Notes:

1. Device tested and characterized under TA conditions specified, with TC monitored at approximately 20° higher than TA.

2. PD is multiplying the max VCC by the max ICC and subtracting the power dissipated outside the chip at the high speed bias resistors.

3. Typical specified with VCC = 3.3 volts, maximum specified with VCC = 3.45 volts.

4. Specified with high speed outputs biased with 150 Ω resistors and receiver TTL outputs driving 10 pF loads.

5. Based on independant package testing by HP. Θja for these devices is 48°C/Watt for the HDMP-1536 and 44°C/Watt for the

HDMP-1546. Θja is measured on a standard 3x3" FR4 PCB in a still air environment. To determine the actual junction temperature

in a given application, use the value as described as follows: Tj = TC + (Θjc x Pd), where TC is the case temperature measured on

the top center of the package and PD is the power being dissipated.
