Product Summary

The SN74LS125ADR is a quadruple bus buffer with 3-state outputs. It features three-state outputs that, when enabled, has 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, the SN74LS125ADR is 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 SN74LS125ADR’ outputs are disabled when G is high.
