SN74LV8153-Q1 Datasheet, PDF (1/14 Pages) Texas Instruments – SERIAL-TO-PARALLEL INTERFACE

www.ti.com
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 V_CC1 through a pullup
resistor; the minimum value of the resistor is determined
by the current-sinking capability of the driver.
