• Manufacturer Part Number: 74abth16821adl
• Description: 20-bit Bus-interface D-type Flip-flop; Positive-edge Trigger 3-state
• Manufacturer: NXP Semiconductors

3. For valid test results, data must not be loaded into the flip-flops (or latches) after applying the power.
4. This parameter is valid for any V
5. This is the bus hold overdrive current required to force the input to the opposite logic state.

DC ELECTRICAL CHARACTERISTICS
NOTES:
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.
