NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
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.
