TC7WH123FK - Monostable Multivibrator

Download the TC7WH123FK datasheet PDF. This datasheet also covers the TC7WH123FU variant, as both devices belong to the same monostable multivibrator family and are provided as variant models within a single manufacturer datasheet.

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.
