The package includes 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 dissipation. The heat sink is electrically connected to the VDD supply of the chip and therefore must be isolated from all other signals. HOLT INTEGRATED CIRCUITS 6 RADIATION TOLERANCE The HI-1567 has been characterized for total dose radiation performance in accordance with MIL-STD-883 method 1019. The part meets all data sheet parameters after exposure to 25 KRad(Si). APPLICATIONS NOTE Holt Applications Note AN-500 provides circuit design notes regarding the use of Holt's family of MIL-STD-1553 transceivers. Layout considerations, as well as recommended interface and protection components are included. |
