SN74ACT86PW

Overview

The SN74ACT86PW is a quadruple 2-input exclusive-OR gate manufactured by Texas Instruments. It belongs to the 74ACT logic series and operates within a supply voltage range of 4.5 V to 5.5 V. The device features four independent XOR circuits, providing eight inputs and four outputs. It utilizes a 14-TSSOP surface-mount package with a width of 4.40 mm. Electrical characteristics include a maximum propagation delay of 9.5 ns at 5 V with a 50 pF load, and output drive currents of 24 mA for both high and low states. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides four independent 2-input exclusive-OR logic functions in a single integrated circuit
• Delivers high-speed signal processing with a maximum propagation delay of 9.5 ns under standard test conditions
• Offers robust output drive capability with symmetric sourcing and sinking currents of 24 mA
• Compatible with standard CMOS logic families while accepting TTL-level input signals

Applications

• Digital data path selection and multiplexing circuits
• Parity generation and error detection modules
• Binary arithmetic logic units for addition and subtraction operations
• Control logic implementation in embedded systems

Procurement Notes

Verify the specific suffix 'PW' confirms the 14-TSSOP plastic small-outline package variant during procurement. Confirm RoHS compliance status as per current manufacturer documentation. Ensure the design accommodates the 4.5 V to 5.5 V supply voltage constraint. Validate that the 9.5 ns propagation delay meets system timing requirements under expected capacitive loads.

Selection Notes

Select this component when four independent XOR gates are required in a compact surface-mount form factor. Choose the ACT series for faster switching speeds compared to standard HC or HCT counterparts. Ensure the application environment remains within the specified -40°C to +85°C temperature range. Verify that the 5 V supply voltage aligns with the target system power architecture.

Part Context

This part is a member of the Texas Instruments 74ACT family, which bridges the performance gap between older TTL and modern CMOS technologies. The SN74AC86PWG4 represents a lead-free variant within the broader AC series, offering similar functionality but with extended voltage flexibility down to 2 V. The SN74ACT86PWR denotes the same functional device packaged in tape-and-reel format for automated assembly processes.
