7 / 20 page  7 LTC1321/LTC1322/LTC1335 VDD(Pin 1): Positive Supply Input for EIA/TIA-562 Drivers. B1: (Pin 2): Receiver Input. A1 (Pin 3): Receiver Input. Z1 (Pin 4): Driver Output. Y1 (Pin 5): Driver Output. SEL1 (Pin 6): Interface Mode Select Input. SEL2 (Pin 7): Interface Mode Select Input. Y2 (Pin 8): Driver Output. Z2 (Pin 9): Driver Output. A2 (Pin 10): Receiver Input. B2 (Pin 11): Receiver Input. GND (Pin 12): Ground. VEE (Pin 13): Negative Supply. NC (Pin 14): No Connection. RA2 (Pin 15): Receiver Output. DE2 (Pin 16): Driver Enable with Internal Pull-Up in RS485 Mode. DY2 (Pin 17): Driver Input. ON/OFF (Pin 18): A HIGH logic input enables the trans- ceivers. A LOW puts the device into shutdown mode and reduces ICC to 15µA. This pin has an internal pull-up. LB (Pin 19): Loopback Control Input. A LOW logic level enables loopback connections. This pin has an internal pull-up. DY1 (Pin 20): Driver Input. DE1 (Pin 21): Driver Enable with Internal Pull-Up in RS485 Mode. RA1 (Pin 22): Receiver Output. NC (Pin 23): No Connection. VCC (Pin 24): Positive Supply; 4.75V ≤ VCC ≤ 5.25V. OE/VDD (Pin 1): For LTC1335, pin 1 is the receiver output enable with internal pull-down. For LTC1322, pin 1 is the positive supply input for EIA/TIA-562 drivers. B1: (Pin 2): Receiver Input. A1 (Pin 3): Receiver Input. Z1 (Pin 4): Driver Output. Y1 (Pin 5): Driver Output. SEL1 (Pin 6): Interface Mode Select Input. SEL2 (Pin 7): Interface Mode Select Input. Y2 (Pin 8): Driver Output. Z2 (Pin 9): Driver Output. A2 (Pin 10): Receiver Input. B2 (Pin 11): Receiver Input. GND (Pin 12): Ground. VEE (Pin 13): Negative Supply. RB2 (Pin 14): Receiver Output. RA2 (Pin 15): Receiver Output. DZ2/DE2 (Pin 16): EIA/TIA-562 Driver Input in EIA562 Mode. RS485 Driver Enable with Internal Pull-Up in RS485 Mode. DY2 (Pin 17): Driver Input. ON/OFF (Pin 18): A HIGH logic input enables the transceivers. A LOW puts the device into shutdown mode and reduces ICC to 15µA. This pin has an internal pull-up. LB (Pin 19): Loopback Control Input. A LOW logic level enables loopback connections. This pin has an internal pull-up. DY1 (Pin 20): Driver Input. DZ1/DE1 (Pin 21): EIA/TIA-562 Driver Input in EIA562 Mode. RS485 Driver Enable with Internal Pull-up in RS485 Mode. RA1 (Pin 22): Receiver Output. RB1 (Pin 23): Receiver Output. VCC (Pin 24): Positive Supply; 4.75V ≤ VCC ≤ 5.25V. PI FU CTIO S LTC1321 LTC1322/LTC1335 |
