74VHC126; 74VHCT126

Quad buffer/line driver; 3-state

The 74VHC126; 74VHCT126 are high-speed Si-gate CMOS devices and are pin compatible with Low-power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard No. 7-A.

The 74VHC126; 74VHCT126 provide four non-inverting buffer/line drivers with 3-state outputs. The 3-state outputs (nY) are controlled by the output enable input (nOE). A LOW-level at pin nOE causes the outputs to assume a high-impedance OFF-state.

The 74VHC126; 74VHCT126 are identical to the 74VHC125; 74VHCT125 but have active HIGH output enable inputs.

Features and benefits

  • Balanced propagation delays

  • All inputs have Schmitt-trigger action

  • Inputs accept voltages higher than VCC

  • Input levels:

    • The 74VHC126 operates with CMOS input level

    • The 74VHCT126 operates with TTL input level

  • ESD protection:

    • HBM JESD22-A114E exceeds 2000 V

    • MM JESD22-A115-A exceeds 200 V

    • CDM JESD22-C101C exceeds 1000 V

  • Multiple package options

  • Specified from -40 °C to +85 °C and from -40 °C to +125 °C
