Product details
Overview
74HC3G34DP-Q100 from Nexperia is an automotive-qualified triple non-inverting buffer gate in TSSOP8 (SOT505-2) package, operating from 2.0 V to 6.0 V supply, with CMOS-level inputs, -40 °C to +125 °C temperature range, and AEC-Q100 Grade 1 qualification. It provides three independent buffered outputs for signal conditioning in automotive body control modules, infotainment power sequencing, and sensor interface signal routing.
For engineers reviewing the 74HC3G34DP-Q100 datasheet, 74HC3G34DP-Q100 pinout, 74HC3G34DP-Q100 application, or 74HC3G34DP-Q100 equivalent, key selection criteria include input voltage compatibility (CMOS), propagation delay at 4.5 V (9–19 ns), output drive strength (±4.0 mA), thermal derating behavior above 96 °C, and TSSOP8 mechanical footprint compliance.
Technical Context
This device implements three independent single-bit non-inverting buffers with clamp diodes on all inputs, enabling safe interfacing to voltages exceeding VCC via external current-limiting resistors. Each buffer features symmetrical input/output logic thresholds defined per VCC (e.g., VIH = 3.15 V min at VCC = 4.5 V).
It operates under JEDEC JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V) standards, supports dynamic power calculation via CPD = 10 pF, and maintains latch-up immunity >100 mA per JESD78 Class II Level B across its full automotive temperature range.
Key Specifications

IC Role / Device Role / Timing Role: Signal-level translator and current-isolation buffer between 12 V sensor circuitry and 3.3 V MCU inputs. Use Value: Prevents backfeed into MCU during deep sleep; enables use of simple resistor-based voltage translation instead of active level shifters. | Use Scenario: Enabling controlled power-up sequence of display backlight, audio amplifier, and USB controller ICs after ignition-on detection. IC Role / Device Role / Timing Role: Glue logic buffer providing clean, delayed enable signals with defined rise/fall times. Use Value: Ensures strict power-up ordering without software intervention; eliminates race conditions during cold start. |

IC Role / Device Role / Timing Role: Low-skew, low-jitter buffer replicating a single clock-enable line to multiple downstream receivers. Use Value: Reduces inter-channel skew to <2 ns (typ), preserving pixel alignment across multi-lane camera interfaces. | Use Scenario: Driving segment enable lines for segmented LCD or OLED driver ICs in analog gauge clusters. IC Role / Device Role / Timing Role: Logic-level repeater isolating microcontroller GPIOs from capacitive display bus loading. Use Value: Maintains fast edge rates (>5 V/ns) despite 200 pF bus capacitance, preventing ghosting or flicker. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triple buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT3G34DP-Q100 | TTL-compatible inputs (VIH = 2.0 V min), identical pinout and package | Better interoperability with legacy 5 V TTL logic; slightly higher ICC at VCC = 4.5 V | Select when interfacing with older microcontrollers or discrete transistor logic families. |
| SN74LVC3G34DCUR | 3.3 V only (1.65–3.6 V), smaller VSSOP8 (SOT765-1), no AEC-Q100 qualification | Lower power and size for non-automotive portable devices; not suitable for under-hood use | Choose only for consumer or industrial applications where automotive qualification is unnecessary. |
Compared with 74HC3G34DP-Q100, the 74HCT3G34DP-Q100 offers easier integration with 5 V legacy systems but sacrifices some noise margin, while the SN74LVC3G34DCUR reduces board area and static power at the cost of temperature range and automotive compliance.

FAQ
What is the maximum allowable input voltage when VCC = 3.3 V?
The device includes input clamp diodes to VCC and GND. With VCC = 3.3 V, inputs may safely exceed VCC up to 7.0 V absolute maximum (per Table 5), provided external current-limiting resistors restrict IIK to ≤±20 mA. For example, a 10 kΩ resistor limits current to <400 μA at 7 V, well within rating.
Can 74HC3G34DP-Q100 drive a 50 pF load at 10 MHz without signal degradation?
Yes. At VCC = 4.5 V, typical propagation delay is 9 ns and transition time is 6 ns. With CPD = 10 pF, dynamic power at 10 MHz is ~2.0 mW per switching input - well within the 250 mW total package limit. Output rise/fall times remain <10 ns, preserving signal fidelity into 50 pF.
Is pin 1 orientation consistent between SOT505-2 and SOT765-1 packages?
Yes. Both TSSOP8 (SOT505-2) and VSSOP8 (SOT765-1) packages use identical pin 1 indexing: pin 1 is located in the lower-left corner of the device body, below the marking code (H34 for this part), with pins numbered counter-clockwise. Mechanical drawings in Figures 5 and 6 confirm identical pin 1 location and numbering convention.
Does the device require external pull-up or pull-down resistors on unused inputs?
No. Unused inputs must be tied to VCC or GND - not left floating - to prevent increased ICC and potential oscillation. The internal structure does not include weak pull-ups/pull-downs; therefore, external DC termination is mandatory for any unconnected 1A/2A/3A pins to ensure predictable logic states and minimize power consumption.
