74ABT244 Philips Semiconductors, 74ABT244 Datasheet - Page 4

• Manufacturer Part Number: 74ABT244
• Description: Octal buffer/line driver 3-State
• Manufacturer: Philips Semiconductors

1. Not more than one output should be tested at a time, and the duration of the test should not exceed one second.
2. This is the increase in supply current for each input at 3.4V.
3. This parameter is valid for any V
