Key Features
- Four independent 2-input XOR gates in a single 14-pin DIP package, providing high integration for parity generation, comparators, and arithmetic logic functions in digital circuit designs
- Advanced CMOS AC-family speed with propagation delay under 7 ns at 5V supply, enabling high-frequency parity checking and bit comparison at clock rates exceeding 100 MHz
- 24mA output sink current (I_OL = 24mA) and 5.5V maximum supply support direct interfacing with TTL loads and 5V bus systems without external buffering
Applications
The CD74AC86E is widely used in parity generation and error-detection circuits for data communication interfaces, memory systems, and digital signal processing pipelines operating at up to 5.5V. Its quad 2-input XOR structure is ideal for building 4-bit or 8-bit parity trees, binary comparators, and arithmetic adder carry chains in embedded logic designs. The through-hole 14-pin DIP package makes it especially practical for prototyping, laboratory testing, and legacy industrial control board repairs where SMT assembly is not available.

Frequently Asked Questions
What is the output drive strength of CD74AC86E and how many TTL loads can it drive?
The CD74AC86E provides 24mA sink current (I_OL max) and 24mA source current per output at 5V, which is approximately 4 times stronger than standard 74HC-family XOR gates at 6mA. This allows each gate output to drive up to 8 standard TTL inputs or multiple CMOS gate inputs in parallel, making CD74AC86E suitable for bus-driving parity logic in 5V systems without additional buffer stages.
How fast is CD74AC86E and what clock frequency can parity circuits built with it support?
In the AC advanced CMOS family, the CD74AC86E achieves typical propagation delays of approximately 5 ns to 7 ns at 5V supply with 50pF load. This performance supports parity checking circuits operating at clock rates above 100 MHz, enabling real-time single-bit error detection in high-speed 8-bit and 16-bit data buses in FPGA interface designs and memory controllers.
When should engineers choose CD74AC86E over the CD74HCT86 or 74LS86 XOR gate?
Engineers should select CD74AC86E when higher output drive (24mA vs. 4mA for 74HCT86) or faster propagation delays are needed for demanding 5V designs. The AC family is also preferred over 74LS86 when lower quiescent power consumption is important, since CMOS technology consumes near-zero static current compared to TTL. However, 74HCT86 remains a better fit when direct TTL input threshold compatibility is the primary requirement.
What are typical circuit topologies that use multiple CD74AC86E gates for arithmetic functions?
Multiple CD74AC86E devices are cascaded in 2-level parity trees to generate even or odd parity across 8-bit or 16-bit data words, with each device contributing 4 XOR operations at sub-7 ns latency per stage. Two devices can also construct a full 4-bit binary comparator or implement the sum outputs of a 4-bit ripple-carry adder, combining with carry-lookahead circuits in TTL-compatible 5V ALU designs.
