7440105 FIFO REGISTER IC 16-DIP
The 7440105 IC FIFO REGISTER 16-DIP is a 4-bit × 16-word First-In, First-Out (FIFO) storage register designed to temporarily store and transfer digital data in sequential order. The device can store 16 words of 4 bits each, providing a total storage capacity of 64bits. It is particularly useful for buffering data between digital systems operating at different data-transfer rates.
Features:
- 4-bit × 16-word FIFO storage architecture.
- 64-bit total storage capacity.
- Independent asynchronous data input and output operation.
- Four parallel data inputs.
- Four parallel three-state data outputs.
- Data-In Ready and Data-Out Ready status indicators.
