Product details
Overview
SN74LVC3G57 from Texas Instruments is a triple configurable multiple-function gate IC with Schmitt-trigger inputs, operating from 1.1V to 3.6V supply, supporting AND/OR/NAND/NOR/XNOR/inverter/buffer logic per channel, and featuring 5.5V-tolerant inputs for mixed-voltage interfacing in power sequencing and signal enable applications.
For engineers reviewing the SN74LVC3G57 datasheet, SN74LVC3G57 pinout, SN74LVC3G57 application, or SN74LVC3G57 equivalent, this device delivers configurable logic in compact WQFN-14 or TSSOP-14 packages with hysteresis-enabled noise immunity, low ICC (≤40 µA), and propagation delays as low as 5.6 ns at 3.3V - critical for robust digital interface design in space-constrained industrial and portable systems.
Technical Context
The SN74LVC3G57 implements three independent 3-input configurable logic gates, each mapping A/B/C inputs to Y output via user-selectable truth tables. Each channel uses CMOS Schmitt-trigger inputs with programmable hysteresis (ΔVT = 0.07–1.2 V), enabling reliable operation with slow-rising or noisy signals without external conditioning.
Its balanced push-pull outputs drive ±24 mA at 3.0V while maintaining VOH ≥ 2.2 V and VOL ≤ 0.55 V, and its 5.5V input tolerance allows direct interfacing with legacy 5V logic without level shifters. The device supports simultaneous multi-channel configuration with no inter-channel dependency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 1.1 V to 3.6 V - enables single-supply operation across 1.2V, 1.8V, 2.5V, and 3.3V logic domains |
| Input voltage tolerance | 5.5 V - permits direct connection to 5V signals without external clamping or translation |
| Propagation delay (tpd) | 5.6 ns at 3.3V/50pF - ensures timing-critical signal routing in high-speed control paths |
| Hysteresis (ΔVT) | 0.07–1.2 V (VCC-dependent) - rejects noise up to 1.2 Vpp on slow edges, eliminating need for RC filters |
| Output drive strength | ±24 mA at 3.0V - sufficient to directly drive multiple 74LVC inputs or small LEDs without buffers |
| Quiescent current (ICC) | 40 µA max at 3.6V - supports ultra-low-power battery-operated systems with minimal standby drain |
| ESD rating (HBM) | ±2000 V - meets IEC 61000-4-2 Level 2 for board-level robustness in industrial environments |
Pinout & Package
SN74LVC3G57 is available in two surface-mount packages: PW (14-pin TSSOP, 5.0 mm × 6.4 mm body) and BQA (14-pin WQFN, 3.0 mm × 2.5 mm body with thermal pad). Both are RoHS-compliant and lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, A2, A3 | Input A for channels 1–3 | Three independent logic inputs accepting Schmitt-trigger thresholds; must be terminated to VCC or GND if unused |
| B1, B2, B3 | Input B for channels 1–3 | Second set of three independent logic inputs; compatible with slow/noisy signals due to hysteresis |
| C1, C2, C3 | Input C for channels 1–3 | Third set of three independent logic inputs; defines full 3-bit function selection per channel |
| Y1, Y2, Y3 | Output Y for channels 1–3 | CMOS push-pull outputs capable of sourcing/sinking up to ±24 mA; may be paralleled for higher drive |
| VCC | Positive supply | Single supply pin for all three channels; requires local 0.1 µF bypass capacitor per layout guidelines |
| GND | Ground reference | Common return path for all channels and supply; thermal pad (BQA only) may connect to GND for improved thermal performance |
Key Features
| Feature | Design Value |
|---|---|
| Triple independent configurable gates | Each channel implements one of seven logic functions (AND, OR, NAND, NOR, XNOR, inverter, buffer) via 3-bit input mapping |
| Schmitt-trigger inputs with programmable hysteresis | ΔVT up to 1.2 V at 3.6V enables reliable switching on slow edges (e.g., power-good ramps) without external components |
| 5.5V-tolerant inputs | Allows direct interface with 5V microcontrollers, sensors, or legacy peripherals without level-shifting circuitry |
| Low quiescent current | ICC ≤ 40 µA at 3.6V supports always-on monitoring circuits in energy-sensitive applications |
| Compact dual-package options | WQFN-14 (3.0 × 2.5 mm) reduces PCB area by >50% vs. TSSOP-14 (5.0 × 6.4 mm) for space-constrained designs |
Applications
| Power Sequencing Control | Signal Enable / Gate Logic |
|---|---|
|
Use Scenario: Coordinating startup order of multiple voltage rails (e.g., core, I/O, analog) in FPGA or MCU-based systems to prevent latch-up or brownout.

