SN54HC540中文资料具有三态输出的军用 8 通道、2V 至 6V 反相器数据手册TI规格书

描述 Description

These octal buffers and line drivers feature the performance of the popular ’HC240 series and offer a pinout with inputs and outputs on opposite sides of the package. This arrangement greatly facilitates printed circuit board layout.

The 3-state control gate is a 2-input NOR. If either output-enable (OE1\\ or OE2\\) input is high, all eight outputs are in the high-impedance state. The ’HC540 devices provide inverted data at the outputs.
