Nexperia USA Inc. 74HCT04D-Q100,118

Overview

74HCT04D-Q100,118 from Nexperia is an AEC-Q100 Grade 1 qualified hex inverter IC with TTL-compatible inputs, operating from 4.5 V to 5.5 V supply, delivering propagation delay as low as 8 ns at 5 V/15 pF, and rated for -40 °C to +125 °C ambient. It features six independent inverters in a 14-lead SOIC package (SOT108-1), used for signal conditioning, level translation, and clock buffering in automotive body control modules.

For engineers reviewing the 74HCT04D-Q100,118 datasheet, 74HCT04D-Q100,118 pinout, 74HCT04D-Q100,118 application, or 74HCT04D-Q100,118 equivalent, key selection criteria include TTL input compatibility, automotive temperature range compliance, SO14 package mechanical fit, and guaranteed 4 mA output drive at 5 V.

Technical Context

This device implements six independent CMOS-based inverting buffers with Schmitt-trigger–free inputs optimized for TTL-level logic thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5 V). Each inverter exhibits matched propagation delays (tpd ≤ 29 ns over full temperature range) and transition times (tt ≤ 22 ns), supporting clean digital waveform inversion without added hysteresis.

The SO14 package (SOT108-1) provides standard lead pitch (1.27 mm), 3.9 mm body width, and integrated input clamp diodes enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors - critical for mixed-voltage domain isolation in automotive ECUs.

FAQ

Is 74HCT04D-Q100,118 pin-compatible with standard 74HCT04 SOIC packages?

Yes. It uses the industry-standard SOT108-1 (SO14) footprint with identical pin 1 location, VCC (pin 14), GND (pin 7), and I/O assignment (e.g., input 1A on pin 1, output 1Y on pin 2). Mechanical dimensions and solder pad layout match JEDEC MS-012, enabling drop-in replacement in existing designs.

What is the maximum output current per channel at 125 °C ambient?

At VCC = 4.5 V and Tamb = +125 °C, the device guarantees IO = ±4.0 mA while maintaining VOH ≥ 3.7 V and VOL ≤ 0.4 V per output, as specified in Table 6 of the Rev. 5 datasheet. Derating is not required below this limit due to built-in thermal design margin.

Can 74HCT04D-Q100,118 drive a 50 pF capacitive load at 10 MHz?

Yes. With CL = 50 pF and f = 10 MHz, dynamic power is PD ≈ 24 pF × (4.5 V)² × 10 MHz = ~48.6 mW - well below the 500 mW total package limit (SOT108-1) and within safe thermal limits given its 10.1 mW/K derating slope above 100 °C.

Does this part support 3.3 V logic interfacing?

No. The 74HCT04 variant is specified only for 4.5–5.5 V operation. For 3.3 V systems, use the 74HC04D-Q100 (CMOS-input version) or 74LVC04 (3.3 V tolerant), both available in AEC-Q100 Grade 1 variants - neither is electrically compatible with this HCT part's input thresholds.
