4 / 19 page  IDT7034S/L High-Speed 4K x 18 Dual-Port Static RAM Industrial and Commercial Temperature Ranges 4 Recommended DC Operating Conditions Maximum Operating Temperature and Supply Voltage(1) Capacitance (TA = +25°C, f = 1.0MHz)(1) Absolute Maximum Ratings(1) NOTE: 1. There are eight semaphore flags written to via I/O0 and read from I/O0 - I/O17. These eight semaphores are addressed by A0 - A2. Truth Table II: Semaphore Read/Write Control(1) (1) (1) (1) (1) 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. 2. VTERM must not exceed Vcc + 10% for more than 25% of the cycle time or 10ns maximum, and is limited to < 20 mA for the period over VTERM > Vcc + 10%. NOTES: 1. This is the parameter TA. This is the "instant on" case temperature. NOTES: 1. VIL > -1.5V for pulse width less than 10ns. 2. VTERM must not exceed Vcc + 10%. NOTES: 1. This parameter is determined by device characterization but is not production tested. 2. 3dV references the interpolated capacitance when the input and output signals switch from 0V to 3V or from 3V to 0V.
