74LVT244A 74LVTH244A 3.3 V octal buffer/line driver 3-state Rev. 04 3 September 2008 Product data sheet 1. General description The 74LVT244A 74LVTH244A 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 enables (1OE, 2OE), each controlling four of the 3-state outputs. 2. Features n Octal bus interface n 3-state buffers 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 Live insertion and extraction permitted n Power-up 3-state n No bus current loading when output is tied to 5 V bus n Latch-up protection u JESD78 Class II exceeds 500 mA n ESD protection: u HBM JESD22-A114E exceeds 2000 V u MM JESD22-A115-A exceeds 200 V 3.
