DESCRIPTION

The M54/74HC590 is a high speed CMOS 8-BIT BINARY COUNTER REGISTER (3-STATE) fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption.

¡ö HIGH SPEED fMAX = 62 MHz (TYP.) AT VCC = 5 V

¡ö LOW POWER DISSIPATION ICC = 4 ?A (MAX.) AT TA = 25 ¡ãC

¡ö HIGH NOISE IMMUNITY VNIH = VNIL = 28 VCC (MIN.)

¡ö OUTPUT DRIVE CAPABILITY 10 LSTTL LOADS (for RCO) 15 LSTTL LOADS (for QA ¡« QH)

¡ö SYMMETRICAL OUTPUT IMPEDANCE |IOH| = |IOL| = 6 mA (MIN.)FORQA~ QHOUTPUT |IOH| = |IOL| = 4 mA (MIN.) FOR RCO OUTPUT

¡ö BALANCED PROPAGATION DELAYS tPLH = tPHL

¡ö WIDE OPERATING VOLTAGE RANGE VCC (OPR) = 2 V TO 6 V

¡ö PIN AND FUNCTION COMPATIBLE WITH 54/74LS590
