SN74HCS237数据手册集成电路（IC）的信号开关多路复用器解码器规格书PDF

描述 Description

The SN74HCS237 is a three to eight decoder with latched address inputs, one standard output strobe (G0), and one active low output strobe (G 1). When the latch enable (LE) input is low, the device acts as a standard three to eight decoder. When the latch enable (LE) input is high, the address latch retains its previous state. When the outputs are gated by either strobe input, they are all forced into the low state. When the outputs are not disabled by one or both of the strobe inputs, only the selected output is high while all others are low.
