Description

The P93U422 is a 1,024-bit high-speed Static RAM with a 256 x 4 organization. The P93U422 is a universal device designed to replace the entire 93 and 93L 256 x 4 static RAM families. The memory requires no clocks or refreshing and has equal access and cycle times. Inputs and outputs are fully TTL compatible. Operation is from a single 5 Volt supply. Easy memory expansion is provided by an active LOW chip select one (CS1) and active HIGH chip select two (CS2) as well as 3-state outputs.

In addition to high performance, P93U422 features latchup protection, single event and upset protection. The P93U422 is offered in several packages: 22-pin 400 mil DIP (plastic and ceramic), 24-pin 300 mil SOIC, 24-pin square LCC and 24-pin CERPACK. Devices are offered in both commercial and military temperature ranges.
