DESCRIPTION
The P4C423 is a 1,024-bit high-speed (10ns) Static RAM with a 256 x 4 organization. The memory requires no clocks or refreshing and has equal access and cycle times. Inputs and outputs are fully TTL patible. 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 and high density, the device features latch-up protection, single event and upset protection. The P4C423 is offered in a 24-pin 300 mil DIP. Devices are offered in both mercial and military temperature ranges.
