Industrial Temperature Range Product for the 15ns and the 25ns 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. For the IDT72205/72215/72225 the typical ICC1 = 1.81 + 1.12*fS + 0.02*CL*fS (in mA); for the IDT72235/72245 the typical ICC1 = 2.85 + 1.30*fS + 0.02*CL*fS (in mA) These equations are valid under the following conditions: 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 NOTES: 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. ICC2(4,7) StandbyCurrent — — 5 mA |
