Additional Details

The TC7WZ14FK comes in a US8 (Ultra Small 8-pin) package, making it ideal for space-constrained applications. Its CMOS design ensures low static power consumption and high noise immunity. The device's high-speed operation is achieved through optimized transistor design and fabrication processes. The inputs are equipped with protection circuits against static discharge and transient excess voltage. The Schmitt trigger inputs provide hysteresis, preventing oscillation with slowly changing or noisy input signals.

The output can drive 10 LSTTL loads. Propagation delay times are typically 2.6ns at 5V, 3.7ns at 3.3V and 7.2ns at 1.8V supply voltage. The input capacitance is typically 3pF.
