Product details
Overview
MC74VHC08DTR2 from onsemi is a quad 2-input AND gate IC in TSSOP-14 package, operating from 2.0 V to 5.5 V, with typical propagation delay of 4.3 ns at 5.0 V and CMOS-level input compatibility. It delivers high noise immunity (28% of VCC), low dynamic output noise (VOLP ≤ 0.8 V), and supports 3.3 V/5.0 V level translation in mixed-voltage logic systems.
For engineers reviewing the MC74VHC08DTR2 datasheet, pinout, applications, or equivalent options, key selection considerations include its 5.5 V-tolerant inputs, AEC-Q100 qualified −Q variant availability, guaranteed operation down to –55°C, and compatibility with standard TTL and CMOS logic families in industrial control and automotive interface circuits.
Technical Context
The MC74VHC08DTR2 implements four independent 2-input AND gates using silicon-gate CMOS technology, with three-stage internal circuitry including a buffered output stage for enhanced noise immunity and stable switching. Its input structure tolerates up to 5.5 V regardless of VCC, enabling safe interfacing between 3 V and 5 V subsystems.
It features full 5.0 V CMOS-level output swings, balanced tPLH/tPHL propagation delays, and power-down protection-ensuring robust behavior during supply sequencing or hot-insertion scenarios without external clamping components.

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 |
|---|---|---|---|
| SN74LVC08APW | Lower VCC range (1.65–5.5 V); 3.3 ns typ tPD at 3.3 V; 5 V-tolerant inputs only up to 5.5 V when VCC ≥ 2.3 V | Better suited for 3.3 V-centric designs with tighter timing budgets; less robust for 2.0 V operation or wide-VCC variation | Select when primary supply is 3.3 V and lowest possible propagation delay is critical; verify input tolerance constraints match system voltage sequencing. |
| 74AHC08PW | Higher drive strength (±8 mA @ 5 V); identical 2.0–5.5 V range; 4.0 ns typ tPD; same TSSOP-14 footprint | Superior noise immunity (VNIH/VNIL = 30%) and lower VOLP (0.6 V max); preferred for high-noise industrial environments | Choose for improved EMI resilience and faster edge rates where board-level noise margins are marginal; pin-compatible upgrade path. |
Compared with SN74LVC08APW and 74AHC08PW, the MC74VHC08DTR2 offers broader minimum supply support (2.0 V), stronger input overvoltage tolerance under low-VCC conditions, and AEC-Q100 qualification for automotive use - making it optimal for mixed-voltage, extended-temperature, and safety-relevant designs.

FAQ
What is the maximum input voltage rating for MC74VHC08DTR2?
The MC74VHC08DTR2 supports DC input voltages from –0.5 V to +6.5 V, independent of VCC. This 5.5 V-tolerant input capability allows safe interfacing with 5 V signals even when the device is powered from 3.3 V or 2.5 V supplies - a key feature confirmed in the Absolute Maximum Ratings table of the official datasheet.
Does MC74VHC08DTR2 support operation at 2.0 V supply?
Yes, MC74VHC08DTR2 is fully specified to operate from 2.0 V to 5.5 V, with guaranteed functionality across the full –55°C to +125°C temperature range at 2.0 V. The Recommended Operating Conditions table explicitly lists 2.0 V as the minimum VCC, and DC/AC electrical characteristics include test data at this voltage.
Is MC74VHC08DTR2 pin-compatible with TTL logic devices?
MC74VHC08DTR2 is functionally and pin-compatible with standard 74-series TTL AND gates (e.g., 74LS08), but not electrically identical: its inputs are CMOS-compatible (VIH ≈ 0.7×VCC), unlike TTL's fixed VIH ≈ 2.0 V. For true TTL-level input compatibility, the MC74VHCT08A variant should be used instead.
What is the thermal resistance (θJA) of MC74VHC08DTR2 in TSSOP-14 package?
The MC74VHC08DTR2 in TSSOP-14 (Case 948G) has a junction-to-ambient thermal resistance (θJA) of 150°C/W, measured per JESD51-7 on a standard FR4 board with 2-ounce copper. This value is critical for calculating junction temperature rise under load and ensuring reliable operation at elevated ambient temperatures.
Can MC74VHC08DTR2 be used in automotive applications?
Yes - the MC74VHC08DTR2G−Q* variant is AEC-Q100 qualified and PPAP capable, meeting automotive grade 1 requirements (–40°C to +125°C). While the base MC74VHC08DTR2 is not automotive-qualified, the −Q suffix version shares identical electrical and mechanical specifications with added process and traceability controls for automotive use.
