Overview
The SN74AHCT86BQAR is a quadruple 2-input exclusive-OR gate manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -40°C to +125°C. The device features TTL-compatible inputs, enabling effective voltage translation from 3.3 V to 5 V systems. It provides balanced output drive with low-level and high-level output currents of 8 mA each. The component utilizes a WQFN (BQA) package with 14 pins.
Feature Summary
- TTL-voltage compatible inputs allow for direct interfacing with legacy logic levels
- Low-drive CMOS architecture minimizes output ringing and overshoot on bus interfaces
- ESD protection exceeds JESD 22 standards for human-body and machine models
Applications
- Server infrastructure
- Network switches
- Wearable health and fitness devices
Procurement Notes
Verify the specific BQA package designation and RoHS compliance status against the latest manufacturer documentation before procurement. Confirm that the ordering suffix matches the required reel quantity and tape-and-reel specifications. Ensure the component meets the intended thermal and electrical requirements for the target application environment.
Selection Notes
Select this component when TTL compatibility is required for 3.3 V to 5 V translation in positive logic applications. The low-drive characteristics make it suitable for bus interface designs where minimizing signal ringing is critical. Verify that the operating temperature range and supply voltage constraints align with the system design parameters.
Part Context
This part belongs to the SNx4AHCT86 family of quadruple 2-input exclusive-OR gates. The 'SN' prefix indicates a commercial-grade device, while 'AHCT' specifies the advanced high-speed CMOS technology with TTL-compatible inputs. The 'BQAR' suffix denotes the WQFN package type, reel packaging, and specific manufacturing lot details.
Replacement Considerations
Direct replacements include other SN74AHCT86 variants with different packages such as SN74AHCT86DR or SN74AHCT86DBR. Cross-family alternatives like SN74HC86 may require voltage level adjustments due to non-TTL inputs.
