MM54HC280/MM74HC280 9-Bit Odd/Even Parity Generator/Checker General Description Features The MM54HC280/MM74HC280 utilizes advanced silicongate CMOS technology to achieve the high noise immunity and low power consumption of standard CMOS integrated circuits. It possesses the ability to drive 10 LS-TTL loads. This parity generator/checker features odd/even outputs to facilitate operation of either odd or even parity applications. The word length capability is easily expanded by cascading devices. The 54HC/74HC logic family is speed, function, and pinout compatible with the standard 54LS/74LS family. All inputs are protected from damage due to static discharge by internal diode clamps to VCC and ground.

Note 4: For a power supply of 5V g 10% the worst case output voltages (VOH, and VOL) occur for HC at 4.5V. Thus the 4.5V values should be used when designing with this supply. Worst case VIH and VIL occur at VCC e 5.5V and 4.5V respectively. (The VIH value at 5.5V is 3.85V.) The worst case leakage current (IIN, ICC, and IOZ) occur for CMOS at the higher voltage and so the 6.0V values should be used. **VIL limits are currently tested at 20% of VCC. The above VIL specification (30% of VCC) will be implemented no later than Q1, CY’89. 2 AC Electrical Characteristics VCC e 5V, TA e 25§ C, CL e 15 pF, tr e tf e 6 ns Typ Guaranteed Limit Units Maximum Propagation Delay, Data to R Even 28 35 ns Maximum Propagation Delay, Data to R Odd 28 35 ns Symbol Parameter tPHL, tPLH tPHL, tPLH Conditions AC Electrical Characteristics VCC e 2.0V to 6.0V, CL e 50 pF, tr e tf e 6 ns (unless otherwise specified) Symbol Parameter Conditions TA e 25§ C VCC Typ 74HC TA eb40 to 85§ C 54HC TA eb55 to 125§ C Units Guaranteed Limits tPHL, tPLH Maximum Propagation Delay, Data to R Even 2.0V 4.5V 6.0V 103 21 17 205 41 35 258 52 44 305 61 52 ns ns ns tPHL, tPLH Maximum Propagation Delay, Data to R Odd 2.0V 4.5V 6.0V 103 21 17 205 41 35 258 52 44 305 61 52 ns ns ns tTLH, tTHL Maximum Output Rise and Fall Time 2.0V 4.5V 6.0V 30 8 7 75 15 13 95 19 16 110 22 19 ns ns ns CPD Power Dissipation Capacitance (Note 5) 83 CIN Maximum Input Capacitance 5 pF 10 10 10 pF Note 5: CPD determines the no load dynamic power consumption, PD e CPD VCC2 f a ICC VCC, and the no load dynamic current consumption, IS e CPD VCC f a ICC.
