M74HC590 8 BINARY COUNTER REGISTER

The M74HC590 is an high speed CMOS 8-BIT BINARY COUNTER REGISTER (3 STATE) fabricated with silicon gate C2MOS technology. This device 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 cou.

SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = I OL = 6mA (MIN) for QA ~ QH OUTPUT |IOH| = IOL = 4mA (MIN) for RCO OUTPUT BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL WIDE OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 590 DIP SOP TSSOP ORDER C.

M74HC590 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. If the user wishes to
