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.

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. R ≥ VIH, 0.4 ≤ VOUT ≤ VCC.
4. Tested with outputs open (IOUT = 0).
5. Tested at f = 20 MHz.
6. Typical ICC1 = 2*[15 + 2*fS + 0.02*CL*fS] (in mA) with VCC = 5V, TA = 25oC, 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.
