4 — 17 May 2021 Product data sheet 1.
General description The 74LVT2244 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 nOE causes the outputs to assume a high-impedance OFF-state.
Bus hold data inputs eliminate the need for external pull-up resistors to define unused inputs The 74LVT2244 is designed with 30 Ω series resistance in both the HIGH and LOW states of the output.
This design reduces line noise in applications such as memory address drivers, clock drivers, and bus receivers/transmitters.
