5 / 27 page 5 COMMERCIAL AND INDUSTRIAL TEMPERATURERANGES IDT72261LA/72271LA SuperSync FIFO™ 16,384 x 9 and 32,768 x 9 Symbol Parameter Min. Typ. Max. Unit V C C 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 OperatingTemperature 0 — +70 °C Commercial TA OperatingTemperature –40 — +85 °C Industrial Symbol Rating Com’l & Ind’l Unit VTERM TerminalVoltage –0.5 to +7 V with respect to GND TSTG Storage –55 to +125 °C Temperature IOUT DC Output Current –50 to +50 mA 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) Symbol Parameter (1) Conditions Max. Unit CIN(2) Input VIN = 0V 10 pF Capacitance COUT (1,2) Output VOUT = 0V 10 pF Capacitance NOTE: 1.5V undershoots are allowed for 10ns once per cycle. IDT72261LA IDT72271LA Commercial and Industrial(1) tCLK = 10, 15, 20 ns Symbol Parameter Min. Max. Unit ILI(2) InputLeakageCurrent –1 1 µ A ILO(3) OutputLeakageCurrent –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 — 75 mA ICC2(4,7) Standby Current — 20 mA NOTES: 1. Industrial temperature range product for the 15ns and 20ns speed grade 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 + 1.85*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. ABSOLUTE MAXIMUM RATINGS 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 this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. RECOMMENDED DC OPERATING CONDITIONS CAPACITANCE (TA = +25°C, f = 1.0MHz) |
