Two Line Output Control
BecauseEPROMsareusuallyusedinlargermem-
ory arrays, this product features a 2 line control
functionwhich accommodatesthe use of multiple
memory connection. The two line control function
allows:
a. the lowestpossiblememory power dissipation,
b. completeassurancethat output bus contention
will not occur.
Forthemostefficientuse of thesetwocontrollines,
E should be decoded and used as the primary
deviceselectingfunction,while G shouldbe made
a common connection to all devices in the array
and connected to the READ line from the system
controlbus.Thisensuresthat all deselectedmem-
ory devices are in their low power standby mode
and that the output pins are only active when data
is requiredfrom a particularmemory device.
SystemConsiderations
The power switching characteristics of Advanced
CMOSEPROMs require careful decouplingof the
devices. The supply current, I
CC
, has three seg-
ments that are of interestto the system designer :
the standby current level, the active current level,
and transient current peaks that are produced by
thefalling and rising edgesof E. Themagnitudeof
transientcurrentpeaksisdependentonthecapaci-
tive and inductive loading of the device at the
output.
