The MCM is input and output TTL compatible. Writing is executed when the write enable (WE) and chip enable (CE) inputs are low and output enable (OE) is high. Reading is accomplished when WE is high and CE and OE are both low. Access time grades of 17ns, 20ns, 25ns, 35ns, 45ns and 55ns maximum are standard. The +5 Volt power supply version is standard and +3.3 Volt lower power model is a future optional product. The products are designed for operation over the temperature range of -55C to +125C and under the full military environment. A DESC Standard Military Drawing (SMD) number is released. The ACT-S512K8 is manufactured in Aeroflex's 80,000 square foot MIL-PRF-38534 certified facility in Plainview, N.Y. eroflex Circuit Technology - Advanced Multichip Modules (c) SCD1664 REV C 5/10/00 Absolute Maximum Ratings Symbol TC TSTG Parameter MINIMUM MAXIMUM Units Case Operating Temp. -55 +125 C Storage Temperature -65 +150 C - 1.1 W PD Maximum Package Power Dissipation VG Maximum Signal Voltage to Ground -0.5 VCC + 0.5 V VCC Power Supply Voltage -0.5 +7.0 V TJ Junction Temperature - +150 C Recommended Operating Conditions Symbol Parameter Minimum Maximum Units VCC Power Supply Voltage +4.5 +5.5 V VIH Input High Voltage +2.2 VCC + 0.3 V VIL Input Low Voltage -0.5 +0.8 V TA Operating Temp.
