8-bit Binary Counter/Register (with 3-state outputs)
REJ03D0632-0200 (Previous ADE-205-512)
Rev.2.00 Mar 30, 2006
Description
This device each contains an 8-bit binary counter that feeds an 8-bit storage register. The storage register has parallel outputs. Separate clocks are provided for both the binary counter and storage register. The binary counter features a direct clear input CCLR and a count enable input CCKEN. For cascading a ripple carry output RCO is provided. Expansion is easily accomplished by tying RCO of the first stage to CCKEN of the second stage, etc.
Both the counter and register clocks are positive-edge triggered.
