FEATURES
16-bit bidirectional bus interface Power-up 3-State Multiple VCC and GND pins minimize switching noise 3-State buffers Output capability: +64 mA/–32mA Latch–up protection exceeds 500mA per JEDEC Std 17 Live insertion/extraction permitted ESD protection exceeds 2000 V per MIL STD 883 Method 3015
and 200V per Machine Model 74ABTH16245B 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 74ABT16245B high-performance BiCMOS device combines
low static and dynamic power dissipation with high speed and high
output drive.
The 74ABT16245B device is a dual octal 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.
Two options are available, 74ABT16245B which does not have the
bus hold feature and the 74ABTH16245B which incorporates the
bus hold feature.

FUNCTION TABLE
= High voltage level = Low voltage level = Don’t care = High impedance “off” scale
ABSOLUTE MAXIMUM RATINGS1, 2
NOTES:
Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

DC ELECTRICAL CHARACTERISTICS
NOTES:
Not more than one output should be tested at a time, and the duration of the test should not exceed one second. This is the increase in supply current for each input at 3.4V. This is the bus hold overdrive current required to force the input to the opposite logic state.
