Nexperia USA Inc. 74LVC1G17GW-Q100,1

Overview

74LVC1G17GW-Q100 from Nexperia is a single-channel Schmitt-trigger buffer IC qualified to AEC-Q100 Grade 1 for automotive use, operating from −40 °C to +125 °C with supply voltage range 1.65 V to 5.5 V, ±24 mA output drive at 3.0 V, and IOFF partial power-down protection. It interfaces mixed-voltage logic (3.3 V/5 V) in body control modules and sensor signal conditioning.

Technical Context

This device implements a single non-inverting Schmitt-trigger buffer with hysteresis (VH = 0.47–0.88 V depending on VCC), enabling robust noise rejection on slow or noisy digital inputs such as switch debouncing or analog sensor outputs. Its IOFF circuit actively disables the output when VCC = 0 V, preventing backflow current during partial power-down sequences in automotive domain controllers.

The input is overvoltage tolerant to 5.5 V regardless of VCC level (1.65–5.5 V), allowing direct interfacing with 5 V legacy signals into 3.3 V or 1.8 V domains. Propagation delay ranges from 0.7 ns (min) to 7.0 ns (max) across supply voltages, with typical CPD = 16.6 pF at 3.3 V - critical for low-power, high-speed edge detection in ADAS sensor preprocessing stages.

FAQ

Can 74LVC1G17GW-Q100 interface a 5 V microcontroller GPIO with a 1.8 V FPGA input?

Yes. Its inputs tolerate up to 5.5 V independent of VCC, so with VCC = 1.8 V, it safely accepts 5 V logic highs from the microcontroller and outputs a clean 1.8 V-compatible signal to the FPGA. No external level-shifter is needed, and the Schmitt trigger ensures noise immunity on the 5 V line.

What is the maximum allowable capacitive load on the Y output?

The Y output drives up to 30 pF load capacitance while maintaining specified tpd ≤ 7.0 ns at VCC = 3.0 V. For loads exceeding 30 pF (e.g., long PCB traces or multiple fan-outs), propagation delay increases linearly - at 50 pF, tpd rises to ~9.5 ns. Use series termination if routing exceeds 5 cm on 50 Ω impedance-controlled traces.

Does the IOFF feature work when only GND is connected and VCC is floating?

No. IOFF activation requires VCC = 0 V (i.e., actively pulled to ground), not floating. If VCC is left unconnected, internal protection diodes may forward-bias, causing unpredictable leakage or latch-up. Always tie VCC to GND through a 0 Ω resistor or explicit ground connection during power-down states.

How does hysteresis change with supply voltage and temperature?

Hysteresis (VH) decreases slightly with lower VCC: e.g., 0.88 V at VCC = 5.5 V vs. 0.47 V at VCC = 1.8 V (−40 °C to +125 °C). Over temperature, VH varies ±5% across −40 °C to +125 °C at fixed VCC - confirmed in Table 8. This ensures consistent noise margin across full automotive operating range without recalibration.
