1. General description

The 74LVT2241 is an 8-bit buffer/line driver with 3-state outputs. The device can be used as two

4-bit buffers or one 8-bit buffer. The device features two output enables (1OE and 2OE), each

controlling four of the 3-state outputs. A HIGH on 1OE or a LOW on 2OE causes the associated

outputs to assume a high-impedance OFF-state. Bus hold data inputs eliminate the need for

external pull-up resistors to define unused inputs.
