Frequently Asked Questions
What does retriggerable mean for the SN74AHC123APWR?
Retriggerable means that the SN74AHC123APWR can accept a new trigger input before the current output pulse has timed out, causing the output pulse to restart from the beginning. This feature allows the device to maintain a continuous output as long as trigger pulses arrive within the timing interval.
How is the pulse width set on the SN74AHC123APWR?
The output pulse width of the SN74AHC123APWR is set by an external resistor and capacitor connected to the RX and CX pins. The pulse width is approximately 0.45 × R × C, giving designers flexible control over timing from nanoseconds to several seconds depending on component values.
What package and pin pitch does the SN74AHC123APWR use?
The SN74AHC123APWR is available in a 16-pin TSSOP (Small Outline Package) with a 0.65mm terminal pitch and gull-wing leads finished with Ni/Pd/Au, making it compatible with standard surface-mount reflow soldering processes.
What temperature range is the SN74AHC123APWR rated for?
The SN74AHC123APWR is rated for the industrial temperature grade, which typically covers -40°C to +85°C, making it suitable for use in industrial automation, transportation, and test equipment operating in thermally demanding environments.
