UNISONIC TECHNOLOGIES CO., LTD U74HC590 CMOS IC 8-BIT BINARY COUNTERS WITH 3-STATE OUTPUT REGISTERS DESCRIPTION The UTC 74HC590 contains an 8-bit binary counter that feeds an 8-bit storage register and 3-state outputs.. The storage register has parallel (QA~QH) outputs. SOP-16 The binary counter features direct clear ( CCLR ) and count-enable ( CCKEN ) inputs. A ripple-carry output ( RCO ) is provided for cascading. Expansion is accomplished easily for two stages by connecting ( RCO ) of the first stage to CCKEN of the second stage. Cascading for larger count chains can be accomplished by connecting( RCO )of each stage to the counter clock (CCLK) input of the following stage. FEATURES * Wide supply voltage range from 2.0V to 6.0V * Low static power consumption; ICC=8μA (Max.) * 8 bit counter with register ORDERING INFORMATION Ordering Number U74HC590G-S16-R Package SOP-16 Packing Tape Reel MARKING www.unisonic.com.tw Copyright © 2016 Unisonic Technologies Co., Ltd 1 of 8 QW-R126-044.A U74HC590 CMOS IC PIN CONFIGURATION FUNCTION TABLE INPUTS OE RCLK CCLR CCKEN CCLK FUNCTION H X X X X Outputs QA-QH are disabled.
