Additional Details

The TC7WZ245FK comes in a US8 (Ultra Small 8-pin) package, ideally suited for space-constrained designs. The CMOS design ensures very low static power dissipation and high noise immunity. The high-speed characteristics are a result of advanced transistor design and fabrication. The inputs are equipped with protection circuits to guard against static discharge and voltage transients. A direction control input determines the direction of data flow.

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.
