NOTES:

1. Industrial temperature range product for the 15ns and 25 ns speed grades are available as a standard device.

2. Military speed grades of 50ns and 80ns are only available for the IDT7201LA.

3. Measurements with 0.4

≤ VIN ≤ VCC.

4.

R

≥ VIH, 0.4 ≤ VOUT ≤ VCC.

5. Tested with outputs open (IOUT = 0).

6. Tested at f = 20 MHz.

7. Typical ICC1 = 15 + 2*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).

8. All Inputs = VCC - 0.2V or GND + 0.2V.
