Texas Instruments SN74LVC126A/SN74LVC126A-Q1 Buffer Gates

Texas Instruments SN74LVC126A/SN74LVC126A-Q1 Quadruple Bus Buffer Gates with 3-state outputs are designed to operate within the 1.65Vcc to 3.6Vcc voltage range. Each output is disabled when the associated Output-Enable (OE) input is low. The OE must be tied to GND through a pull-down resistor to ensure a high-impedance state during power down or up. The SN74LVC126A gates can be driven from 3.3V or 5V sources, allowing the user to use the devices as translators in a mixed 3.3V or 5V system environment. The SN74LVC126A-Q1 buffer gates are qualified for automotive applications. These buffer gates are used in AV receivers, portable audio docks, keyboards, wireless headsets, telecom, MP3 players, and recorders.
