NOTES:
1. Industrial temperature range product for 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 open (IOUT = 0).
5. RCLK and WCLK toggle at 20 MHz and data inputs switch at 10 MHz.
6. Typical ICC1 = 20 + 1.8*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.
