Product details
Overview
74HCT2G34GW-Q100 from Nexperia is an automotive-qualified dual non-inverting buffer gate in TSSOP6 (SOT363-2) package, operating from 4.5 V to 5.5 V supply, delivering TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max), 10 ns typical propagation delay at 4.5 V/50 pF, and ±4 mA output drive-used for signal level translation and fanout expansion in engine control units and body electronics.
For engineers reviewing the 74HCT2G34GW-Q100 datasheet, 74HCT2G34GW-Q100 pinout, 74HCT2G34GW-Q100 application, or 74HCT2G34GW-Q100 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification (-40 °C to +125 °C), TTL-level input compatibility, low dynamic power (CPD = 9 pF), and dual-buffer isolation in space-constrained automotive PCBs.
Technical Context
This device implements two independent CMOS-based non-inverting buffers with TTL-compatible input thresholds, enabling direct interfacing with legacy 5 V TTL logic while maintaining low static current (ICC ≤ 20 μA at +125 °C). Each channel features clamp diodes on inputs, allowing safe interface to voltages exceeding VCC when used with current-limiting resistors.
Propagation delay is tightly balanced between channels (tpd ≤ 29 ns max over full temperature range), and transition times are symmetrical (tt ≤ 25 ns max), supporting clean digital signal integrity in timing-critical automotive subsystems such as sensor signal conditioning and microcontroller I/O expansion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures stable operation across automotive battery rail variations including cold-crank transients. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - Guarantees reliable recognition of standard 5 V TTL logic levels without level-shifting circuitry. |
| Propagation Delay | 10 ns typ / 29 ns max (VCC = 4.5 V, CL = 50 pF) - Supports >10 MHz signal routing in real-time control loops. |
| Output Drive | ±4.0 mA - Sufficient to drive multiple 74-series inputs or small capacitive loads (<30 pF) without external buffering. |
| Operating Temperature | -40 °C to +125 °C - Qualified per AEC-Q100 Grade 1 for under-hood and transmission-control module deployment. |
| Power Dissipation Cap | 250 mW (TSSOP6) - Enables use in thermally constrained modules without forced cooling or derating below 83 °C. |
| ESD Robustness | HBM > 2000 V, CDM > 1000 V - Reduces risk of field failure during handling and assembly in automotive manufacturing lines. |
Pinout & Package
TSSOP6 (SOT363-2) plastic thin shrink small outline package, 6-pin, 1.25 mm body width, 0.65 mm lead pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First buffer input - Accepts TTL-level signals; internally clamped to prevent overvoltage damage. |
| 2 | GND | Digital ground reference - Must be connected to system ground plane for noise immunity and correct logic thresholds. |
| 3 | 2A | Second buffer input - Electrically isolated from 1A; enables independent signal routing paths. |
| 4 | 2Y | Second buffer output - Provides inverted-isolation-free output with rail-to-rail swing and ±4 mA sourcing/sinking. |
| 5 | VCC | Positive supply - Decoupling capacitor (100 nF) required within 5 mm for stable high-speed switching. |
| 6 | 1Y | First buffer output - Matches 2Y electrically; allows matched trace length routing for skew-sensitive applications. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including thermal cycling and humidity testing. |
| TTL-compatible inputs | Accepts standard 5 V TTL logic levels without external biasing, simplifying integration with legacy MCU peripherals. |
| Input clamp diodes | Enable safe interface to voltages up to VCC + 0.5 V using series current-limiting resistors (e.g., 1 kΩ). |
| Balanced propagation delays | Channel-to-channel tpd mismatch ≤ 2 ns ensures deterministic timing in dual-signal paths like clock/data pairs. |
| Low dynamic power | CPD = 9 pF enables <10 μW/MHz dynamic power at 5 V, critical for always-on vehicle network nodes. |
Applications
