The 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.

Features of CD4543 BCD To 7-Segment Decoder:

• Low Symmetrical Output Resistance, Typically 100 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 2 N 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.

Applications of CD4543 BCD To 7-Segment Decoder:

• It is used as a programmable timer.
