SY10E141 SY100E141 Micrel, Inc. 8-BIT SHIFT SY10E141 SY100E141 REGISTER FEATURES DESCRIPTION 700MHz min. shift frequency The SY10/100E141 are 8-bit, full-function shift registers designed for use in new, high-performance ECL systems. Extended 100E VEE range of 4.2V to 5.5V The E141 performs serial/parallel in and serial/parallel out, 8 bits wide shifting in either direction. The eight inputs D0D7 accept Bi-directional parallel input data, while DL/DR accept serial input data for Four selectable modes for full functionality left/right shifting. The two select pins, SEL0 and SEL1 permit four modes Asynchronous Master Reset of operation: Load, Hold, Shift Left and Shift Right, as Fully compatible with industry standard 10KH, shown in the Truth Table. Input data is clocked into the 100K ECL levels register on the rising clock edge after meeting the minimum Internal 75K input pulldown resistors set-up time. A logic HIGH on the Master Reset (MR) pin Fully compatible with Motorola MC10E/100E141 asynchronously resets all the registers to zero.
