Product details
Overview
SN74LVC1G97DSFR 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 supply range, ±24 mA output 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 SN74LVC1G97DSFR datasheet, SN74LVC1G97DSFR pinout, SN74LVC1G97DSFR application, or SN74LVC1G97DSFR equivalent, key selection criteria include configurable logic function mapping, hysteresis thresholds (VT+ = 2.16–2.74 V / VT– = 1.41–1.9 V at 4.5 V), 6.3 ns max tpd at 3.3 V, Ioff-enabled partial-power-down operation, and NanoFree™ 1.00 mm × 1.00 mm SON-6 package compatibility.
Technical Context
The SN74LVC1G97DSFR 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 = 0.71–1.04 V at 4.5 V), improving noise immunity in noisy environments.
Designed for 1.65–5.5 V VCC operation, it supports voltage-level translation: inputs tolerate up to 5.5 V regardless of VCC, and outputs down-translate to VCC. The Ioff feature disables outputs during power-down, preventing back-drive current and enabling hot-plug capability in partial-power-down systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables interoperability across mixed-voltage logic domains (e.g., 1.8 V MCU interfacing with 5 V sensors) |
| Max Propagation Delay | 6.3 ns at 3.3 V - supports high-speed signal conditioning in timing-critical paths like sensor interface enable control |
| Input Hysteresis (ΔVT) | 0.71 V at 4.5 V - provides robust noise rejection for slow-rising or noisy digital signals in industrial field transmitters |
| Output Drive | ±24 mA at 3.3 V - sufficient to directly drive LEDs, small relays, or fanout to multiple 74LVC inputs without buffering |
| Ioff Current | ±10 µA at 5.5 V - ensures safe live insertion and prevents back-current damage when VCC = 0 V in modular systems |

Pinout & Package
SN74LVC1G97DSFR uses the SON-6 (DSF) package: 1.00 mm × 1.00 mm body, 0.5-mm pitch, wettable flank terminals, and bottom-side thermal pad for enhanced thermal performance in space-constrained PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| In0 (Pin 3) | Configurable logic input A | One of three address/control bits determining logic function; accepts 0–5.5 V independent of VCC |
| In1 (Pin 1) | Configurable logic input B | Second input bit for function selection; Schmitt-triggered for noise immunity on slow edges |
| In2 (Pin 6) | Configurable logic input C | Third input bit; combined with In0/In1 to select one of nine logic modes per truth table |
| GND (Pin 2) | Ground reference | Return path for all internal logic and output currents; must be low-impedance for stable hysteresis thresholds |
| VCC (Pin 5) | Supply voltage | Power rail defining logic levels and output swing; bypassing with 0.1 µF capacitor required per TI layout guidelines |
| Y (Pin 4) | Configurable logic output | Active-drive output supporting ±24 mA; disabled during Ioff mode to prevent backflow into powered-down subsystems |
Key Features
| Feature | Design Value |
|---|---|
| Configurable logic function | Selects among nine discrete Boolean operations (e.g., 2:1 MUX, AND, OR, NAND) using only three input pins-reduces BOM count and board area vs. fixed-function gates |
| Schmitt-trigger inputs | Provides 0.71 V hysteresis at 4.5 V supply-enables reliable switching on slow or noisy signals from mechanical switches, analog comparators, or long traces |
| Ioff partial-power-down | Disables outputs and limits leakage to ±10 µA when VCC = 0 V-supports hot-swap capability in modular instrumentation and server PSUs |
| 5.5-V tolerant I/O | Inputs accept up to 5.5 V regardless of VCC setting-allows direct interfacing with legacy 5 V peripherals while operating from 1.8 V or 3.3 V rails |
| NanoFree™ packaging | SON-6 (1.00 mm × 1.00 mm) die-as-package construction-delivers smallest footprint in its class for ultra-compact portable and wearable electronics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar configurable logic gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G98DSFR | Same SON-6 package and 1.65–5.5 V range, but offers 4-input configurable logic (16 function modes) and higher ICC (20 µA max). | Better suited for designs requiring more complex combinational logic or additional input flexibility; not drop-in compatible due to different pinout and truth table. | Choose SN74LVC1G98DSFR when 3-input limitation restricts required functionality; verify PCB layout changes for Pin 1 (In1) and Pin 6 (In2) reassignment. |
| 74LVC1G57GW,125 | NXP part in SC-70-6 package (2.0 × 1.25 mm); identical 3-input configurable function set but lower max output drive (±24 mA at 3.3 V same), no Ioff, and no 5.5-V tolerance. | Lacks Ioff and overvoltage tolerance-unsuitable for hot-swap or mixed-voltage systems; requires external clamping for 5 V inputs. | Select 74LVC1G57GW,125 only in cost-sensitive, single-supply 3.3 V designs where partial-power-down and 5 V interfacing are unnecessary. |
Compared with SN74LVC1G97DSFR, SN74LVC1G98DSFR adds input flexibility at the cost of layout change, while 74LVC1G57GW,125 sacrifices Ioff and overvoltage robustness for lower unit cost-making SN74LVC1G97DSFR optimal for compact, mixed-voltage, hot-pluggable applications.

FAQ
What logic functions does the SN74LVC1G97DSFR support?
The SN74LVC1G97DSFR supports nine configurable logic functions: 2-to-1 multiplexer, 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 combination of the three inputs (In0, In1, In2) per the device's truth table. All configurations operate within the 1.65–5.5 V supply range and retain Schmitt-trigger input behavior.
Does the SN74LVC1G97DSFR support hot-swap or live-insertion applications?
Yes, the SN74LVC1G97DSFR supports live insertion via its Ioff feature. When VCC = 0 V, the Ioff circuitry disables the output and limits off-state current to ±10 µA, preventing damaging back-current flow from powered system nodes into the unpowered device. This makes SN74LVC1G97DSFR suitable for modular instrumentation, server backplanes, and field-replaceable units where cards may be inserted or removed under power.
What is the package type and size of the SN74LVC1G97DSFR?
The SN74LVC1G97DSFR uses the SON-6 (DSF) package: a 1.00 mm × 1.00 mm body with 0.5-mm pitch and wettable flank terminals. It features a bottom thermal pad for improved heat dissipation and is compatible with standard SMT reflow profiles (MSL Level-1, peak reflow 260°C). This NanoFree™ package is the smallest in the SN74LVC1G97 family, optimized for ultra-dense portable and wearable electronics.
Can the SN74LVC1G97DSFR interface with 5 V logic while operating from a 1.8 V supply?
Yes, the SN74LVC1G97DSFR accepts input voltages up to 5.5 V regardless of VCC level, enabling true 5 V-tolerant operation at 1.8 V supply. Its outputs swing from GND to VCC (1.8 V), so level translation occurs inherently-no external components are needed to interface with 5 V sensors, microcontrollers, or legacy peripherals. This capability is confirmed in the "Recommended Operating Conditions" and "Electrical Characteristics" sections of the official datasheet.
How does the Schmitt-trigger input improve noise immunity in the SN74LVC1G97DSFR?
The SN74LVC1G97DSFR incorporates Schmitt-trigger inputs with hysteresis (ΔVT = 0.71–1.04 V at 4.5 V), meaning the positive-going threshold (VT+) and negative-going threshold (VT–) differ significantly. This prevents multiple output transitions when input signals have slow edges or superimposed noise-critical in applications like mechanical switch debouncing, analog comparator outputs, or long PCB traces in industrial environments. The hysteresis value is guaranteed across temperature and supply voltage.
