IDT74ALVCH16863

NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
2. VCC terminals.
3. All terminals except VCC.

This 18-bit transceiver of the IDT74ALVCH16863 is built using advanced dual metal CMOS technology. The ALVCH16863 is a noninverting transceiver designed for asynchronous communication between data buses.

The control-function implementation minimizes external timing requirements. This high speed device can be used as two independent 9-bit transceivers or one 18-bit transceiver.

It allows data transmission of the IDT74ALVCH16863 from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the output-enable OEAB or OEBA) inputs. The ALVCH16863 has been designed with a ±24mA output driver. This driver is capable of driving a moderate to heavy load while maintaining speed performance.

The IDT74ALVCH16863 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
