5 V Schmitt-trigger inverter — noise margin and timing
The TC7SET14F,LF is a single-channel inverter with Schmitt-trigger input, part of Toshiba's TC7SET logic family. The Schmitt-trigger thresholds — low-level at 0.5 V to 0.6 V, high-level at 1.9 V to 2.1 V — provide clean switching on noisy or slow-ramp input signals, rejecting ripple that would cause oscillation in a standard inverter. Maximum propagation delay is 9.6 ns at 5 V driving a 50 pF load, which sets the data-rate ceiling for this gate in a typical 5 V logic chain.
Package and footprint — SC-74A / SOT-753
Housed in a 5-pin SC-74A / SOT-753 package with a 0.95 mm pitch, the TC7SET14F,LF is a surface-mount device supplied in Cut Tape form. The supplier device package designation is SMV. This package is identical to the TC7SET14FU,LJ(CT variant — the two order codes share the same footprint, pinout, and parametric thresholds, so a BOM line specified for one accepts the other without a board spin.
Lifecycle and compliance — active, RoHS
It is RoHS compliant per the manufacturer's declaration. For current builds, there is no last-time-buy risk.
