SN74AVCH1T45的产品详情:

The SN74AVCH1T45 is a single-bit noninverting bus transceiver that uses two separate configurable power-supply rails. The A port is designed to track VCCA, which accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track VCCB, which also 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 SN74AVCH1T45 is designed for asynchronous communication between two data buses. The device transmits data from either the A bus to the B bus, or from the B bus to the A bus, depending upon the logic level at the direction-control (DIR) input.

The SN74AVCH1T45 is designed so that the DIR input is referenced to VCCA.

Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors with the bus-hold circuitry is not recommended.

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

The VCC isolation feature ensures that if either VCCA or VCCB is at GND, then the outputs are in the high-impedance state. The bus-hold circuitry on the powered-up side always stays active.

NanoFree package technology is a major breakthrough in IC packaging concepts, using the die as the package.
