HEF4541B Programmable timer Rev. 5 — 15 December 2015 Product data sheet 1. General 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 R and C within the frequency range 1Hz to 100kHz. This oscillator may TC TC 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 28, 210, 213 or 216 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. When the mode select input (MODE) is LOW the timer is a single transition timer and when HIGH the timer is a 2n frequency divider. It operates over a recommended V power supply range of 3V to 15 V referenced to V DD SS (usually ground). Unused inputs must be connected to V , V , or another input. DD SS 2.

HEF4541B Nexperia Programmable timer 12. Application information RC oscillator timing component limitations The oscillator frequency is mainly determined by R C , provided R << R and TC TC TC S R C <<R C . The function of R is to minimize the influence of the forward voltage S 2 TC TC S across the input protection diodes on the frequency. The stray capacitance C should be 2 kept as small as possible. In consideration of accuracy, C must be larger than the TC inherent stray capacitance. R must be larger than the LOCMOS ‘ON’ resistance in TC series with it, which typically is 500  at V = 5 V, 300  at V = 10 V and 200  at DD DD V =15V. DD The recommended values for these components to maintain agreement with the typical oscillation formula are: C  100 pF, up to any typical value, 10 k  R  1 M.
