Overview
1CY 7C40 2 CY7C401/CY7C403 CY7C402/CY7C404 64 x 4 Cascadable FIFO 64 x 5 Cascadable FIFO Features • 64 x 4 (CY7C401 and CY7C403) 64 x 5 (CY7C402 and CY7C404) High-speed first-in first-out memory (FIFO) • Processed with high-speed CMOS for optimum speed/power • 25-MHz data rates • 50-ns bubble-through time—25 MHz • Expandable in word width and/or length • 5-volt power supply ± 10% tolerance, both commercial and military • Independent asynchronous inputs and outputs • TTL-compatible interface • Output enable function available on CY7C403 and CY7C404 • Capable of withstanding greater than 2001V electrostatic discharge • Pin compatible with MMI 67401A/67402A words.
Both the CY7C403 and CY7C404 have an output enable (OE) function.
The devices accept 4- or 5-bit words at the data input (DI0 – DIn) under the control of the shift in (SI) input.
The stored words stack up at the output (DO0 – DOn) in the order they were entered.
A read command on the shift out (SO) input causes the next to las...
