SN74AHCT126-Q1 QUADRUPLE BUS BUFFER GATE WITH 3-STATE OUTPUTS SCLS506B − JUNE 2003 − REVISED FEBRUARY 2008 D Qualified for Automotive Applications D ESD Protection Exceeds 2000 V Per D D OR PW PACKAGE (TOP VIEW) MIL-STD-883, Method 3015; Exceeds 200 V Using Machine Model (C = 200 pF, R = 0) Inputs Are TTL-Voltage Compatible 1OE 1A 1Y 2OE 2A 2Y GND description The SN74AHCT126 device is a quadruple bus buffer gate featuring independent line drivers with 3-state outputs. Each output is disabled when the associated output-enable (OE) input is low. When OE is high, the respective gate passes the data from the A input to its Y output. 1 14 2 13 3 12 4 11 5 10 6 9 7 8 VCC 4OE 4A 4Y 3OE 3A 3Y To ensure the high-impedance state during power up or power down, OE should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.
