Datasheet: (PDF)
Main Features:
- Lower power consumption: special CMOS oscillator configuration
- Monostable (one-shot) or astable (free-running) operation
- True and complemented buffered outputs
- Only one external R anc C required
- Buffered inputs
- 100% tested for quiescent current at 20 V
- Standardized, symmetrical output characteristics
- 5-V, 10-V, and 15-V parametric ratings
- Meets all requirements of JEDEC Tentative Standard No. 13B, "Standard Specifications for Description of 'B' Series CMOS Devices"
Monostable Multi vibrator Features:
- Positive-or negative-edge trigger
- Output pulse width independent of trigger pulse duration
- Re-triggerable 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%
As table Multi vibrator Features:
- Free-running or gatable operating modes
- 50% duty cycle
- Oscillator output available
- Good astable frequency stability:
Frequency deviation:
- = ±2% + 0.03%/°C @ 100 kHz
- = ±0.5% +0.015%/°C @ 10 kHz (circuits "trimmed" to frequency VDD = 10 V ± 10%)
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
