(1) 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.
(1)The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
(2)The value of VCC is provided in the recommended operating operating condition table.
(3)The package thermal impedance is calculated in accordance with JESD 51-7.
DescriptionThe SN74LV8153 is a serial-to-parallel data converter. It accepts serial input data and outputs 8-bit parallel data.
The automatic data-rate detection feature of the SN74LV8153 eliminates the need for an external oscillator and helps with cost and board real-estate savings.
The SN74LV8153 OUTSEL pin is used to choose between open collector and push-pull outputs. The open-collector option is suitable when this device is used in applications such as LED interface, where high drive current is required. SOUT is the output that acknowledges reception of the serial data.
To ensure the high-impedance state during power up or power down, SN74LV8153 OE should be tied to VCC1 through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
