Texas Instruments CD54HC4049
The ’HC4049 and ’HC4050 are fabricated with high-speed silicon gate technology. They have a modified input protection structure that enables these parts to be usedas logic level translators which convert high-level logic to a lowlevel logic while operating off the low-level logic supply.| Part No. | CD54HC4049 |

FEATURES
DESCRIPTION
● Typical Propagation Delay: CL = 15pF, TA = 25oC 6ns at VCC = 5V,● High-to-Low Voltage Level Converter for up to Vl = 16V
● Fanout (Over Temperature Range) - Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads - Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads
● Wide Operating Temperature Range . . . –55oC to 125oC
● Balanced Propagation Delay and Transition Times
● Significant Power Reduction Compared to LSTTL Logic ICs
● HC Types - 2V to 6V Operation - High Noise Immunity: NIL = 30%, NIH = 30%of VCC at VCC = 5V Pinout For example, 15-V input pulse levels can be down-converted to 0-V to 5-V logic levels. The modified input protection structure protects the input from negative electrostatic discharge. These parts also can be used as simple buffers or inverters without level translation. The ’HC4049 and ’HC4050 are enhanced versions of equivalent CMOS types. Ordering Information PART NUMBER CD54HC4049F3A CD54HC4050F3A CD74HC4049E TEMP. RANGE (oC...
