TC74VHC221AFN - DUAL MONOSTABLE MULTIVIBRATOR

General Description

(1) Standby state The external capacitor (CX) is fully charged to VCC in the stand-by state.

triggering, the QP and QN transistors which are connected to the RX/CX node are in the off state.

Key Features

  • High speed: tpd = 8.1 ns (typ. ) at VCC = 5 V.
  • Low power dissipation Standby state: 4 μA (max) at Ta = 25°C Active state: 600 μA (max) at Ta = 25°C.
  • High noise immunity: VNIH = VNIL = 28% VCC (min).
  • Power down protection is equipped with all inputs.
  • Balanced propagation delays: tpLH ∼.
  • tpHL.
  • Wide operating voltage range: VCC (opr) = 2 to 5.5 V.
  • Pin and function compatible with 74HC123A/221A TC74VHC123AFN, TC74VHC221AFN TC7.

TC74VHC123AF, TC74VHC221AF The TC74VHC123A/221A are high speed CMOS MONOSTABLE MULTIVIBRATOR fabricated with silicon gate C2MOS technology. There are two trigger inputs, A input (negative edge), and B input (positive edge). These inputs are valid for a slow rise/fall time signal (tr = tf = 1 s) as they are schmitt trigger inputs. This device may also be triggered by using CLR input (positive edge).
