74LVT244B; 74LVTH244B 3.3 V octal buffer/line driver; 3-state Rev. 6 — 12 August 2021 Product data sheet 1. General description The 74LVT244B; 74LVTH244B 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 2.
