1 / 7 page UNISONIC TECHNOLOGIES CO., LTD CD4541 CMOS IC www.unisonic.com.tw 1 of 7 Copyright © 2012 Unisonic Technologies Co., LTD QW-R502-037.C PROGRAMMABLE TIMER DESCRIPTION The CD4541 programmable timer comprise a 16-stage binary counter, an integrated oscillator for use with an external capacitor and two resistors, output control logic, and a special power-on reset circuit. The counter divides the oscillator frequency by any of 4 digitally controlled division ratios. FEATURES * Operates at 2 n frequency divider or as single transition timer * Increments on positive edge clock transitions * Wide supply voltage range: 3.0V ~ 15V * Built-in low power RC oscillator * Oscillator frequency range ~ DC to 100 kHz * External clock applied to Pin 3 can be used instead of * oscillator * Available division ratios 2 8, 210, 213, or 216 * High noise immunity: 0.45 VDD (typ) * Master reset totally independent of automatic reset operation * Automatic reset initializes all counters when power turns on * Q/Q select provides output logic level flexibility * High output drive min. one TTL load * Maximum input leakage 1μA at 15V over full temperature * range DIP-14 SOP-14 TSSOP-14 ORDERING INFORMATION Ordering Number Package Packing Lead Free Halogen Free CD4541L-D14-T CD4541G-D14-T DIP-14 Tube CD4541L-S14-R CD4541G-S14-R SOP-14 Tape Reel CD4541L-S14-T CD4541G-S14-T SOP-14 Tube CD4541L-P14-R CD4541G-P14-R TSSOP-14 Tape Reel CD4541L-P14-T CD4541G-P14-T TSSOP-14 Tube |
