NOTES:
1. Industrial temperature range product for the 15ns and 25ns speed grades are available as standard product.
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 = 1.7 + 0.7*fS + 0.02*CL*fS (in mA).
These equations are valid under the following conditions:
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

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 the specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.