| Engine Control Unit (ECU) | Body Control Module (BCM) |
|---|---|
|
Use Scenario: Isolating crankshaft position sensor signals before feeding into a 32-bit MCU's capture timer input. IC Role / Device Role / Timing Role: Dual buffer provides noise-immune signal conditioning and fanout to both main CPU and redundant safety monitor. Use Value: Clamp diodes protect against inductive kickback; matched delays ensure synchronized edge detection across dual paths. |
Use Scenario: Level-translating door lock actuator enable signals from a 3.3 V microcontroller to 5 V solenoid drivers. IC Role / Device Role / Timing Role: Non-inverting buffer translates logic levels while preserving timing integrity for pulse-width modulated lock/unlock commands. Use Value: TTL input compatibility eliminates need for discrete resistor networks; ±4 mA drive directly interfaces with gate drivers. |
| Instrument Cluster Display | Transmission Control Unit (TCU) |
|
Use Scenario: Driving multiplexed LED backlight segments from a low-power display controller with limited I/O drive strength. IC Role / Device Role / Timing Role: Dual buffer expands GPIO count and strengthens signal edges to reduce EMI in high-density display PCBs. Use Value: Low CPD (9 pF) minimizes switching noise; 125 °C rating supports placement near heat-generating display drivers. |
Use Scenario: Buffering CAN transceiver standby control and wake-up interrupt signals in a dual-CAN architecture. IC Role / Device Role / Timing Role: Signal isolation prevents cross-talk between high-noise CAN PHY and low-voltage MCU interrupt lines. Use Value: AEC-Q100 qualification ensures reliability across vibration, thermal shock, and ESD events in transmission environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT2G34GV-Q100 | Same electrical specs; SC-74 (SOT457) package with 1.7 mm body width and 0.95 mm lead pitch. | Higher thermal resistance (4.1 mW/K derating above 89 °C vs. 3.7 mW/K at 83 °C for TSSOP6). | Select for legacy board layouts requiring SC-74 footprint or higher mechanical robustness in high-vibration zones. |
| SN74LVC2G34QDCURQ1 | Lower VCC range (1.65–5.5 V); CMOS inputs (VIH = 70% VCC); 32 mA output drive; different pinout (1A/1Y/GND/2Y/VCC/2A). | Not pin-compatible; requires PCB redesign; supports wider voltage scaling but lacks TTL input compatibility. | Choose only if migrating to 3.3 V systems or requiring higher drive strength; not a drop-in replacement. |
Compared with 74HCT2G34GW-Q100, the GV variant offers identical functionality in a physically larger package with slightly worse thermal performance, while the TI part trades TTL compatibility and pinout for broader supply flexibility and higher drive-making it unsuitable for direct substitution in existing AEC-Q100-compliant designs.

FAQ
What is the maximum allowable input voltage beyond VCC for 74HCT2G34GW-Q100?
The device includes input clamp diodes that permit safe operation with input voltages up to VCC + 0.5 V, provided external current-limiting resistors restrict IIK to ±20 mA. Exceeding this limit risks permanent damage per Absolute Maximum Ratings (Table 5).
Can 74HCT2G34GW-Q100 operate reliably at 3.3 V supply?
No. The 74HCT variant is specified only for 4.5 V to 5.5 V operation. At 3.3 V, input thresholds (VIH/VIL) become undefined and output drive falls outside guaranteed limits. Use 74LVC2G34 or 74AHC2G34 for 3.3 V systems.
Is the TSSOP6 (SOT363-2) package lead-free and RoHS compliant?
Yes. Nexperia confirms the 74HCT2G34GW-Q100 uses 100% matte tin lead finish and complies with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with no exemptions applied.
How does the device behave when one input is driven while the other is left floating?
Unused inputs must be tied to VCC or GND. Floating inputs cause increased ICC, unpredictable output states, and potential oscillation due to CMOS input stage metastability-violating recommended operating conditions and risking EMC failures in automotive validation.
