1 / 11 page  M54HC85 M74HC85 December 1992 4-BIT MAGNITUDE COMPARATOR B1R (Plastic Package) ORDER CODES : M54HC85F1R M74HC85M1R M74HC85B1R M74HC85C1R F1R (Ceramic Package) M1R (Micro Package) C1R (Chip Carrier) PIN CONNECTIONS (top view) NC = No Internal Connection INPUT AND OUTPUT EQUIVALENT CIRCUIT DESCRIPTION . HIGH SPEED tPD = 22 ns (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 10 LSTTL LOADS . SYMMETRICAL OUTPUT IMPEDANCE |IOH|= IOL = 4 mA (MIN.) . BALANCED PROPAGATION DELAYS tPLH =tPHL . WIDE OPERATING VOLTAGE RANGE VCC (OPR) = 2 V to 6 V . PIN AND FUNCTION COMPATIBLE WITH 54/74LS85 The M54/74HC85 is a high speed CMOS 4-BIT MAGNITUDE COMPARATOR fabricated in silicon gate C 2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption. This comparator compares two 4-bit words and provides a high volt- age level on one of the A > B out, A = B out and A < B out outputs. The comparing bit number is easily ex- panded by cascading several devices as shown in the typical application. All inputs are equipped with protection circuits against static discharge and tran- sient excess voltage. 1/11 |
