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 flowthrough 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.
