Frequently Asked Questions
What is the maximum clock frequency supported by the 74ABT162823ADLRG4?
The 74ABT162823ADLRG4 supports clock frequencies up to 150 MHz, making it suitable for high-speed digital bus interface applications where fast data transfer between system components is required.
What package type and pin count does the 74ABT162823ADLRG4 use?
The 74ABT162823ADLRG4 is housed in a 56-pin Small Outline Integrated Circuit (SOIC) package, also designated as R-PDSO-G56. This compact surface-mount package is suitable for automated PCB assembly and is available in tape and reel format.
What output drive capability does the 74ABT162823ADLRG4 provide, and what load capacitance is it rated for?
The 74ABT162823ADLRG4 provides a maximum output low current (IOL) of 12 mA, enabling it to drive heavy bus loads. It is rated for a load capacitance of 50 pF, which is typical for standard bus interface applications in high-speed digital systems.
Is the 74ABT162823ADLRG4 unidirectional or bidirectional, and how is its enable controlled?
The 74ABT162823ADLRG4 is a unidirectional 18-bit bus-interface flip-flop. Its output enable is controlled by an active-low enable signal, allowing the outputs to be placed in a high-impedance (3-state) condition when the device is not actively driving the bus, preventing bus conflicts in multi-driver environments.
