Frequently Asked Questions
What output drive current does 74ALVCH16334DGVRE4 provide and how many bits does it drive simultaneously?
The 74ALVCH16334DGVRE4 drives 16 outputs simultaneously with up to 24 mA sink current per output. The 3-state outputs allow bus sharing with other devices, and the active-low output enable pin controls all 16 channels together. This 16-bit drive capability at 24 mA suits DDR memory address bus buffering and FPGA I/O fan-out at 3.3 V.
What supply voltage range does 74ALVCH16334DGVRE4 support, and is it compatible with mixed 2.5 V and 3.3 V systems?
The 74ALVCH16334DGVRE4 operates from a supply voltage range of 1.65 V to 3.6 V. This range makes it compatible with both 2.5 V and 3.3 V logic levels in mixed-voltage bus environments. Its input threshold levels accept signals from 1.8 V CMOS logic families, enabling level-transparent buffering without additional voltage translation circuitry.
For a 16-bit memory bus design requiring fast propagation, what propagation delay does 74ALVCH16334DGVRE4 achieve?
The 74ALVCH16334DGVRE4 achieves typical propagation delay of approximately 2.5 ns to 3.5 ns at 3.3 V supply driving 50 pF loads. This low propagation delay is sufficient for 100 MHz to 133 MHz memory bus applications. The ALVCH family's reduced swing outputs further lower switching noise on dense PCB layouts with 16 simultaneous outputs switching.
