Detailed Description

Dual non-inverting buffer/line driver with 3‑state (high‑impedance) outputs and independent enables. Belongs to the 74LVC low‑voltage CMOS logic family. Operates from a low supply while tolerating higher input levels. Ideal for bus isolation, signal gating, and general-purpose buffering. Housed in a compact VSSOP-8 package. Current available stock: 6100 units.

Key Features

Function: 2 independent non-inverting buffers with active‑HIGH output enable (OE)

Three-state outputs: allows bus sharing and isolation

Wide supply range for LVC: supports low-voltage operation (typical LVC family)

5 V tolerant inputs/outputs when powered at lower VCC (typical for LVC family; check datasheet for exact limits)

Fast switching and low propagation delay for high-speed digital lines

Low static power: CMOS inputs with very low ICC when inputs are not floating

Robust ESD protection on I/O pins (see datasheet levels)

Pin-to-pin compatible with industry-standard 74LVC2G126 across vendors

Key Advantages

Simple way to gate or isolate two signals independently using one small IC

High-speed operation with clean edges for reliable digital timing

5 V tolerant I/Os (when powered lower) ease mixed-voltage interfacing

Tiny 8‑pin VSSOP saves PCB area and simplifies routing

Low power consumption reduces heat and extends battery life in portable designs

Broad ecosystem and multi-vendor second sourcing reduces supply risk

Packaging

Type: VSSOP-8 (very thin shrink small-outline), 8 leads, gull-wing

Case code: 1021 (as provided)

Material: Molded epoxy plastic body, tin-plated copper alloy leads (RoHS-compliant; verify finish in datasheet)

Approximate size: compact 8‑pin small-outline footprint suitable for dense layouts (typical VSSOP body ~3 x 3 mm with fine lead pitch; check datasheet for exact dimensions and land pattern)

Pin configuration (typical for 74LVC2G126): two data inputs (A1, A2), two outputs (Y1, Y2), two enables (OE1, OE2), VCC, GND

Thermal characteristics: small-body package with moderate thermal resistance; ensure adequate copper for heat spreading and follow datasheet derating

Electrical properties (family typicals; confirm in datasheet):

- Supply: low-voltage CMOS operation (LVC family)

- I/O tolerance: inputs/outputs tolerant to higher logic levels when VCC is lower

- Output drive: strong CMOS drive suitable for most logic loads

- Propagation delay: fast, suitable for high-speed digital lines

Lifecycle

Status: Active in mass production by NXP’s standard logic lineage (often also supplied under Nexperia branding for logic devices)

Not nearing discontinuation based on industry status of 74LVC family

Equivalent or alternative models (verify pinout, drive strength, and electrical limits against your design):

- Texas Instruments SN74LVC2G126 (available in VSSOP/TSSOP and other small packages)

- Nexperia 74LVC2G126 (e.g., package variants GW/DC; same function and family)

- ON Semiconductor / onsemi NC7WZ126 (dual non-inverting buffer with 3‑state outputs; different logic family, check specs)

- Diodes Incorporated 74LVC2G126 (family-compatible alternative)

- Fairchild/ON NC7SZ126 or SN74LVC1G126 (single‑gate versions if only one channel is needed)
