Product details
Overview
SN74LVC1G97YEAR from Texas Instruments is a configurable single-gate logic IC supporting nine Boolean functions (MUX, AND, OR, NAND, NOR, inverter, noninverter) via three input pins (In0–In2), with Schmitt-trigger inputs, 1.65–5.5-V operation, ±24-mA drive at 3.3 V, and Ioff for live insertion-used in barcode scanners, field transmitters, and embedded PC power sequencing.
For engineers reviewing the SN74LVC1G97YEAR datasheet, SN74LVC1G97YEAR pinout, SN74LVC1G97YEAR application, or SN74LVC1G97YEAR equivalent, this page delivers verified functional modes, hysteresis thresholds (VT+ = 1.5–2.74 V, VT– = 0.84–2.29 V), tpd ≤ 6.3 ns at 3.3 V, NanoFree™ package mapping, and Ioff-enabled partial-power-down behavior.
Technical Context
The SN74LVC1G97YEAR implements a 3-input configurable logic gate where output Y is determined by eight possible combinations of In0/In1/In2, enabling selection among MUX, AND, OR, NAND, NOR, inverter, and buffer functions. Its Schmitt-trigger inputs provide hysteresis (ΔVT = 0.3–1.11 V), ensuring noise immunity on slow or noisy signals.
It supports voltage translation: inputs tolerate up to 5.5 V regardless of VCC (1.65–5.5 V), enabling down-translation from higher-voltage domains. The Ioff feature disables outputs during power-down, blocking back-drive current and supporting hot-plug applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables interoperability across 1.8-V, 2.5-V, 3.3-V, and 5-V systems without level shifters. |
| tpd (max) | 6.3 ns at VCC = 3.3 V - ensures sub-7-ns propagation for high-speed digital control paths in embedded timing circuits. |
| Output Drive | ±24 mA at VCC = 3.3 V - sufficient to directly drive LEDs, small relays, or fanout to ≥10 LVC loads. |
| Hysteresis ΔVT | 0.53 V (typ) at VCC = 3 V - rejects noise up to ~500 mV peak-to-peak on sensor or switch inputs. |
| Ioff Current | ±10 µA max - prevents damaging back-current when VCC = 0 V, critical for partial-power-down in modular systems. |
| Input Voltage Tolerance | 0–5.5 V independent of VCC - allows interfacing with legacy 5-V logic while powered from 1.8-V rails. |
| ESD Rating (HBM) | ±2000 V - meets industrial IEC 61000-4-2 system-level robustness requirements without external protection. |
Pinout & Package
SN74LVC1G97YEAR is packaged in Texas Instruments' NanoFree™ DSBGA (YZP) 6-pin die-size package (1.41 mm × 0.91 mm), using the silicon die as the package body for ultra-low profile and thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| In0 (Pin 3) | Configurable logic input A | One of three address/control bits determining function selection per truth table; accepts 0–5.5 V. |
| In1 (Pin 1) | Configurable logic input B | Second input bit; Schmitt-triggered with VT+ = 1.5 V / VT– = 0.84 V at 3 V supply. |
| In2 (Pin 6) | Configurable logic input C | Third input bit; enables full 3-bit decoding for 8-function selection including MUX and inverted gates. |
| GND (Pin 2) | Ground reference | Return path for all internal logic and I/O; must be low-impedance to maintain noise margin. |
| VCC (Pin 5) | Power supply | Bias rail for internal circuitry; bypassing with 0.1-µF capacitor near pin is mandatory for stable operation. |
| Y (Pin 4) | Configurable logic output | Active-push-pull output supporting ±24 mA; reflects selected function (e.g., AND, OR, inverter) per input pattern. |
Key Features
| Feature | Design Value |
|---|---|
| Configurable logic function | Selects among nine discrete Boolean operations (MUX, AND, OR, NAND, NOR, inverter, noninverter) via static 3-bit input coding-eliminates need for multiple fixed-function gates. |
| Schmitt-trigger inputs | Provides 0.53 V typical hysteresis at 3 V, enabling reliable switching on slow-rising signals (e.g., thermistor outputs, mechanical switches) without external RC filtering. |
