The SN65ELT20 is a TTL-to-differential PECL
translator. It operates on a 5-V supply and ground
only. The output is undetermined when the inputs are
left floating. The low output skew makes the device
an ideal solution for clock or data signal translation. P0065-04 The SN65ELT20 is housed in an industry-standard
SOIC-8 package and is also available in a TSSOP-8
package. Table 1. Pin Description
