Frequently Asked Questions
What clock frequency can 74AHC16374DGVRE4 handle, and which bus speeds does that support?
74AHC16374DGVRE4 is rated for clock frequencies up to 75 MHz at a 5 V supply. This is fast enough to register 16-bit data on ISA-class parallel buses, FPGA configuration interfaces, and 50 MHz peripheral buses, making it a reliable pipeline register between microcontrollers and high-speed memory or I/O expansion devices.
How does the 3-state output feature of 74AHC16374DGVRE4 benefit shared bus designs?
The 3-state outputs allow 74AHC16374DGVRE4 to disconnect all 16 output lines simultaneously when the output-enable pin is deasserted, presenting a high-impedance state to the bus. This lets multiple devices share the same 16-bit bus without contention, a critical requirement in systems with 8 mA bus drivers and multiple bus masters or memory-mapped peripherals.
What output drive strength does 74AHC16374DGVRE4 provide, and how many 50 pF loads can it handle?
Each output pin sources or sinks 8 mA at 3.3 V or 5 V supply, and the device is characterized at 50 pF load capacitance per output. This drive strength supports bus lines with several PCB traces and connector pins attached, without requiring additional buffer stages in typical backplane or multi-board interconnect designs.
Over what temperature range does 74AHC16374DGVRE4 operate, and what does E4 qualification mean?
The device operates from -40°C to +125°C, which covers the full automotive and industrial temperature range. The E4 suffix denotes AEC-Q100 compatible qualification and Pb-free processing, confirming the component meets automotive OEM requirements for reliability screening, moisture sensitivity, and halogen-free packaging.
How does 74AHC16374DGVRE4 compare to 74HC374 in a 3.3 V FPGA interface design?
74AHC16374DGVRE4 integrates 16 flip-flops in a single TSSOP-48 package whereas 74HC374 provides only 8 bits in a 20-pin package, so two 74HC374 devices would be needed for the same width. Additionally, the AHC family operates down to 2 V versus 2 V minimum for HC, and delivers faster propagation delays below 5 ns at 3.3 V, improving timing margins at 75 MHz.
