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.
