DESCRIPTION

The 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 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, 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.
