It is specified in compliance with JEDEC standard no. 7A. The 74HC4050 provides six non-inverting buffers with a modified input protection structure, which has no diode connected to VCC. Input voltages of up to 15 V may QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf = 6 ns TYPICAL SYMBOL tPHL / tPLH CI CPD Notes 1. CPD is used to determine the dynamic power dissipation (PD in µW): PD = CPD Ч VCC2 Ч fi + (CL Ч VCC2 Ч fo) where: fi = input frequency in MHz fo = output frequency in MHz CL = output load capacitance in pF VCC = supply voltage in V (CL Ч VCC2 Ч fo) = sum of outputs ORDERING INFORMATION See "74HC/HCT/HCU/HCMOS Logic Package Information". PARAMETER propagation delay nA to nY input capacitance power dissipation capacitance per buffer note 1 CONDITIONS HC CL = 15 pF; VCC = 5 V 7 3.5 14 74HC4050 therefore be used. This feature enables the non-inverting buffers to be used as logic level translators, which will convert high level logic to low level logic, while operating from a low voltage power supply. For example 15 V logic ("4000B series") can be converted down to 2 V logic. The actual input switch level remains related to the VCC and is the same as mentioned in the family characteristics.
