description

This 16-bit (dual-octal) noninverting bus transceiver contains two separate supply rails; B port has V_CCB, which is set at 5 V, and A port has V_CCA, which is set to operate at 3.3 V. This allows for translation from a 3.3-V to a 5-V environment and vice-versa.

The SN74ALVC164245 is designed for asynchronous communication between data buses.

The SN74ALVC164245 is available in TI's shrink small-outline (DL) and thin shrink small-outline (DGG) packages, which provide twice the I/O pin count and functionality of standard small-outline packages in the same printed-circuit-board area.

To ensure the high-impedance state during power up or power down, 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 SN74ALVC164245 is characterized for operation from -40°C to 85°C.
