IDT74LVCH16240A
DESCRIPTION:
This 16-bit buffer/driver is built using advanced dual metal CMOS
technology. This high-speed, low power device is designed specifically to
improve both the performance and density of 3-state memory address
drivers, clock drivers, and bus-oriented receivers and transmitters. The
devicecanbeusedasfour4-bitbuffers,two8-bitbuffers,orone16-bitbuffer.
This device provides inverting outputs and symmetrical active-low output-
enable (OE) inputs. To ensure the high-impedance state during power up
or power down, OE should be tied to Vcc through a pullup resistor; the
minimumvalueoftheresistorisdeterminedbythecurrent-sinkingcapability
of the driver.
All pins of this 16-bit buffer/line driver can be driven from either 3.3V or
5V devices. This feature allows the use of the device as a translator in a
mixed 3.3V/5V supply system.
The LVCH16240A has “bus-hold” which retains the inputs’ last state
whenever the input goes to a high impedance. This prevents floating inputs
and eliminates the need for pull-up/down resistors.
The LVCH16240A has been designed with a ±24mA output driver. The
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
