5 / 8 page  5 LTC1385 sn1385 1385fas VCC: 3.3V Input Supply Pin. This pin should be decoupled with a 0.1 µF ceramic capacitor. GND: Ground Pin. ON/OFF: TTL/CMOS Compatible Shutdown Pin. A logic low puts the device in the Shutdown mode independent of the Driver Disable pin. The supply current drops to 0.2 µA and all driver and receiver outputs are forced into three-state. DRIVER DISABLE: TTL/CMOS Compatible Input Pin. With the ON/OFF pin held high, a logic low forces the part into the Driver Disable mode with the charge pump turned off and the driver outputs forced into three-state. Both receiv- ers remain active and the supply current drops to 35 µA. A logic high forces the part into the Normal mode. V+: Positive Supply Output (EIA/TIA-562 Drivers). V+ ≅ 2VCC – 1V. This pin requires an external capacitor C = 0.1 µF for charge storage. The capacitor may be tied to ground or VCC. With multiple devices, the V + and V– pins may share a common capacitor. For a large number of devices, increasing the size of the shared common storage capacitors is recommended to reduce ripple. V–: Negative Supply Output (EIA/TIA-562 Drivers). V – ≅ –(2VCC – 1.3V). This pin requires an external capacitor C = 0.1 µF for charge storage. C1+, C1–, C2+, C2–: Commutating Capacitor Inputs. These pins require two external capacitors C = 0.1 µF: one from C1+ to C1–, and another from C2+ to C2–. To maintain charge pump efficiency, the capacitor’s effective series resistance should be less than 2 Ω. TR IN: EIA/TIA-562 Driver Input Pins. Inputs are TTL/ CMOS compatible. The inputs of unused drivers can be left unconnected since 300k input pull-up resistors to VCC are included on chip. To minimize power consumption, the internal driver pull-up resistors are disconnected from VCC in the Shutdown mode. TR OUT: Driver Outputs at EIA/TIA-562 Voltage Levels. Outputs are in a high impedance state when in the Shut- down or Driver Disable mode or VCC = 0V. The driver outputs are protected against ESD to ±10kV for human body model discharges. RX IN: Receiver Inputs. These pins can be forced to ±25V without damage. The receiver inputs are protected against ESD to ±10kV for human body model discharges. Each receiver provides 0.4V of hysteresis for noise immunity. RX OUT: Receiver Outputs with TTL/CMOS Voltage Lev- els. Outputs are in a high impedance state when in the Shutdown mode. 1.4V 0V VCC 0V V+ V– 0V DRIVER INPUT DRIVER OUTPUT 1.4V tHLD tLHD 1385 F01 Figure 1.
