DESCRIPTION

· The SN74ALVC7804 is an 18-bit FIFO memory designed for high-speed data processing with fast access times.
· It operates at a voltage range of 3-V to 3.6-V VCC.
· 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 memory can handle data rates up to 40 MHz with access times of 18 ns.
· It includes full, empty, half-full, and programmable almost-full/almost-empty flags to monitor the status of the memory.
· The FIFO must be reset upon power up, and the first word loaded into empty memory causes the EMPTY flag to go high and the data to appear on the Q outputs.

FEATURES

· Operates at 3-V to 3.6-V VCC.
· Load Clock and Unload Clock can be asynchronous or coincident.
· Utilizes low-power advanced CMOS technology.
· Includes full, empty, half-full, and programmable almost-full/almost-empty flags.
· Fast access times of 18 ns with a 50-pF load and all data outputs switching simultaneously.
· Supports data rates from 0 to 40 MHz.
· Features 3-state outputs.
· Pin compatible with SN74ACT7804.
· Packaged in a Shrink Small-Outline 300-mil package (DL) using 25-mil center-to-center spacing.

APPLICATIONS

· Suitable for high-speed data buffering and storage applications.
· Ideal for systems requiring independent data write and read rates.
· Used in applications where monitoring of memory status (full, empty, half-full, almost-full/almost-empty) is crucial.
· Applicable in systems operating at 3-V to 3.6-V VCC.
· Can be used in environments requiring low-power advanced CMOS technology.
