CD4541B Overview
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
- 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 SingleTransition 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
