HEF4541BT规格书详情
1. General description
The HEF4541B 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 RTC and CTC determines 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, 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 VDD power supply range of 3 V to 15 V referenced to VSS (usually
ground). Unused inputs must be connected to VDD, VSS, or another input.
