4-Bit Magnitude Comparator
The TC74HC85A is a high speed CMOS 4 BIT MAGNITUDE
COMPARATOR fabricated with silicon gate C²MOS technology.
It achieves the high speed operation similar to equivalent
LSTTL while maintaining the CMOS low power dissipation.
The TC74HC85A compares tow 4-bit words applied to inputs
A0-A3 and B0-B3, and provides a high voltage level on one of
three outputs: A > B, A < B, or A = B.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
Features
• High speed: t_pd = 22 ns (typ.) at V_CC = 5 V
• Low power dissipation: I_CC = 4 μA (max) at Ta = 25°C
• High noise immunity: V_NIH = V_NIL = 28% V_CC (min)
• Output drive capability: 10 LSTTL loads
• Symmetrical output impedance: |I_OH| = I_OL = 4 mA (min)
• Balanced propagation delays: t_pLH ^∼− t_pHL
• Wide operating voltage range: V_CC (opr) = 2~6 V
• Pin and function compatible with 74LS85
