Product details
Overview
SN74LVC1G17DRLRG4 from Texas Instruments is a single Schmitt-trigger buffer IC designed for 1.65V to 5.5V operation, delivering 24mA output drive at 3.3V, 4.6ns max propagation delay, and 5.5V-tolerant inputs - used in noise-immune signal conditioning for consumer audio and portable display interfaces.
For engineers reviewing the SN74LVC1G17DRLRG4 datasheet, SN74LVC1G17DRLRG4 pinout, SN74LVC1G17DRLRG4 application, or SN74LVC1G17DRLRG4 equivalent, key selection criteria include Schmitt-trigger hysteresis (0.64V typ at 3V), Ioff support for live insertion, ±24mA drive capability, and ultra-compact DRL (SOT-5X3) 1.6mm × 1.6mm package compatibility with high-density PCB layouts.
Technical Context
The SN74LVC1G17DRLRG4 implements a noninverting Schmitt-trigger buffer (Y = A) with asymmetric input thresholds: VT+ = 1.48V and VT− = 0.89V at VCC = 3V, yielding 0.59V hysteresis to reject slow-rising or noisy signals. It operates across −40°C to 125°C with full Ioff functionality enabling partial power-down mode.
This device uses CMOS technology with rail-to-rail output swing, supports down-translation (e.g., 5V input → 3.3V output), and features ESD protection exceeding 2000V HBM, 1000V CDM, and 200V MM - validated per JESD22 and JESD78 Class II latch-up standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - enables interoperability across mixed-voltage systems including 1.8V, 2.5V, 3.3V, and 5V logic domains. |
| Input Voltage Tolerance | Up to 5.5V - allows direct interfacing with higher-voltage sources without level-shifting circuitry. |
| tpd (Max) | 4.6ns at VCC = 3.3V, CL = 15pF - supports clean signal buffering up to ~100MHz digital timing paths. |
| Output Drive | ±24mA at VCC = 3.3V - sufficient to drive multiple LVC loads or moderate capacitive traces without external buffers. |
| Hysteresis ΔVT | 0.59V typical at VCC = 3V - provides robust noise margin against EMI and contact bounce in mechanical switch debouncing. |
| Ioff Current | ±10μA max - prevents back-drive current during power sequencing, enabling safe hot-plug and partial-power-down operation. |
| ICC (Max) | 10μA - ensures ultra-low static power consumption ideal for battery-powered portable devices. |
Pinout & Package
SN74LVC1G17DRLRG4 is packaged in the DRL (SOT-5X3) 5-pin surface-mount package, measuring 1.6mm × 1.6mm body size with 0.5mm pitch. This ultra-small footprint saves board space while maintaining manufacturability in high-volume SMT assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (A) | Noninverting Schmitt-trigger input; accepts 0–5.5V; triggers at VT+ (1.48V) on rising edge and VT− (0.89V) on falling edge at 3V supply. |
| 2 | GND | Ground reference for all internal circuitry and output stage; must be low-impedance for stable hysteresis and drive performance. |
| 3 | Output (Y) | CMOS rail-to-rail buffered output; delivers ±24mA at 3.3V; compatible with LVC/LVT logic families and 50Ω transmission lines. |
| 4 | VCC | Power supply input; decoupling capacitor (0.1μF) required adjacent to pin to suppress switching noise and ensure timing stability. |
| 5 | No Connect (N.C.) | Internally unconnected terminal; must remain floating - no external connection or biasing permitted. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | Provides 0.59V typical hysteresis at 3V, enabling reliable signal recovery from slow edges or noisy environments like mechanical switch inputs. |
| 5.5V-tolerant inputs | Allows direct connection to 5V buses while operating from lower VCC (e.g., 1.8V/2.5V/3.3V), eliminating need for discrete level shifters. |
| Ioff partial-power-down | Disables outputs when VCC = 0V, blocking damaging back-current flow - critical for hot-swap, modular, or multi-rail power systems. |
| Ultra-small DRL package | 1.6mm × 1.6mm footprint with 0.5mm pitch fits high-density layouts in space-constrained applications such as wireless headsets and SSD modules. |
| ESD robustness | 2000V HBM, 1000V CDM, and 200V MM ratings meet industrial handling requirements and reduce field failure risk during assembly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DBVRG4 | SOT-23-5 (DBV) package: 2.9mm × 2.8mm body, larger footprint than DRL; identical electrical specs and pinout. | Preferred where legacy SMT tooling or hand-soldering accessibility is prioritized over board area. | Select DBVRG4 when layout constraints allow larger package and thermal dissipation requirements exceed DRL's 350°C/W RθJA. |
| SN74LVC1G17DCKRG4 | SC70-5 (DCK) package: 2.0mm × 2.1mm body; slightly larger than DRL but offers better thermal performance (RθJA = 371°C/W vs. 350°C/W). | Better suited for thermally demanding environments where ambient exceeds 85°C and airflow is limited. | Choose DCKRG4 when board-level thermal management favors SC70's improved pad exposure and solder joint reliability. |
Compared with SN74LVC1G17DRLRG4, the DBVRG4 offers easier rework and higher thermal mass but consumes 3.5× more PCB area, while the DCKRG4 trades marginal thermal improvement for reduced miniaturization - making DRL the optimal choice for ultra-compact, battery-powered designs requiring minimal footprint and lowest Icc.

FAQ
What is the function of SN74LVC1G17DRLRG4?
The SN74LVC1G17DRLRG4 is a single noninverting Schmitt-trigger buffer performing Y = A. Its hysteresis (0.59V typ at 3V) rejects noise on slow or noisy inputs, making it ideal for switch debouncing, clock conditioning, and interface signal cleanup in portable electronics. It operates from 1.65V to 5.5V and supports Ioff for partial-power-down.
Does SN74LVC1G17DRLRG4 support 5V input signals while powered from 3.3V?
Yes. SN74LVC1G17DRLRG4 inputs tolerate voltages up to 5.5V regardless of VCC, enabling direct 5V-to-3.3V level translation without external components. This is confirmed in the Recommended Operating Conditions table, where VI(max) = 5.5V applies across the full VCC range (1.65V–5.5V).
What is the maximum output drive capability of SN74LVC1G17DRLRG4?
SN74LVC1G17DRLRG4 delivers ±24mA output drive at VCC = 3.3V, as specified in the Recommended Operating Conditions table. This allows driving multiple LVC loads, moderate PCB traces, or small LEDs directly - verified under −40°C to 125°C conditions with no derating required.
Can SN74LVC1G17DRLRG4 be used in hot-swap applications?
Yes. SN74LVC1G17DRLRG4 includes Ioff circuitry that disables outputs when VCC = 0V, preventing back-current flow from live inputs or outputs into a powered-down system. This feature is explicitly validated per JESD78 Class II latch-up and supports safe live insertion in modular or field-upgradeable hardware.
