Diodes Incorporated 74LVC1G14FW4-7

Overview

74LVC1G14FW4-7 from Diodes Incorporated is a single-channel Schmitt-trigger inverter IC in a 1.0 mm × 1.0 mm X2-DFN1010-6 package, operating from 1.65 V to 5.5 V supply, with 5.5 V-tolerant inputs, ±24 mA output drive at 3.3 V, and IOFF partial power-down protection. It enables robust signal conditioning in mixed-voltage digital interfaces.

For engineers reviewing the 74LVC1G14FW4-7 datasheet, 74LVC1G14FW4-7 pinout, 74LVC1G14FW4-7 application, or 74LVC1G14FW4-7 equivalent, key selection criteria include hysteresis width (0.35–1.20 V), propagation delay (0.7–6.5 ns), input voltage tolerance, IOFF leakage (<±10 µA), and DFN thermal resistance (θJA = 445 °C/W).

Technical Context

This device implements a positive Boolean inversion function (Y = A̅) with Schmitt-trigger input thresholds-VT+ ranges from 0.70 V (1.65 V VCC) to 3.33 V (5.5 V VCC), and VT− from 0.30 V to 2.35 V-providing noise immunity in noisy environments. Its IOFF circuit actively disables outputs during power-down to prevent backflow current.

The logic gate supports wide-voltage operation across 1.65–5.5 V while maintaining rail-to-rail output swing and 5.5 V input tolerance, enabling level-shifting between 1.8 V, 2.5 V, 3.3 V, and 5 V domains without external biasing. All electrical characteristics are specified over −40°C to +125°C.

FAQ

What is the maximum operating temperature for 74LVC1G14FW4-7?

The device is fully specified from −40°C to +125°C ambient temperature. Junction temperature may reach +150°C under worst-case power dissipation and thermal conditions. Thermal resistance θJA is 445 °C/W for the X2-DFN1010-6 package, so derating is required above 85°C ambient if power exceeds ~22 mW.

Can 74LVC1G14FW4-7 be used with a 1.8 V supply and 3.3 V input signals?

Yes. The input is rated for 0–5.5 V regardless of VCC, so 3.3 V signals are safely accepted at 1.8 V supply. Output swing will be rail-to-rail (0–1.8 V), preserving logic levels for downstream 1.8 V receivers. No level shifter is needed.

Does the IOFF feature require external pull-up/down resistors?

No. IOFF is an internal circuit that automatically places the output in high-impedance state when VCC = 0 V. External resistors are unnecessary for IOFF operation, though unused inputs must be tied to VCC or GND per recommended operating conditions to prevent floating states.

Is the X2-DFN1010-6 package compatible with standard reflow profiles?

Yes. The package is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) and supports standard lead-free reflow profiles (peak ≤260°C). Its wettable flanks enable post-reflow AOI verification, and the 0.35 mm pad pitch is compatible with fine-pitch stencil printing.
