Product details
Overview
MC74HCT04ADTR2G-Q from onsemi is a hex inverter IC with TTL-compatible inputs, operating at 4.5–5.5 V supply, delivering 4 mA output drive per inverter, and qualified to AEC-Q100 for automotive use. It contains six independent three-stage inverters in a TSSOP-14 package and is used for logic-level translation and signal conditioning in engine control units and body electronics.
For engineers reviewing the MC74HCT04ADTR2G-Q datasheet, pinout, applications, or equivalent options, key selection criteria include its 5 V TTL input compatibility, 19 ns max propagation delay at 125°C, −55°C to +125°C operating range, and automotive-grade qualification status.
Technical Context
The MC74HCT04ADTR2G-Q implements six identical CMOS-based three-stage inverter circuits, each with buffered output stages to ensure consistent switching behavior across temperature and voltage. Its input threshold is fixed at 2.0 V (VIH) and 0.8 V (VIL), matching standard TTL logic levels without external biasing.
It operates strictly within 4.5–5.5 V, draws ≤40 µA quiescent current at 125°C, and maintains output voltage compliance (VOH ≥3.98 V, VOL ≤0.26 V at 4.0 mA load) across the full industrial temperature range. Input capacitance is capped at 10 pF, supporting high-speed digital interfacing.
Key Specifications

|---|---|
| Supply Voltage | 4.5–5.5 V - Ensures compatibility with 5 V TTL and microcontroller I/O rails without level-shifting. |
| Propagation Delay | 19 ns max at 125°C - Enables reliable timing in real-time automotive control loops up to ~25 MHz toggle rate. |
| Output Drive | ±4.0 mA per inverter - Sufficient to directly drive LSTTL loads or small capacitive buses (≤50 pF). |
| Input Thresholds | VIH = 2.0 V, VIL = 0.8 V - Matches legacy TTL logic families without pull-up resistors or external biasing. |
| Operating Temp | −55°C to +125°C - Validated for under-hood and powertrain applications per AEC-Q100 Grade 1. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HCT04DR | SOIC-14 package; same electrical specs but non-automotive grade; no AEC-Q100 qualification. | Not suitable for safety-critical or under-hood automotive use; limited to consumer/industrial boards. | Select when cost sensitivity outweighs automotive qualification requirements and TSSOP footprint is not needed. |
| 74LVC04ADTR2G | Wider supply range (1.65–5.5 V); lower VIH (1.5 V @ 3.3 V); 3.3 V optimized; not AEC-Q100 qualified. | Designed for mixed-voltage 3.3 V systems; lacks high-temp validation for engine bay deployment. | Prefer for portable or infotainment subsystems where 3.3 V operation and smaller die size reduce power, but automotive qualification is unnecessary. |
Compared with SN74HCT04DR and 74LVC04ADTR2G, the MC74HCT04ADTR2G-Q provides guaranteed AEC-Q100 Grade 1 operation and TSSOP-14 space savings, making it the only choice for thermally demanding, safety-relevant automotive logic functions requiring long-term reliability and traceable qualification.

FAQ
What is the maximum operating temperature for MC74HCT04ADTR2G-Q?
The MC74HCT04ADTR2G-Q is rated for operation from −55°C to +125°C junction temperature and is AEC-Q100 Grade 1 qualified, meaning it supports ambient temperatures up to +125°C in automotive under-hood applications. This rating is verified per JEDEC JESD22-A108 and confirmed in the official onsemi datasheet Rev. 15.
Does MC74HCT04ADTR2G-Q support 3.3 V logic inputs?
No, MC74HCT04ADTR2G-Q does not reliably accept 3.3 V logic inputs. Its input thresholds are fixed at VIH = 2.0 V and VIL = 0.8 V under 4.5–5.5 V supply, optimized for 5 V TTL compatibility. Applying 3.3 V signals may result in marginal or undefined switching behavior; use 74LVC04ADTR2G instead for 3.3 V systems.
Is MC74HCT04ADTR2G-Q pin-compatible with the standard LS04?
Yes, MC74HCT04ADTR2G-Q is pinout-identical to the 74LS04 and MC14069, as confirmed in the onsemi datasheet section "Pinout (Top View)" and functional description. All six inverter inputs and outputs map one-to-one, enabling direct replacement in legacy through-hole or SOIC designs-provided the TSSOP-14 footprint is adapted.
What is the typical propagation delay of MC74HCT04ADTR2G-Q at 25°C?
The typical propagation delay of MC74HCT04ADTR2G-Q is 15 ns at VCC = 5.0 V and TA = 25°C, as specified in the AC Characteristics table for MC74HCT04A. The maximum delay is 19 ns at 125°C, ensuring timing predictability across the full automotive temperature range.
Can MC74HCT04ADTR2G-Q drive a 50 pF capacitive load at 10 MHz?
Yes, MC74HCT04ADTR2G-Q can drive a 50 pF load at 10 MHz. With 10 pF input capacitance, 19 ns max propagation delay, and 4 mA output drive, it meets rise/fall time and transition time specs (tTLH/tTHL ≤22 ns) required for clean 10 MHz square waves into 50 pF, as validated in Figure 4 switching waveforms and AC test conditions.
