Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC08QPWRQ1 | TI AEC-Q100 Grade 1 part; identical 2–6 V supply, but tPLH = 19 ns @ 6 V (vs. 13 ns for MC74HC08ADTR2G-Q) | Valid for automotive use but slower propagation limits high-speed sampling circuits | Select when TI supply chain alignment is prioritized over minimal propagation delay |
| 74HC08D,118 | Nexperia SOIC-14 version; same logic and DC specs, but not AEC-Q100 qualified and rated only to +85 °C | Suitable for commercial/industrial use only - not approved for automotive under-hood placement | Choose for cost-sensitive non-automotive designs where extended temperature is not required |
Compared with SN74HC08QPWRQ1 and 74HC08D,118, the MC74HC08ADTR2G-Q delivers the fastest propagation (13 ns), full AEC-Q100 Grade 1 qualification, and TSSOP-14 footprint - making it optimal for space-constrained, safety-critical automotive logic gating where timing and reliability are jointly essential.

FAQ
What is the maximum operating temperature range for the MC74HC08ADTR2G-Q?
The MC74HC08ADTR2G-Q is rated for −55 °C to +125 °C operating free-air temperature, meeting AEC-Q100 Grade 1 requirements. This range is validated across all DC and AC parameters in the official datasheet, including propagation delay, output drive, and input thresholds - ensuring reliable operation in under-hood automotive locations and industrial enclosures without forced cooling.
Is the MC74HC08ADTR2G-Q pin-compatible with standard LS08 devices?
Yes, the MC74HC08ADTR2G-Q is identical in pinout to the 74LS08, as explicitly stated in the datasheet. All 14 pins - including VCC (Pin 14), GND (Pin 7), and the four A/B/Y signal pairs - match LS08 layout. However, note that while pinout aligns, electrical behavior differs: MC74HC08ADTR2G-Q operates at 2.0–6.0 V and offers CMOS input compatibility, unlike bipolar LS08's 5 V-only and TTL-level inputs.
Does the MC74HC08ADTR2G-Q support mixed-voltage interfacing with TTL logic?
Yes - the MC74HC08ADTR2G-Q inputs are compatible with standard CMOS outputs natively, and with pullup resistors, they interface directly to LSTTL outputs. Its VIH minimum of 4.20 V and VIL maximum of 1.80 V at 6.0 V supply provide sufficient margin for TTL logic high (2.4 V min) and low (0.8 V max), enabling seamless integration into legacy TTL-based subsystems without level shifters.
What is the propagation delay of the MC74HC08ADTR2G-Q at 5.0 V supply?
At VCC = 5.0 V and −55 °C to +25 °C, the MC74HC08ADTR2G-Q has a maximum propagation delay (tPLH/tPHL) of 15 ns, as specified in the AC Characteristics table. This value is measured from input transition (50% point) to output transition (50% point) under 50 pF load and 1 kΩ termination, confirming suitability for 30+ MHz digital control loops in automotive and industrial timing-critical applications.
How does the −Q suffix affect the MC74HC08ADTR2G-Q compared to non-Q variants?
The −Q suffix on MC74HC08ADTR2G-Q indicates automotive qualification: it is AEC-Q100 Grade 1 certified, PPAP capable, and manufactured under unique site and control change requirements. Unlike standard MC74HC08ADTR2G, the −Q version undergoes additional stress testing, lot traceability, and process controls - ensuring consistent performance and reliability for automotive safety-critical functions such as body control and powertrain interlocks.
