Overview

DESCRIPTION

· The M74HC85 is a high-speed CMOS 4-bit magnitude comparator using silicon gate C2MOS technology.

· It compares two 4-bit words and outputs a high voltage level on one of the A>B, A=B, or A

· Cascading multiple devices allows for easy expansion of the comparing bit number.

· All inputs are protected against static discharge and transient excess voltage.

FEATURES
· High speed: Typical propagation delay (tPD) of 20 ns at VCC = 6V.
· Low power dissipation: Maximum ICC of 4 µA at TA = 25°C.
· High noise immunity: Minimum VNIH and VNIL of 28% VCC.
· Symmetrical output impedance: Minimum |IOH| and IOL of 4 mA.
· Balanced propagation delays: tPLH ≈ tPHL.
· Wide operating voltage range: VCC (OPR) from 2V to 6V.
· Pin and function compatible with the 74 series.

APPLICATIONS
· Suitable for use in digital systems requiring 4-bit magnitude comparison.
· Ideal for applications where high-speed operation and low power consumption are critical.
· Can be cascaded for larger bit comparison tasks.
· Compatible with 74 series logic devices for seamless integration.
