The SN74LVC157A features a common strobe (G) input. When the strobe is high, all outputs are low. When the strobe is low, a 4-bit word is selected from one of two sources and is routed to the four outputs. The device provides true data. Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators in a mixed 3.3-V/5-V system environment. The SN74LVC157A is characterized for operation from 40C to 85C.

Requires a 27 MHz reference clock for ED operation or a 74.25 MHz reference clock for HD operation. 50 S_HSYNC I/O SD Horizontal Synchronization Signal. This pin can also be configured to output an SD, ED, or HD horizontal synchronization signal. See the External Horizontal and Vertical Synchronization Control section. 49 S_VSYNC I/O SD Vertical Synchronization Signal. This pin can also be configured to output an SD, ED, or HD vertical synchronization signal. See the External Horizontal and Vertical Synchronization Control section. 22 P_HSYNC I ED/HD Horizontal Synchronization Signal. See the External Horizontal and Vertical Synchronization Control section. 23 P_VSYNC I ED/HD Vertical Synchronization Signal.

See the External Horizontal and Vertical Synchronization Control section. 48 SFL/MISO I/O Multifunctional Pin: Subcarrier Frequency Lock (SFL) Input/SPI Data Output. The SFL input is used to drive the color subcarrier DDS system, timing reset, or subcarrier reset. 47 RSET1 I This pin is used to control the amplitudes of the DAC 1, DAC 2, and DAC 3 outputs. For full-drive operation (for example, into a 37.5 load), a 510 resistor must be connected from RSET1 to AGND. For low drive operation (for example, into a 300 load), a 4.12 k resistor must be connected from RSET1 to AGND. harman/kardonDVD 39/DVD 49 service manual Page 59 of 113 AM5888S Motor Driver ICs A AMMt te ek k S SE EMMI IC COON ND DU UC CT TOOR RS S F Fe eb b 2 20 00 05 5 V V1 1. .2 2 - 4 - ?
