DESCRIPTION

The SY100S336 functions either as a modulo-16 up/down counter or as a 4-bit bidirectional shift register and is designed for use in high-performance ECL systems. Three Select inputs (Sn) are provided for determining the mode of operation. The Function Table lists the available modes of operation.
