REI Datasheet MM54HC4049, MM74HC4049 / MM54HC4050, MM74HC4050 Hex Inverting Logic Level Down Converter / Hex Logic Level Down Converter The MM54HC4049/MM74HC4049 and the MM54HC4050/MM74HC4050 utilize advanced silicongate CMOS technology, and have a modiied 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 modiied 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. Rochester Electronics Manufactured Components Quality Overview Rochester branded components are manufactured using either die/wafers purchased from the original suppliers or Rochester wafers recreated from the original IP. All recreations are done with the approval of the OCM. • ISO-9001 • AS9120 certiication • Qualiied Manufacturers List (QML) MIL-PRF-38535 • Class Q Military • Class V Space Level • Qualiied Suppliers List of Distributors (QSLD) • Rochester is a critical supplier to DLA and meets all industry and DLA standards. Parts are tested using original factory test programs or Rochester developed test solutions to guarantee product meets or exceeds the OCM data sheet. Rochester Electronics, LLC is committed to supplying products that satisfy customer expectations for quality and are equal to those originally supplied by industry manufacturers.