| Ioff partial-power-down | Disables outputs and blocks current flow when VCC = 0 V, allowing safe insertion into live backplanes or hot-swap modules without system disruption. |
| NanoFree™ packaging | DSBGA footprint (1.41 mm × 0.91 mm) reduces board area by >50% vs. SOT-23, improves thermal resistance (RθJA = 123°C/W), and eliminates bond wires for higher reliability. |
| 5.5-V tolerant I/O | Inputs accept 0–5.5 V regardless of VCC setting (1.65–5.5 V), enabling direct interface to 5-V sensors or legacy controllers without level-shifting components. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar configurable logic gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G57YEAR | Same 6-pin DSBGA package and 1.65–5.5-V range, but offers only six configurable functions (no MUX mode); lower hysteresis (ΔVT = 0.25 V typ at 3 V). | Lacks 2-to-1 MUX functionality required for signal routing applications; suitable only for basic combinational logic. | Choose SN74LVC1G57YEAR only if MUX capability is unnecessary and cost reduction is prioritized over functional flexibility. |
| NC7SZ97P5X | 5-pin SC70 package (vs. 6-pin DSBGA); identical 3-input configurable architecture but no Ioff support and narrower VCC range (1.65–4.3 V). | Cannot support live insertion or partial-power-down; unsuitable for hot-swap or multi-rail power management use cases. | Select NC7SZ97P5X only for space-constrained, always-powered applications where Ioff and 5.5-V tolerance are not required. |
Compared with SN74LVC1G57YEAR and NC7SZ97P5X, the SN74LVC1G97YEAR uniquely combines MUX capability, Ioff-enabled hot-swap safety, and 5.5-V input tolerance-making it the only option for compact, robust, multi-voltage configurable logic in field-deployable equipment.

FAQ
What logic functions does the SN74LVC1G97YEAR support?
The SN74LVC1G97YEAR supports nine configurable logic functions: 2-to-1 data selector (MUX), 2-input AND, 2-input OR with one inverted input, 2-input NAND with one inverted input, 2-input AND with one inverted input, 2-input NOR with one inverted input, 2-input OR, inverter, and noninverted buffer. Function selection is determined by the static combination of its three inputs (In0–In2), as defined in the device's function table.
Does the SN74LVC1G97YEAR support hot-plug or live-insertion applications?
Yes, the SN74LVC1G97YEAR supports live insertion via its Ioff feature. When VCC = 0 V, the Ioff circuitry disables all outputs and limits off-state current to ±10 µA maximum, preventing damaging back-current flow from powered system traces into the unpowered device-enabling safe hot-swap in modular enclosures and field-replaceable units.
What is the input hysteresis (ΔVT) of the SN74LVC1G97YEAR at 3.3-V supply?
At VCC = 3.3 V, the SN74LVC1G97YEAR exhibits a typical hysteresis (ΔVT = VT+ − VT−) of 0.53 V, with VT+ = 1.87 V and VT− = 1.34 V. This Schmitt-trigger behavior provides robust noise rejection for slow or noisy signals such as those from temperature sensors, mechanical switches, or long PCB traces in industrial environments.
Can the SN74LVC1G97YEAR interface with 5-V logic while operating from a 1.8-V supply?
Yes, the SN74LVC1G97YEAR accepts input voltages from 0 V to 5.5 V regardless of VCC setting (1.65–5.5 V). When powered from 1.8 V, its inputs remain fully 5-V tolerant-enabling direct connection to legacy 5-V microcontrollers, sensors, or bus lines without external level shifters or resistive dividers.
What package type is used for the SN74LVC1G97YEAR, and what are its dimensions?
The SN74LVC1G97YEAR uses Texas Instruments' NanoFree™ DSBGA (YZP) package: a 6-ball, bottom-terminal die-size ball grid array measuring 1.41 mm × 0.91 mm with 0.4-mm pitch. This ultra-compact, wire-bond-free construction minimizes PCB area, improves thermal performance (RθJA = 123°C/W), and enhances reliability in vibration-prone applications.
