SN74LS125A に関する概要
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.
