74LVT2244 • 74LVTH2244

Low Voltage Octal Buffer/Line Driver

with 3-STATE Outputs

and 25Ω Series Resistors in the Outputs

General Description

The LVT2244 and LVTH2244 are octal buffers and line

drivers designed to be employed as memory address driv-

ers, clock drivers and bus oriented transmitters or receivers

which provides improved PC board density. The equivalent

25Ω-Series resistors helps reduce output overshoot and

undershoot.

The LVTH2244 data inputs include bushold, eliminating the

need for external pull-up resistors to hold unused inputs.

These octal buffers and line drivers are designed for low-

voltage (3.3V) VCC applications, but with the capability to

provide a TTL interface to a 5V environment. The LVT2244

and LVTH2244 are fabricated with an advanced BiCMOS

technology to achieve high speed operation similar to 5V

ABT while maintaining low power dissipation.

Features

s Input and output interface capability to systems at

5V VCC

s Equivalent 25Ω-Series resistors on outputs

s Bushold data inputs eliminate the need for external

pull-up resistors to hold unused inputs (74LVTH2244),

also available without bushold feature (74LVT2244).

s Live insertion/extraction permitted

s Power Up/Down high impedance provides glitch-free

bus loading

s Outputs source/sink −12 mA/+12 mA

s Latch-up performance exceeds 500 mA

s ESD performance:

Human-body model > 2000V

Machine model > 200V

Charged-device model > 1000V
