CD4541B Description
of ‘B’ Series CMOS Devices” Description CD4541B programmable timer consists of a 16-stage binary counter, an oscillator that is controlled by external R-C ponents (2 resistors and a capacitor), an automatic power-on reset circuit, and output control logic. The counter increments on positive-edge clock transitions and can also be reset via the MASTER RESET input. The desired stage is chosen using time-select inputs A...
CD4541B Key Features
- Low Symmetrical Output Resistance, Typically 100Ω at VDD = 15V
