74AHC2G241; 74AHCT2G241 Dual buffer/line driver; 3-state Rev. 01 — 10 March 2004 Product data sheet 1. General description The 74AHC2G241; 74AHCT2G241 is a high-speed Si-gate CMOS device. The 74AHC2G241; 74AHCT2G241 is a dual non-inverting buffer/line driver with 3-state outputs. The 3-state outputs are controlled by the output enable inputs 1OE and 2OE. A HIGH level at pin 1OE causes output 1Y to assume a high-impedance OFF-state. A LOW level at pin 2OE causes output 2Y to assume a high-impedance OFF-state. Schmitt-trigger action at all inputs makes the circuit highly tolerant for slower input rise and fall times. 2. Features ■ Symmetrical output impedance ■ High noise immunity ■ ESD protection: ◆ HBM EIA/JESD22-A114-A exceeds 2000 V ◆ MM EIA/JESD22-A115-A exceeds 200 V ◆ CDM EIA/JESD22-C101 exceeds 1000 V. ■ Low power dissipation ■ Balanced propagation delays ■ SOT505-2 and SOT765-1 package ■ Specified from −40 °C to +85 °C and from −40 °C to +125 °C. 3.
