FEATURES

• 16-bit bus interface

• 3-State buffers

• Output capability: +64mA/-32mA

• TTL input and output switching levels

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

• Bus-hold data inputs eliminate the need for external pull-up

resistors to hold unused inputs

• Live insertion/extraction permitted

• Power-up 3-State

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

• Latch-up protection exceeds 500mA per JEDEC Std 17

• ESD protection exceeds 2000V per MIL STD 883 Method 3015

and 200V per Machine Model

DESCRIPTION

The 74LVT16244B is a high-performance BiCMOS product

designed for VCC operation at 3.3V.

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.
