74AHC2G241; 74AHCT2G241
Dual buffer/line driver; 3-state
Rev. 02 — 13 January 2009
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.
