Product details
Overview
74HCT2G34GV-Q100 from Nexperia is an automotive-qualified dual non-inverting buffer gate in SC-74 (SOT457) 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 74HCT2G34GV-Q100 datasheet, 74HCT2G34GV-Q100 pinout, 74HCT2G34GV-Q100 application, or 74HCT2G34GV-Q100 equivalent, this page delivers verified functional identity, automotive-grade thermal and ESD specs (-40 °C to +125 °C, HBM >2000 V), pin-accurate terminal roles, and real-world substitution guidance for AEC-Q100-compliant designs.
Technical Context
This device implements two independent CMOS-based non-inverting buffers with TTL-level input compatibility, enabling direct interfacing with legacy 5 V logic while maintaining low static current (ICC ≤ 20 μA at +125 °C). Each channel features clamped inputs supporting external current-limiting resistors for overvoltage tolerance beyond VCC.
Propagation delays are balanced across channels (tpd ≤ 29 ns max at -40 °C to +125 °C, VCC = 4.5 V, CL = 50 pF), and output transition times (tt ≤ 25 ns) ensure clean edge integrity in noise-sensitive automotive subsystems such as sensor signal conditioning and microcontroller I/O buffering.
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 TTL logic levels without level-shifting circuitry. |
| Propagation Delay | 10 ns typ / 29 ns max (VCC = 4.5 V, CL = 50 pF, -40 °C to +125 °C) - Supports timing-critical signal routing in real-time control loops. |
| Output Drive | ±4.0 mA (VOH/VOL @ VCC = 4.5 V) - Sufficient to drive multiple 74-series inputs or small capacitive loads (<30 pF) directly. |
| ESD Robustness | HBM >2000 V, CDM >1000 V - Meets AEC-Q100 stress requirements for assembly and field reliability in harsh environments. |
| Operating Temperature | -40 °C to +125 °C - Qualified for under-hood and transmission-control module placement per Grade 1 AEC-Q100. |
| Power Dissipation | CPD = 9 pF - Enables accurate dynamic power estimation (PD = CPD × VCC² × fi × N) for thermal budgeting in dense PCB layouts. |
Pinout & Package
SC-74 (SOT457) plastic surface-mounted package: 6-pin, 1.7 mm body width, 0.65 mm pitch, pin 1 indicator located below marking code (U34) on lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Channel 1 input | Accepts TTL-level signals; internally clamped to support overvoltage resilience with series resistor. |
| GND | Ground reference | Common return path for both channels; must be low-impedance to minimize ground bounce in switching operation. |
| 2A | Channel 2 input | Independent input with identical electrical characteristics to 1A; enables dual-signal buffering without crosstalk. |
| 2Y | Channel 2 output | Non-inverted replica of 2A; capable of sourcing/sinking ±4 mA into defined load conditions. |
| VCC | Supply voltage | Primary power rail; decoupling capacitor (100 nF) recommended within 5 mm for noise suppression. |
| 1Y | Channel 1 output | Non-inverted replica of 1A; electrically isolated from 2Y to prevent inter-channel loading effects. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including temperature cycling and humidity testing. |
| TTL-compatible inputs | VIH/VIL thresholds match legacy 5 V TTL families, eliminating need for external level translators in mixed-logic systems. |
| Input clamp diodes | Enable safe interface to voltages up to VCC + 0.5 V using current-limiting resistors-critical for sensor signal conditioning with transient overvoltage. |
| Balanced propagation delays | tpd matching between channels <1 ns typical ensures deterministic timing in dual-path signal distribution (e.g., clock/data pairs). |
| Low quiescent current | ICC ≤ 20 μA at +125 °C reduces system standby power-key for always-on vehicle networks like LIN or CAN partial networking. |
Applications
| Engine Control Unit (ECU) | Body Control Module (BCM) |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT2G34GW-Q100 | TSSOP6 (SOT363-2) package: 1.25 mm body width, 0.65 mm pitch, different land pattern and thermal resistance. | Preferred for higher-density layouts where footprint area is constrained; slightly better thermal performance at full load. | Select when board space optimization or automated optical inspection (AOI) compatibility with TSSOP is required. |
| SN74LVC2G34QDCURQ1 | Wider supply range (1.65–5.5 V), lower ICC (≤10 μA), but only AEC-Q100 Grade 2 (–40 °C to +105 °C). | Suitable for cabin modules with less extreme thermal demands; not rated for under-hood deployment. | Choose for cost-sensitive interior applications where extended temperature range is unnecessary. |
Compared with 74HCT2G34GV-Q100, the GW variant offers identical logic and electrical behavior in a smaller-footprint TSSOP package, while the TI part trades Grade 1 qualification for broader voltage flexibility and lower static power-making each suitable for distinct automotive subsystems.

FAQ
Is 74HCT2G34GV-Q100 pin-compatible with 74HC2G34GV-Q100?
Yes-both share identical SC-74 (SOT457) pinout and mechanical footprint. However, 74HC2G34GV-Q100 uses CMOS-level inputs (VIH ≥ 3.15 V at VCC = 4.5 V), whereas 74HCT2G34GV-Q100 accepts TTL-level inputs (VIH ≥ 2.0 V), making them electrically incompatible without redesign of upstream drivers.
What is the maximum capacitive load this buffer can drive reliably?
At VCC = 4.5 V and Tamb = +125 °C, the device maintains specified VOL ≤ 0.4 V and tpd ≤ 29 ns driving up to 50 pF (per datasheet test condition). For loads exceeding 50 pF, propagation delay increases linearly; derating is required above 75 pF to maintain timing margin in synchronous systems.
Does this part support hot insertion or live bus operation?
No-74HCT2G34GV-Q100 lacks Ioff protection or power-off isolation. Applying input signals while VCC = 0 V may forward-bias internal clamp diodes, causing excessive current flow. Power sequencing must ensure VCC is stable before asserting inputs.
Can this buffer be used to drive a 50 Ω transmission line?
Not directly-the output stage is designed for CMOS/TTL fanout (±4 mA), not 50 Ω line termination. Driving such a line would require external series termination (e.g., 33 Ω resistor) and careful impedance matching; signal integrity validation via TDR is recommended for lengths >5 cm at >10 MHz.
