1 / 10 page ![]() M54HC240HV/241HV M74HC240HV/241HV April 1993 HC240HV: INVERTED - HC241HV NON INVERTED OCTAL BUS BUFFER WITH 3 STATE OUTPUTS B1R (Plastic Package) ORDER CODES : M54HCXXXHVF1R M74HCXXXHVM1R M74HCXXXHVB1R F1R (Ceramic Package) M1R (Micro Package) PIN CONNECTION (top view) . HIGH SPEED tPD = 12 ns (TYP.) at VCC =5V . LOW POWER DISSIPATION ICC =4 µA (MAX.) at TA =25 oC . HIGH NOISE IMMUNITY VNIH =VINL =28 % VCC (MIN.) . OUTPUT DRIVE CAPABILITY 15 LSTTL LOADS . SYMMETRICAL OUTPUT IMPEDANCE |IOH|= IOL = 6 mA (MIN) . BALANCED PROPAGATION DELAYS tPLH =tPHL . SAME FUNCTION OF HC240/241 PLUS HIGH TO LOW LEVEL LOGIC CONVERSION CAPA- BILITY . LATCH UP FREE OPERATION ALSO WHEN VIH IS HIGHER THAN VCC DESCRIPTION The M54/74HC240HV and HC241HV are high speed CMOS OCTAL BUS BUFFERs fabricated in silicon gate C 2MOS technology. They have the same high speed performance of LSTTL combined with true CMOS low power consumption. Performing the same function of their non HV counterpart, they have a particularl input configuration which allows all inputs to be driven by logic levels exceeding the supply voltage. This makes them particularly suitable in systems where mixed 3V/5V logic devices need to be interfaced. All inputs are equipped with protection circuits against static discharge and transient excess voltage. NOTE: BOTH DEVICES DO NOT MEET 2KV ESD RATING HC241HV HC240HV 1/10 |
