Frequently Asked Questions
What is the maximum clock frequency supported by the SN74LVTH273DBRG4 under nominal supply conditions?
The SN74LVTH273DBRG4 supports up to 150 MHz maximum clock frequency at nominal supply voltage, measured with a 50 pF load capacitance. This makes it suitable for high-speed bus latching in FPGA peripheral interfaces and DSP data pipelines where cycle times are below 7 ns.
How much output sink current can the SN74LVTH273DBRG4 provide, and what does that enable in circuit design?
The device provides a maximum low-level output current (IOL) of 64 mA across its 8 output pins. This 64 mA drive capability allows direct connection to bus lines or even LED indicators without needing additional buffer stages, reducing component count and board complexity.
Which package does the SN74LVTH273DBRG4 use, and how does it compare to a standard SOP in board density?
The G4 suffix part uses a 20-pin SSOP (shrink small outline package) with a narrower pitch than standard SOP-20, reducing footprint width to approximately 5.3 mm versus 7.5 mm for wide-body SOP. This smaller footprint enables tighter placement in multi-register arrays on density-critical PCBs.
Is SN74LVTH273DBRG4 a suitable alternative to 5 V logic flip-flops in a mixed 3.3 V / 5 V system?
Yes. The LVT family is designed for 3.3 V operation while tolerating 5 V logic inputs, making SN74LVTH273DBRG4 an appropriate drop-in replacement for 5 V ABT or AHCT 273 devices in mixed-voltage systems. The 150 MHz speed rating also exceeds typical 74HCT273 performance, providing a meaningful upgrade path.
