Notes:
2. Minimum DC input is –0.3V. During transitions, the inputs may undershoot to –2.0V for periods less than 20 ns.
3. Typical values are for T_A = 25°C and V_CC = 5V.
4. Guaranteed by design but not 100% tested.
5. Not more than one output should be tested at a time. Duration of the short circuit should not be more than one second. V_OUT = 0.5V has been chosen to avoid
test problems caused by tester ground degradation.
6. Measured with device programmed as a 16-bit counter.
7. Part (a) in AC Test Load and Waveforms is used for all parameters except t_ER and t_XZ, 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.
