CD4541BC Programmable Timer October 1987 Revised May 2002 CD4541BC Programmable Timer General Description Features 8 10 13 16 The CD4541BC Programmable Timer is designed with aAvailable division ratios 2 , 2 , 2 , or 2 16-stage binary counter, an integrated oscillator for use Increments on positive edge clock transitions with an external capacitor and two resistors, output control Built-in low power RC oscillator (±2% accuracy over logic, and a special power-on reset circuit. The special fea- temperature range and ±10% supply and ±3% over pro- tures of the power-on reset circuit are first, no additional cessing @ < 10 kHz) static power consumption and second, the part functions Oscillator frequency range ≈ DC to 100 kHz across the full voltage range (3V–15V) whether power-on reset is enabled or disabled.Oscillator may be bypassed if external clock is available (apply external clock to pin 3) Timing and the counter are initialized by turning on power, if the power-on reset is enabled. When the power isAutomatic reset initializes all counters when power turns already on, an external reset pulse will also initialize the on timing and counter. After either reset is accomplished, the External master reset totally independent of automatic oscillator frequency is determined by the external RC net- reset operation work. The 16-stage counter divides the oscillator frequency n Operates at 2 frequency divider or single transition by any of 4 digitally controlled division ratios. timer Q/Q select provides output logic level flexibility Reset (auto or master) disables oscillator during reset- ting to provide no active power dissipation Clock conditioning circuit permits operation with very slow clock rise and fall times Wide supply voltage range—3.0V to 15V High noise immunity—0.45 V (typ.) DD 5V–10V–15V parameter ratings Symmetrical output characteristics Maximum input leakage 1 μA at 15V over full tempera- ture range High output drive (pin 8) min. one TTL load Ordering Code: Order Number Package Number Package Description CD4541BCM M14A 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow CD4541BCN N14A 14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide Devices also available in Tape and Reel.
