| Micrel, Inc. 9-BIT HOLD REGISTER SY10E143 SY100E143 SY10E143 SY100E143 FEATURES s s s s s s 700MHz min. operating frequency Extended 100E VEE range of -4.2V to -5.5V 9 bits wide for byte-parity applications Asynchronous Master Reset Dual clocks Fully compatible with industry standard 10KH, 100K ECL levels s Internal 75k input pulldown resistors s Fully compatible with Motorola MC10E/100E143 s Available in 28-pin PLCC package DESCRIPTION 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. The input data has to meet the set-up time before being clocked into the nine input registers on the rising edge of CLK1 or CLK2. The MR (Master Reset) control signal asynchronously resets all nine registers to a logic LOW when a logic HIGH is applied to MR. The E143 is designed for applications requiring highspeed registers, pipeline registers, synchronous operation, and is also suitable for byte-wide parity.
