Product details
Overview
74HC2G34GV-Q100 from Nexperia is an automotive-qualified dual non-inverting buffer gate in SC-74 (SOT457) package, operating from 2.0 V to 6.0 V supply, delivering balanced propagation delays as low as 8 ns at 6.0 V/50 pF, with CMOS-level inputs and AEC-Q100 Grade 1 qualification for under-hood control modules.
For engineers reviewing the 74HC2G34GV-Q100 datasheet, 74HC2G34GV-Q100 pinout, 74HC2G34GV-Q100 application, or 74HC2G34GV-Q100 equivalent, key selection criteria include input voltage compatibility (CMOS logic levels), guaranteed operation up to +125 °C ambient, output drive capability of ±4 mA at 4.5 V, and integrated input clamp diodes enabling safe interfacing to voltages exceeding VCC.
Technical Context
This device implements two independent, unidirectional CMOS buffer gates with rail-to-rail input tolerance enabled by internal clamp diodes - allowing external current-limiting resistors to safely interface signals above VCC. Each gate provides true non-inverting logic transfer (L→L, H→H) with no hysteresis or Schmitt-trigger behavior.
It operates across two distinct supply regimes: the 74HC variant supports 2.0–6.0 V with VIH/VIL scaling proportionally to VCC, while its pin-compatible 74HCT counterpart (not this part) uses fixed TTL-compatible thresholds (VIH = 2.0 V min, VIL = 0.8 V max) and is restricted to 4.5–5.5 V. Both share identical pinout, package, and thermal specifications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - enables direct integration into 3.3 V and 5 V automotive subsystems without level-shifting. |
| Propagation Delay (tpd) | 8 ns max at VCC = 6.0 V, CL = 50 pF - ensures timing-critical signal buffering in body control and sensor interface paths. |
| Output Drive Strength | ±4.0 mA at VCC = 4.5 V - sufficient to drive multiple 74HC inputs or moderate PCB trace capacitance without degradation. |
| Operating Temperature | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for engine bay and powertrain applications. |
| Input Clamp Diodes | Integrated - permits use of series resistors to interface 12 V wake-up signals or CAN transceiver sideband lines to VCC-referenced logic. |
| ESD Robustness | HBM > 2000 V, CDM > 1000 V - reduces susceptibility to assembly-line and field ESD events in automotive manufacturing. |
| Power Dissipation | 250 mW max at Tj ≤ 89 °C (SOT457) - supports compact placement near other thermally active components. |
Pinout & Package
SC-74 (SOT457) plastic surface-mounted package: 6-pin, 1.7 mm body width, 0.95 mm height, lead pitch 0.95 mm, pin 1 index located below marking code "P34" in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First buffer input - accepts CMOS-level signals; clamped to GND and VCC for overvoltage resilience. |
| 2 | GND | Dedicated ground reference - must be connected directly to low-impedance system ground plane to maintain noise immunity. |
| 3 | 2A | Second buffer input - electrically isolated from 1A; supports independent signal routing on same die. |
| 4 | 2Y | Second buffer output - provides rail-to-rail CMOS-compatible output swing with matched rise/fall times. |
| 5 | VCC | Positive supply - decoupling capacitor (100 nF ceramic) required within 5 mm for stable high-speed operation. |
| 6 | 1Y | First buffer output - phase-aligned with 1A; propagation delay matched to 2Y within 1 ns over temperature. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for continuous operation from −40 °C to +125 °C ambient - eliminates need for derating in engine control units. |
| Wide VCC range (2.0–6.0 V) | Supports single-bom deployment across 3.3 V infotainment domains and 5 V powertrain modules without redesign. |
| Balanced propagation delays | tpd mismatch between channels < 0.5 ns - critical for synchronized signal distribution in clock fanout or bus enable paths. |
| Unlimited input rise/fall times | No minimum edge rate requirement - compatible with slow-switching sensors (e.g., thermistors, potentiometers) and fast MCU outputs alike. |
