Notes:
1. PD is calculated by multiplying the max V_CC by the max I_CC and subtracting the power dissipated outside the chip at the high speed
bias resistors.
2. Typical specified with V_CC = 5 volts, maximum specified with V_CC = 5.25 volts.
3. Specified with high speed outputs biased with 270 Ω resistors and receiver TTL outputs driving 10 pF loads. Pattern is PRBS 2⁷-1.
4. Based on independant package testing by HP.
