What are the key features of SN74F260DG4?

  • Dual 5-input NOR gate in F/FAST logic family delivering high-speed switching at 5 V for TTL-compatible bus logic
  • 20 mA output sink current per gate with 50 pF load capacitance specification for reliable fan-out in dense board logic
  • 14-pin SOIC package with RoHS e4 compliance, supporting space-efficient modern PCB layouts with standard SMT reflow assembly

What is SN74F260DG4 used for?

SN74F260DG4 is used in digital logic systems requiring fast 5-input NOR functions for address decoding, interrupt logic, and combinational control circuits. Its F/FAST family speed makes it appropriate for bus control and glue logic in microprocessor systems where propagation delay must be minimized. The dual-gate configuration allows two independent 5-input NOR functions in a single 14-pin SOIC, reducing component count on dense PCBs.

Frequently Asked Questions

How many inputs does each NOR gate in SN74F260DG4 support, and what logic family does it belong to?

Each of the 2 NOR gates in SN74F260DG4 accepts 5 inputs, enabling compact implementation of wide-input combinational logic. It belongs to the F/FAST logic family operating at 5 V, which offers significantly faster propagation delays than standard 74HC or 74LS equivalents, typically under 5 ns.

What output drive capability does SN74F260DG4 provide, and how does it affect fan-out?

SN74F260DG4 sinks up to 20 mA per output at a 5 V supply, providing sufficient drive to fan out to multiple TTL or FAST logic inputs on a bus. The specified load capacitance of 50 pF also ensures that timing characterizations remain valid when driving typical PCB trace capacitances in system designs.

In which address-decode applications can SN74F260DG4 replace a 74S260 or 74LS260?

SN74F260DG4 is a pin-compatible replacement for 74S260 and 74LS260 in address-decoding and chip-select circuits. Because its F/FAST propagation delay is shorter, it can satisfy tighter address setup times in 5 V microprocessor systems running at clock frequencies above 20 MHz, where older 74LS variants introduce excessive delay.

How does the 14-pin SOIC package of SN74F260DG4 simplify PCB assembly compared to DIP alternatives?

The 14-pin SOIC package has a lead pitch of 1.27 mm and a body width of approximately 3.9 mm, occupying far less PCB area than a 14-pin DIP and enabling automated SMT placement and reflow soldering. This reduces assembly cost and supports high-density board layouts where through-hole components are impractical.