| High noise immunity | Typical noise margin > 40 % of VCC - suppresses false triggering from coupled ignition or alternator ripple in 12 V systems. |
Applications
| Body Control Module (BCM) | Instrument Cluster Interface |
|---|---|
|
Use Scenario: Isolating and strengthening LIN bus wake-up signals routed from door modules to central BCM microcontroller. IC Role / Device Role / Timing Role: Dual buffer amplifies weak pull-up signals while preserving edge integrity and blocking reverse current flow. Use Value: Enables reliable multi-node wake detection without adding discrete transistors or increasing PCB layer count. |
Use Scenario: Level-shifting and driving analog gauge driver IC inputs from a 3.3 V MCU in digital instrument clusters. IC Role / Device Role / Timing Role: Buffer isolates MCU GPIO from capacitive load of gauge driver inputs and prevents voltage droop during simultaneous updates. Use Value: Eliminates flicker or lag in stepper motor-driven speedometer needles during rapid acceleration/deceleration events. |
| Engine Control Unit (ECU) Sensor Conditioning | ADAS Camera Power Sequencing |
|
Use Scenario: Conditioning throttle position sensor (TPS) analog wiper signals before ADC sampling in high-noise engine compartments. IC Role / Device Role / Timing Role: Buffer provides high-impedance input to prevent loading of resistive TPS element and low-impedance output to drive ADC sample-and-hold. Use Value: Maintains <0.1 % linearity error across full temperature range despite ECU board self-heating. |
Use Scenario: Synchronizing power-on reset sequencing between image sensor, ISP, and serializer in rear-view camera modules. IC Role / Device Role / Timing Role: Dual buffer distributes clean, delayed enable signals to three independent LDOs with matched propagation delay. Use Value: Guarantees strict <100 ns skew between power rails to prevent sensor initialization faults during cold start. |
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 | TTL-compatible inputs (VIH = 2.0 V min), narrower VCC range (4.5–5.5 V), identical pinout and package. | Required where legacy 5 V microcontrollers with TTL outputs drive the buffer without level shifters. | Select when interfacing to older 5 V MCUs or FPGAs with non-CMOS output drivers. |
| SN74LVC2G34DBVR | Lower VCC range (1.65–5.5 V), higher drive (±24 mA), no AEC-Q100 qualification, same SOT-23-6 footprint. | Suitable for non-automotive industrial or consumer designs requiring higher current or lower voltage operation. | Choose only for non-automotive applications needing stronger drive or sub-2.0 V compatibility. |

FAQ
Is 74HC2G34GV-Q100 pin-compatible with 74HCT2G34GV-Q100?
Yes - both share identical SC-74 (SOT457) package, pin assignment, and mechanical dimensions. The only functional difference is input threshold logic: 74HC2G34GV-Q100 uses CMOS-level inputs (VIH ≈ 0.7×VCC), while 74HCT2G34GV-Q100 uses fixed TTL thresholds (VIH = 2.0 V min). No PCB redesign is needed for substitution.
Can this buffer drive a 50 pF load at 10 MHz without signal degradation?
Yes - with tpd = 8 ns (max) and tt = 5 ns (max) at VCC = 6.0 V/CL = 50 pF, the device supports data rates up to ~25 Mbps (NRZ) with <10 % duty-cycle distortion. Its CPD = 10 pF ensures dynamic power remains below 360 μW at 10 MHz, minimizing self-heating in dense layouts.
What is the maximum allowable voltage on input pins when VCC = 0 V?
Per absolute maximum ratings, input voltage may range from −0.5 V to VCC + 0.5 V. With VCC = 0 V, inputs must stay within −0.5 V to +0.5 V. However, the integrated clamp diodes allow safe biasing up to −0.5 V or VCC + 0.5 V only if input current is limited to ±20 mA - external resistors are mandatory for off-state overvoltage protection.
Does this part support hot-swap or live-insertion in powered systems?
No - it lacks Ioff (power-off protection) or IOZ (three-state during power-down) features. When VCC is unpowered, inputs and outputs become undefined, and applying signals risks latch-up or excessive current through internal diodes. Always power VCC before applying input signals in hot-swap scenarios.
