HEF4541B-Q100

Programmable timer

Rev. 3 — 25 November 2021

Product data sheet

1. General description

The HEF4541B-Q100 is a programmable timer. It 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 external components R_TCand C_TCdetermines the frequency of the

oscillator within the frequency range 1 Hz to 100 kHz. An external clock signal at input RS can

replace the oscillator. 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 2⁸, 2¹⁰, 2¹³or 2¹⁶depending 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. When the mode select input (MODE) is

LOW the timer is a single transition timer and when HIGH the timer is a 2ⁿfrequency divider.

It operates over a recommended V_DDpower supply range of 3 V to 15 V referenced to V_SS(usually

ground). Unused inputs must be connected to V_DD, V_SS, or another input.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.
