NOTES:
1. 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 disabled (IOUT = 0).
5. RCLK and WCLK toggle at 20 MHZ and data inputs switch at 10 MHz.
6. Typical ICC1 = 2[2.04 + 0.88*fS + 0.02*CL*fS] (in mA).
These equations are valid under the following conditions:
VCC = 3.3V, 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.
