Single-gate inverter for general-purpose logic
The Toshiba TC7SZ04F,LJ(CT is a single-gate CMOS inverter from the TC7SZ series, designed for board-level logic inversion in mixed-voltage systems. The device delivers 32 mA output drive at both high and low levels, and its 4.3 ns propagation delay at 5V with 50 pF load keeps signal skew low in clock or data paths. Quiescent current is a maximum of 2 µA, which matters for battery-powered or always-on circuits where every microamp counts.
At 5V and 50 pF load, the maximum propagation delay is 4.3 ns. That figure is the worst-case spec across temperature and voltage, so it's the number to use in timing closure. If your bus has a 10 ns cycle window, this inverter leaves about 5.7 ns of margin for the rest of the path. At lower supply voltages the delay will be longer — the datasheet curve (not reproduced here) shows the typical increase. For a 3.3V rail, budget closer to 6–7 ns if you need a conservative estimate.
For applications that need -40°C to 125°C, look at the 7UL1G00 series (a NAND gate, not an inverter) or other Toshiba parts in the 7UL family that carry the wider range.
