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.
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
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.
The SN74LVC3G14DCUT is an active, current-production TI part. The part is also available in Cut Tape (CT) for prototyping quantities.
