Nexperia USA Inc. 74LVC2G17GV,125

Overview

74LVC2G17GV from Nexperia is a dual 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, features IOFF partial power-down protection, and supports operation from –40 °C to +125 °C. It is used in noise-prone interface translation between 3.3 V and 5 V logic domains.

For engineers reviewing the 74LVC2G17GV datasheet, 74LVC2G17GV pinout, 74LVC2G17GV application, or 74LVC2G17GV equivalent, key selection criteria include Schmitt-trigger hysteresis (min 0.40 V at 3.0 V), 5.5 V input overvoltage tolerance, IOFF-enabled bus hold during power sequencing, propagation delay ≤5.4 ns at 5.5 V, and SC-74 (SOT457) package compatibility with high-density PCB layouts.

Technical Context

This device implements two independent non-inverting Schmitt-trigger buffers in a single 6-pin SC-74 package. Each channel provides hysteresis (VH = 0.40–1.40 V depending on VCC), enabling robust waveform shaping of slow or noisy digital signals. The IOFF circuit actively disables outputs when VCC = 0 V, preventing back-current flow during partial power-down sequences.

Input thresholds are rail-relative: VT+ ranges from 1.30 V to 3.80 V and VT− from 0.60 V to 2.50 V across 1.8–5.5 V supply, ensuring reliable switching even with degraded edge rates. Static current consumption remains below 4 μA at 5.5 V, supporting low-power always-on monitoring paths in industrial control and sensor interface applications.

FAQ

Does 74LVC2G17GV support true bidirectional signal translation?

No. The 74LVC2G17GV is a unidirectional non-inverting buffer with Schmitt-trigger inputs. It does not provide automatic direction sensing or bus transceiver functionality. Its 5 V tolerant inputs allow it to accept signals from higher-voltage sources, but outputs are strictly referenced to VCC and cannot drive 5 V logic without additional level-shifting circuitry.

What is the minimum recommended load capacitance for stable Schmitt-trigger operation?

The device is characterized with CL = 30–50 pF in dynamic testing, and no minimum load capacitance is specified. Operation remains stable down to near-zero capacitive load (e.g., direct connection to CMOS inputs). However, for optimal noise immunity in high-EMI environments, a 10–33 pF capacitor to ground at each output is recommended to dampen ringing without degrading propagation delay.

Can 74LVC2G17GV be used with VCC = 1.8 V while driving 3.3 V logic inputs?

No. While inputs tolerate up to 5.5 V, outputs swing only from GND to VCC. At VCC = 1.8 V, VOH is typically 1.7 V - insufficient to meet VIH(min) = 2.0 V for standard 3.3 V CMOS inputs. To drive 3.3 V logic, VCC must be ≥2.7 V (VOH ≥2.2 V) or an external level shifter must be used.

How does the IOFF feature behave during brown-out conditions?

IOFF activates only when VCC falls below approximately 0.2 V. During gradual brown-out (e.g., VCC dropping from 3.3 V to 0.5 V), the device continues normal operation until VCC approaches 0 V. For controlled power-down sequencing, pair with a supervisor IC that asserts reset before VCC drops below 0.5 V to ensure deterministic output disable prior to full collapse.
