Product details
Overview
74HC04D/AUJ from Nexperia is a hex CMOS inverter IC operating across 2.0 V to 6.0 V supply, delivering six independent logic inversion functions with propagation delay as low as 7 ns at VCC = 6.0 V and CL = 50 pF. It features input clamp diodes for overvoltage-tolerant interfacing, ±25 mA output drive capability, and operates from -40 °C to +125 °C - commonly deployed in digital signal conditioning, level translation, and clock buffering in industrial control and embedded microcontroller systems.
For engineers reviewing the 74HC04D/AUJ datasheet, 74HC04D/AUJ pinout, 74HC04D/AUJ application, or 74HC04D/AUJ equivalent, this page delivers verified package mapping (SO14/SOT108-1), confirmed static/dynamic electrical parameters, functional pin roles, real-world use cases, and two validated alternative parts - all extracted from Nexperia's official Rev. 10 product data sheet dated 16 February 2024.
Technical Context
The 74HC04D/AUJ implements six identical CMOS inverter stages in a single monolithic die, each with symmetrical push-pull output structure enabling rail-to-rail switching and high noise immunity. Its inputs accept CMOS-level logic thresholds (VIH ≥ 3.15 V at VCC = 4.5 V; VIL ≤ 1.35 V), and include integrated clamp diodes allowing safe interface to signals exceeding VCC when used with current-limiting resistors.
It complies with JEDEC JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V) standards, supports latch-up immunity >100 mA per JESD78 Class II Level B, and meets HBM ESD >2000 V and CDM ESD >1000 V per JS-001/JS-002. The device is specified across -40 °C to +125 °C ambient temperature with guaranteed performance under recommended operating conditions.
Key Specifications

FAQ
What is the maximum supply voltage rating for the 74HC04D/AUJ?
The absolute maximum supply voltage (VCC) for the 74HC04D/AUJ is +7.0 V, as defined in Table 4 (Limiting Values) of the Nexperia datasheet Rev. 10. However, the recommended operating range is 2.0 V to 6.0 V. Operating continuously at 7.0 V risks permanent damage and violates the Absolute Maximum Rating System per IEC 60134. For reliable long-term operation, maintain VCC ≤ 6.0 V.
Does the 74HC04D/AUJ support 3.3 V logic systems?
Yes, the 74HC04D/AUJ fully supports 3.3 V operation: its recommended VCC range includes 3.3 V, input thresholds (VIH ≥ 2.1 V, VIL ≤ 1.35 V at VCC = 4.5 V; scaled proportionally at 3.3 V) provide adequate noise margin, and output VOH/VOL meet 3.3 V CMOS levels. It is widely used in mixed-voltage boards interfacing 3.3 V MCUs with 5 V peripherals.
What is the purpose of the input clamp diodes in the 74HC04D/AUJ?
The input clamp diodes in the 74HC04D/AUJ allow safe interfacing to input signals exceeding VCC - for example, when connecting a 5 V signal to a 3.3 V-powered 74HC04D/AUJ. When used with an external series current-limiting resistor, these diodes shunt excess voltage to VCC or GND, preventing damage without requiring additional protection circuitry.
Can the 74HC04D/AUJ drive a 50 pF load with sub-10 ns propagation delay?
Yes - at VCC = 6.0 V and CL = 50 pF, the 74HC04D/AUJ achieves a typical propagation delay (tpd) of 7 ns, with a maximum of 22 ns over the full -40 °C to +125 °C temperature range (Table 7). This makes it suitable for medium-speed digital paths such as clock distribution, address/data bus conditioning, and synchronous control signal routing.
Is the 74HC04D/AUJ pin-compatible with the 74HCT04D?
Yes, the 74HC04D/AUJ and 74HCT04D share identical SO14 (SOT108-1) packaging and pinout - including the same 14-pin arrangement, terminal functions (1A–6A, 1Y–6Y, GND, VCC), and mechanical dimensions. They differ only in input threshold specifications (CMOS vs. TTL), allowing direct substitution where interface voltage compatibility is verified.
