TC7WH123FU - Monostable Multivibrator

General Description

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

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: ICC = 2 μA (max) at Ta = 25°C.
  • Active state : ICC = 650 μA (max) at VCC = 4.5 V.
  • 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 Start of commercial production 1998-08 1 20.

TC7WH123FU/FK TOSHIBA CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC TC7WH123FU, TC7WH123FK Monostable Multivibrator The TC7WH123 is 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). After triggering, the output stays in a MONOSTABLE state for a time period determined by the external resistor and capacitor (RX, CX). A low level at the CLR input breaks this state. Limits for CX and RX are: External capacitor, CX: No limit External resistor, RX: VCC = 2.0 V more than 5 kΩ VCC ≥ 3.
