Triple Schmitt-trigger inverter for mixed-voltage signal conditioning
The Texas Instruments SN74LVC3G14DCUT packs three independent Schmitt-trigger inverters into a compact 8-VSSOP package. Its 1.65 V to 5.5 V supply range lets it bridge 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without a separate level translator — useful when a 3.3 V MCU needs to clean up a 5 V sensor's noisy edge or when a 1.8 V FPGA I/O must drive a 3.3 V peripheral. The Schmitt-trigger inputs add built-in hysteresis, so slow-rising or noisy signals get a clean, jitter-free digital output without external RC filtering. Each of the three channels can source or sink 32 mA, enough to drive an LED indicator or a short PCB trace directly.
4.3 ns propagation delay — timing margin for high-speed paths
With a maximum propagation delay of 4.3 ns at 5 V and 50 pF load, this inverter keeps signal skew tight in clock distribution or deglitching circuits. The 10 µA max quiescent current means it won't eat into a tight power budget when the channels are idle.
Industrial temperature range and active lifecycle
Rated for -40°C to 125°C, the SN74LVC3G14DCUT is a candidate for outdoor telecom cabinets, under-hood automotive modules, and factory-floor I/O. The part carries an Active lifecycle status and is ROHS3 compliant.
Package and footprint: 8-VSSOP
Housed in an 8-VFSOP (0.091", 2.30 mm width) which the supplier device package lists as 8-VSSOP. The fine-pitch, small-body footprint saves board area and is a direct fit for space-constrained designs like handheld instruments or sensor interface modules.
Sourcing and availability
The SN74LVC3G14DCUT is an active, current-production TI part. The part is also available in Cut Tape (CT) for prototyping quantities. For a BOM line that needs this exact triple Schmitt-trigger inverter, the supply channel is open — no allocation drama expected for a standard 74LVC logic part.
