The TC7S04FU,LF: ROHS3 compliant, which simplifies compliance for global markets without requiring exemption documentation.
Single-gate inverter — signal cleanup in a tiny footprint
This is a single-gate inverter (one input, one output) from Toshiba's TC7S series — the simplest logic function, used to invert a digital signal or clean up a noisy edge. Quiescent current is just 1 µA max, so it adds negligible drain in battery-powered or always-on circuits.
Package options and board integration
Available in multiple surface-mount packages: 5-TSSOP, SC-70-5, SOT-353, and the supplier device package is 5-SSOP — all share a similar 5-pin footprint with 0.65 mm pitch, so the PCB layout is consistent across variants. The tape-and-reel option supports automated pick-and-place assembly for volume production.
Propagation delay and drive strength
Maximum propagation delay is 17 ns at 6V supply with a 50 pF load — fast enough for most low-to-moderate speed logic interfaces, like level translation or debounce cleanup. Output drive is symmetric: 2.6 mA source and 2.6 mA sink, which is typical for a single-gate CMOS buffer — enough to drive one or two standard logic inputs but not a long trace or high-capacitance load.
