1. All testing to be performed using worst-case test conditions unless otherwise specified.
2. The following pins are active low: AVEC, BG, BS, BR, CDIS, CIOUT, IPEND, IPLO, IPL1, IPL2, LOCK, LOCKE, MDIS, MI,
RST0, RSTI, TA, TBI, TCI, TEA, TIP, TRST, TS and W of R/W.
3. Maximum operating junction temperature (TJ) = +125°. Minimum case operating temperature (TC) = -55°. This device is not
tested at TC = +125°. Testing is performed by setting the junction temperature TJ = +125°and allowing the case and ambient
temperatures to rise and fall as necessary so as not to exceed the maximum junction temperature.
4. The levels on CDIS, MDIS, and the IPL2-IPL0 signals enable or disable the multiplexed bus mode, data latch enable mode,
and driver impedance selection respectively.
