74ALVT16240 16-bit inverting buffer/driver; 3-state Rev. 03 4 July 2005 Product data sheet 1. General description The 74ALVT16240 is a high-performance BiCMOS device designed for V operation at CC 2.5 V or 3.3 V with I/O compatibility up to 5 V. The 74ALVT16240 is an inverting 16-bit buffer that is ideal for driving bus lines. The device features four output enable inputs (1OE, 2OE, 3OE, 4OE), each controlling four of the 3-state outputs. 2. Features 5 V I/O compatible Live insertion and extraction permitted 3-state buffers Power-up 3-state Output capability: +64 mA and - 32 mA Latch-up protection: JESD 78 exceeds 500 mA Electrostatic discharge protection: MIL STD 883 method 3015: exceeds 2000 V Machine model: exceeds 200 V Bus hold data inputs eliminate need for external pull-up resistors to hold unused inputs 16-bit bus interface TTL input and output switching levels Input and output interface capability to systems at 5 V supply No bus current loading when output is tied to 5 V bus 3.
