SK10/100ELT21W
Differential PECL to CMOS/TTL or LVPECL to LVCMOS/LVTTL Translator
HIGH-PERFORMANCE PRODUCTS Description
The SK10/100ELT21W is a single differential PECL to CMOS/TTL or LVPECL to LVCMOS/LVTTL Translator. Since PECL (Positive ECL) levels are used, only +VCC and ground are required. The small outline, 8 lead SOIC package, low skew, and the single gate design of the SK10/100ELT21W makes it ideal for applications which require the translation of a clock and a data signal. Unlike the TTL totem pole outputs, the outputs of the ELT21W can be interfaced directly to CMOS inputs with better VOH (VCC
- 0.5V) levels. With extended supply voltage capability, the device is functionally patible with MC10/100ELT21 (5V) and MC10/100LVELT21 (3.3V).
