7489 64 Bit Random Access Memory RAM DIP-16

Product details of 7489 64 Bit Random Access Memory RAM DIP-16
The 7489 is a high speed 64 bit RAM organized as 16-word by 4-bit array. Address inputs are buffered to minimize loading, and addresses are fully decoded inside the chip. Outputs are open collector type allowing the chip to be multiplexed with many others. When the chip is deselected the outputs go into high impedance mode allowing other chips, wired in parallel, to perform with no interference.
