74VHCT244BQ数据手册集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF

描述 Description

The 74VHC244; 74VHCT244 are a high-speed Si-gate CMOS devices.
The 74VHC244; 74VHCT244 have octal non-inverting buffer/line drivers with 3-state outputs. The 3-state outputs are controlled by the output enable inputs (nOE). A HIGH on nOE causes the outputs to assume a high-impedance OFF-state.
