Description
The HD74ALVCHR162269A is a 12-bit to 24-bit registered bus exchanger, which is intended for applications where two separate ports must be multiplexed onto, or de-multiplexed from, a single port.
Features
- All outputs have equivalent 26 Ω series resistors, so no external resistors are required.
- Bus hold on data inputs eliminates the need for external pullup / pulldown resistors. HD74ALVCHR162269A
