Product details

Overview

MC74LCX04D from onsemi is a low-voltage CMOS hex inverter with 5 V-tolerant inputs, operating from 1.65 V to 5.5 V supply. It delivers 24 mA balanced output sink/source capability at 3.0 V, features near-zero static supply current (10 µA), and supports automotive-grade reliability via AEC-Q100 qualification. It is used in level-shifting logic interfaces between 3.3 V/2.5 V systems and legacy 5 V TTL buses.

For engineers reviewing the MC74LCX04D datasheet, pinout, applications, or equivalent options, key selection considerations include 5 V input tolerance under sub-5 V V_CC, propagation delay ≤5.2 ns at 3.3 V, ±24 mA drive strength, thermal resistance of 150 °C/W in TSSOP-14, and AEC-Q100 qualification for automotive control modules.

Technical Context

The MC74LCX04D implements six independent CMOS inverter stages in a single monolithic IC, each with high-impedance TTL-compatible inputs and rail-to-rail CMOS outputs. Its input structure enables safe interfacing with 5 V logic while powered from as low as 1.65 V, eliminating external level shifters in mixed-voltage designs.

It operates across −40 °C to +125 °C with latchup immunity >100 mA and ESD robustness >2000 V HBM. The device exhibits matched propagation delays (t_PLH/t_PHL) and low output skew (<1.0 ns) across all six channels at 3.0–3.6 V, supporting synchronous signal inversion in timing-critical paths.

Equivalent & Alternatives

The following parts are listed as comparable options for similar hex inverter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC04APWR	Same 1.65–5.5 V range and 5 V-tolerant inputs; slightly higher t_PLH/t_PHL (6.5 ns @ 3.3 V) and lower drive (±24 mA only at V_CC ≥ 4.5 V).	Not AEC-Q100 qualified; intended for commercial/industrial use only.	Select SN74LVC04APWR for cost-sensitive non-automotive designs where AEC-Q100 compliance is unnecessary.
74AHC04PW,118	Wider V_CC range (2–5.5 V); no 5 V input tolerance below 4.5 V V_CC; higher propagation delay (8.5 ns @ 3.3 V) and lower drive (±8 mA @ 3.3 V).	Higher static current (100 µA) and no automotive qualification; suited for general-purpose logic in legacy 5 V systems.	Choose 74AHC04PW,118 only if existing 5 V-only designs require drop-in replacement with minimal layout change.

Compared with SN74LVC04APWR and 74AHC04PW,118, the MC74LCX04D uniquely combines AEC-Q100 qualification, guaranteed 24 mA drive down to 3.0 V, and sub-5.2 ns propagation at 3.3 V - making it the sole option for automotive-grade, low-voltage, high-drive hex inversion.

FAQ

What is the maximum input voltage rating for MC74LCX04D when V_CC = 3.3 V?

The MC74LCX04D supports DC input voltages up to 5.5 V regardless of V_CC level, enabling safe interfacing with 5 V TTL outputs even when powered from 3.3 V. Absolute maximum input voltage is 6.5 V, but sustained operation above 5.5 V violates the recommended operating conditions and risks reliability degradation. This 5 V-tolerance is implemented via internal input protection diodes and verified across −40 °C to +125 °C.

Does MC74LCX04D support operation at 1.8 V supply voltage?

Yes, MC74LCX04D is fully specified to operate at V_CC = 1.8 V, with guaranteed performance including t_PLH/t_PHL ≤10 ns and ±24 mA output drive at 3.0 V (derated linearly at lower V_CC). The device meets all DC and AC electrical characteristics down to 1.65 V, making it suitable for ultra-low-power 1.8 V microcontroller peripheral interfaces and battery-operated sensor nodes.

Is MC74LCX04D pin-compatible with standard 74HC04 or 74LS04 packages?

No, MC74LCX04D is not pin-compatible with 74HC04 or 74LS04 in SOIC-14 or DIP-14 packages due to different pin assignments: MC74LCX04D uses alternating input-output layout (A0-O0-A1-O1…), whereas 74HC04 places all inputs on one side and outputs on the other. However, the TSSOP-14 variant of MC74LCX04D matches the 74HC04 footprint pitch (0.65 mm vs 1.27 mm), so PCB redesign is required for direct substitution.

What packaging options are available for MC74LCX04D?

The MC74LCX04D is available exclusively in TSSOP-14 (Case 948G) per the ordering code MC74LCX04DTR2G−Q*, with Pb-free finish and tape-and-reel packaging (2500 units per reel). While the broader MC74LCX04 family includes SOIC-14 variants (e.g., MC74LCX04DG), the "D" suffix specifically denotes the TSSOP-14 automotive-grade version with −Q qualification and PPAP support.

How does the latchup immunity of MC74LCX04D compare to standard CMOS logic devices?

MC74LCX04D exceeds 100 mA latchup immunity per JEDEC JESD78, significantly higher than typical 74HC or 74AHC series devices (typically 50–80 mA). This enhanced robustness is achieved through specialized substrate guard ring design and process hardening, making MC74LCX04D suitable for automotive environments where electrical transients and ESD events are frequent. Test data confirms no latchup observed up to 120 mA injected per I/O pin.
