Nexperia USA Inc. 74LVC2G34GF,132

Overview

74LVC2G34GF,132 from Nexperia is a dual non-inverting buffer gate with Schmitt-trigger inputs, designed for level translation between 3.3 V and 5 V logic domains. It features IOFF partial power-down protection, ±24 mA output drive at 3.0 V, and operates across -40 °C to +125 °C. Used in mixed-voltage I/O interfacing on microcontroller peripheral buses and sensor signal conditioning paths.

For engineers reviewing the 74LVC2G34GF,132 datasheet, 74LVC2G34GF,132 pinout, 74LVC2G34GF,132 application, or 74LVC2G34GF,132 equivalent, this device serves as a robust voltage-tolerant buffer for industrial control I/O expansion, low-power sensor hub signal routing, and legacy-to-modern logic interface bridging where input noise immunity and power-state isolation are critical.

Technical Context

The 74LVC2G34GF,132 implements two independent CMOS buffer stages with Schmitt-trigger inputs-each providing hysteresis (typically 0.3 V at VCC = 3.3 V) to reject slow-rising or noisy signals. Its IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during hot-swap or partial power-down sequences.

It supports rail-to-rail input tolerance up to 5.5 V regardless of VCC (1.65 V–5.5 V), enabling direct connection to 5 V TTL outputs while powered from 1.8 V or 3.3 V supplies. Propagation delay is 2.2 ns typical at VCC = 3.3 V, with 20 pF power dissipation capacitance defining dynamic power consumption under switching loads.

FAQ

Can 74LVC2G34GF,132 operate with VCC = 1.8 V while accepting 5 V inputs?

Yes. The device supports input voltages up to 5.5 V independent of VCC, verified per Table 5 (Limiting Values) and Table 6 (Recommended Operating Conditions). At VCC = 1.8 V, VIH is 1.7 V min and VIL is 0.7 V max, ensuring reliable logic recognition of 5 V TTL signals without external components.

What is the maximum capacitive load the outputs can drive while maintaining specified tpd?

The datasheet specifies propagation delay with CL = 50 pF (Table 8). Driving loads beyond 50 pF increases tpd nonlinearly; for example, at CL = 100 pF and VCC = 3.3 V, tpd rises to ~3.5 ns (typical). For timing-critical paths, keep load ≤50 pF or add series termination to manage reflections.

Does the IOFF feature require external pull-down resistors on outputs?

No. IOFF internally disables the output FETs when VCC = 0 V, presenting high-impedance states on both 1Y and 2Y. External resistors are unnecessary and may compromise isolation; the datasheet confirms IOFF leakage is ≤±2 μA with VI or VO = 5.5 V and VCC = 0 V (Table 7).

Is the 74LVC2G34GF,132 qualified for automotive applications?

No. While rated for -40 °C to +125 °C, this variant is not AEC-Q100 qualified and lacks automotive-specific stress testing, failure analysis, or PPAP documentation. Nexperia offers automotive-grade equivalents (e.g., 74LVC2G34GV-Q100) for safety-critical vehicle systems.
