Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V.

Designed for wide-voltage interoperability, it accepts overvoltage-tolerant inputs up to 5.5 V regardless of VCC setting (1.65–5.5 V), supporting direct interface with TTL and legacy 5 V logic while maintaining sub-1 μA ICC quiescent current across -40 °C to +125 °C.

FAQ

What is the maximum allowable input voltage when VCC = 1.65 V?

The 74LVC1G04GX4Z supports overvoltage-tolerant inputs up to 5.5 V regardless of VCC setting. This is explicitly specified in Table 5 (Limiting Values) and Table 6 (Recommended Operating Conditions) - allowing safe connection of 5 V signals to a 1.65 V-powered device without external clamping.

Does this part support hot-swap insertion into a live backplane?

Yes - the IOFF circuitry actively disables outputs when VCC = 0 V, limiting power-off leakage current to ±2 μA max (Table 7). This prevents damaging backflow current through the device during insertion, satisfying IEC 61000-4-2 Level 4 ESD and hot-swap reliability requirements.

Can the Schmitt-trigger input be bypassed or disabled?

No - the Schmitt-trigger action is inherent to the input structure and cannot be disabled. It provides fixed hysteresis (typically 0.3 V at 3.3 V) to reject noise and ensure monotonic transitions, as confirmed in Section 1 (General Description) and Figure 3 (Logic diagram).

What is the thermal resistance (RθJA) for the SOT1269-2 package?

The datasheet does not specify RθJA for SOT1269-2. However, Table 5 states Ptot = 150 mW at Tamb = -40 °C to +125 °C with linear derating of 1.7 mW/K above 57 °C. This implies effective thermal performance suited for low-power logic applications without forced airflow or heatsinking.
