Product details

The Toshiba TC7SZ14F,LJ(CT is a single-gate inverter from the TC7SZ series of high-speed CMOS logic, with Schmitt trigger inputs. It takes one input and delivers a clean inverted output, with built-in hysteresis that rejects noise and slow edges. Typical applications include signal conditioning, oscillator circuits, switch debounce, and general-purpose glue logic where a single inverting buffer with hysteresis is needed.

The max propagation delay is 5.9 ns at 5 V with a 50 pF load.

Quiescent current is 1 µA max, so the gate adds negligible static power to the board.

Packaging and procurement options

This order code suffix (LJ(CT) indicates supply in Cut Tape (CT) form. The same device is also available in Tape & Reel (TR). The package is SC-74A (SOT-753).

Frequently asked questions

Can TC7SZ14F replace a 74HC14?

The 74HC14 is a hex inverter with Schmitt trigger; the TC7SZ14F is a single-gate device. Functionally the Schmitt trigger behaviour is the same, but you would need six TC7SZ14F parts to replace one 74HC14, and the pinouts differ. For a single-gate replacement, the TC7SZ14F is a direct fit in terms of logic function and supply range.

What is the propagation delay of TC7SZ14F?

At lower supply voltages the delay increases; expect roughly 10 ns at 3.3 V and 20 ns at 1.8 V under similar capacitive loading.
