† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. This value is limited to 6 V maximum.
2. This value is limited to 4.6 V maximum.
3. The package thermal impedance is calculated in accordance with JESD 51.
DescriptionThis 16-bit (dual-octal) noninverting bus transceiver contains two separate supply rails; B port has VCCB , which is set at 5 V, and A port has VCCA, 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.
To ensure the high-impedance state during power up or power down, the output-enable (OE) input should be tied to VCC through a pullup resistor; theminimum value of the resistor is determined by the current-sinking capability of the driver. The SN74ALVC164245 is characterized for operation from -40 to 85C.
