74HC123D - Dual Monostable Multivibrator

General Description

2.

The 74HC123D is a high speed CMOS MONOSTABLE MULTIVIBRATOR fabricated with silicon gate C2MOS technology.

It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.

Key Features

  • (Note) (1) Wide operating temperature range: Topr = -40 to 125.
  • (Note 1) (2) High speed: tpd = 25 ns (typ. ) at VCC = 5 V (3) Low power dissipation: Standby state: ICC = 4.0 µA (max) at Ta = 25.
  • Active state: ICC = 1000 µA (max) at Ta = 25.
  • (4) Balanced propagation delays: tPLH ≈ tPHL (5) Wide operating voltage range: VCC(opr) = 2.0 to 6.0 V Note: In the case of using only one circuit, CLR should be tied to GND, RX/CX.
  • CX.
  • Q.
  • Q should be tied to OPEN, the other inputs shou.

CMOS Digital Integrated Circuits Silicon Monolithic 74HC123D 74HC123D 1. Functional Description • Dual Monostable Multivibrator 2. General The 74HC123D is a high speed CMOS MONOSTABLE MULTIVIBRATOR fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. 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).
