DESCRIPTION
The SY10/100E136 are 6-bit synchronous, presettable, cascadable universal counters. These devices generate a look-ahead-carry output and accept a look-ahead-carry input. These two features allow for the cascading of multiple E136s for wider bit width counters that operate at very nearly the same frequency as the stand-alone counter.

FEATURES
■ 550MHz count frequency
■ Extended 100E VEE range of –4.2V to –5.5V
■ Look-ahead-carry input and output
■ Fully synchronous up and down counting
■ Asynchronous Master Reset
■ Internal 75KΩ input pull-down resistors
■ Available in 28-pin PLCC package
