Product Introduction

Overview

The 74HC123D,652, produced by Nexperia USA Inc., is a dual retriggerable monostable multivibrator with reset. This integrated circuit is part of the 74HC series and is designed to provide flexible timing and pulse generation capabilities. The device features two independent monostable multivibrators, each capable of generating a pulse width that can be programmed using external resistors and capacitors. The multivibrators can be triggered by either rising or falling edges on the input signals and can be reset at any time by a LOW-going edge on the reset input.

Key Features

  • Dual retriggerable monostable multivibrator with reset, allowing for flexible pulse width programming and extension.
  • Schmitt-trigger action on inputs (nA and nB) for high noise immunity and tolerance to slower input rise and fall times.
  • Wide supply voltage range from 2.0 V to 6.0 V, making it suitable for various applications.
  • CMOS low power dissipation, reducing energy consumption.
  • Latch-up performance exceeds 100 mA per JESD 78 Class II Level B, ensuring robust operation.
  • Inputs include clamp diodes, enabling the use of current limiting resistors to interface inputs to voltages in excess of VCC.
  • Complies with JEDEC standards for input levels (CMOS level for 74HC123 and TTL level for 74HCT123).

Applications

The 74HC123D,652 is versatile and can be used in a variety of applications across different industries, including:

  • Automotive systems: For timing and pulse generation in automotive electronics.
  • Industrial control systems: To provide timing signals and pulse widths in industrial automation.
  • Consumer electronics: In devices requiring precise timing and pulse generation, such as audio equipment and consumer appliances.
  • Computing and networking: For clocking and timing in computer peripherals and network devices.
  • Medical devices: Where precise timing and pulse generation are critical.
