1998 Feb 19

853-1745 18991

FEATURES

• Octal 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

• Power-up 3-State

• Live insertion/extraction permitted

• 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 LVT244A is a high-performance BiCMOS product designed for

VCC operation at 3.3V.

This device is an octal buffer that is ideal for driving bus lines. The

device features two Output Enables (OE1, OE2), each controlling

four of the 3-State outputs.
