Overview
The SN74ALS86NSR is a catalog logic device containing four independent 2-input exclusive-OR gates. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating free-air temperature range from 0°C to 70°C. The component utilizes a 14-pin Small Outline Package (SOP/NS) with surface mount installation. Electrical characteristics include a low-level output current capability of 8 mA and a high-level output current of -0.4 mA at VCC = 5V. Propagation delay times vary between 2 ns and 17 ns depending on input conditions.
Feature Summary
- Contains four independent 2-input exclusive-OR gates performing Boolean functions Y = A ⊕ B
- Functions as a true/complement element by reproducing signals in true or inverted form based on control input states
- Supports equivalent logic symbols for identity, even-parity, and odd-parity applications
Applications
- True/complement signal reproduction circuits
- Logic-identity elements
- Even-parity checking systems
- Odd-parity generation circuits
Procurement Notes
Verify the specific ordering suffix 'SR' corresponds to the SOP package and tape-and-reel packaging configuration. Confirm RoHS compliance status and lead finish details via the manufacturer's official documentation before procurement. Ensure the selected variant matches the required commercial temperature range specifications.
Selection Notes
Select this component when four independent XOR gates are required in a single surface-mount package. Verify that the ALS series propagation delays meet system timing requirements. Ensure the design accommodates the specified low-level and high-level output current capabilities for the intended load conditions.
Part Context
This part belongs to the Texas Instruments SN74ALS86 family of logic devices. It is categorized under standard catalog products designed for general-purpose digital logic applications. The device is distinct from military-grade variants characterized for wider temperature ranges.
Replacement Considerations
SN74ALS86DR serves as a direct replacement offering identical functionality in the same SOIC package but with different reel quantities.
FAQ
What is the maximum operating temperature for the SN74ALS86NSR?
The SN74ALS86NSR is characterized for operation over an operating free-air temperature range of 0°C to 70°C.
How does the device function as a true/complement element?
If one input is low, the other input is reproduced in true form at the output. If one input is high, the signal on the other input is reproduced inverted at the output.
