This 16-bit noninverting bus transceiver uses two separate configurable power-supply rails. The  SN74AVC16T245 is optimized to operate with V_CCA/V_CCB set at 1.4 V to 3.6 V. It is operational with V_CCA/V_CCB as low as 1.2 V. The A port is designed to track V_CCA. V_CCA accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track V_CCB. V_CCB accepts any supply voltage from 1.2 V to 3.6 V. This allows for universal low-voltage bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes.

The SN74AVC16T245 is designed for asynchronous communication between data buses. The device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable （OE ）input can be used to disable the outputs so the buses are effectively isolated.

The SN74AVC16T245 is designed so that the control pins (1DIR, 2DIR, 1OE , and 2OE ) are supplied by V_CCA.

This device is fully specified for partial-power-down applications using I off. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.

The V_CC isolation feature ensures that if either V_CC  input is at GND, both ports are in the high-impedance state.To ensure the high-impedance state during power up or power down, OE should be tied to V_CC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

The MCP1701 is a family of CMOS low dropout (LDO), positive voltage regulators that can deliver up to 250 mA of current while consuming only 2.0 μA of quiescent current (typical). The input operating range is specified up to 10V, making it ideal for lithium-ion (one or two cells), 9V alkaline and other two and three primary cell battery-powered applications.

The MCP1701 is capable of delivering 250 mA with an input-to-output voltage differential (dropout voltage) of 650 mV. The low dropout voltage extends the battery operating lifetime. It also permits high currents in small packages when operated with minimum VIN – VOUT differentials.

The MCP1701 has a tight tolerance output voltage regulation of ±0.5% (typical) and very good line regulation at ±0.2%. The LDO output is stable when using only 1 μF of output capacitance of either tantalum or aluminum-electrolytic style capacitors. The MCP1701 LDO also incorporates short-circuit protection to ensure maximum reliability.

Package options include the 3-Pin SOT-23A, 3-Pin SOT-89 and 3-Pin TO-92.
