74LVT240 74LVTH240
Low Voltage Octal Buffer/Line Driver
with 3-STATE Outputs
General Description
The LVT240 and LVTH240 are inverting octal buffers and
line drivers designed to be employed as memory address
drivers, clock drivers and bus oriented transmitters or
receivers which provides improved PC board density.
The LVTH240 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) V
CC
applications, but with the capability to
provide a TTL interface to a 5V environment. The LVT240
and LVTH240 are fabricated with an advanced BiCMOS
technology to achieve high speed operation similar to 5V
ABT while maintaining low power dissipation.
Features
a73 Input and output interface capability to systems at
5V V
CC
a73 Bushold data inputs eliminate the need for external
pull-up resistors to hold unused inputs (74LVTH240),
also available without bushold feature (74LVT240)
a73 Live insertion/extraction permitted
a73 Power Up/Down high impedance provides glitch-free
bus loading
a73 Outputs source/sink c1632 mA/c1464 mA
a73 Functionally compatible with the 74 series 240
a73 Latch-up performance exceeds 500 mA
a73 ESD performance:
Human-body model c33 2000V
Machine model c33 200V
Charged-device model c33 1000V
