Packaging

Type 8-SOIC, surface-mount, supplied in tubes

Material Molded epoxy plastic body with metal leadframe (typical for SOIC)

Size Body width 3.90 mm (0.154"); compact 8-pin outline for dense layouts

Pin configuration 8 pins total; typical mapping includes two TTL inputs, two differential PECL output pairs (Q/Q̄ for each channel), VCC, and GND. Refer to the datasheet for exact pin names and arrangement.

Thermal characteristics Designed for -40°C to +85°C ambient operation; SOIC package supports standard thermal dissipation on typical FR-4 boards with proper copper areas and airflow

Electrical properties Unidirectional translation from TTL input thresholds to PECL output levels; differential outputs suited to controlled-impedance traces and standard PECL terminations. For precise logic thresholds, output swing, and recommended terminations, consult the datasheet.

Lifecycle

Status The MC100ELT family is mature. This specific MC100ELT22D variant is RoHS non-compliant, so availability may be limited depending on regional compliance needs.

Equivalent or alternative models

- MC100ELT22DG Pb-free/RoHS-compliant 8-SOIC variant of the same function (check exact ordering code and package finish)

- MC100ELT22DR2G Tape-and-reel, Pb-free/RoHS-compliant packaging option (verify availability)

- MC10ELT22D Related 3.3 V family translator for designs targeting LVPECL biasing (verify voltage, thresholds, and performance fit)

- Other PECL/LVPECL TTL translators from onsemi or cross-vendors may fit; exact pinout and electrical compatibility must be checked
