Description

SN74LVC02AD is TI’s dual 2-input NOR gate in the SN74LVC family. It contains two independent NOR gates with outputs equal to the NOR of their inputs (Y = ¬(A OR B) for each gate). It operates from a single supply Vcc in the 1.65 V to 3.6 V range (common 3.3 V systems) with low static CMOS power and standard CMOS input thresholds around Vcc/2. Inputs must not be driven above Vcc. Outputs are push-pull and can drive moderate loads (drive specs in the datasheet). The “AD” suffix denotes a specific package option (typically 8-pin small-outline) and related packaging/temperature variants. Applications include simple digital logic gating, decoding, and clock-control in low-voltage designs. For exact operating conditions, pinout, and electrical characteristics, refer to the TI datasheet.

Features

Here are the key features of SN74LVC02AD:
- Dual 2-input NOR gates (two independent gates)
- Wide supply range: Vcc = 1.65 V to 3.6 V (low-voltage CMOS)
- Ioff supports partial-power-down (no back-powering when Vcc is 0)
- Push-pull (totem-pole) outputs
- Very low static/dynamic power consumption
- 8-pin package (compact)
- Industrial temperature range: typically -40°C to 125°C
Ideal for low-power, high-speed NOR logic in portable and mixed-signal circuits.

Package

8-pin small-outline IC package (SOIC).

Pinout

- Pin count: 14 pins
- Function: Dual 2-input NOR gate (two independent NOR gates; outputs Y1 = ¬(A1 ∨ B1), Y2 = ¬(A2 ∨ B2))

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI).
- What kind of company: TI is an American multinational semiconductor company that designs and manufactures analog and digital integrated circuits and related products, headquartered in Dallas, Texas.

Application

SN74LVC02AD is a dual 2-input NOR gate in the LVC family. Applications:
- General-purpose digital logic: NOR-based functions and simple combinational circuits
- Clock gating and enable/control logic
- Address/data decoding and control signal generation
- Level shifting/interface between voltage domains (1.65–3.3 V)
- Driving/gating signals for microcontrollers, FPGAs, DSPs in low-power portable electronics

Equivalent

SN74LVC02AD is TI’s quad 2‑input NOR gate in the LVC family (1.65–5.5 V). A direct cross/equivalent from other vendors is Nexperia 74LVC02D (quad 2‑input NOR, LVC). Other manufacturers offer similar LVC NOR devices; when substituting, verify pinout and package in the cross-reference table.
