Diodes Incorporated 74LVC2G17FW4-7

Overview

74LVC2G17FW4-7 from Diodes Incorporated is a dual Schmitt trigger buffer IC in X2-DFN1010-6 package (1.0 mm × 1.0 mm × 0.4 mm), operating from 1.65 V to 5.5 V supply, with 5.5 V-tolerant inputs and ±24 mA output drive at 3.0 V. It enables noise-immune signal conditioning in mixed-voltage I/O interfaces for portable consumer electronics.

For engineers reviewing the 74LVC2G17FW4-7 datasheet, 74LVC2G17FW4-7 pinout, 74LVC2G17FW4-7 application, or 74LVC2G17FW4-7 equivalent, key selection criteria include input hysteresis (min 0.15 V at 1.8 V), propagation delay (max 5.7 ns at 3.3 V), IOFF-enabled partial power-down isolation, and DFN1010 footprint compatibility with space-constrained PCB layouts.

Technical Context

This device implements two independent non-inverting Schmitt trigger buffers with push-pull outputs and IOFF circuitry that disables outputs during power-down to prevent backflow current. Its input threshold hysteresis (ΔVT) ranges from 0.15 V to 1.90 V depending on VCC, enabling robust noise rejection in noisy digital environments.

The logic function Y = A is implemented with rail-to-rail CMOS-compatible outputs, 5.5 V input tolerance across all supply voltages (1.65–5.5 V), and guaranteed operation from –40 °C to +125 °C ambient temperature. Input capacitance is 3.5 pF typical, supporting high-speed signal integrity in compact layouts.

FAQ

What is the minimum recommended decoupling capacitance for 74LVC2G17FW4-7?

A 0.1 μF X7R ceramic capacitor placed within 2 mm of the VCC pin (Pin 5) and GND (Pin 2) is required per Diodes' layout guidelines. This mitigates supply rail noise induced by fast output transitions and ensures stable Schmitt trigger thresholds across temperature and load conditions.

Can 74LVC2G17FW4-7 be used with 1.2 V logic inputs?

No - the absolute minimum VCC is 1.65 V, and input thresholds scale with VCC. At 1.65 V supply, VT+ is 0.70–1.50 V and VT− is 0.25–0.90 V; a 1.2 V input would fall within the undefined region and cause metastability or excessive current draw.

Does the IOFF feature require external control signals?

No - IOFF is fully automatic and activated whenever VCC is below ~0.8 V. No enable pin or external bias is needed; the internal circuitry disables both outputs (1Y and 2Y) to high-impedance state, blocking current flow even if inputs remain at 5.5 V.

Is the X2-DFN1010-6 package lead-free and RoHS compliant?

Yes - the 74LVC2G17FW4-7 uses NiPdAu terminal finish and contains no intentionally added lead, bromine, chlorine, or antimony compounds. It complies fully with EU RoHS 2011/65/EU and RoHS 3 2015/863/EU directives and is certified "Green" per Diodes' specification.
