CD4541BE Datasheet

Timers & Support Products


CD4541BE 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. CD4541BE Features • Low Symmetrical Output Resistance, Typically 100Ω at VDD = 15V• Built-In Low-Power RC Oscillator• Oscillator Frequency Range . . . . . . . . . . DC to 100kHz• External Clock (Applied to Pin 3) can be Used Instead of Oscillator• Operates as 2N Frequency Divider or as a Single- Transition Timer• Q/Q Select Provides Output Logic Level Flexibility• AUTO or MASTER RESET Disables Oscillator During Reset to Reduce Power Dissipation• Operates With Very Slow Clock Rise and Fall Times• Capable of Driving Six Low Power TTL Loads, Three Low-Power Schottky Loads, or Six HTL Loads Over the Rated Temperature Range
