TC74HC423AP Dual Retriggerable Monostable Multivibrator

(1) Stand-by state The external capacitor Cx is fully charged to VCC in the stand-by state. That means, before triggering, the QP and QN transistors which are connected to the Rx/Cx node are in the off state. Two comparators that relate to the timing of the output pulse, and two reference voltage supplies turn off. The total supply current is only leakage cu.

Features

(Note)
• High speed: tpd = 25 ns (typ.) at VCC = 5 V
• Low power dissipation Standby state: ICC = 4 μA (max) at Ta = 25°C Active state: ICC = 700 μA (max) at VCC = 5 V
• High noise immunity: VNIH = VNIL = 28% VCC (min)
• Output drive capability: 10 LSTTL loads
• Symmetrical output impedance: |IOH| = IOL = 4 mA (min)
• Balanced propagation delays: tpLH ∼− tpHL
• Wide operating voltage range: VCC (opr) = 2 to 6 V
• Pin and function compatible with 74LS423 Weight DIP16-P-300-2.54A SOP16-P-300-1.27A : 1.00 g (typ.) : 0.18 g (typ.) Note: In the case of using only one circuit, CLR should be tied .
