VIL > -1.5V for pulse width less than 10ns. 2. VTERM must not exceed Vcc + 0.5V. RECOMMENDED OPERATING TEMPERATURE AND SUPPLY VOLTAGE Ambient Grade Temperature GND VCC Military –55 °C to +125°C 0V 5.0V ± 10% Commercial 0 °C to +70°C 0V 5.0V ± 10% 2954 tbl 05 ABSOLUTE MAXIMUM RATINGS(1) Symbol Rating Commercial Military Unit VTERM (2) Terminal Voltage –0.5 to +7.0 –0.5 to +7.0 V with Respect to GND TA Operating 0 to +70 –55 to +125 °C Temperature TBIAS Temperature –55 to +125 –65 to +135 °C Under Bias TSTG Storage –55 to +125 –65 to +150 °C Temperature IOUT DC Output 50 50 mA Current NOTES: 2954 tbl 04 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 + 0.5V for more than 25% of the cycle time or 10ns maximum, and is limited to < 20mA for the period of VTERM > Vcc + 0.5V. TRUTH TABLE: SEMAPHORE READ/WRITE CONTROL (1) Inputs Outputs CE CE CE CE CE R/ W W W W W OE OE OE OE OE SEM SEM SEM SEM SEM I/O0-8 Mode H H L L DATAOUT Read Semaphore Flag Data Out (I/O0-8) H u X L DATAIN Write I/O0 into Semaphore Flag L X X L — Not Allowed NOTE: 2954 tbl 03 1. There are eight semaphore flags written to via I/O0 and read from I/O0-8 . These eight semaphores are addressed by A0 - A2. NOTES: 1. This parameter is determined by device characteristics 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 . |
