Product details

Quad 2-Input NAND with open-collector outputs

The SN74LS26D is a Texas Instruments 74LS-series quad 2-input NAND gate featuring open-collector outputs. Each of the four independent gates drives a wired-AND bus or interfaces to higher-voltage logic without external level shifting. Open-collector outputs sink up to 8 mA per channel (low state) and float high, allowing multiple gates to share a common pull-up resistor for wired-AND configurations.

Supply and timing envelope

Propagation delay is 32 ns max at 5 V with a 15 pF load, suitable for bus-oriented logic running at moderate clock rates.

Supplied in a 14-SOIC package (0.154" body width, 3.90 mm) with a tube carrier. The surface-mount footprint is standard for SOIC-14 and mates with common pick-and-place and reflow profiles.

Frequently asked questions

Is SN74LS26D functionally equivalent to MM74HC86MTC?

No. The MM74HC86MTC is a quad 2-input XOR gate from the 74HC family, while the SN74LS26D is a quad 2-input NAND gate with open-collector outputs. They are not pin-compatible or functionally interchangeable — the logic function and output structure differ.

What compliance documentation does Texas Instruments provide for SN74LS26D?

Texas Instruments provides ROHS3 compliance for the SN74LS26D. No UL, IEC, or REACH documentation is listed in the available records.
