They have the same high speed performance of LSTTL combined with true CMOS low power consumption. The HC266 has a high performance N-channel MOS transistor (OPEN DRAIN output). The HC7266 has an output buffer which is CMOS structure. Input and output buffers ensure high noise immunity and stable outputs. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
