74LS158中文资料摩托罗拉数据手册PDF规格书

The LSTTL/MSI SN54L/74LS158 is a high speed Quad 2-input Multiplexer. It selects four bits of data from two sources using the common Select and Enable inputs. The four buffered outputs present the selected data in the inverted form. The LS158 can also generate any four of the 16 different functions of two variables. The LS158 is fabricated with the Schottky barrier diode process for high speed and is completely compatible with all Motorola TTL families.
