DIP	HCF4050BEY
SOP	HCF4050BM1	HCF4050M013TR

The input high level signal (VIH) can exceed the VDD supply voltage when these devices are used for logic level conversions. This device is intended for use as CMOS to DTL/TTL converters and can drive directly two DTL/TTL loads (VDD=5V, VOL≤0.4V and IOL≤3.2mA.
