It handles Layer-1 framing and D-channel access across a 4-wire IOM-2 bus, making it the digital interface between the S-bus transceiver and the host controller in terminal equipment, NT1s, or line cards. The part is housed in a 44-lead J-lead LCC (P-LCC-44-1) for surface-mount assembly and runs from a 5 V nominal supply (4.75 V to 5.25 V). ## 5 V supply and 17 mA budget — sizing the rail The supply range is tight at 4.75 V to 5.25 V — this is a 5 V ±5 % part, not a wide-range device. The 17 mA supply current (typical) is the active figure for the entire controller. On a line card with multiple channels, each PSB2186NV1.1ISACS adds about 85 mW to the 5 V rail. That is manageable for a backplane-fed design but needs factoring if the 5 V rail is derived from an on-card DC-DC with limited headroom. ## Temperature grade — indoor equipment only Rated for 0 °C to 70 °C, so this is a commercial-temperature device meant for office telecom, PBX, terminal adapters, and other indoor, temperature-controlled environments. Not for outdoor cabinets or unheated enclosures where the ambient can dip below freezing. ## Package and mounting — 44-LCC with J-leads The 44-LCC (J-Lead) package is a leaded chip carrier with J-bend leads on a 0.050-inch pitch. It is a surface-mount package that can be soldered directly to the PCB or socketed. The supplier device package is P-LCC-44-1. The J-lead form factor gives a smaller footprint than a gull-wing quad flat pack and offers decent visual inspection access after solder. ## Lifecycle — still active, no LTB risk For a BOM line that needs this ISDN controller, there is no imminent obsolescence concern.","metaTitle":"PSB2186NV1.1ISACS ISDN Access Controller, 4-Wire IOM-2","metaDescription":"Infineon PSB2186NV1.1ISACS ISAC-S TE ISDN access controller, 4-wire IOM-2 interface, 17 mA supply, 5 V.
