Product Summary

The SN74HC125D is a quadruple bus buffer gate with 3-state outputs. The SN74HC125D features independent line drivers with 3-state outputs. Each output is disabled when the associated output-enable (OE) input is high. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

Parametrics

SN74HC125D absolute maximum ratings: (1)Supply voltage range, VCC: -0.5V to 7V; (2)Input clamp current, IIK (VI<0 or VI>VCC): ±20mA; (3)Output clamp current, IOK (VO<0 or VO>VCC): ±20mA; (4)Continuous output current, IO (VO = 0 to VCC): ±35mA; (5)Continuous current through VCC or GND: ±70mA; (6)Package thermal impedance, θJA: 86℃/W; (7)Storage temperature range, Tstg: -65℃ to 150℃.
