HEAT SINK - ESOIC PACKAGES
Both the 14-pin and 16-pin thermally enhanced SOIC
packages are used for HI-318X products. These ESOIC
packages include a metal heat sink located on the bottom
surface of the device. This heat sink should be soldered
down to the printed circuit board for optimum thermal
HI-318X PACKAGE THERMAL CHARACTERISTICS
Notes:
1. All data taken
2. At 100% duty cycle, 15V power supplies. For 12V power supplies multiply all tabulated values by 0.8.
3. High Speed: Data Rate = 100 Kbps, Load: R = 400 Ohms, C = 10 nF. Data not presented for C = 30 nF
4. Similar results would be obtained with A
5. For applications requiring survival with continuous short circuit, operation above Tj = 175°C is not recommended.
6. Data will vary depending on air flow and the method of heat sinking employed.
7. Current values listed are for each of the +V and -V supplies.

chip and can be soldered to any ground or power plane.
However, since the chip’s substrate is at +V, connecting
the heat sink to this power plane is recommended to avoid
coupling noise into the circuit.
