They have the same high speed performance of LSTTL combined with true CMOS low power consumption. These IC’s are composed of an independent 2channel multiplexer with common SELECT and ENABLE INPUT. The M54/74HC258 is an inverting multiplexer while the M54/74HC257 is a non-inverting multiplexer. When the ENABLE INPUT is held ”High”, outputs of both IC’s become high-impedance state. If SELECT INPUT is held ”Low”, ”A” data is selected, when SELECT INPUT is high ”H”, ”B” data is chosen. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
