Absolute Maximum Ratings* Temperature Under Bias................................ -55°C to +125°C *NOTICE: Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent dam- age to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability Storage Temperature ..................................... -65°C to +150°C All Input Voltages (including NC Pins) with Respect to Ground .................................-0.6 V to +6.25 V All Output Voltages with Respect to Ground ...........................-0.6 V to VCC + 0.6 V Voltage on OE and A9 with Respect to Ground ..................................-0.6 V to +13.5V 8.
