Nexperia USA Inc. 74LVC2G241DC,125

Overview

74LVC2G241DC,125 from Nexperia is a dual non-inverting 3-state buffer/line driver in VSSOP8 (SOT765-1) package, operating from 1.65 V to 5.5 V supply, with ±24 mA output drive at 3.0 V, Schmitt-trigger inputs for noise immunity, and 5 V-tolerant I/O enabling mixed-voltage level translation in industrial bus interfaces.

For engineers reviewing the 74LVC2G241DC,125 datasheet, 74LVC2G241DC,125 pinout, 74LVC2G241DC,125 application, or 74LVC2G241DC,125 equivalent, this device serves as a compact, low-power bidirectional signal conditioner for FPGA I/O expansion, microcontroller peripheral buffering, and legacy 5 V–3.3 V interface bridging where space-constrained PCBs require high noise immunity and IOFF power-down protection.

Technical Context

This device implements two independent non-inverting buffers, each with separate 3-state control: 1OE (active LOW) and 2OE (active HIGH), enabling asymmetric enable logic in system-level signal routing. Its Schmitt-trigger inputs accept slow-rising signals down to 10 ns/V transition rate and tolerate input voltages up to 5.5 V regardless of VCC.

The IOFF circuit ensures outputs enter high-impedance state during partial power-down, blocking backflow current when VCC = 0 V. Input leakage remains ≤±1 μA across -40 °C to +125 °C, and propagation delay ranges from 0.5 ns (VCC = 5.5 V) to 11.0 ns (VCC = 1.65 V) per buffer path.

FAQ

Can the 74LVC2G241DC,125 operate with VCC = 1.65 V while driving 5 V inputs?

Yes - all inputs are 5 V tolerant regardless of VCC level, including at the minimum 1.65 V supply. The device correctly interprets 0 V–5.5 V input signals and produces valid CMOS output levels referenced to VCC, enabling true level translation without external components.

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

The datasheet specifies timing with 30–50 pF load capacitance depending on VCC. At VCC = 3.3 V and CL = 50 pF, tpd remains ≤4.7 ns. Driving >50 pF increases propagation delay nonlinearly and may violate setup/hold margins in high-speed interfaces - external series termination or buffer staging is recommended beyond 75 pF.

Does the IOFF feature protect against backfeed when only one supply rail is active?

Yes - IOFF activates automatically when VCC = 0 V, disabling both outputs and limiting OFF-state current to ≤±2 μA even if 5 V is applied to inputs or outputs. This prevents current flow into a powered-down section, satisfying IEC 61000-4-2 and IPC-9592 requirements for partial power-down safety.

How does the Schmitt-trigger input improve reliability in noisy factory environments?

Schmitt-trigger inputs provide ≥0.3 V hysteresis at 3.3 V, rejecting noise spikes <300 mV and allowing clean logic transitions even with slow-rising signals (≥10 ns/V). This eliminates false triggering on long cables or near AC motor drives without adding external RC filters or software debouncing.
