SN74LVC1G18YEAR

Overview

The SN74LVC1G18YEAR is a single 1-of-2 noninverting demultiplexer with 3-state deselected outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 5.5 V and accepts input voltages up to 5.5 V. The device features low power consumption with a maximum ICC of 10 μA and supports partial-power-down mode via Ioff circuitry. It provides ±24 mA output drive at 3.3 V and includes ESD protection exceeding 2000 V (HBM). Packaged in the NanoStar YEA format, it functions over an operating temperature range of -40°C to 85°C.

Feature Summary

• Supports 5-V VCC operation with inputs accepting voltages up to 5.5 V
• Features Ioff circuitry that disables outputs to prevent damaging current backflow during partial-power-down
• Provides 3-state deselected outputs for efficient bus management

Applications

• Partial-power-down applications requiring controlled output disabling
• Bus-oriented switching and data routing
• Portable and battery-powered equipment

Procurement Notes

Verify component status as NRND (Not Recommended for New Designs) before procurement. Confirm package type matches design requirements. Check RoHS compliance and lead finish specifications against project constraints. Ensure availability aligns with production timelines given discontinued status.

Selection Notes

Select this component for designs requiring a compact 1-of-2 demultiplexer with 3-state outputs. Consider the NanoStar YEA package for space-constrained layouts. Verify compatibility with system voltage levels between 1.65 V and 5.5 V. Evaluate thermal performance and ESD protection needs against application environment.

Part Context

Part of the SN74LVC1G18 family of 1-of-2 noninverting demultiplexers. Manufactured using Texas Instruments' NanoStar technology, which utilizes the die as the package. Designed for low-voltage CMOS logic applications requiring high speed and low power consumption.

Replacement Considerations

SN74LVC1G18YZAR and SN74LVC1G18YZPR are alternative packages within the same family. Verify pinout and electrical characteristics match before substitution.
