TWO-LINE OUTPUT CONTROL FUNCTION
To accommodate multiple memory connections, a two-
line control function is provided to allow for:
It is recommended that CE be decoded and used as
the primary device-selecting function, while OE be made
a common connection to all devices in the array and
connected to the READ line from the system control
bus. This assures that all deselected memory devices
are in their low-power standby mode and that the output
pins are only active when data is desired from a particular
memory device.
NOTES:
1. VH = 12.0 V ± 0.5 V
2. X = Either VIH or VIL
3. A1 - A8 = A10 - A16 = VIL(For auto select)
4. See DC Programming Characteristics for VPP voltage during programming.
MODE SELECT TABLE
1. Low memory power dissipation,
2. Assurance that output bus contention will not
occur.

SYSTEM CONSIDERATIONS
During the switch between active and standby
conditions, transient current peaks are produced on the
rising and falling edges of Chip Enable. The magnitude
of these transient current peaks is dependent on the
output capacitance loading of the device. At a minimum,
a 0.1 uF ceramic capacitor (high frequency, low inherent
inductance) should be used on each device between
Vcc and GND to minimize transient effects. In addition,
to overcome the voltage drop caused by the inductive
effects of the printed circuit board traces on EPROM
arrays, a 4.7 uF bulk electrolytic capacitor should be
used between Vcc and GND for each eight devices. The
location of the capacitor should be close to where the
power supply is connected to the array.
