HD74ALVCHR162269A
12-bit to 24-bit Registered Bus Exchanger with 3-state Outputs
ADE-205-125 (Z) Preliminary 1st.
Edition January 1998 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.
It is particularly suitable as an interface between synchronous DRAMs and high speed microprocessors.
The HD74ALVCHR162269A is designed specifically for low
voltage (from 2.
5 V to 3.
3 V) VCC operation.
Data is stored in the internal B-port registers on the low to high transition of the CLK input, provided that the appropriate CLKENA inputs are low.
