Programmable Timer

General Description

The CD4541BC Programmable Timer is designed with 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 special fea-

tures of the power-on reset circuit are first, no additional

static power consumption and second, the part functions

across the full voltage range (3V–15V) whether power-on

reset is enabled or disabled.

Timing and the counter are initialized by turning on power,

if the power-on reset is enabled. When the power is

already on, an external reset pulse will also initialize the

timing and counter. After either reset is accomplished, the

oscillator frequency is determined by the external RC net-

work. The 16-stage counter divides the oscillator frequency

by any of 4 digitally controlled division ratios.

Ordering Code:

Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
