74LVT244B; 74LVTH244B 3.3 V octal buffer/line driver; 3-state Rev. 03 3 March 2006 Product data sheet 1. General description The 74LVT244B; 74LVTH244B is a high-performance BiCMOS product designed for V CC operation at 3.3 V. This device is an octal buffer that is ideal for driving bus lines. The device features two output enable inputs (1OE and 2OE), each controlling four of the 3-state outputs. 2. Features n Octal bus interface n 3-state buffers n Speed upgrade of 74LVT244A n Output capability: +64 mA and - 32 mA n TTL input and output switching levels n Input and output interface capability to systems at 5 V supply n Bus hold data inputs eliminate need for external pull-up resistors to hold unused inputs n Power-up 3-state n Live insertion and extraction permitted n No bus current loading when output is tied to 5 V bus n Latch-up protection: u JESD78: exceeds 500 mA n ESD protection: u HBM EIA/JESD22-A114-C exceeds 2000 V u MM EIA/JESD22-A115-A 200 V 3.