Equivalent & Alternatives
The following parts are listed as comparable options for similar configurable logic gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G97DBVR | Single-channel version in SOT-23-6; identical 1.1–3.6V range and 5.5V-tolerant inputs but lacks triple-gate integration | Requires three units to match SN74LVC3G57 functionality; increases PCB area and assembly cost | Select when only one configurable gate is needed and board space permits discrete placement |
| 74LVC1G57GW,125 | NXP variant in SC-70-6 package; same logic configurability and Schmitt inputs but rated only to 3.3V supply (no 3.6V support) | Not suitable for 3.6V systems or applications requiring extended voltage margin for aging or ripple | Choose only for 3.3V-only designs where NXP supply chain preference applies |
Compared with SN74LVC3G57, SN74LVC1G97DBVR offers identical per-channel performance but triples footprint and component count, while 74LVC1G57GW,125 sacrifices 0.3V supply headroom and lacks TI's documented thermal derating curves for 125°C operation - making SN74LVC3G57 the optimal choice for compact, wide-voltage, multi-channel logic integration.

FAQ
What logic functions does the SN74LVC3G57 support per channel?
The SN74LVC3G57 supports seven configurable logic functions per channel - AND, OR, NAND, NOR, XNOR, inverter, and buffer - determined by the eight possible combinations of its three inputs (A, B, C). This is explicitly defined in Table 7-1 (Function Table) and illustrated in Figure 7-2 (Configuration Examples) of the official SN74LVC3G57 datasheet. No external programming or configuration pins are required; function selection is purely combinatorial.
Can the SN74LVC3G57 operate with a 5V supply?
No, the SN74LVC3G57 cannot operate with a 5V supply. Its absolute maximum VCC rating is 6.5V, but its recommended operating range is strictly 1.1V to 3.6V per Section 5.3 of the datasheet. While its inputs tolerate up to 5.5V, applying 5V to VCC violates the Recommended Operating Conditions and risks incorrect logic levels, excessive ICC, and accelerated device degradation. Always use VCC within 1.1–3.6V for guaranteed functionality.
How does the Schmitt-trigger input benefit noise immunity in the SN74LVC3G57?
The Schmitt-trigger inputs in the SN74LVC3G57 provide hysteresis (ΔVT) ranging from 0.07 V to 1.2 V depending on VCC, meaning the positive-going threshold (VT+) and negative-going threshold (VT−) differ significantly. This prevents oscillation on slow or noisy input edges - for example, a 3.3V supply yields ΔVT ≈ 0.3–1.2 V - allowing reliable detection of power-good ramps or switch closures without external filtering. This behavior is verified in Section 5.5 Electrical Characteristics and Section 7.3.1 Feature Description.
Is the SN74LVC3G57 pin-compatible with other 3-input configurable gates like the SN74LVC1G97?
No, the SN74LVC3G57 is not pin-compatible with SN74LVC1G97. The SN74LVC3G57 is a triple-gate device in 14-pin TSSOP (PW) or WQFN (BQA) packages, with dedicated pins for A1–A3, B1–B3, C1–C3, Y1–Y3, VCC, and GND. In contrast, SN74LVC1G97 is a single-gate device in 6-pin SOT-23 or SC-70 packages. Their pin counts, layouts, and signal assignments are fundamentally incompatible; substituting one for the other requires PCB redesign.
What is the maximum capacitive load the SN74LVC3G57 can drive while meeting datasheet timing specs?
The SN74LVC3G57 is characterized to meet all switching specifications (e.g., tpd ≤ 5.6 ns) with a 50 pF load capacitance at 3.3V, as specified in Section 5.6 Switching Characteristics and reinforced in Section 8.2.1.2. Driving loads >50 pF increases propagation delay and may cause ringing or overshoot; if larger loads are unavoidable, TI recommends adding a series resistor between output and load to limit peak current per Absolute Maximum Ratings (IO ≤ ±50 mA). Layout best practices emphasize short traces and local decoupling to maintain signal integrity.
