Rev. 03 — 4 July 2005

Product data sheet

1. General description

The 74ALVT16241 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.

The 74ALVT16241 is a 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

s 5 V I/O compatible

s Live insertion and extraction permitted

s 3-state buffers

s Power-up 3-state

s Output capability: +64 mA and −32 mA

s Latch-up protection:

x JESD 78 exceeds 500 mA

s Electrostatic discharge protection:

x MIL STD 883 method 3015: exceeds 2000 V

x Machine model: exceeds 200 V

s Bus hold data inputs eliminate need for external pull-up resistors to hold unused inputs

s 16-bit bus interface

s TTL input and output switching levels

s Input and output interface capability to systems at 5 V supply

s No bus current loading when output is tied to 5 V bus
