• Manufacturer Part Number: 74lvt244b
• Description: 3.3v Octal Buffer/line Driver 3-state
• Manufacturer: NXP Semiconductors

1. All typical values are at T
2. This is the increase in supply current for each input at the specified voltage level other than V
3. This parameter is valid for any V
4. Unused pins at V
5. I
6. This is the bus hold overdrive current required to force the input to the opposite logic state.
