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.
