Nexperia USA Inc. 74LVC1G125GW-Q100,

Overview

74LVC1G125GW-Q100 from Nexperia is a single-channel 3-state bus buffer/line driver qualified to AEC-Q100 Grade 1 for automotive use, operating from 1.65 V to 5.5 V supply, with ±24 mA output drive at 3.0 V, overvoltage-tolerant inputs up to 5.5 V, and IOFF partial power-down protection. It enables level translation between 3.3 V and 5 V domains in engine control units and ADAS sensor interfaces.

For engineers reviewing the 74LVC1G125GW-Q100 datasheet, 74LVC1G125GW-Q100 pinout, 74LVC1G125GW-Q100 application, or 74LVC1G125GW-Q100 equivalent, this page delivers verified functional behavior, automotive-grade thermal and ESD specs, TSSOP5 package layout, and direct substitution guidance for mixed-voltage signal routing in safety-critical vehicle subsystems.

Technical Context

This device implements a non-inverting buffer with active-low 3-state enable (OE), supporting bidirectional voltage translation via Schmitt-trigger inputs tolerant of slow edge rates. Its IOFF circuit actively disables outputs during power-down to block backflow current, meeting automotive partial-power-down requirements.

It operates across -40 °C to +125 °C with static input thresholds scaling with VCC (e.g., VIH = 0.7 × VCC at 4.5–5.5 V), and delivers propagation delays as low as 0.5 ns at 5 V while maintaining <4 μA ICC at 3.3 V - enabling low-power, high-speed signal conditioning in CAN/LIN interface buffers and sensor data acquisition paths.

FAQ

Can the 74LVC1G125GW-Q100 operate with a 1.65 V supply while accepting 5 V inputs?

Yes. The device supports 1.65 V to 5.5 V VCC and has overvoltage-tolerant inputs rated to 5.5 V regardless of supply voltage. At 1.65 V VCC, VIH is 0.65 × VCC (≈1.07 V) and VIL is 0.35 × VCC (≈0.58 V), allowing reliable detection of 5 V TTL-level signals without damage or logic misinterpretation.

What is the maximum capacitive load the output can drive while maintaining specified timing?

The datasheet specifies dynamic characteristics with 30–50 pF loads depending on VCC. At VCC = 3.3 V, the device drives up to 50 pF with tpd ≤ 4.5 ns and tdis ≤ 6 ns. Driving >50 pF increases propagation delay nonlinearly and may violate setup/hold margins in high-speed interfaces like SPI clock lines.

Does the IOFF feature require external biasing or configuration?

No. IOFF is fully automatic and requires no external components or configuration. When VCC drops to 0 V, internal circuitry forces the output into high-impedance state and limits leakage to ±2 μA, even if A or Y pins are held at 5.5 V - satisfying ISO 16750-2 power-off surge immunity requirements.

How does the Schmitt-trigger input improve noise immunity compared to standard CMOS inputs?

Schmitt-trigger inputs provide hysteresis (≥0.3 V at 3.3 V), meaning VIH and VIL differ by a fixed voltage margin. This prevents multiple transitions on slow-rising or noisy signals - such as those from hall-effect sensors or long harnesses - eliminating false triggering without adding external RC filters or debouncing firmware.
