What are the key features of SN74F86DG4?
- Quad 2-input XOR configuration provides 4 independent exclusive-OR gates in a single 14-pin SOIC package, reducing component count in parity and comparison circuits
- F/FAST family logic delivers approximately 5 ns typical propagation delay at 5V, enabling use in high-speed data processing and clock distribution paths
- 20mA output sink current and 50pF load drive capability supports direct connection to bus lines and multiple CMOS/TTL inputs without buffer stages
- 5V TTL-compatible I/O levels ensure seamless interfacing with legacy and modern 5V logic systems in industrial and communications equipment
What is SN74F86DG4 used for?
The SN74F86DG4 is used in digital systems for parity generation and checking, binary comparators, phase detectors, and programmable logic input conditioning where fast exclusive-OR operations are required at 5V supply. Its F-series speed makes it suitable for data-path logic in communications interface boards, FPGA glue-logic circuits, and test-and-measurement equipment operating at frequencies where slower 74HC or 74LS XOR gates introduce unacceptable delay.

Frequently Asked Questions
How fast is the SN74F86DG4, and which logic families does it outperform in propagation delay?
The SN74F86DG4 belongs to the F/FAST logic family with a typical propagation delay of approximately 5 ns at 5V and 50pF load, significantly faster than 74LS (10 ns) and 74HC (7 ns) XOR gates, making it the preferred choice for high-speed data-path and parity circuits operating above 50 MHz.
For a 4-bit parity checker design, can a single SN74F86DG4 provide a complete solution?
Yes. With 4 independent XOR gates in one 14-pin SOIC package, a single SN74F86DG4 can implement a 4-input parity tree by chaining the 4 gates: two first-stage gates XOR pairs of bits, and a third gate XORs those results, while the fourth gate is available for a second parity bit or additional logic at no extra cost.
What output drive current does the SN74F86DG4 provide, and how many standard TTL loads can it drive?
The device sinks up to 20mA (IOL) and sources up to 1mA (IOH), sufficient to drive 20 standard TTL unit loads or 40 LS-TTL loads simultaneously. This high sink current makes it suitable for driving indicator LEDs through a resistor or directly loading moderately capacitive bus lines without external buffers.
How does the 14-pin SOIC package of the SN74F86DG4 compare to its DIP counterpart for modern PCB designs?
The 14-pin SOIC (R-PDSO-G14) occupies approximately 8.65×3.9 mm, about 50% less board area than a through-hole DIP-14 (19.3×6.4 mm), and supports automated SMT assembly, making it the preferred package for contemporary high-density PCBs in industrial, telecom, and consumer electronics manufacturing.
