2. Voltage Range: This device operates within a supply voltage range of 2.0V to 5.5V, making it suitable for low-voltage applications. It is compatible with both TTL and CMOS logic levels.

3. Propagation Delay: The SN74LV123ARGYR boasts a fast propagation delay, typically around 25 ns at 5V, which allows for quick response times in timing applications.

4. Output Drive Capability: The output can drive up to 24 mA, making it capable of interfacing with various loads without the need for additional buffering.

5. Temperature Range: The device is rated for operation over a temperature range of -40°C to +125°C, ensuring reliability in harsh environments.

6. Pin Configuration: The SN74LV123ARGYR is available in a 14-pin TSSOP (Thin Shrink Small Outline Package) form factor, which is compact and suitable for space-constrained applications. The pins are arranged to facilitate easy integration into circuit boards.

7. Applications: Common applications include pulse width modulation, timer circuits, frequency dividers, and other timing-related functions in digital systems.

8. Logic Levels: The device features standard logic levels, ensuring compatibility with other digital components in a system.

Electrical Characteristics:

• Input High Voltage (VIH): Minimum of 2.0V for a 5V supply.
• Input Low Voltage (VIL): Maximum of 0.8V for a 5V supply.
• Output High Voltage (VOH): Typically close to the supply voltage when driving a load.
• Output Low Voltage (VOL): Typically low when the output is in the low state.

Packaging and Ordering Information:

The SN74LV123ARGYR is typically supplied in tape and reel packaging for automated assembly processes. The part number includes the suffix "ARGYR," indicating the specific package type and temperature range.

Conclusion:
