74AHC126 74AHCT126 Quad buffer/line driver 3-state Rev. 04 12 August 2009 Product data sheet 1. General description The 74AHC126 74AHCT126 is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL (LSTTL). It is specied in compliance with JEDEC standard No. 7-A. The 74AHC126 74AHCT126 provides 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 74AHC126 74AHCT126 is identical to the 74AHC125 74AHCT125 but has active HIGH output enable inputs. 2.
