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.
DC ELECTRICAL CHARACTERISTICS
(Commercial: VCC = 5V ± 10%, TA = 0
°C to +70°C; Industrial: VCC = 5V ± 10%, TA = -40°C to +85°C)
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.
