CD4047 - Astable/Monostable Multivibrator IC
CD4047 - Astable/Monostable Multivibrator IC CD4047 IC consists of a gateable 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 an OSCILLATOR. In all modes of operation, an external capacitor must be connected between C-Timing and RC-Common terminal, and an external resistor must be connected between the R-Timing and RC-Common terminals. Astable operation is enabled by a high level on the STABLE input or a low level on the ASTABLE\ input, or both. The period of the square wave at the Q and Q\ Outputs in this mode of operation is a function of the external components employed. "True" input pulses on the ASTABLE input or "Complement" pulses on the ASTABLE\ input allow the circuit to be used as a gateable multivibrator. The OSCILLATOR output period will be half of the Q terminal output in the astable mode. However, a 50% duty cycle is not guaranteed at this output. The CD4047 triggers in the monostable mode when a positive-going edge occurs on the +TRIGGER-input while the -TRIGGER is held low. Input pulses may be of any duration relative to the output pulse. The CD4047-Series types are supplied in 14-lead hermetic dual-in-line ceramic packages (F3A suffix), 14-lead dual-in-line plastic packages (E suffix), 14-lead small-outline packages (M, MT, M96, and NSR suffixes), and 14-lead thin shrink small-outline packages (PW and PWR suffixes). check out : CD4094 - 8-Stage Shift and Store Bus Register IC Pinout: Pinout of CD4047 IC Applications: Digital equipment where low-power dissipation and/or high noise immunity are primary design requirements: Envelope detection Frequency multiplication Frequency division Frequency discriminators Timing circuits Time-delay applications Package Includes: Selected qty of IC - CD4047 Specifications: Part number CD4047B Technology Family CD4000 VCC (Min) (V) 3 VCC (Max) (V) 18 Channels (#) 1 ICC @ nom voltage (Max)(mA) 600 IOL (Max) (mA) 4 IOH (Max) (mA) -4 Rating See Data Sheet Input Type Standard CMOS Output Type Push-Pull Features Balanced
