16 x 4 Bit Static Random Access Memory (7489)

Order Code: 38656

SPECIFICATION

Computer Logic Training Board on 16 X 4 Bit Static Random Access Memory (7489) has been designed specifically to get the familiarization of the operation of semiconductor memory. The unit is self contained and provide the understanding of Read, Write and Chip Enable operation with the help of Switches and LEDs. Dynamic operation of the chip can also be understood by connecting the pulse generator at the appropriate terminals. A built in logic indication is also provided on the training board to check the logic state of various pins of the memory chip.
Practical experience on this board carries great educative value for Science and Engineering Students.
