ICC = 4μA(MAX.) at TA=25°C HIGH NOISE IMMUNITY:NIH = VNIL = 28 % VCC (MIN.) SYMMETRICAL OUTPUT IMPEDANCE:OH | = IOL = 4mA (MIN) BALANCED PROPAGATION DELAYS: PLH ≅ t PHL WIDE OPERATING VOLTAGE RANGE:
VCC (OPR) = 2V to 6V PIN AND FUNCTION COMPATIBLE WITH
74 SERIES 688
DESCRIPTIONThe M74HC688 is an high speed CMOS 8 BIT
EQUALITY COMPARATOR fabricated with silicon
gate C2 MOS technology.
The M74HC688 compares bit for bit two 8-bit
words applied on inputs P0 - P7 and inputs Q0 -
Q7 and indicates whether or not they are equal. A
single active low enable is provided to facilitate
cascading several packages to enable
comparison of words greater than 8 bits.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.

CAPACITIVE CHARACTERISTICS 1) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without
load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC
TEST CIRCUIT CL = 50pF/150pF or equivalent (includes jig and probe capacitance)
RT = ZOUT of pulse generator (typically 50Ω)
