74LVT2244 3.3 V octal buffer/line driver with 30  termination resistors; 3-state Rev. 3 — 1 September 2016 Product data sheet 1. General description The 74LVT2244 is a high-performance BiCMOS product designed for VCC operation at 3.3 V. This device is an octal buffer that is ideal for driving bus lines. The device features two output enables (1OE, 2OE), each controlling four of the 3-state outputs. The 74LVT2244 is designed with 30  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. 2.
