Product specification

74ALVT16245

FEATURES

• 16-bit bidirectional bus interface

• 5V I/O Compatible

• 3-State buffers

• Output capability: +64mA/–32mA

• TTL input and output switching levels

• 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 400V per Machine Model

DESCRIPTION

The 74ALVT16245 is a high-performance BiCMOS product

designed for VCC operation at 2.5V or 3.3V with I/O compatibility up

to 5V.

This device is a 16-bit transceiver featuring non-inverting 3-State

bus compatible outputs in both send and receive directions. The

control function implementation minimizes external timing

requirements. The device features an Output Enable (OE) input for

easy cascading and a Direction (DIR) input for direction control.
