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.

DC ELECTRICAL CHARACTERISTICS

(Commercial: VCC = 5V ± 10%, TA = 0

°C to +70°C; Industrial: VCC = 5V ± 10%, TA = –40°C to +85°C)

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.
