The MCM can be organized as a 128K x 32 bits, 256K x 16 bits or 512k x 8 bits device and is input and output TTL compatible. Writing is executed when the write enable (WE) and chip enable (CE) inputs are low. Reading is accomplished when WE is high and CE and output enable (OE) are both low. Access time grades of 35ns and 45ns maximum are standard. The +5 Volt power supply version is standard. The products are designed for operation over the temperature range of -55°C to +125°C and screened under the full military environment. DESC Standard Military Drawing (SMD) part numbers are pending. The ACT-RS128K32 is manufactured in Aeroflex’s 80,000ft2 MIL-PRF-38534 certified facility in Plainview, N.Y.
