TEXAS INSTRUMENTS SN74V3640 SN74V3650 SN74V3660 SN74V3670 SN74V3680 SN74V3690 handbook

The document describes the SN74V3640, SN74V3650, SN74V3660, SN74V3670, SN74V3680, and SN74V3690, which are exceptionally deep, high-speed CMOS first-in first-out (FIFO) memories. These devices feature clocked read and write controls and flexible bus-matching capabilities for x36, x18, or x9 data flow. They are designed for applications requiring large data buffering and bus size matching, such as network, video, and telecommunications systems.

Key features include high-density offerings up to 1 Mbit, 5-V tolerant inputs, and the ability to read and write simultaneously using independent clocks. The FIFOs offer flexible flag options, including empty, full, half-full, and programmable almost-empty/almost-full flags, which can be configured via serial or parallel methods. Timing modes include standard operation and first-word fall-through (FWFT) for depth expansion.
