Six inverters with Schmitt-trigger inputs for noisy environments
The Texas Instruments SN74LV14AMPWREP is a hex inverter with Schmitt-trigger inputs, part of the 74LV low-voltage CMOS family. It contains six independent inverter circuits, each with a single input, and is housed in a 14-TSSOP surface-mount package. The Schmitt-trigger action provides clean switching on slow or noisy input signals, making it a natural fit for signal conditioning, debouncing, and interface buffering in industrial control, avionics, and downhole instrumentation where the -55°C to 125°C military temperature range is required.
Wide supply range and output drive
The supply range spans 2V to 5.5V, covering 3.3V and 5V logic rails and allowing mixed-voltage designs without a separate level translator. Each output can source or sink 12mA, enough to drive a standard CMOS load or a single TTL gate. Quiescent current is a maximum of 20 µA, so the part adds negligible standby draw in battery-powered or always-on subsystems.
Propagation delay and timing margin
Maximum propagation delay is 10.6ns at 5V with a 50pF load. At lower supply voltages the delay increases, but the 74LV family is fast enough for most logic-level interfaces below 50 MHz. The 10.6ns figure gives a comfortable timing margin when the part is used as a clean-up buffer for a sensor output or a clock fan-out.
Lifecycle and sourcing
The SN74LV14AMPWREP is listed as Active with no end-of-life notice. It is ROHS3 compliant. For current pricing and availability, submit an RFQ — we source through independent distribution and confirm availability and pricing at quote time. No LTB risk for new designs.
