Nexperia USA Inc. 74HC04D,652

Overview

74HC04D,652 from Nexperia is a CMOS hex inverter IC operating from 2.0 V to 6.0 V supply, delivering six independent high-noise-immunity logic inversions with propagation delay as low as 7 ns at VCC = 6.0 V and CL = 50 pF. It features input clamp diodes enabling safe interfacing to voltages exceeding VCC using current-limiting resistors, and is rated for operation from −40 °C to +125 °C in the SO14 (SOT108-1) package.

For engineers reviewing the 74HC04D,652 datasheet, 74HC04D,652 pinout, 74HC04D,652 application, or 74HC04D,652 equivalent, this device serves as a general-purpose logic-level inversion solution in digital control, signal conditioning, clock buffering, and bus driving circuits where low power, wide voltage tolerance, and robust ESD immunity (HBM >2000 V) are required.

Technical Context

The 74HC04D,652 implements six identical CMOS inverter stages in a single monolithic die, each with symmetrical push-pull output drivers capable of sourcing/sinking ±25 mA. Its inputs accept CMOS-level thresholds (VIH ≥ 0.7×VCC, VIL ≤ 0.3×VCC), ensuring compatibility across 2.0–6.0 V logic families.

Designed for noise-resilient digital systems, it incorporates on-chip input clamp diodes to safely shunt overvoltage transients, supports rail-to-rail output swing (VOH ≥ VCC − 0.1 V, VOL ≤ 0.16 V at VCC = 6.0 V), and maintains stable timing performance across temperature (−40 °C to +125 °C) and supply variation.

FAQ

What is the maximum clock frequency supported by the 74HC04D,652?

The 74HC04D,652 does not specify a maximum clock frequency, but its typical propagation delay of 7 ns at VCC = 6.0 V and CL = 50 pF implies reliable operation up to approximately 50 MHz in non-critical timing paths. For synchronous clock distribution, design margins should limit usage to ≤30 MHz to accommodate worst-case delay, temperature, and voltage variations.

Can the 74HC04D,652 drive a 50 Ω transmission line directly?

No - the 74HC04D,652 is not designed for 50 Ω line driving. Its output impedance is ~50–100 Ω (typ), resulting in significant reflections and overshoot on 50 Ω traces. Use a dedicated line driver (e.g., SN74LVC1G04 with controlled impedance) or add series termination (33–47 Ω) close to the output pin for short runs (<10 cm) at low frequencies.

Is the 74HC04D,652 suitable for automotive applications?

The 74HC04D,652 is qualified for −40 °C to +125 °C operation and meets AEC-Q100 stress test requirements for temperature cycling and HBM ESD, but Nexperia does not classify it as an automotive-qualified part. For safety-critical or ASIL-rated systems, use the explicitly automotive-qualified variant 74HC04-Q100 (SOT108-1) instead.

How should unused inputs be handled on the 74HC04D,652?

All six inputs must be terminated - either tied HIGH to VCC or LOW to GND through ≤10 kΩ resistors. Floating inputs cause increased ICC, erratic switching, and potential thermal overstress due to partial conduction in the input CMOS pair. Never leave any 1A–6A pins unconnected.
