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.
FEATURES
• Output capability: standard
• ICC category: SSI
GENERAL DESCRIPTION
The actual input switch level remains related to the VCC
and is the same as mentioned in the family characteristics.
The 74HC4050 is a high-speed Si-gate CMOS device and
is pin compatible with the “4050” of the “4000B” series. It
is specified in compliance with JEDEC standard no. 7A.
APPLICATIONS
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
• Converting 15 V logic (“4000B” series) down to 2 V logic.

Notes
1. CPD is used to determine the dynamic power dissipation (PD in µW):
2
PD = CPD × VCC2 × fi +∑ (CL × VCC × fo) where:
fi = input frequency in MHz
fo = output frequency in MHz
CL = output load capacitance in pF
VCC = supply voltage in V
∑ (CL × VCC2 × fo) = sum of outputs
