NOT RECOMMENDED FOR NEW DESIGNS SY10E143 SY100E143 Micrel, Inc. 9-BIT HOLD SY10E143 SY100E143 REGISTER FEATURES DESCRIPTION The SY10/100E143 are high-speed 9-bit hold registers 700MHz min. operating frequency designed for use in new, high-performance ECL systems. Extended 100E VEE range of 4.2V to 5.5V The E143 can hold current data or load new data. The nine 9 bits wide for byte-parity applications inputs, D0-D8, accept parallel input data. Asynchronous Master Reset The SEL (Select) control pin serves to determine the mode of operation either HOLD or LOAD. The input data Dual clocks has to meet the set-up time before being clocked into the Fully compatible with industry standard 10KH, nine input registers on the rising edge of CLK1 or CLK2. 100K ECL levels The MR (Master Reset) control signal asynchronously Internal 75k input pulldown resistors resets all nine registers to a logic LOW when a logic HIGH Fully compatible with Motorola MC10E/100E143 is applied to MR. The E143 is designed for applications requiring high- Available in 28-pin PLCC package speed registers, pipeline registers, synchronous operation, and is also suitable for byte-wide parity.
