CD74HCT154中文资料高速 CMOS 逻辑 4 至 16 线路解码器/多路解复用器数据手册TI规格书

描述 Description

The ’HC154 and ’HCT154 are 4-to-16 line decoders/demultiplexers with two enable inputs, E1 and E2. A High on either enable input forces the output into the High state. The demultiplexing function is performed by using the four input lines, A0 to A3, to select the output lines Y0\\ to Y15\\, and using one enable as the data input while holding the other enable low.

特性 Features

• Two Enable Inputs to Facilitate Demultiplexing and Cascading Functions
• Bus Driver Outputs. . . 15 LSTTL Loads
• Balanced Propagation Delay and Transition Times
• HC Types
• High Noise Immunity: NIL= 30%, NIH = 30% of VCC at VCC = 5V
• Direct LSTTL Input Logic Compatibility, VIL = 0.8V (Max), VIH = 2V (Min)
• CMOS Input Compatibility, Il 1µA at VOL, VOH
