SN74LS158D集成电路（IC）的信号开关多路复用器解码器规格书PDF中文资料

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.
