MM54HC4049/MM74HC4049
Hex Inverting Logic Level Down Converter
MM54HC4050/MM74HC4050
Hex Logic Level Down Converter
General Description
The MM54HC4049/MM74HC4049 and the MM54HC4050/
MM74HC4050 utilize advanced silicon-gate CMOS technology,
and have a modified input protection structure that enables
these parts to be used as logic level translators which
will convert high level logic to a low level logic while operating
from the low logic supply. For example, 0±15V CMOS
logic can be converted to 0±5V logic when using a 5V supply.
The modified input protection has no diode connected
to VCC, thus allowing the input voltage to exceed the supply.
The lower zener diode protects the input from both positive
and negative static voltages. In addition each part can be
used as a simple buffer or inverter without level translation.
The MM54HC4049/MM74HC4049 is pin and functionally
compatible to the CD4049BM/CD4049BC and the
MM54HC4050/MM74HC4050 is compatible to the
CD4050BM/CD4050BC
