2.5V/3.3V 1-to-4 address driver with 30

Ω

termination resistors (3-State)

1998 Jun 30

853-2089 19651

FEATURES

• Multiple V

CC and GND pins minimize switching noise

• 5V I/O Compatible

• Live insertion/extraction permitted

• 3-State output buffers

• Power-up 3-State

• Output capability: +12mA/-12mA

• Latch-up protection exceeds 500mA per Jedec JC40.2 Std 17

• ESD protection exceeds 2000 V per MIL STD 883 Method 3015

and 200 V per Machine Model

• Outputs include series resistance of 30Ω making external

termination resistors unnecessary

DESCRIPTION

The 74ALVT162344 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 74ALVT162344 is a 1-to-4 address driver used in applications

where four separate memory locations must be addressed by a

single address.

The 74ALVT162344 is designed with 30

Ω 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.
