Analog Devices Inc. ADM306x介面RS-485收發器
Analog Devices ADM306x介面RS-485收發器是3.0V至5.5V、IEC靜電放電(ESD)保護的RS-485收發器。這允許該裝置可在收發器匯流排引腳上承受±12kV觸點放電，而不會閉鎖或損壞。ADM306x採用VIO邏輯引腳，允許能以低至1.62V運作的理念幹活數位介面。ADM3065E/ADM3066E/ADM3067E/ADM3068E適用於多點匯流排傳輸線路上的高速、50Mbps、雙向資料通訊。ADM3061E/ADM3062E/ADM3063E/ADM3064E採用1/4單位負載輸入電阻，允許匯流排上採用最多128個收發器。ADM3061E/ADM3062E/ADM3063E/ADM3064E型號與ADM3065E/ADM3066E/ADM3067E/ADM3068E型號在500kbps低資料速率時提供完全相同的功能，適合長線纜鋪設運作。
Analog Devices Inc. ADM3061E/ADM3062E/ADM3065E/ADM3066E are half-duplex RS-485 transceivers, fully compliant to the PROFIBUS® standard with increased 2.1V bus differential voltage at VCC ≥ 4.5V. The ADM3063E/ADM3064E/ADM3067E/ADM3068E are full-duplex RS-485 transceiver options. The RS-485 transceivers are available in several space-saving packages. These packages include the 10-lead, 3mm × 3mm lead-frame chip-scale package (LFCSP), the 8-lead or 10-lead, 3mm x 3mm mini small outline package (MSOP), and the 8-lead or 14-lead, narrow-body standard small-outline packages (SOIC_N). Models with operating temperature ranges of −40°C to +125°C and −40°C to +85°C are available.
