Diodes Incorporated 74LVC2G14FZ4-7

Overview

74LVC2G14FZ4-7 from Diodes Incorporated is a dual Schmitt trigger inverter IC in X2-DFN1410-6 package (1.4 mm × 1.0 mm × 0.4 mm, 0.5 mm pad pitch), 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 supports partial power-down via IOFF, enables voltage-level shifting between mixed-voltage domains, and is used in signal conditioning for USB, I²C, and reset circuits.

For engineers reviewing the 74LVC2G14FZ4-7 datasheet, 74LVC2G14FZ4-7 pinout, 74LVC2G14FZ4-7 application, or 74LVC2G14FZ4-7 equivalent, key selection criteria include Schmitt-trigger hysteresis (min 0.15 V at 1.8 V), propagation delay (max 6.0 ns at 3.3 V), IOFF leakage (<±10 μA), input threshold symmetry, and DFN thermal resistance (θJA = 430 °C/W).

Technical Context

This device implements two independent Schmitt-trigger inverters with push-pull outputs and IOFF circuitry that disables outputs during power-down to prevent backflow current. Its input thresholds are supply-dependent: VT+ ranges from 0.70 V (1.8 V VCC) to 3.60 V (5.5 V VCC), while VT− ranges from 0.25 V to 2.30 V, yielding hysteresis ∆VT from 0.15 V to 1.70 V.

The logic function Y = A̅ is implemented with rail-to-rail CMOS-compatible outputs, supporting bidirectional level translation across 1.65–5.5 V domains. Input capacitance is 3.5 pF typical, and power dissipation capacitance is 20 pF at 3.3 V, enabling low-noise, low-glitch operation in noise-prone digital interfaces.

FAQ

What is the maximum recommended operating temperature for 74LVC2G14FZ4-7?

The device is rated for continuous operation from −40°C to +125°C ambient temperature. Junction temperature must not exceed +150°C; with θJA = 430 °C/W and typical power dissipation <0.5 mW, derating is unnecessary below 85°C ambient in standard FR-4 layouts.

Can 74LVC2G14FZ4-7 be used with a 1.5 V supply?

No. The absolute minimum recommended supply is 1.65 V per datasheet Section 6. Operating below this risks undefined logic states, increased propagation delay variation, and failure to meet VOH/VOL specifications - even though data retention is guaranteed down to 1.5 V.

Does the IOFF feature require external biasing or control signals?

No. IOFF activates automatically when VCC is removed or falls below ~0.8 V; no enable pin or external circuitry is needed. Output impedance rises to >10 MΩ, blocking current flow in both directions without additional components.

Is the X2-DFN1410-6 package compatible with standard reflow profiles?

Yes. As a moisture sensitivity level 1 device with NiPdAu terminations, it supports IPC/JEDEC J-STD-020-compliant lead-free reflow (peak 260°C, 60 sec max above 217°C). Recommended pad layout matches Diodes' published footprint (C = 1.000 mm, G = 0.200 mm).
