DESCRIPTION

The HC690/691/692/693 are high speed CMOS COUNTER/REGISTER fabricated in silicon gate C2MOS technology.

They have the same high speed performance of LSTTL combined with true CMOS low power consumption.

■ HIGH SPEED fMAX = 50 MHz (TYP.) at VCC = 5 V

■ LOW POWER DISSIPATION ICC = 4 μA (MAX.) at TA = 25 °C

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

■ OUTPUT DRIVE CAPABILITY 15 LSTTL LOADS (for QA to QD) 10 LSTTL LOADS (for RCO)

■ SYMMETRICAL OUTPUT IMPEDANCE

|IOH| = IOL = 6 mA (MIN.) (for QA to QD)

|IOH| = IOL = 4 mA (MIN.) (for RCO)

■ BALANCED PROPAGATION DELAYS tPLH = tPHL

■ WIDE OPERATING VOLTAGE RANGE VCC (OPR) = 2 V to 6 V

■ PIN AND FUNCTION COMPATIBLE WITH LSTTL 54/74LS690/691
