概要

The 74FCT164245T 16-bit high-speed, low-power 3.3V to 5V translator is designed to interface between a 3.3V bus and a 5V bus in a mixed 3.3V/5V supply environment. This enables system designers to interface TTL-compatible 3.3V components with 5V components. The Direction and Output Enable controls operate these devices as either two independent 8-bit transceivers or one 16-bit transceiver. The 74FCT164245T is ideally suited for driving high-capacitance loads and low-impedance backplanes. The 74FCT164245T operates at -40 °C to +85 °C.

74FCT164245T - Block Diagram
  • Bidirectional interface between 3.3V and 5V buses
  • Control inputs can be driven from either 3.3V or 5V circuits
  • ESD > 2000V per MIL-STD-883, Method 3015
  • > 200V using machine model (C = 200pF, R = 0)
  • VCC1 = 5V ±10%, VCC2 = 2.7V to 3.6V
  • High drive outputs (-32mA IOH, 64mA IOL) on 5V port
  • Power off disable on both ports permits "live insertion"
  • Typical VOLP (Output Ground Bounce) < 0.9V at VCC1 = 5V, VCC2 = 3.3V, TA = 25 °C
  • Available in 48-pin SSOP and TSSOP packages

    Parametric Table tips

    Tips for Using This Parametric Table:

    • Hide Filters button in header: Collapse or expands filters
    • Column sort buttons in header: Sort Column alphabetically / numerically descending or ascending
    • Reset button in header: Reset all filters to the page default
    • Full Screen button in header: Expand the table to full screen view (user must close out of full screen before they can interact with rest of page)
    • Export button in header: Export the filtered results of the table to an Excel document
    • Filter parts search bar in header: Type to filter table results by part number
    • Hide column button in column headers: Select to hide columns in table
    • AND / OR toggle switches in header: Toggles the logic of this particular filter to be “AND” or “OR” logic for filtering results
    • Multiselect checkboxes at beginning of each row in table: Select these checkboxes to compare products against each other
