HEF4541BP

Programmable timer

DESCRIPTION

The HEF4541B is a programmable timer which consists of

a 16-stage binary counter, an integrated oscillator to be

used with external timing components, an automatic

power-on reset and output control logic. The frequency of

the oscillator is determined by the external components

Rt and Ct within the frequency range 1 Hz to 100 kHz. This

oscillator may be replaced by an external clock signal at

input RS, the timer advances on the positive-going

transition of RS. A LOW on the auto reset input (AR) and

a LOW on the master reset input (MR) enables the internal

power-on reset. A HIGH level at input MR resets the

counter independent on all other inputs. Resetting

disables the oscillator to provide no active power

dissipation.

A HIGH at input AR turns off the power-on reset to provide

a low quiescent power dissipation of the timer. The

16-stage counter divides the oscillator frequency by

depending on the state of the address

inputs (A0, A1). The divided oscillator frequency is

available at output O. The phase input (PH) features a

complementary output signal. If the mode select input

(MODE) is LOW or HIGH the timer can be used

respectively as a single transition timer or 2n

frequency

divider.
