74LVT2244 3.3 V octal buffer/line drive r with 30  termination resistors; 3- state Rev. 3 — 1 September 2016 Pro duct data sheet 1. General description The 74LVT2244 is a high-performance B iCMOS product designed for VCC operatio n at 3.3 V. This device is an octal buf fer that is ideal for driving bus lines . The device features two output enable s (1OE, 2OE), each controlling four of the 3-state outputs. The 74LVT2244 is d esigned with 30  series resistance i n both the HIGH and LOW states of the o utput. This design reduces line noise i n applications such as memory address d rivers, clock drivers, and bus receiver s/transmitters. 2. Features an
