SN74LS125A 的说明
These bus buffers feature three-state outputs that, when enabled, have the low impedance characteristics of a TTL output with additional drive capability at high logic levels to permit driving heavily loaded bus lines without external pullup resistors. When disabled, both output transistors are turned off, presenting a high-impedance state to the bus so the output will act neither as a significant load nor as a driver. The 125 and LS125A devices outputs are disabled when G\ is high. The 126 and LS126A devices outputs are disabled when G is low.
