74LVC126A - Quad Buffer

General Description

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.

Key Features

  • Wide Supply Voltage Range: 1.65V to 3.6V.
  • Inputs Accept Voltages up to 5.5V.
  • Propagation Delay: 3.3ns (TYP) at VCC = 3.3V.
  • Output Ground Bounce VOLP (TYP) < 0.8V at VCC = 3.3V and TA = +25℃.
  • Output VOH Undershoot VOHV (TYP) > 2V at VCC = 3.3V and TA = +25℃.
  • 3-State Output.
  • Separate OE for All 4 Buffers.
  • Latch-up Performance Exceeds 250mA.
  • -40℃ to +125℃ Operating Temperature Range.
  • Available in Green SOIC-14, TSSOP-14 and TQFN-3.5×3.5-14AL Packag.

74LVC126A Quad Buffer with 3-State Output GENERAL DESCRIPTION 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℃.
