Philips Electronics 

Philips Semiconductors Low Voltage Products

3.3V ABT 16-bit buffer/driver (3-State)

Preliminary specification

74LVT16541A

FEATURES

• 16-bit universal 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 JC40.2 Std 17

• ESD protection exceeds 2000V per MIL

STD 883 Method 3015 and 200V per

Machine Model

DESCRIPTION

The LVT16541A is a high-performance

BiCMOS product designed for VCC operation

at 3.3V.

This device can be used as two octal buffers

or one 16-bit buffer. The device is ideal for

driving bus lines.
