Bare Die Data Sheet: CD4541B

The CD4541B programmable timer consists of a 16-stage binary counter, integrated oscillator for use with an external capacitor and x2 resistors, an automatic power-on reset circuit and output control logic
This bare die is suited for hybrid & MCM designers needing high reliability, high integration & stability at temperature. This part is a direct replacement for Fairchild (FCH), Harris, RCA or Texas Instruments (TI) CD4541B or CD4541BH.
Features:
** END OF LIFE ** NOT RECOMMENDED FOR NEW DESIGN
  • Available outputs 28, 210, 213 or 216
  • Built-in low-power RC oscillator ≈ DC to 100kHz
  • External clock option (Pad 3) overrides oscillator
  • Use as 2n frequency divider or single transition timer
  • Q /Q select provides output logic level flexibility
  • Auto or master reset disables oscillator for lower PD
