Frequently Asked Questions
What is the maximum operating frequency of the SN74LV374APWE4?
The SN74LV374APWE4 has a maximum operating frequency of 50 MHz at nominal supply voltage. Combined with a load capacitance of 50 pF and an output sink current (IOL) of 12 mA, it is well suited for high-speed data bus and logic interfacing applications in embedded systems.
Does the SN74LV374APWE4 support three-state outputs?
Yes, the SN74LV374APWE4 features three-state outputs, allowing it to be used in bus-driving applications. When the output enable is deasserted, all eight outputs enter a high-impedance state, enabling multiple devices to share a common data bus without signal contention.
What package does the SN74LV374APWE4 use?
The SN74LV374APWE4 is housed in a 20-pin Thin Shrink Small Outline Package (TSSOP), identified by JESD-30 code R-PDSO-G20. This compact surface-mount package is ideal for density-critical PCB layouts in portable and space-constrained electronic designs.
Is the SN74LV374APWE4 RoHS compliant?
Yes, the SN74LV374APWE4 carries a JESD-609 code of e4, confirming full RoHS compliance and lead-free construction. It is suitable for modern lead-free soldering processes and meets international environmental standards for electronic components.
What are common replacements for the SN74LV374APWE4?
Common pin-compatible or functionally equivalent alternatives include the SN74LVTH374 (with bus-hold inputs), SN74LV374A in DIP or SOIC packages, and 74HC374 series devices from other manufacturers. Package and voltage range differences should be verified before substitution in existing designs.
