IDT74ALVCH32244
3.3V CMOS 32-BIT
BUFFER/ DRIVER WITH
3-STATE OUTPUTS AND
BUS-HOLD
DESCRIPTION:
This 32-bit buffer/driver is built using advanced dual metal CMOS
technology. This high-speed, low power device offers bus/backplane
interface capability with improved packing density. The device has a flow-
through organization for simplifying board layout. The three-state controls
operate this device in a Quad-Nibble, Dual-Byte or single 16-bit word mode.
All inputs are designed with hysteresis for improved noise margin.
The ALVCH32244 has been designed with a ±24mA output driver. This
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
The ALVCH32244 has “bus-hold” which retains the inputs’ last state
whenever the input bus goes to a high impedance. This prevents floating
inputs and eliminates the need for pull-up/down resistors.
APPLICATIONS:
• 3.3V high speed systems
• 3.3V and lower voltage computing systems
