BLOCK DIAGRAM
DESCRIPTION
The CTS100ELT22 is a dual CMOS/TTL to differential PECL translator. Because PECL (Positive ECL) levels are used, only VCC and ground are required. The small outline packaging and the low skew, dual gate design of the CTS100ELT22 makes it ideal for applications that require the translation of a clock and a data signal.
The CTS100ELT22 is a direct replacement for the ON Semi MC100ELT22, MC100LVELT22 and Micrel SY89322V.
ENGINEERING NOTES
When the D input is left floating, the Q output is forced HIGH, and the Q output is forced LOW.
