NXP Semiconductors 74LVC3G04GD,125

Overview

74LVC3G04GD,125 from Nexperia is a triple CMOS inverter IC with Schmitt-trigger inputs, 1.65 V to 5.5 V supply range, ±24 mA output drive at 3.0 V, IOFF partial power-down protection, and operation from –40 °C to +125 °C. It serves as a level translator and signal conditioner in mixed-voltage logic interfaces, such as 3.3 V microcontroller GPIO driving 5 V peripheral enable lines.

For engineers reviewing the 74LVC3G04GD,125 datasheet, 74LVC3G04GD,125 pinout, 74LVC3G04GD,125 application, or 74LVC3G04GD,125 equivalent, key selection criteria include input threshold compatibility across voltage domains, IOFF-enabled bus isolation during power sequencing, propagation delay stability over temperature, and XSON8 package suitability for high-density PCB layouts.

Technical Context

This device implements three independent inverting buffers with Schmitt-trigger inputs-each providing hysteresis (typically 0.3–0.5 V) to reject slow-rising noise on control signals. The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current from live buses into unpowered sections.

It complies with JEDEC standards JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), and JESD8B/JESD36 (2.7–3.6 V), enabling interoperability across legacy and modern logic families. Input tolerance up to 5.5 V allows direct connection to 5 V TTL outputs without external resistors.

FAQ

Does 74LVC3G04GD,125 support 5 V input signals while powered from 1.8 V?

Yes. Its inputs are 5 V tolerant across the full 1.65–5.5 V supply range, allowing direct connection to 5 V TTL or LVTTL outputs without clamping diodes or level-shifters. This is confirmed in Table 6 (Recommended Operating Conditions) and Section 1 (General Description) of the datasheet.

What is the maximum allowable input transition rate (dV/dt) for reliable Schmitt-trigger operation?

The datasheet specifies Δt/ΔV limits: ≤20 ns/V at VCC = 1.65–2.7 V and ≤10 ns/V at VCC = 2.7–5.5 V. For a 1.8 V supply, input edges must be faster than 36 ns; for 3.3 V, faster than 33 ns - ensuring hysteresis reliably suppresses ringing-induced false triggering.

Can 74LVC3G04GD,125 drive a 50 Ω transmission line directly?

No. With ±24 mA drive at 3.0 V, its output impedance is ~125 Ω (calculated from VOH/VOL vs. load), making it unsuitable for direct 50 Ω line driving. It requires a series termination resistor (e.g., 33 Ω) or dedicated line driver for controlled-impedance signaling.

Is the XSON8 package of 74LVC3G04GD,125 compatible with standard reflow profiles?

Yes. The SOT996-2 package is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), supporting peak reflow temperatures up to 260 °C. Its 0.35 mm height and wettable flanks ensure reliable solder joint formation under standard lead-free profiles.
