DESCRIPTION

· The SN74ACT7806 is a 256-word by 18-bit FIFO memory designed for high-speed data processing with fast access times.

· It operates at data rates up to 50 MHz and offers access times of 15 ns in a bit-parallel format.

· Data is written into memory on the low-to-high transition of the load clock (LDCK) and read out on the low-to-high transition of the unload clock (UNCK).

· The FIFO status is monitored by full (FULL), empty (EMPTY), half-full (HF), and programmable almost-full/almost-empty (AF/AE) flags.

FEATURES

· 256 words by 18 bits FIFO memory.

· Low-power Advanced CMOS technology.

· Fast access times of 15 ns with a 50-pF load.

· Data rates up to 50 MHz.

· 3-State outputs.

· Pin-to-pin compatible with SN74ACT7804 and SN74ACT7814.

· Packaged in a shrink small-outline 300-mil package using 25-mil center-to-center spacing.

APPLICATIONS

· High-speed data buffering.

· Data rate matching in communication systems.

· Temporary storage in data processing systems.

· Interface between systems with different data rates.
