HD74ALVCH16269 Description
The HD74ALVCH16269 is used in applications where two separate ports must be multiplexed onto, or demultiplexed from, a single port. The device is particularly suitable as an interface between synchronous DRAMs and high speed microprocessors. Data is stored in the internal B port registers on the low to high transition of the clock (CLK) input when the appropriate clock enable (CLKENA ) inputs are low.
HD74ALVCH16269 Key Features
- VCC = 2.3 V to 3.6 V
- Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C)
- Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C)
- High output current ±24 mA (@VCC = 3.0 V)
- Bus hold on data inputs eliminates the need for external pullup / pulldown resistors
