The 74HC125 is a quad buffer with 3-state outputs. Below are its specifications:

• Supply Voltage (Vcc): 2V to 6V
• Input Low/High Voltage: Vcc x 0.3 (max) / Vcc x 0.7 (min)
• Output Current: ±6mA at 5V
• Propagation Delay: ~14ns at 5V
• Operating Temperature: -40°C to +125°C
• Features:
  • High-speed CMOS logic
  • Independent 3-state output control for each buffer
  • Low power consumption

It is commonly used for signal buffering and bus driving applications. Always check the datasheet for detailed specs.
