Nexperia USA Inc. 74LVC3G17GT,115

Overview

74LVC3G17GT,115 from Nexperia is a triple non-inverting Schmitt trigger buffer with 5 V tolerant inputs, designed for signal conditioning in mixed-voltage digital systems. It operates from 1.65 V to 5.5 V, delivers ±24 mA output drive at 3.0 V, and features IOFF circuitry for partial power-down protection. It is used in noise-prone interface translation between 3.3 V and 5 V logic domains.

For engineers reviewing the 74LVC3G17GT,115 datasheet, 74LVC3G17GT,115 pinout, 74LVC3G17GT,115 application, or 74LVC3G17GT,115 equivalent, key selection considerations include hysteresis voltage (0.40–1.40 V), propagation delay (1.0–5.4 ns), 5.5 V input overvoltage tolerance, and XSON8 package compatibility with high-density PCB layouts.

Technical Context

This device implements three independent Schmitt-trigger input buffers with non-inverting logic function, enabling robust waveform shaping and noise immunity in digital signal paths. Each channel exhibits defined positive-going (VT+) and negative-going (VT−) thresholds-e.g., VT+ = 1.30–2.40 V and VT− = 0.60–1.70 V at VCC = 3.0 V-yielding hysteresis (VH) of 0.40–1.40 V across temperature and supply conditions.

The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current up to ±50 mA and supporting hot-insertion and partial power-down system architectures. Inputs tolerate up to 5.5 V regardless of VCC level, allowing direct interfacing with legacy 5 V TTL or CMOS sources without level-shifting components.

FAQ

What is the maximum input voltage the 74LVC3G17GT,115 can withstand when VCC = 1.8 V?

The 74LVC3G17GT,115 supports input voltages up to 5.5 V regardless of VCC level, including at 1.8 V supply. This is confirmed in Table 5 (Limiting Values) and Table 6 (Recommended Operating Conditions), where VI(max) = 5.5 V applies across the full 1.65–5.5 V VCC range. No external clamping is required.

Does the 74LVC3G17GT,115 support hot insertion in live backplanes?

Yes. Its IOFF circuitry disables outputs when VCC = 0 V, limiting power-off leakage current to ±2 μA and blocking backflow current up to ±50 mA. This meets hot-swap requirements per IEC 61000-4-2 and enables safe insertion into powered systems without disrupting upstream logic or causing latch-up.

How does the hysteresis voltage change with temperature and supply voltage?

Hysteresis (VH = VT+ − VT−) varies with VCC and temperature: at VCC = 3.0 V, VH is 0.40–1.40 V over −40 °C to +125 °C (Table 8). At VCC = 5.5 V, VH expands to 0.70–1.90 V. This monotonic increase ensures consistent noise margin across operating conditions without calibration.

Can the 74LVC3G17GT,115 drive a 50 Ω transmission line directly?

Yes. With ±24 mA output drive at VCC = 3.0 V and VOL ≤ 0.55 V / VOH ≥ 2.3 V (Table 7), it can terminate and drive a 50 Ω line with <10% overshoot and <1 ns rise/fall times (per Fig. 10 and Table 11), provided trace impedance is controlled and CL ≤ 50 pF.
