六角反相逻辑电平下变频器。十六进制逻辑电平下变频器 Hex Inverting Logic Level Down Converter . Hex Logic Level Down Converter
General Description
The MM74HC4049 and the 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 allow ing 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 MM74HC4049 is pin and functionally compatible to the CD4049BC and the MM74HC4050 is compatible to the CD4050BC.
