Nexperia USA Inc. 74HC2G34GW-Q100H

Overview

74HC2G34GW-Q100 from Nexperia is an automotive-qualified dual non-inverting buffer gate in TSSOP6 (SOT363-2) 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 input compatibility and AEC-Q100 Grade 1 qualification for under-hood automotive signal conditioning.

For engineers reviewing the 74HC2G34GW-Q100 datasheet, 74HC2G34GW-Q100 pinout, 74HC2G34GW-Q100 application, or 74HC2G34GW-Q100 equivalent, key selection criteria include its wide VCC range (2.0–6.0 V), guaranteed operation up to +125 °C, input clamp diodes enabling overvoltage-tolerant interfacing, and dual independent buffer architecture supporting isolated signal routing in safety-critical automotive subsystems.

Technical Context

This device implements two independent, unidirectional CMOS buffer gates with no internal feedback or latching-each channel passes logic state directly from input (1A/2A) to output (1Y/2Y) with no inversion. Inputs feature integrated clamp diodes to GND and VCC, permitting safe interface to signals exceeding VCC when used with current-limiting resistors.

It operates across two distinct voltage domains: full 2.0–6.0 V compliance for HC logic levels, and dedicated 4.5–5.5 V support for HCT-compatible TTL-level inputs. Propagation delay and transition time are characterized across -40 °C to +125 °C, with derated power dissipation above 83 °C for the TSSOP6 package.

FAQ

What is the maximum allowable supply voltage for continuous operation?

The absolute maximum VCC is +7.0 V per IEC 60134 limiting values, but recommended continuous operation is capped at 6.0 V. Exceeding 6.0 V risks accelerated parametric drift and reduced lifetime, especially above 83 °C where power derating applies. Operation at 6.0 V is fully characterized for timing, drive, and noise immunity across -40 °C to +125 °C.

Can this device interface a 12 V sensor signal to a 5 V MCU input?

Yes-its integrated input clamp diodes allow safe interface to signals up to VCC + 0.5 V, provided a series current-limiting resistor is used. For a 12 V sensor, a 2.2 kΩ resistor limits peak clamp current to ~10 mA when VCC = 5 V, staying within the ±20 mA IIK rating. This avoids external protection components while maintaining logic-level compatibility.

Is there any functional difference between the GW and GV package variants?

No functional difference exists-the 74HC2G34GW-Q100 (SOT363-2/TSSOP6) and 74HC2G34GV-Q100 (SOT457/SC-74) share identical electrical specifications, thermal limits, and AEC-Q100 qualification. The distinction is purely mechanical: GW uses a 1.25 mm body width TSSOP6; GV uses a wider 3.1 mm SC-74 package with different land pattern and thermal resistance (4.1 mW/K derating above 89 °C).

Does this buffer support Schmitt-trigger inputs for noisy automotive environments?

No-this device uses standard CMOS inputs without hysteresis. Its high noise immunity stems from rail-to-rail VIH/VIL thresholds (e.g., VIH = 3.15 V min at VCC = 4.5 V) and low input capacitance (1.5 pF), not Schmitt triggering. For inherently noisy signals like switch debouncing or inductive load feedback, an external RC filter or dedicated Schmitt-trigger buffer (e.g., 74HC14) is required upstream.
