FEATURES
74ALVT162827
DESCRIPTION
• Multiple VCC and GND pins minimize switching noise
• 5V I/O Compatible
• Live insertion/extraction permitted
• 3-State output buffers
• Outputs include series resistance of 30Ω making external
The 74ALVT162827 high-performance BiCMOS device combines
low static and dynamic power dissipation with high speed and high
output drive. It is designed for VCC operation at 2.5V or 3.3V with I/O
compatibility to 5V.
The 74ALVT162827 20-bit buffers provide high performance bus
interface buffering for wide data/address paths or buses carrying
parity. They have NOR Output Enables (nOE1, nOE2) for maximum
control flexibility.
termination resistors unnecessary
• Power-up 3-State
• Output capability: +12mA/–12mA
• Latch-up protection exceeds 500mA per Jedec Std 17
• ESD protection exceeds 2000 V per MIL STD 883 Method 3015
The 74ALVT162827 is designed with 30Ω series resistance in both
the pull-up and pull-down output structures. This design reduces line
noise in applications such as memory address drivers, clock drivers
and bus receivers/transmitters.
and 200 V per Machine Model
• Bus hold data inputs eliminate the need for external pull-up
resistors to hold unused inputs

NOTES:
1. 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.
2. 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.
3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

NOTES:
1. All typical values are at VCC = 3.3V and Tamb = 25°C.
2. This is the increase in supply current for each input at the specified voltage level other than VCC or GND
3. This parameter is valid for any VCC between 0V and 1.2V with a transition time of up to 10msec. From VCC = 1.2V to VCC = 3.3V ± 0.3V a
transition time of 100µsec is permitted. This parameter is valid for Tamb = 25°C only.
4. Unused pins at VCC or GND.
5. ICCZ is measured with outputs pulled up to VCC or pulled down to ground.
6. This is the bus hold overdrive current required to force the input to the opposite logic state.
