3.3V 16-bit transceiver (3-State)

1998 Feb 19

853-1753 18990

FEATURES

• 16-bit bidirectional 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 74LVT16245B is a high-performance BiCMOS product

designed for VCC operation at 3.3V.

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.
