TIMING WAVEFORM OF READ CYCLE

Notes:

1. Stresses greater than those listed under MAXIMUM RATINGS may

cause permanent damage to the device. This is a stress rating only

and functional operation of the device at these or any other conditions

above those indicated in the operational sections of this specification

is not implied. Exposure to MAXIMUM rating conditions for extended

periods may affect reliability.

2. Extended temperature operation guaranteed with 400 linear feet per

minute of air flow.

3. Transient inputs with V

IL and IIL not more negative than –3.0V and

–100mA, respectively, are permissible for pulse widths up to 20 ns.

4. This parameter is sampled and not 100% tested.
