Actel User Notes
HX6256_ttl_notice
The 256K SRAM in the 28 lead flat pack does not provide a satisfactory ground connection for operation in TTL mode for the Read conditions listed in datasheet HX6256. Toggling the NOE pin coincident with an address change could cause the chip to enter oscillation if all of the inputs are toggled together.
