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. Once triggered, the basic pulse duration can be extended by retriggering the gated low-level-active ( A) or high-level- active (B) input. Pulse duration can be reduced by taking CLR low. Features • V CC = 2.0 V to 5.5 V operation • All inputs V IH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V) • All outputs V O (Max.) = 5.5 V (@VCC = 0 V) • Output current ±6 mA (@V CC = 3.0 V to 3.6 V), ±12 mA (@VCC = 4.5 V to 5.5 V) • Ordering Information Part Name Package Type Package Code Package Abbreviation Taping Abbreviation (Quantity) HD74LV123AFPEL SOP–16 pin(JEITA) FP–16DAV FP EL (2,000 pcs/reel) HD74LV123ARPEL SOP–16 pin(JEDEC) FP–16DNV RP EL (2,500 pcs/reel) HD74LV123ATELL TSSOP–16 pin TTP–16DAV T ELL (2,000 pcs/reel) Note: Please consult the sales office for the above package availability. |
