SN74ACT86DBR

Overview

The SN74ACT86DBR is a quad 2-input exclusive-OR gate manufactured by Texas Instruments. It belongs to the 74ACT logic series and utilizes CMOS technology. The device operates within a supply voltage range of 4.5 V to 5.5 V. It features a propagation delay of 9.5 ns at 5 V with a 50 pF load. Output drive capability is specified as 24 mA for both high and low states. The component is housed in a 14-TSSOP package and supports surface-mount installation.

Feature Summary

• Provides four independent exclusive-OR logic functions within a single integrated circuit
• Compatible with TTL input levels while utilizing CMOS output structures
• Supports standard surface-mount assembly techniques via TSSOP packaging

Applications

• Digital data path switching and signal routing
• Parity generation and error detection circuits
• Arithmetic logic unit (ALU) implementations

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints, particularly regarding the 14-TSSOP pinout dimensions. Confirm RoHS compliance status through current datasheets before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring 5 V operation with TTL-compatible inputs. The ACT series offers faster switching speeds compared to standard AC variants. Verify that the required output current capabilities align with downstream load requirements for reliable signal integrity.

Part Context

This part is a member of the Texas Instruments 74ACT family, which bridges the performance gap between older bipolar technologies and modern CMOS solutions. The SN74ACT86 variant specifically implements XOR functionality. It serves as a direct replacement for legacy 74LS86 designs in applications demanding lower power consumption and higher speed.
