Detailed Description

Dual-supply, 2-bit level-translating bus transceiver for mixed-voltage systems. Side A and Side B each use their own supply rails to shift signals cleanly between low-voltage logic and higher-voltage logic. Direction is set by a DIR pin and outputs can be 3-stated with OE for easy bus sharing and isolation. LVC family performance delivers fast edges, low power, and robust 5 V tolerant inputs with Ioff for partial power-down. Ideal for microcontroller, FPGA, and ASIC interfaces where simple, reliable level translation is needed. Stock available now, typical Pb‑free build as indicated by 14+PBF

Key Features

Dual-supply operation for real level translation between two rails

Two channels to translate two independent signals

Direction control pin for A-to-B or B-to-A selection

Output enable pin to place outputs in high impedance

5 V tolerant inputs and Ioff support for safe power sequencing

Fast CMOS switching with low propagation delay and low quiescent current

Wide logic rail coverage across common system voltages

Robust ESD protection and LVC family reliability

RoHS compliant and Pb‑free build

Key Advantages

Simple wiring and control for quick design-in

Replaces discrete solutions to save board space and cost

Stable operation across mixed-voltage rails in modern designs

Safe behavior during partial power-down and hot-plug events

Balanced drive strength for clean edges and reduced signal integrity issues

Broad ecosystem and cross-availability for long-term sourcing

Packaging

Type: Surface-mount IC, GT variant commonly supplied in compact 10-pin outlines such as TSSOP-10 or XQFN-10; listing indicates case code 7726

Material: Molded epoxy package with matte tin lead finish, Pb‑free and RoHS compliant

Size: Small footprint suitable for dense boards; typical TSSOP-10 body around 3 mm x 3–4.4 mm, XQFN-10 around 2 mm x 2 mm; confirm exact GT outline in the datasheet

Pin configuration: Two A-side I/Os, two B-side I/Os, DIR, OE, VCCA, VCCB, and ground pins arranged for straightforward routing

Thermal characteristics: Designed for wide ambient operation (commonly −40 to +125°C); thermal resistance depends on package and PCB copper area; ensure adequate pad and copper for heat spreading

Electrical properties: CMOS outputs, 5 V tolerant inputs, Ioff for partial power-down, low ICC, fast transitions suitable for high-speed GPIO and serial signals; see datasheet for exact voltage ranges and timing

Shipment form: Tape and reel standard for automated assembly; cut tape and tray options may be available on request
