4. Absolute maximum ratings*
Note: 1. Minimum voltage is -0.6V DC, which may undershoot to -2.0V for pulses of less than 20ns. Maximum output pin voltage is
VCC + 0.75V DC, which may overshoot to +7.0V for pulses of less than 20ns.
5. DC and AC characteristics
Table 5-1. Operating modes
Note: 1. X can be VIL or VIH.
2. Refer to programming characteristics.
3. VH = 12.0 ± 0.5V.
4. Two identifier bytes may be selected. All Ai inputs are held low (VIL), except A9, which is set to VH, and A0, which is toggled low
(VIL) to select the manufacturer’s identification byte and high (VIH) to select the device code byte.
