1. Stresses greater than those listed under ABSOLUTE MAXIMUM RAT-
INGS 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.

1. Industrial temperature range product for the 15ns and the 25 ns 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 open (IOUT = 0).
5. RCLK and WCLK toggle at 20 MHZ and data inputs switch at 10 MHz.
6. For the 72205/72215/72225 the typical ICC1 = 1.81 + 1.12*fS + 0.02*CL*fS (in mA);
for the 72235/72245 the typical ICC1 = 2.85 + 1.30*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.
