SY100E141 DESCRIPTION 700MHz min. shift frequency Extended 100E VEE range of –4.2V to –5.5V 8 bits wide Bi-directional Four selectable modes for full functionality Asynchronous Master Reset Fully compatible with industry standard 10KH, 100K ECL levels Internal 75KΩ input pulldown resistors Fully compatible with Motorola MC10E/100E141 Pin-compatible with E241 Available in 28-pin PLCC package The SY10/100E141 are 8-bit, full-function shift registers designed for use in new, high-performance ECL systems. The E141 performs serial/parallel in and serial/parallel out, shifting in either direction. The eight inputs D0–D7 accept parallel input data, while DL/DR accept serial input data for left/right shifting. The two select pins, SEL0 and SEL1 permit four modes of operation: Load, Hold, Shift Left and Shift Right, as shown in the Truth Table. Input data is clocked into the register on the rising clock edge after meeting the minimum set-up time. A logic HIGH on the Master Reset (MR) pin asynchronously resets all the registers to zero.
