74VHC541; 74VHCT541
Octal buffer/line driver; 3-state
Rev. 01 — 12 August 2009
Product data sheet
1. General description
The 74VHC541; 74VHCT541 are high-speed Si-gate CMOS devices.
The 74VHC541; 74VHCT541 are octal non-inverting buffer/line drivers with 3-state bus
compatible outputs.
The 3-state outputs are controlled by the output enable inputs OE0 and OE1.
A HIGH on OEn causes the outputs to assume a high-impedance OFF-state.
