What are the key features of SN74S86DE4?
- Quad 2-input XOR gate configuration provides 4 independent channels for bitwise comparison, parity generation, or phase detection in a single package
- 74S (Schottky TTL) family delivers fast switching speeds with propagation delays in the low nanosecond range for high-speed digital logic
- 20 mA output sink current (Iol) allows direct LED drive or bus driving without external buffer stages
What is SN74S86DE4 used for?
The SN74S86DE4 is used in digital communication systems and arithmetic logic units for parity checking, binary addition carry generation, and error detection circuits. Its quad XOR configuration suits hardware encryption circuits, phase comparison in PLL designs, and bitwise difference detection in digital test equipment. The 14-pin SOIC package and Schottky TTL compatibility make it a drop-in replacement in legacy 5 V TTL digital systems.

Frequently Asked Questions
How fast does the SN74S86DE4 switch, and is it fast enough for parity generation at 50 MHz data rates?
The SN74S86DE4 belongs to the 74S Schottky TTL family, which features propagation delay times typically around 7–8 ns at 5 V supply and 15 pF load. At 50 MHz data rates (20 ns bit period), this 7–8 ns delay still provides sufficient timing margin for single-stage parity generation, making SN74S86DE4 well-suited for error-detection logic in high-speed parallel data paths.
Can SN74S86DE4 replace a 74LS86 or 74HC86 in an existing 5 V TTL design?
The SN74S86DE4 is pin-compatible with 74LS86 and 74HC86 quad XOR gates in the standard 14-pin DIP or SOIC footprint. The 74S family has higher power consumption (~19 mW per gate) than 74LS (~2 mW) or 74HC CMOS, but offers faster switching with lower propagation delay of approximately 7 ns versus 10–15 ns for LS. For 5 V TTL-level systems prioritizing speed over power, the 74S86 is a direct functional substitute.
In a hardware AES key-mixing stage, how many SN74S86DE4 devices are needed to XOR two 8-bit bytes in parallel?
Each SN74S86DE4 contains 4 independent 2-input XOR gates. XOR-ing two 8-bit bytes requires 8 XOR operations, so 2 SN74S86DE4 ICs provide the full 8 channels in parallel. With the 14-pin SOIC-14 (R-PDSO-G14) package, two devices occupy roughly 20 mm² of PCB area, suitable for compact cryptographic preprocessing logic at 5 V supply.
