74AHC2G126; 74AHCT2G126 Dual buffer/line driver; 3-state Rev. 02 — 21 September 2004 Product data sheet 1. General description The 74AHC2G126; AHCT2G126 is a high-speed Si-gate CMOS device. The 74AHC2G126; AHCT2G126 provides a dual non-inverting buffer/line driver with 3-state output. The 3-state output is controlled by the output enable input (OE). A LOW at pin nOE causes the output to assume a high-impedance OFF-state. 2. Features ■ Symmetrical output impedance ■ High noise immunity ■ ESD protection: ◆ HBM EIA/JESD22-A114-B exceeds 2000 V ◆ MM EIA/JESD22-A115-A exceeds 200 V ◆ CDM EIA/JESD22-C101 exceeds 1000 V. ■ Low power dissipation ■ Balanced propagation delays ■ Multiple package options ■ Specified from −40 °C to +85 °C and from −40 °C to +125 °C. 3.
