Industrial Temperature Range Product for the 15ns speed grade is available as a standard device. 2. Measurements with 0.4 ≤ VIN ≤ VCC. 3. OE ≥ VIH, 0.4 ≤ VOUT ≤ VCC. 4. Tested with outputs open (IOUT = 0). 4. RCLK and WCLK toggle at 20 MHZ and data inputs switch at 10 MHz. 5. For the IDT72805LB/72815LB/72825LB the typical ICC1 = 2[1.81 + 1.12*fS + 0.02*CL*fS] (in mA); for the IDT72845LB the typical ICC1 = 2[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 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. Symbol Parameter Min. Typ. Max.
