DESCRIPTION

· The 74ACT2708 is a 64x9 expandable FIFO memory with dual port RAM architecture and pointer logic for high-speed operations.

· It supports an 85 MHz shift-in and 60 MHz shift-out data rate, making it suitable for high-speed applications.

· The device features separate Shift-In (SI) and Shift-Out (SO) clocks for synchronous or asynchronous write/read operations.

· Includes Master Reset (MR), Output Enable (OE), Input Ready (IR), and Output Ready (OR) controls for initialization and 3-STATE outputs.

· Status flags HF and FULL indicate FIFO status (full, empty, or half full).

FEATURES

· 64-word by 9-bit dual port RAM organization.

· 85 MHz shift-in and 60 MHz shift-out data rates (typical).

· Expandable in word width only.

· TTL-compatible inputs and 3-STATE outputs.

· Asynchronous or synchronous operation with asynchronous master reset.

· Outputs source/sink 8 mA with full ESD protection.

· Input and output pins aligned for easy board layout.

· TRW 1030 work-alike operation.

APPLICATIONS

· High-speed disk or tape controllers.

· A/D output buffers.

· High-speed graphics pixel buffers.

· Video time base correction.

· Digital filtering.
