• Manufacturer Part Number: 74lvt646
• Description: 3.3v Octal Bus Transceiver/register 3-state
• Manufacturer: NXP Semiconductors

1. All typical values are at and 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. For valid test results, data must not be loaded into the flip-flops (or latches) after applying power.
6. This is the bus hold overdrive current required to force the input to the opposite logic state.
