Single-Wire Serial Data Input
The SN74LV8153 is a serial-to-parallel data converter. It
accepts serial input data and outputs 8-bit parallel data.
Compatible With UART Serial-Data Format
Up to Eight Devices (64-Bit Parallel) Can
Share the Same Bus by Using Different
Combinations of A0, A1, A2
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.

Up to 40 mA Current Drive in Open-Collector
Mode for Driving LEDs
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.
Outputs Can be Configured as
Open-Collector or Push-Pull
Internal Oscillator and Counter for
Automatic Data-Rate Detection
Output Levels Are Referenced to V
and
CC2
To ensure the high-impedance state during power up or
Can Be Configured From 3 V to 12 V
power down, OE should be tied to V
through a pullup
CC1
Latch-Up Performance Exceeds 250 mA Per
JESD 17
resistor; the minimum value of the resistor is determined
by the current-sinking capability of the driver.
ESD Protection Exceeds JESD 22
