DESCRIPTION:
This 32-bit bus transceiver is built using advanced dual metal CMOS technology. This high-speed, low power transceiver is ideal for asynchronous munication between two busses (A and B). The Direction and Output Enable controls are designed to operate the device as either four independent 8-bit transceivers or one 32-bit transceiver. The direction control pins (DIR) control the direction of data flow. The output enable pins (OE) override the direction control and disable both ports. All inputs are designed with hysteresis for improved noise margin.
The ALVCH32245 has been designed with a ±24m A output driver. This driver is capable of driving a moderate to heavy load while maintaining speed performance.
The ALVCH32245 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 puting systems
