2 / 18 page Symbol Parameter Value Unit TA Ambient Operating Temperature –40 to 125 °C TSTG Storage Temperature –65 to 150 °C TLEAD Lead Temperature, Soldering (SO8 package) (PSDIP8 package) 40 sec 10 sec 215 260 °C VO Output Voltage –0.3 to VCC +0.6 V VI Input Voltage with respect to Ground –0.3 to 6.5 V VCC Supply Voltage –0.3 to 6.5 V VESD Electrostatic Discharge Voltage (Human Body model) (2) 4000 V Electrostatic Discharge Voltage (Machine model) (3) 500 V Notes: 1. Except for the rating ”Operating Temperature Range”, stresses above those listed in the Table ”Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other conditions above those indicated in the Operating sections of this specification is not i mplied. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability. Refer also to the STMicroelectronics SURE Program and other relevant quality documents. 2. MIL-STD-883C, 3015.7 (100pF, 1500 Ω) 3. EIAJ IC-121 (Condition C) (200pF, 0 Ω) Table 2. Absolute Maximum Ratings (1) The device connected to the bus is selected when the chip select input (S) goes low. Communications with the chip can be interrupted with a hold input (HOLD). The write operation is disabled by a write protect input (W). Data is clocked in during the low to high transition of clock C, data is clocked out during the high to low transition of clock C. SIGNALS DESCRIPTION Serial Output (Q). The output pin is used to trans- fer data serially out of the Memory. Data is shifted out on the falling edge of the serial clock. Serial Input (D). The input pin is used to transfer data serially into the device. It receivesinstructions, addresses, and the data to be written. Input is latched on the rising edge of the serial clock.
