www.ti.com SCLS555 − JUNE 2004 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.

Two consecutive serial-data frames transmit 8 bits of data. The first frame includes the lower four bits of data (D0-D3), and the second frame includes the upper four bits (D4-D7). − The three address bits (in the consecutive frame) must be the same as those in the first frame; otherwise, the data will be dropped. − The order of the two start bits must be 0, then 1 in any frame; otherwise, the data rate will not be detected correctly. The period between the falling edge of the first start bit (ST0) and the rising edge of the second start bit (ST1) is measured to generate an internal-clock synchronized data stream. 1st Frame ST0 A0 A1 A2 2nd Frame D0 D1 D2 ST0 D3 ST1 SP A0 A1 A2 D4 D5 D6 D7 ST1 SP Example of Serial-Data Format ST0 DATA ST0 ST1 A0 A1 A2 D0 D1 D2 D3 SP ST1 A0 A1 A2 D4 D5 D6 D7 SP Internal Clock Y0−Y7 SOUT Timing Chart (1)Internal clock cannot be observed.

TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
