74LVT16244B 74LVTH16244B 3.3 V 16-bit buffer/driver 3-state Rev. 08 22 March 2010 Product data sheet 1. General description The 74LVT16244B 74LVTH16244B is a high-performance BiCMOS product designed for V operation at 3.3 V. CC This device is a 16-bit buffer and line driver featuring non-inverting 3-state bus outputs. The device can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. 2. Features and benefits 16-bit bus interface 3-state buffers Output capability: +64 mA and 32 mA TTL input and output switching levels Input and output interface capability to systems at 5 V supply Bus hold data inputs eliminate need for external pull-up resistors to hold unused inputs Power-up 3-state Live insertion and extraction permitted No bus current loading when output is tied to 5 V bus Latch-up protection JESD78B Class II exceeds 500 mA ESD protection: HBM JESD22-A114F exceeds 2000 V MM JESD22-A115-A exceeds 200 V 3.
