Bare Die Product Detail: CD4049UB

Inverting Buffer/Driver:
The CD4049UB features logic level conversion using single supply voltage. Primary use is as CMOS to TTL/DTL converter driving up to X2 TTL/DTL loads. The device finds use where low power dissipation and/or high noise immunity is desired.
This bare die is well suited for use in high reliability circuits. It is a direct replacement for MOT / ON Semi MC14049UB, Texas Instruments (TI) CD4049UBH and obsolete Fairchild & National CD4049UB.
  • High Input Voltage up to 20V
  • Logic level conversion using only one supply voltage
  • Inputs allow voltages greater than VDD
  • High Source and Sink Current
  • x2 TTL load drive
  • Specified at 5V, 10V & 15V
  • Low Input Current:  1.0µA
  • High Noise Immunity Characteristic of CMOS Devices
  • Military Temperature Range for High Reliability
  • Committed long term support with no die mask changes.

  • CMOS to DTL or TTL Hex Converters
  • CMOS Current Sink or Source Drivers
  • CMOS High-to-Low Logic Level Converters
