Nexperia USA Inc. 74LVC1G125GM,115

Overview

74LVC1G125GM,115 from Nexperia is a single 3-state bus buffer/line driver with Schmitt-trigger inputs, IOFF partial power-down support, and 1.65 V to 5.5 V supply operation. It enables level translation between 3.3 V and 5 V logic domains, provides ±24 mA output drive at 3.0 V, and operates across –40 °C to +125 °C for industrial interface isolation in microcontroller I/O expansion circuits.

For engineers reviewing the 74LVC1G125GM,115 datasheet, 74LVC1G125GM,115 pinout, 74LVC1G125GM,115 application, or 74LVC1G125GM,115 equivalent, this device serves as a compact, low-power, voltage-tolerant unidirectional buffer for mixed-voltage signal routing, I²C/SPI bus buffering, and GPIO extension where space-constrained XSON6 packaging and robust power-down behavior are required.

Technical Context

The 74LVC1G125GM,115 implements a single non-inverting buffer with active-low 3-state enable (OE), supporting bidirectional voltage translation via overvoltage-tolerant inputs rated to 5.5 V while powered from as low as 1.65 V. Its Schmitt-trigger input thresholds improve noise immunity against slow-rising signals in noisy industrial environments.

IOFF circuitry actively disables the output stage when VCC = 0 V, blocking backflow current and enabling hot-insertion capability in partial-power-down systems. Propagation delay ranges from 0.5 ns (VCC = 5.5 V) to 10.5 ns (VCC = 1.65 V, –40 °C to +85 °C), ensuring timing predictability across supply and temperature extremes.

FAQ

Can the 74LVC1G125GM,115 safely interface a 5 V microcontroller output with a 1.8 V FPGA input?

Yes - its inputs tolerate up to 5.5 V regardless of VCC voltage, and its output VOH/VOL levels meet 1.8 V logic thresholds when VCC = 1.8 V (VIH = 0.65 × VCC = 1.17 V, VIL = 0.35 × VCC = 0.63 V). No external resistors or level shifters are needed.

Does the IOFF feature activate automatically when VCC drops below a threshold?

IOFF activates only when VCC = 0 V, not at low voltage thresholds. The circuit monitors VCC directly and disables the output stage only when supply is fully removed, preventing backflow current during complete power loss - not brown-out conditions.

What is the maximum capacitive load the 74LVC1G125GM,115 can drive at 3.3 V while maintaining 4 ns propagation delay?

At VCC = 3.3 V and Tamb = 25 °C, the device drives 30 pF loads with tPD ≤ 4 ns (typical 2.1 ns). For guaranteed 4 ns max across –40 °C to +125 °C, load capacitance must be ≤ 25 pF per the dynamic characteristics table.

Is the n.c. pin on the SOT886 package required to be grounded for thermal or EMI performance?

No - the n.c. pin has no internal connection and serves only as a mechanical anchor. It may be left floating or connected to GND for improved mechanical rigidity; neither choice affects thermal dissipation or EMI behavior, as confirmed in Nexperia's SOT886 layout guidelines.
