Philips Semiconductors
2.5V/3.3V 20-bit buffer/line driver, non-inverting,
with 30Ω termination resistors (3-State)
Product specification
74ALVT162827
FEATURES
• Multiple V_CC 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
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
and 200 V per Machine Model
• Bus hold data inputs eliminate the need for external pull-up
resistors to hold unused inputs
DESCRIPTION
The 74ALVT162827 high-performance BiCMOS device combines
low static and dynamic power dissipation with high speed and high
output drive. It is designed for V_CC 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.
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.
