74ALVT16240

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 VCC operation at 2.5 V or 3.3 V with I/O compatibility up to 5 V. w w w . D a t a S h e e t 4 U . c o mThe 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.
