FUNCTIONAL DESCRIPTION
The Synergy SY10/100/101474 are 4096-bit RAMs
organized as 1024-words-by-4-bits. Memory cell selection
is achieved by using the 10 address bits designated as A0
through A9.
Each of the 210 possible input address
combinations corresponds to a unique word location in
memory. The active low Chip Select (CS) is provided for
memory expansion.
The active low Write Enable (WE)
controls the read and write operation. Data resident on the
DIN inputs (DI0 through DI3) is written into the addressed
location only when WE and CS are held low. In order to
perform a read operation, WE is held high, CS is held low
and the non-inverted output data at the addressed location
is transferred to DOUT (DO0 through DO3) to be read out.
Open emitter outputs are provided for maximum flexibility
and memory expansion by allowing output wire-OR
connections. External termination of 50
Ω to –2.0V or an
equivalent circuit must be used to provide the specified
output levels.
The outputs are brought to a logical low level when the
RAM is being written into (WE = LOW) or when the device
is deselected via the active low chip select pin (CS = HIGH).

implied at conditions other than those detailed in the operational sections
of this data sheet. Exposure to ABSOLUTE MAXIMUM RATlNG conditions
for extended periods may affect device reliability.
