AC Test Loads and Waveforms[6]
Notes:
1. Minimum DC input is –0.3V. During transitions, the inputs may undershoot to –3.0V for periods less than 20 ns.
2. Typical values are for TA = 25°C and VCC = 5V.
3. Not more than one output should be tested at a time. Duration of the short circuit should not be more than one second. VOUT = 0.5V has been chosen to avoid
test problems caused by tester ground degradation.
4. Guaranteed by design but not 100% tested.
5. This parameter is measured with device programmed as a 16-bit counter in each LAB.
6. Part (a) in AC Test Load and Waveforms is used for all parameters except tER and tXZ, which is used for part (b) in AC Test Load and Waveforms. All external
timing parameters are measured referenced to external pins of the device.
