Overview
The SN74AS86ADG4 is a commercial-grade, quad 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 of 0°C to 70°C. The device utilizes the AS logic family and features a SOIC-14 package. Electrical characteristics include a maximum propagation delay of 7.5 ns at 5.5 V with a 50 pF load, a low-level output current capability of 20 mA, and a high-level output current capability of -2 mA.
Feature Summary
- Contains four independent 2-input exclusive-OR gates performing Boolean functions Y = A ⊕ B
- Capable of functioning as a true/complement element for signal inversion or reproduction
- Supports equivalent logic symbols for parity generation and identity operations
Applications
- True/complement signal elements
- Even-parity generation circuits
- Odd-parity generation circuits
Procurement Notes
Verify that the ordering suffix 'G4' corresponds to lead-free and RoHS-compliant specifications as defined in the manufacturer's documentation. Confirm the specific package variant matches the required board layout dimensions. Ensure the component status aligns with long-term availability requirements for the intended production cycle.
Selection Notes
Select this component when high-speed switching performance is required compared to standard ALS logic families. The AS series provides faster propagation delays suitable for high-frequency digital applications. Verify that the 20 mA low-level output current meets the fan-out requirements of the connected loads.
Part Context
This part belongs to the Texas Instruments SN74AS86A series of exclusive-OR gates. It is the commercial temperature version (SN74) of the military-grade SN54AS86A. The 'D' designation indicates the Small Outline Integrated Circuit (SOIC) package format.

- SN74AS86AN
FAQ
What is the maximum propagation delay for the SN74AS86ADG4?
The maximum propagation delay is 7.5 ns when operating at 5.5 V with a 50 pF capacitive load.
How does the device function as a true/complement element?
If one input is held low, the other input is reproduced in true form at the output. If one input is held high, the other input is reproduced in inverted form at the output.
