SY10ELT28KITR中文资料麦瑞半导体数据手册PDF规格书

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
