IDT7MB4048
FEATURES:
High-density 4-megabit (512K x 8) Static RAM module Fast access time: 25ns (max.) Surface mounted plastic packages on a 32-pin, 600 mil FR-4 DIP substrate Single 5V (±10%) power supply Inputs/outputs directly TTL-compatible
DESCRIPTION:
The IDT7MB4048 is a 4-megabit (512K x 8) Static RAM module constructed on a multilayer epoxy laminate (FR-4) substrate using four 1 megabit SRAMs and a decoder. The IDT7MB4048 is available with access times as fast as 25ns. The IDT7MB4048 is packaged in a 32-pin FR-4 DIP resulting in the JEDEC footprint in a package 1.6 inches long and 0.6 inches wide. All inputs and outputs of the IDT7MB4048 are TTL-compatible and operate from a single 5V supply. Fully asynchronous circuitry requires no clocks or refresh for operation and provides equal access and cycle times for ease of use.
