The 74LVC126A that provides a quad buffer with 3-state output is designed for 1.65V to 3.6V VCC operation. Both 3.3V and 5V devices can drive inputs, enabling this device to operate as a translator in a mixed 3.3V and 5V system environment.
The 3-state outputs are controlled by the output enable input pin (nOE). When nOE is held low, all outputs are disabled. nOE should be connected to GND by using a pull-down resistor to ensure the high-impedance state in the period of power-up or power-down, and the minimum resistance depends on the current-sourcing capability of the driver.
The 74LVC126A is available in Green SOIC-14, TSSOP-14 and TQFN-3.5×3.5-14AL packages. It operates over an ambient temperature range of -40℃ to +125℃.
