74HC4050; Hex high-to-low level shifter
Philips Semiconductors Product specification
Hex high-to-low level shifter 74HC4050
FEATURES Output capability: standard ICC category: SSI
GENERAL DESCRIPTIONThe 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.
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
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.
APPLICATIONS Converting 15 V logic (“4000B” series) down to 2 V logic.
QUICK REFERENCE DATAGND= 0 V; Tamb =25 °C; tr =tf= 6 ns
Notes CPD is used to determine the dynamic power dissipation (PD in μW): =CPD × VCC2 × fi +∑ (CL × VCC2 × fo) where:= input frequency in MHz= output frequency in MHz= output load capacitance in pF
VCC= supply voltage in V
∑ (CL × VCC2 × fo)= sum of outputs
