Texas Instruments SN74LVC1G98YEPR

Overview

SN74LVC1G98YEPR from Texas Instruments is a configurable multiple-function logic gate operating from 1.65 V to 5.5 V, supporting 5-V tolerant inputs, delivering ±24-mA output drive at 3.3 V, with max propagation delay of 6.3 ns and Schmitt-trigger input hysteresis. It enables flexible logic implementation in space-constrained I/O expansion, level-shifting, and signal conditioning circuits.

For engineers reviewing the SN74LVC1G98YEPR datasheet, SN74LVC1G98YEPR pinout, SN74LVC1G98YEPR application, or SN74LVC1G98YEPR equivalent, key selection criteria include its 6-pin YEP (DSBGA) package, configurable function table (MUX/AND/OR/NAND/NOR/inverter/buffer), Ioff support for live insertion, and operation across –40°C to 125°C industrial temperature range.

Technical Context

The SN74LVC1G98YEPR implements a 3-input configurable logic cell where In0–In2 select one of eight output functions via truth table mapping. Its Schmitt-trigger inputs provide hysteresis (ΔVT up to 1.11 V at 5.5 V), enabling noise immunity on slow or noisy signals.

It features Ioff circuitry that disables outputs during partial power-down, preventing back-drive current when VCC = 0 V. All inputs tolerate voltages up to 5.5 V regardless of VCC, supporting mixed-voltage system interfacing and down-translation.

FAQ

What logic functions can the SN74LVC1G98YEPR implement?

The SN74LVC1G98YEPR implements eight logic functions selected by its three inputs (In0–In2): 2-to-1 data selector with inverted output, 2-input NAND, 2-input NOR with one inverted input, 2-input AND with one inverted input, 2-input NAND with one inverted input, 2-input OR with one inverted input, 2-input NOR, noninverted buffer, and inverter. Each configuration is defined in the device's function table and supported by corresponding logic diagrams in the datasheet.

Does the SN74LVC1G98YEPR support hot-swap or partial power-down operation?

Yes, the SN74LVC1G98YEPR includes Ioff circuitry that disables outputs when VCC = 0 V, preventing damaging current backflow through the device during live insertion or partial power-down. This feature is explicitly characterized in the datasheet with Ioff ≤ ±10 µA across –40°C to 125°C, making SN74LVC1G98YEPR suitable for modular systems requiring safe board replacement without full system shutdown.

What is the significance of Schmitt-trigger inputs in the SN74LVC1G98YEPR?

The SN74LVC1G98YEPR uses Schmitt-trigger inputs with separate positive-going (VT+) and negative-going (VT–) thresholds - e.g., 2.61 V and 1.87 V at 5.5 V - providing up to 1.11 V hysteresis. This design rejects noise and eliminates contact bounce or slow-edge issues in mechanical switch interfaces, sensor outputs, or long-trace signals without requiring external RC networks or comparators.

Can the SN74LVC1G98YEPR interface between 5-V and 3.3-V logic domains?

Yes, the SN74LVC1G98YEPR accepts input voltages up to 5.5 V regardless of VCC level, enabling direct connection to 5-V peripherals while powered from 3.3 V, 2.5 V, or even 1.8 V. Its output swing is rail-to-rail relative to VCC, so a 3.3-V-powered SN74LVC1G98YEPR drives valid LVC logic levels to downstream 3.3-V devices - achieving true bidirectional level translation without external components.

Which package type does SN74LVC1G98YEPR use, and what are its key mechanical attributes?

The SN74LVC1G98YEPR uses the YZP (DSBGA) package: a 6-ball NanoFree™ die-size ball grid array measuring 1.4 mm × 1.4 mm × 0.5 mm. It features 0.4-mm pitch, bottom-side solder balls aligned to JEDEC MO-287, and a thermal resistance (θJA) of 123°C/W. This package delivers the smallest PCB footprint among pin-compatible configurable logic ICs and supports fine-pitch reflow assembly with standard stencil designs.
