Analog Devices Inc. DS22B57 is a standard 32K x 8 asynchronous CMOS SRAM with a maximum access time of 150ns. This component features a 262,144-bit memory density and operates with a supply voltage range of 3.0V to 3.6V, with operation also possible at 4.5V to 5.5V. The DS22B57 is housed in a 28-lead PDIP package (R-PDIP-T28) and utilizes through-hole mounting. Its output characteristics are 3-state, and it supports common I/O. This SRAM is suitable for applications in industrial controls, consumer electronics, and data acquisition systems where reliable, high-speed memory is required. It maintains a standby current of 1mA maximum and a supply current of 60mA maximum.
