Product details
Overview
MC74VHC08DTRG-Q from onsemi is a quad 2-input AND gate IC in TSSOP-14 package, operating from 2.0 V to 5.5 V, with 4.3 ns typical propagation delay at 5.0 V and CMOS-level input compatibility. It delivers high noise immunity (28% of VCC), full 5.0 V output swing, and AEC-Q100 qualification for automotive use in logic interface and level-shifting circuits.
For engineers reviewing the MC74VHC08DTRG-Q datasheet, pinout, applications, or equivalent options, key selection criteria include its 2.0–5.5 V supply range, TTL-incompatible CMOS input thresholds, −Q automotive qualification, and TSSOP-14 thermal resistance of 150 °C/W.
Technical Context
The MC74VHC08DTRG-Q implements four independent AND gates using silicon-gate CMOS technology, with three-stage internal circuitry including a buffer output stage for enhanced noise immunity and stable drive. Its inputs tolerate up to 5.5 V, enabling safe interfacing between 3.3 V and 5.0 V systems without external level shifters.
It features power-down protection and latchup immunity exceeding 100 mA, with ESD robustness >2000 V HBM. Unlike the MC74VHCT08A variant, it uses standard CMOS input thresholds (VIH = 0.7×VCC, VIL = 0.3×VCC) and lacks TTL-level input compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input AND gate - provides four independent Boolean AND operations per device |
| Supply Voltage Range | 2.0 V to 5.5 V - supports mixed-voltage system interfacing and battery-powered 3.3 V designs |
| Propagation Delay | 4.3 ns (typ) at VCC = 5.0 V, CL = 50 pF - enables high-speed digital control and timing-critical combinational logic |
| Input Voltage Tolerance | −0.5 V to +6.5 V - allows safe connection to 5 V buses while powered from 3.3 V, preventing damage during hot insertion |
| Output Swing | Full rail-to-rail (0 V to VCC) - ensures reliable logic-level translation and noise margin in downstream CMOS loads |
| Quiescent Current | 2.0 µA (max) at TA = 25°C - enables ultra-low-power operation in always-on monitoring or standby logic paths |
| Operating Temperature | −55 °C to +125 °C - meets extended automotive ambient requirements per AEC-Q100 Grade 1 |
Pinout & Package
TSSOP-14 (Case 948G), 4.4 mm × 5.0 mm body, 0.65 mm pitch, 1.20 mm max height, Pb-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 9, 10, 12, 13 | Input (A1/B1/A2/B2/A3/B3/A4/B4) | Eight logic inputs across four AND gates - each pair (e.g., A1/B1) feeds one gate output |
| 3, 6, 8, 11 | Output (Y1/Y2/Y3/Y4) | Four buffered AND outputs - rail-to-rail CMOS drive capability with low dynamic noise (VOLP ≤ 0.8 V) |
| 7 | GND | Ground reference for all logic and power domains - must be low-impedance for noise immunity |
| 14 | VCC | Primary power supply - decoupling capacitor required within 1 cm for stable high-speed switching |
Key Features
| Feature | Design Value |
|---|---|
| High-speed CMOS performance | 4.3 ns propagation delay at 5 V matches bipolar TTL speed while retaining CMOS power efficiency |
| Wide supply voltage range | 2.0–5.5 V operation eliminates need for separate voltage rails when interfacing 3.3 V controllers to 5 V peripherals |
| Input overvoltage tolerance | Inputs withstand −0.5 V to +6.5 V - enables direct connection to 5 V I²C/SPI buses without clamping diodes |
| AEC-Q100 qualified | Automotive-grade reliability with PPAP capability - validated for under-hood and infotainment module deployment |
| Low dynamic noise | VOLP ≤ 0.8 V at CL = 50 pF - reduces crosstalk risk in dense PCB layouts with adjacent signal traces |
Applications
| Industrial PLC I/O Expansion | Automotive Body Control Module |

IC Role / Device Role / Timing Role: Safety interlock logic - implements hardware-enforced AND condition to prevent unintended actuator activation. Use Value: Adds fail-safe redundancy beyond software control, meeting ASIL-B functional safety decomposition requirements. |
| Medical Patient Monitor Interface | Test Equipment Signal Conditioning |
|
Use Scenario: Validating simultaneous readiness of analog front-end channels before initiating ADC conversion sequence. IC Role / Device Role / Timing Role: Synchronization enabler - gates clock-enable signal only when all channel calibration flags are high. Use Value: Ensures data coherency across multi-channel acquisition without adding microcontroller latency or jitter. |

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 |
|---|---|---|---|
| MC74VHC08DR2G | SOIC-14 package (116 °C/W θJA), same electrical specs and −Q qualification absent | Lacks AEC-Q100 certification and PPAP support; suitable for industrial but not automotive production | Select when board space permits larger footprint and automotive qualification is unnecessary |
| SN74LVC08APWR | TSSOP-14, 1.65–5.5 V supply, 3.9 ns tPD at 3.3 V, LVTTL-compatible inputs | Lower voltage minimum enables 1.8 V system integration; input thresholds differ (VIH = 2.0 V min at VCC = 3.3 V) | Prefer for mixed 1.8/3.3 V designs requiring tighter timing or LVTTL interoperability |
Compared with MC74VHC08DTRG-Q, MC74VHC08DR2G trades automotive compliance for SOIC thermal performance, while SN74LVC08APWR offers broader low-voltage support and faster 3.3 V operation but requires validation of input threshold compatibility in legacy 5 V systems.

FAQ
What is the maximum input voltage rating for MC74VHC08DTRG-Q?
The MC74VHC08DTRG-Q supports DC input voltages from −0.5 V to +6.5 V, independent of VCC. This overvoltage tolerance allows safe interfacing with 5 V buses while the device operates from a 3.3 V supply, eliminating the need for external clamping diodes in mixed-voltage systems.
Does MC74VHC08DTRG-Q support TTL-level inputs?
No, MC74VHC08DTRG-Q uses standard CMOS input thresholds (VIH = 0.7×VCC, VIL = 0.3×VCC) and is not TTL-compatible. For TTL-level input support, consider the pin-compatible MC74VHCT08ADTR2G−Q, which accepts 2.0 V VIH and 0.8 V VIL at 5 V supply.
What is the thermal resistance (θJA) of MC74VHC08DTRG-Q in its TSSOP-14 package?
The MC74VHC08DTRG-Q in TSSOP-14 (Case 948G) has a junction-to-ambient thermal resistance (θJA) of 150 °C/W under JEDEC JESD51-7 conditions (76 mm × 114 mm, 2-oz copper, no airflow). This value assumes minimum pad spacing on FR4 and guides heatsinking decisions for continuous 8 mA output loading.
Is MC74VHC08DTRG-Q qualified for automotive applications?
Yes, MC74VHC08DTRG-Q is AEC-Q100 qualified (Grade 1: −40 °C to +125 °C ambient) and PPAP capable. The "−Q" suffix denotes automotive-specific site controls, change management, and traceability - required for production use in body control, lighting, and infotainment modules.
What is the quiescent supply current (ICC) specification for MC74VHC08DTRG-Q?
The MC74VHC08DTRG-Q has a maximum quiescent supply current (ICC) of 2.0 µA at TA = 25°C and VCC = 5.5 V, with all inputs tied to VCC or GND. This ultra-low static current supports energy-sensitive applications such as battery-backed monitoring circuits and always-on wake-up logic.
