DESCRIPTION
The M54/74HC592 is a high speed CMOS 8 BIT REGISTER COUNTER fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption.
The M54/74HC592 is a parallel input, 8 bit storage register feeding an 8 bit binary counter. Both the register and the counter have individual positive edge triggered clock. In addition, the counter has direct load and clear functions.Expansion is easily accomplished by connecting RCO af the first stage to the count enable of the second stage. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
■ HIGH SPEED fMAX = 35 MHz (TYP.) AT VCC = 5 V
■ LOW POWER DISSIPATION ICC = 4 µA (MAX.) AT TA = 25 °C
■ OUTPUT DRIVE CAPABILITY 10 LSTTL LOADS
■ BALANCED PROPAGATION DELAYS tPLH = tPHL
■ SYMMETRICAL OUTPUT IMPEDANCE IOL = IOH = 4 mA (MIN.)
■ HIGH NOISE IMMUNITY VNIH = VNIL = 28 % VCC (MIN.)
■ WIDE OPERATING VOLTAGE RANGE VCC (OPR) = 2 V TO 6 V
■ PIN AND FUNCTION COMPATIBLE WITH 54/74LS592
