DESCRIPTION  
by the SCL clock input, with both modes sharing a  
commonSDAinput/output(I/O).Thetransmit-onlymode  
is a read-only mode, while the bi-directional mode is a  
read and write mode following the I2C protocol. In write  
mode the CAT24C21 features a 16-byte page write  
buffer.Thedeviceisavailablein8-inDIP,SOIC,TSSOP,  
MSOP and TDFN packages.  
The CAT24C21 is a 1-kb Serial CMOS EEPROM  
internally organized as 128 words of 8 bits each. The  
device complies with the Video Electronics Standard  
Association's(VESA™),DisplayDataChannel(DDC™)  
standards for "Plug-and-Play" monitors. The "transmit-  
only" mode (DDC1™) is controlled by the VCLK clock  
inputandthe"bi-directional"mode(DDC2™)iscontrolled
