onsemi MC74LVX04MG

Overview

MC74LVX04MG from onsemi is a high-speed CMOS hex inverter with 5 V-tolerant inputs, designed for level-shifting between 3.0 V and 5.0 V logic domains. It delivers 4.1 ns typical propagation delay at V_CC = 3.3 V, supports ±25 mA output drive, operates from 2.0 V to 3.6 V supply, and features input voltage tolerance up to 6.5 V - enabling robust interfacing in mixed-voltage embedded control systems.

For engineers reviewing the MC74LVX04MG datasheet, pinout, applications, or equivalent options, key selection criteria include its 5 V-tolerant input capability, low-noise performance (V_OLP ≤ 0.5 V), balanced propagation delays, latchup immunity (>300 mA), and Pb-free RoHS-compliant TSSOP-14 packaging.

Technical Context

The MC74LVX04MG implements six independent CMOS inverter stages in a single monolithic die, each with symmetrical input thresholds and rail-to-rail output swing. Its input structure incorporates protection diodes and clamping circuitry that enable safe operation with input voltages up to 6.5 V - even when V_CC is as low as 2.0 V.

Propagation delay matching across all six channels is guaranteed by design (t_OSHL/t_OSLH ≤ 1.5 ns), and the device exhibits low dynamic noise (V_OLP = 0.3 V typ) under 50 pF load conditions, making it suitable for noise-sensitive digital signal routing in compact PCB layouts.

FAQ

What is the maximum input voltage rating for MC74LVX04MG?

The MC74LVX04MG supports DC input voltages from −0.5 V to +6.5 V, independent of V_CC. This 5 V-tolerant feature allows direct connection to 5 V signal sources while operating from a 3.3 V supply - a key differentiator versus standard LVC or AHC logic families. The specification is guaranteed across −40 °C to +85 °C.

Does MC74LVX04MG require external pull-up resistors on inputs?

No, MC74LVX04MG does not require external pull-up resistors on inputs. Its CMOS inputs have negligible leakage (±1.0 µA max at V_IN = 5.5 V), and internal structure provides defined logic states when driven. Pull-ups are only needed if the driving source is open-drain or high-impedance - not due to MC74LVX04MG's input characteristics.

Can MC74LVX04MG drive a 50 pF capacitive load reliably?

Yes, MC74LVX04MG is fully characterized for 50 pF loads: t_PLH/t_PHL = 6.2 ns (typ) and 9.7 ns (max) at V_CC = 3.3 V. Its ±25 mA output drive strength ensures fast edge rates and minimal distortion, making it suitable for driving PCB traces, connectors, and multiple downstream CMOS inputs totaling up to 50 pF.

Is MC74LVX04MG pin-compatible with standard 74-series hex inverters?

MC74LVX04MG is functionally and pin-compatible with industry-standard 74HC04 and 74HCT04 in TSSOP-14 packages - same pin assignment (A0–A5 on odd pins, O0–O5 on even pins, V_CC on pin 14, GND on pin 7). However, unlike HCT, it offers 5 V-tolerant inputs at 3.3 V supply, enhancing interoperability in mixed-voltage designs.

What is the thermal performance of MC74LVX04MG in TSSOP-14 package?

MC74LVX04MG in TSSOP-14 (case 948G) has a junction-to-ambient thermal resistance (θ_JA) of 130 °C/W (typical, still air). At 2.0 µA quiescent current and moderate switching activity, junction temperature rise remains well below 10 °C - supporting reliable operation in sealed enclosures or stacked PCB assemblies without forced airflow.
