Микросхема CD4047BE, Моностабильный/ нестабильный мультивибратор, [DIP-14]

Характеристики

CD4047BE, Моностабильный/ нестабильный мультивибратор, [DIP-14]The CD4047BE is a CMOS low-power Mono-stable/Astable Multi-vibrator 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 and 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 off 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 gatable multivibrator.

• Lower power consumption special CMOS oscillator configuration
• Monostable (one-shot) or astable (free-running) operation
• True and complemented buffered outputs
• Only one external R and C required
• Buffered inputs
• 100% Tested for quiescent current at 20V
• Standardized, symmetrical output characteristics
• Positive-or negative-edge trigger
• Output pulse width independent of trigger pulse duration
• Retriggerable option for pulse width expansion
• Internal power-on reset circuit
• Long pulse widths possible using small RC components by means of external counter provision
• Fast recovery time essentially independent of pulse width
• Pulse-width accuracy maintained at duty cycles approaching 100%
