This device contains four independent buffer with 3-state outputs and Schmitt-trigger inputs. Each gate performs the Boolean function Y = A in positive logic. The outputs can be put into a Hi-Z state by applying a Low on the OE pin

• Wide operating voltage range: 2 V to 6 V
• Schmitt-trigger inputs allow for slow or noisy input signals
• Low power consumption
  • Typical ICC of 100 nA
  • Typical input leakage current of ±100 nA
• ±7.8-mA output drive at 6 V
• Extended ambient temperature range: 40°C to +125°C, TA
