DESCRIPTION
Add R1 at end of part number for 7 inch (1K parts), R2 for 13 inch (2.5K parts) Tape & Reel. Date code format: “Y” or “YY” for year followed by “WW” for week. Parts marked JNB for date codes prior to 4WW (prior to 2004). Date code “YWW” or “YYWW” on underside of part. This information can be used with the /EN input pin to disable the output under loss of signal conditions. The detect threshold can be set with a resistor divider between VCC and VREF. The SD output is an open drain compatible with CMOS and TTL. The outputs produce standard PECL 100K voltage compensated levels. PINDESCRIPTION
