When two or more ’29F008T/B devices are connected in parallel, the output of any one device can be read without interference. The CE pin is for power control and must be used for device selection. The OE pin is for output control, used to gate the data output onto the bus from the selected device. The address-access time (tAVQV) is the delay from stable address to valid output data. The chip-enable (CE) access time (tELQV) is the delay from CE low and stable addresses to valid output data. The output-enable access time (tGLQV) is the delay from OE low to valid output data when CE equals logic low and addresses are stable for at least the duration of tAVQV–tGLQV. standby mode ICC supply current is reduced by applying a logic-high level on CE and RESET to enter the standby mode. In the standby mode, the outputs are placed in the high-impedance state. Applying a CMOS logic-high level on CE and RESET reduces the current to 100 µA. Applying a TTL logic-high level on CE and RESET reduces the current to 1 mA. If the ’29F008T/B is deselected during erasure or programming, the device continues to draw active current until the operation is complete. output disable When OE equals VIH or CE equals VIH, output from the device is disabled and the output pins (DQ0–DQ7) are placed in the high-impedance state. |
