CD4541BPWR

CD4541B programmable timer consists of a 16-stage binary counter, an oscillator that is controlled by external R-C components (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.

Key features

• Low Symmetrical Output Resistance, Typically 100Ω at V_DD = 15V
