SY100E143 Datasheet (Micrel Semiconductor)

SY100E143, 9-BIT HOLD REGISTER

The SY10/100E143 are high-speed 9-bit hold registers designed for use in new, high-performance ECL systems.

The E143 can hold current data or load new data.

The nine inputs, D0-D8, accept parallel input data.

The SEL (Select) control pin serves to determine the mode of operation; either HOLD or LOAD
