HEF4047B-Q100 Monostable/astable multivibrator Rev. 1 17 March 2017 Product data sheet 1 General description The HEF4047B-Q100 is a retriggerable astable multivibrator that can be configured as either a positive-edge or negative-edge triggered monostable multivibrator. The output pulse width is programmed by selection of external components (R and C ). Inputs t t include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of V . CC This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 3) and is suitable for use in automotive applications. 2 Features and benefits 2.1 General Automotive product qualification in accordance with AEC-Q100 (Grade 3) Specified from -40 C to +85 C Monostable (one-shot) or astable (free-running) operation True and complemented buffered outputs Only one external resistor and capacitor required ESD protection: MIL-STD-883, method 3015 exceeds 2000 V HBM JESD22-A114F exceeds 2000 V MM JESD22-A115-A exceeds 200 V (C = 200 pF, R = 0 ) 2.2 Monostable multivibrator Positive- or negative-edge triggering Output pulse width independent of trigger pulse duration Retriggerable option for pulse-width expansion Long pulse width possible using small RC components with external counter provision Fast recovery time independent of pulse width Pulse-width accuracy maintained at duty cycles approaching 100% 2.3 Astable multivibrator Free-running or gatable operating modes 50% duty cycle Oscillator output availableNexperia HEF4047B-Q100 Monostable/astable multivibrator 3 Ordering information Table 1.
