HD74LV221A Dual Monostable Multivibrators ADE-205-271A (Z) 2nd Edition June 1999 Description The HD74LV221A features output pulse-duration control by three methods. In the first method, the A input is low and the B input goes high. In the second method, the B input is high and the A input goes low. In the third method, the A input is low, the B input is high, and the clear (CLR) input goes high. The basic pulse duration is programmed by selecting external resistance and capacitance values. The external timing capacitor must be connected between Cext and Rext/Cext (positive) and an external resistor connected between Rext/Cext and VCC. To obtain variable pulse durations, connect an external variable resistance between Rext/Cext and VCC. Pulse duration can be reduced by taking CLR low.

Large values of Cext may cause problems when powering down the HD74LV221A because of the amount of energy stored in the capacitoe. When a system containing diodes at pin 7 or pin15. Current through the input protection diodes must be limited to 10 mA; therefore, the turn-off time of the Vcc power supply must not be faster than t = Vcc • Cext/(20 mA). for example, if Vcc 5 V and Cext = 22 µF, the Vcc supply must turn off no faster than t = (5 V) • (22 µF)/20mA = 5.5 ms. This is usually not a problem because power supplies are heavily filtered and cannot discharge at this rate. When a more rapid decrease of Vcc to zero volts occurs, the HD74LV221A may sustain damage. To avoid this possibility, use an external calmping diode. 10 HD74LV221A • Waveform – 1 Input A tf VCC 90% 50% 10% GND tr VCC 90% 50% Input B 10% GND tf tr 90% 50% Input CLR 10% tr 90% 50% 10% 90% 50% 10% VCC GND t w (L) t PLH (trigger) t PHL VOH Output Q 50% VCC 50% VCC VOL t PHL (trigger) t PLH VOH Output Q 50% VCC 50% VCC VOL 11 HD74LV221A • Waveform – 2 tf tr 90% 50% Input A 10% tr 90% 50% 10% 90% 50% 10% t w (H) tf Input B VCC GND t w (L) tr 90% 50% tf 90% 50% 10% 10% t w (L) VCC 90% 50% 10% t w (H) GND VOH Output Q 50% VCC 50% VCC VOL t w (out) VOH Output Q 50% VCC 50% VCC VOL Note: 1.
