CD4047BMS
December 1992
CMOS Low-Power Monostable/Astable Multivibrator
Description
CD4047BMS consists of a gatable astable multivibrator with logic techniques incorporated to permit positive or negative edge triggered monostable multivibrator action with retriggering and external counting options. Inputs include +TRIGGER, -TRIGGER, ASTABLE, ASTABLE, RETRIGGER, and EXTERNAL RESET. Buffered outputs are Q, Q, and OSCILLATOR. In all modes of operation, an external capacitor must be connected between C-Timing and RC-Common terminals, and an external resistor must be connected between the R-Timing and RCCommon terminals. Astable operation is enabled by a high level on the ASTABLE input or a low level on the ASTABLE input, or both.
