The 72V82 is a dual-FIFO memory that loads and empties data on a first-in/first-out basis. It utilizes a 9-bit wide data array to allow for control and parity bits at the user's option. This is useful in data communications applications where a parity bit is needed for transmission/reception error checking. It is designed for those applications requiring asynchronous and simultaneous read/writes in multiprocessing and rate buffer applications.

The 72V845 is a 4K x 18 dual sync FIFO with clocked read and write controls that is functionally equivalent to two 72V245 FIFO's in a single package with all associated control, data, and flag lines assigned to independent pins. This FIFO is useful for optical disk controllers, Local Area Networks (LANs), and interprocessor communication. Each of the two FIFOs has an 18-bit input and output port. The Read Clock can be tied to the Write Clock for single clock operation or the two clocks can run asynchronous of one another for dual-clock operation.

The 72V851 is an 8K x 9 dual synchronous FIFO that is functionally equivalent to two 72V251 FIFOs in a single package with all associated control, data, and flag lines assigned to separate pins. Each FIFO has a 9-bit input and output data port. The Read Clock can be tied to the Write Clock for single clock operation or the two clocks can run asynchronously of one another for dual clock operation.
