FEATURES
DESCRIPTION
The SY10/100ELT28 is a differential PECL-to-TTL translator and a TTL-to-differential PECL translator in a single package. Because PECL (Positive ECL) levels are used, only +5V and ground are required. The small outline 8-pin package and the dual translation design of the ELT28 makes it ideal for applications which are sending and receiving signals across a backplane.
FEATURES
■ Guaranteed AC parameters over temperature:
• fMAX > 160MHz (TTL)
• < 5.5ns PECL-to-TTL propagation delay
• < 1.5ns tr / tf; PECL output
• < 1.3ns TTL-to-PECL propagation delay
■ Wide temperature range: –40°C to +85°C
■ 5V power supply
■ QTTL output will default low with inputs left open or < 1.3V
■ QECL output will default high with inputs left open
■ Internal PECL input pulldown resistors
■ Available in 8-pin MSOP and SOIC packages
