Bare Die Product Detail: CD4541B

Rate Multiplier/Frequency Divider/Timer:
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
