Functional Features

The MM74HC123AMTCX is a high-speed monostable multivibrator integrated circuit. It is designed to generate a single pulse of a fixed duration in response to an external trigger signal. The key features of this IC include:

• Flip-Flop with Clear and Complementary Outputs
• Wide Supply Voltage Range (2V to 6V)
• Short Propagation Delay Time (14 ns typical)
• High Output Current Capability (±25 mA)
• Low Input Capacitance (3.5 pF typical)

Advantages and Disadvantages

Advantages: - High-speed operation - Flexible control voltage input - Compact TSSOP-16 package - Reliable performance over a wide temperature range

Disadvantages: - Limited supply voltage range (2V to 6V) - Relatively low output current capability

Working Principles

The MM74HC123AMTCX operates as a monostable multivibrator, which means it can be triggered by an external signal to produce a single pulse of a fixed duration. The triggering can be controlled using the Trigger (TR) and Control Voltage (CV) inputs. When the trigger input goes from high to low, the output Q changes state and remains in that state for a time determined by the external timing components connected to the threshold (TH) and control voltage (CV) inputs.
