DESCRIPTION:
CMOS technology. The LVCH16244A is designed specifically to improve
the performance and density of 3-state memory address drivers, clock
drivers, and bus-oriented receivers and transmitters. The device can be
used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. This device
provides true outputs and symmetrical active-low output-enable (OE)
inputs.
devices. This feature allows the use of this device a translator in a mixed
3.3V/5V supply system.
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
whenever the input goes to a high impedance. This prevents floating inputs
and eliminates the need for pull-up/down resistors.
The LVCH16244A 16-bit buffer/driver is built using advanced dual metal
All pins of this 16-bit buffer/driver can be driven from either 3.3V or 5V
The LVCH16244A has been designed with a ±24mA output driver. The
The LVCH16244A has “bus-hold” which retains the inputs’ last state
