5 / 21 page 5 IDT7007S/L High-Speed 32K x 8 Dual-Port Static RAM Military, Industrial and Commercial Temperature Ranges Truth Table I: Non-Contention Read/Write Control Truth Table II: Semaphore Read/Write Control(1) Absolute Maximum Ratings(1) Recommended Operating Conditions Maximum Operating Temperature and Supply Voltage(1,2) Capacitance (TA = +25°C, f = 1.0mhz) NOTE: 1. A0L A14L ≠ A0R A14R NOTE: 1. There are eight semaphore flags written to via I/O0 and read from all I/O's. These eight semaphores are addressed by A0 - A2. 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 sec-tions of this specification is not implied. Exposure to absolute maxi-mum 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 < 20mA for the period of VTERM > Vcc + 10%. NOTES: 1. This is the parameter TA. 2. Industrial temperature: for other speeds, packages and powers contact your sales office. 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. TQFP package only. 2. 3dV represents the interpolated capacitance when the input and output signals switch from 0V to 3V or from 3V to 0V.
