3 / 17 page ![]() 5.14 3 IDT72251 CMOS SyncFIFO ™ 8192 x 9 COMMERCIAL TEMPERATURE RANGES ABSOLUTE MAXIMUM RATINGS(1) Symbol Rating Commercial Unit VTERM Terminal Voltage –0.5 to +7.0 V with Respect to GND TA Operating 0 to +70 °C Temperature TBIAS Temperature –55 to +125 °C Under Bias TSTG Storage –55 to +125 °C Temperature IOUT DC Output 50 mA Current NOTE: 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 the specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. 2655 tbl 02 RECOMMENDED OPERATING CONDITIONS Symbol Parameter Min. Typ. Max. Unit VCCC Commercial 4.5 5.0 5.5 V Supply Voltage GND Supply Voltage 0 0 0 V VIH Input High Voltage 2.0 — — V Commercial VIL Input Low Voltage — — 0.8 V Commercial CAPACITANCE (TA = +25 °C, f = 1.0MHz) Symbol Parameter Conditions Max. Unit CIN (2) Input Capacitance VIN = 0V 10 pF COUT (1,2) Output Capacitance VOUT = 0V 10 pF NOTES: 1. With output deselected ( OE = HIGH). 2. Characterized values, not currently tested. IDT72251 Commercial tCLK = 15, 20, 25, 35 Symbol Parameter Min. Typ. Max. Unit ILI (1) Input Leakage Current (Any Input) -1 — 1 µA ILO (2) Output Leakage Current -10 — 10 µA VOH Output Logic “1” Voltage, IOH = –2mA 2.4 — — V VOL Output Logic “0” Voltage, IOL = 8mA — — 0.4 V ICC1 (4) Active Power Supply Current — — 80 mA NOTES: 1. Measurements with 0.4 ≤ VIN ≤ VCC. 2. OE ≥ VIH, 0.4 ≤ VOUT ≤ VCC. 3 & 4. Measurements are made with outputs unloaded. Tested at fCLK = 20MHz. (3) Typical ICC1 = 30 + (fCLK*0.5/MHz) + (fCLK*CL*0.02/MHz-pF) mA (4) Typical ICC1 = 32 + (fCLK*0.6/MHz) + (fCLK*CL*0.02/MHz-pF) mA fCLK = 1/tCLK. CL = external capacitive load (30pF typical) (Commercial: VCC = 5V ± 10%, TA = 0°C to + 70°C) DC ELECTRICAL CHARACTERISTICS |
