74LVT162240 • 74LVTH162240
Low Voltage 16-Bit Inverting Buffer/Line Driver
with 3-STATE Outputs and
25Ω Series Resistors in the Outputs
General Description
Features
■ Input and output interface capability to systems at
The LVT162240 and LVTH162240 contain sixteen inverting
buffers with 3-STATE outputs designed to be employed as
a memory and address driver, clock driver, or bus oriented
transmitter/receiver. The device is nibble controlled. Indi-
vidual 3-STATE control inputs can be shorted together for
8-bit or 16-bit operation.
5V VCC
■ Outputs include equivalent series resistance of 25Ω to
make external termination resistors unnecessary and
reduce overshoot and undershoot
■ Bushold data inputs eliminate the need for external
pull-up resistors to hold unused inputs (74LVTH162240),
also available without bushold feature (74LVT162240).
The LVT162240 and LVTH162240 are designed with
equivalent 25Ω series resistance in both the HIGH and
LOW states of the output. This design reduces line noise in
applications such as memory address drivers, clock driv-
ers, and bus transceivers/transmitters.
■ Live insertion/extraction permitted
■ Power Up/Down high impedance provides glitch-free
bus loading
The LVTH162240 data inputs include bushold, eliminating
the need for external pull-up resistors to hold unused
inputs.
■ Functionally compatible with the 74 series 162240
■ Latch-up performance exceeds 500 mA
■ ESD performance:
These inverting buffers and line drivers are designed for
low-voltage (3.3V) VCC applications, but with the capability
Human-body model > 2000V
to provide a TTL interface to a 5V environment. The
LVT162240 and LVTH162240 are fabricated with an
advanced BiCMOS technology to achieve high speed oper-
ation similar to 5V ABT while maintaining a low power dis-
sipation.
