5 / 27 page 5 COMMERCIAL AND INDUSTRIAL TEMPERATURE RANGE IDT72255LA/72265LA SUPERSYNC FIFO™ 8,192 x 18, 16,384 x 18 ABSOLUTE MAXIMUM RATINGS Symbol Rating Com’l & Ind’l Unit VTERM Terminal Voltage –0.5 to +7.0 V with respect to GND TSTG Storage –55 to +125 °C Temperature IOUT DC Output Current –50 to +50 mA NOTE: 1. Stresses greater than those listed under ABSOLUTE MAXIMUM RAT- INGS 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 ex- tended periods may affect reliability. NOTES: 1. With output deselected, ( OE ≥ VIH). 2. Characterized values, not currently tested. DC ELECTRICAL CHARACTERISTICS (Commercial: VCC = 5V ± 10%, TA = 0°C to +70°C; Industrial: VCC = 5V ± 10%, TA = –40°C to +85°C ) CAPACITANCE (TA = +25 °C, f = 1.0MHz) Symbol Parameter(1) Conditions Max. Unit CIN(2) Input VIN = 0V 10 pF Capacitance COUT(1,2) Output VOUT = 0V 10 pF Capacitance RECOMMENDED DC OPERATING CONDITIONS Symbol Parameter Min. Typ. Max. Unit VCC Supply Voltage 4.5 5.0 5.5 V Commercial/Industrial GND Supply Voltage 0 0 0 V VIH Input High Voltage 2.0 — — V Commercial/Industrial VIL (1) Input Low Voltage — — 0.8 V Commercial/Industrial TA Operating Temperature 0 — 70 °C Commercial TA Operating Temperature –40 — 85 °C Industrial NOTE: 1. 1.5V undershoots are allowed for 10ns once per cycle. IDT72255LA IDT72265LA Commercial & Industrial(1) tCLK = 10, 15, 20 ns Symbol Parameter Min. Max. Unit ILI(2) Input Leakage Current –1 1 µA ILO(3) Output Leakage Current –10 10 µA VOH Output Logic “1” Voltage, IOH = –2 mA 2.4 — V VOL Output Logic “0” Voltage, IOL = 8 mA — 0.4 V ICC1(4,5,6) Active Power Supply Current — 80 mA ICC2(4,7) Standby Current — 20 mA NOTES : 1. Industrial temperature range product for 15ns and 20ns speed grades are available as a standard device. 2. Measurements with 0.4 ≤ VIN ≤ VCC. 3. OE ≥ VIH, 0.4 ≤ VOUT ≤ VCC. 4. Tested with outputs disabled (IOUT = 0). 5. RCLK and WCLK toggle at 20 MHz and data inputs switch at 10 MHz. 6. Typical ICC1 = 15 + 2.1*fS + 0.02*CL*fS (in mA) with VCC = 5V, tA = 25 °C, fS = WCLK frequency = RCLK frequency (in MHz, using TTL levels), data switching at fS/2, CL = capacitive load (in pF). 7. All Inputs = VCC - 0.2V or GND + 0.2V, except RCLK and WCLK, which toggle at 20 MHz. |
