1998 Feb 25 853-1772 19018
FEATURES
• 16-bit bidirectional bus interface
• Power-up 3-State
• Multiple V
CC
and GND pins minimize switching noise
• 3-State buffers
• Output capability: +12mA/–32mA
• Latch-up protection exceeds 500mA per JEDEC Std 17
• ESD protection exceeds 2000 V per MIL STD 883 Method 3015
and 200V per Machine Model
• Same part as 74ABT16245A-1
• 74ABTH162245A incorporates bus hold data inputs which
eliminate the need for external pull-up resistors to hold unused
inputs
• Bus-hold data inputs eliminate the need for external pull-up
resistors to hold unused inputs
DESCRIPTION
The 74ABT162245A high-performance BiCMOS device combines
low static and dynamic power dissipation with high speed.
The 74ABT162245A 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 two Output
Enable (1OE
, 2OE) inputs for easy cascading and two Direction
(1DIR, 2DIR) inputs for direction control.
The 74ABT162245A is designed with 30 ohm series resistance in
both the upper and lower output structures on both A and B ports.
This design reduces line noise in applications such as memory
address drivers, clock drivers, and bus receiver/transmitters.
The 74ABT162245A is the same as the 74ABT16245A-1. The part
number has been changed to reflect industry standards
Two options are available, 74ABT162245A which does not have the
bus hold feature and the 74ABTH162245A which incorporates the
bus hold feature.
