Diodes Incorporated 74LVC2G14DW-7

Overview

74LVC2G14DW-7 from Diodes Incorporated is a dual Schmitt trigger inverter IC in SOT363 package, operating from 1.65V to 5.5V supply, with 5.5V-tolerant inputs and ±24mA output drive at 3.0V. It implements two independent inverting logic functions with hysteresis (ΔVT = 0.4–1.7V), supports partial power-down via IOFF, and is used for noise-immune signal conditioning in mixed-voltage I/O interfaces.

For engineers reviewing the 74LVC2G14DW-7 datasheet, 74LVC2G14DW-7 pinout, 74LVC2G14DW-7 application, or 74LVC2G14DW-7 equivalent, key selection criteria include input hysteresis width, IOFF leakage (<±20μA), propagation delay (≤6.7ns at 3.3V), 3000-unit tape-and-reel availability, and SOT363 thermal resistance (θJA = 371°C/W).

Technical Context

This device integrates two independent Schmitt-trigger inverters on a single die, each featuring asymmetric input thresholds (VT+ = 1.3–3.8V, VT− = 0.6–2.5V at VCC = 3–5.5V) to reject noise on slow-rising/falling signals. Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0V while inputs remain at up to 5.5V.

The logic function Y = A̅ is implemented with push-pull CMOS outputs capable of sinking or sourcing up to 32mA at 4.5V. Input capacitance is 3.5pF typical, and power consumption remains ultra-low (ICC ≤ 40μA), making it suitable for battery-powered and space-constrained applications requiring robust level shifting.

FAQ

What is the maximum input frequency supported by the 74LVC2G14DW-7?

The device does not specify a maximum clock frequency, but its propagation delay (tPD ≤ 6.7ns at 3.3V, 125°C) supports reliable toggling up to ~150MHz under typical load conditions. Actual usable frequency depends on output load capacitance and signal rise/fall times-designers should verify timing margins using the switching characteristics table and CL = 30–50pF test conditions.

Can the 74LVC2G14DW-7 be used for level shifting between 1.8V and 5V logic domains?

Yes-the inputs tolerate up to 5.5V regardless of VCC, and outputs swing rail-to-rail. When powered from 1.8V, it accepts 5V inputs and produces 0–1.8V outputs; when powered from 5V, it accepts 1.8V inputs and produces 0–5V outputs. No external resistors or translators are needed, provided output load current stays within ±24mA limits.

Does the IOFF feature require any external control signals or configuration?

No-IOFF is fully automatic and requires no external enable/disable pins or configuration. When VCC drops to 0V (or near-zero), the internal IOFF circuitry activates and places both outputs in high-impedance state, blocking current flow from powered inputs into the unpowered VCC/GND rails. This behavior is intrinsic to the silicon design and operates across the full −40°C to +125°C temperature range.

Is the SOT363 package of the 74LVC2G14DW-7 compatible with standard reflow soldering profiles?

Yes-the SOT363 package has moisture sensitivity level 1 per J-STD-020 and is qualified for standard lead-free reflow profiles (peak temperature ≤ 260°C). Its matte tin-plated leads meet MIL-STD-202 Method 208 solderability requirements. Recommended pre-bake is not required unless exposed to >60% RH for >168 hours; standard PCB assembly processes apply.
