Advanced Micro Devices' AM2148-70-BUC is a 4Kb asynchronous standard SRAM device organized as 1K words by 4 bits. This NMOS technology component features a maximum access time of 70ns, suitable for applications requiring rapid data retrieval. The device operates with a supply voltage range of 4.5V to 5.5V nominal 5V and offers an automatic power-down function to minimize standby current consumption. Its 18-terminal Ceramic Quad Flatpack (CQCC) package, specified by JESD-30 code R-CQCC-N18, is designed for surface mounting with a terminal pitch of 1.270mm and a seated height of 2.540mm. The AM2148 series is commonly found in industrial and military systems where robust performance and extended operating temperature range (-55°C to 125°C) are critical. Its 3-state outputs facilitate bus-oriented operations.
