DC ELECTRICAL CHARACTERISTICS

(Commercial: VCC = 3.3V ± 0.3V, TA = 0

°C to +70°C; Industrial: VCC = 3.3V

± 0.3V, 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.

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 = 2.04 + 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.

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.

2. VCC terminal only.
