6 / 16 page Philips Semiconductors Product specification 74F1763 Intelligent DRAM controller (IDC) 1999 Jan 08 6 ABSOLUTE MAXIMUM RATINGS Operation beyond the limits set forth in this table may impair the useful life of the device. Unless otherwise noted, these limits are over the operating free-air temperature range. SYMBOL PARAMETER RATING UNIT VCC Supply voltage –0.5 to +7.0 V VIN Input voltage –0.5 to +7.0 V IIN Input current –30 to +5 mA VOUT Voltage applied to output in High output state –0.5 to +VCC V IOUT Current applied to output in Low output state 120 mA TA Operating free-air temperature range 0 to +70 _C TSTG Storage temperature –65 to +150 _C RECOMMENDED OPERATION CONDITIONS SYMBOL PARAMETER LIMITS UNIT SYMBOL PARAMETER MIN NOM MAX UNIT VCC Supply voltage 4.5 5.0 5.5 V VIH High-level input voltage 2.0 V VIL Low-level input voltage 0.8 V IIK Input clamp current –18 mA IOH High-level output current1 –15 mA IOL Low-level output current1 24 mA TA Operating free-air temperature range 0 70 _C NOTE: 1. Transient currents will exceed these values in actual operation. DC ELECTRICAL CHARACTERISTICS Over recommended operating free-air temperature range unless otherwise noted.

For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type. 2. All typical values are at VCC = 5V, TA = 25_C. 3. IOH2 is transient current necessary to guarantee a Low to High transition in a 70W transmission line. 4. IOL2 is transient current necessary to guarantee a High to Low transition in a 70W transmission line. 5. Not more than one output should be shorted at a time. For testing IOS, the use of high-speed test apparatus and/or sample-and-hold techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting of a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any sequence of parameter tests, IOS tests should be performed last. |
