Product details
Overview
SN74LVC1G17DRLR from Texas Instruments is a single-channel Schmitt-trigger buffer IC designed for noise-immune signal conditioning in 1.65V–5.5V systems. It performs Y = A logic, delivers ±24mA output drive at 3.3V, achieves 4.6ns max propagation delay (tpd) at 3.3V/CL=15pF, and supports 5.5V-tolerant inputs - enabling level translation in portable audio and SSD power sequencing applications.
For engineers reviewing the SN74LVC1G17DRLR datasheet, SN74LVC1G17DRLR pinout, SN74LVC1G17DRLR application, or SN74LVC1G17DRLR equivalent, key selection criteria include Schmitt-trigger hysteresis (ΔVT = 0.51–1.04V), Ioff-enabled live insertion, ultra-small DPW package (0.8mm × 0.8mm), and guaranteed operation from –40°C to 125°C.
Technical Context
The SN74LVC1G17DRLR implements a noninverting Schmitt-trigger buffer with asymmetric input thresholds (VT+ = 1.48V, VT– = 0.89V at VCC = 3V), providing 0.59V hysteresis to reject slow-rising or noisy signals. Its CMOS design maintains low static ICC (≤10μA) while delivering rail-to-rail output swing and robust ±24mA drive capability.
It features Ioff circuitry that disables outputs when VCC = 0V, preventing back-drive current during partial power-down - critical for hot-swap interfaces in AV receivers and enterprise SSDs. Input voltage tolerance up to 5.5V allows interfacing with higher-voltage controllers while operating from 1.65V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
The SN74LVC1G17DRLR uses the DRL (SOT-5X3) 5-pin package: 1.6mm × 1.6mm body size, 0.5mm pitch, no exposed pad. Pin 1 is marked with a dot; pin 3 is GND, pin 5 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No internal connection (N.C.) | Unused terminal - must be left floating or tied to GND/VCC per layout guidelines; no electrical function |
| 2 | Input (A) | Schmitt-trigger input accepting 0–5.5V; threshold hysteresis enables reliable switching on noisy or slow-rising signals |
| 3 | Ground (GND) | Reference return path for all internal logic and output drivers; requires low-inductance PCB connection |
| 4 | Output (Y) | Noninverting buffered output with rail-to-rail swing and ±24mA drive; supports fanout to multiple LVC inputs |
| 5 | Power (VCC) | Supply input for core logic and output stage; requires local 0.1μF bypass capacitor placed adjacent to pin |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | Provides 0.51–1.04V hysteresis to eliminate chatter on slow or noisy control lines in audio docks and SSDs |
| 5.5V-tolerant inputs | Allows direct interface with 5V microcontrollers while operating from 1.65V–3.3V supplies - simplifies mixed-voltage designs |
| Ioff partial-power-down | Enables live insertion and hot-swap capability by blocking back-current when VCC = 0V - essential for modular AV receivers |
| Ultra-small DPW/DRL footprint | DRL package occupies only 1.6mm × 1.6mm - saves board space in space-constrained tablets and wireless headsets |
| Wide temperature range | Specified from –40°C to 125°C - supports deployment in telecom AC/DC supplies and enterprise SSD thermal environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DBVR | SOT-23-5 (DBV) package: 2.9mm × 1.6mm body, larger footprint than DRL's 1.6mm × 1.6mm | Better thermal dissipation (RθJA = 357°C/W vs. DRL's 350°C/W) but occupies ~2.3× more board area | Select DBVR for prototyping or where manual rework is preferred; DRL for high-density portable designs |
| NC7SZ17P5X | SC-70-5 package (same pinout), 1.25V–5.5V VCC, 3.5ns tpd at 3.3V, ±24mA drive, but no Ioff support | Lacks Ioff - unsuitable for hot-swap or partial-power-down systems requiring back-drive protection | Choose NC7SZ17P5X only in always-powered, single-rail applications where Ioff is not required |

FAQ
What is the maximum propagation delay of the SN74LVC1G17DRLR at 3.3V?
The SN74LVC1G17DRLR has a maximum propagation delay (tpd) of 4.6ns at VCC = 3.3V, CL = 15pF, and TA = –40°C to 85°C. This value is confirmed in Table 5-2 of the official datasheet and applies directly to the DRL package variant. The SN74LVC1G17DRLR maintains this performance across its full operating temperature range up to 125°C, with tpd ≤ 6.5ns under worst-case conditions.
Does the SN74LVC1G17DRLR support partial power-down operation?
Yes, the SN74LVC1G17DRLR supports partial power-down via its Ioff feature. When VCC = 0V, the Ioff circuitry disables both input and output terminals, limiting leakage to ±10μA and preventing damaging back-current flow. This capability is explicitly validated for the DRL package in Section 5.5 (Electrical Characteristics) and enables safe live insertion in modular AV receivers and SSD carrier boards.
What is the input hysteresis voltage (ΔVT) of the SN74LVC1G17DRLR at 3V supply?
At VCC = 3V, the SN74LVC1G17DRLR exhibits a minimum hysteresis voltage (ΔVT = VT+ – VT–) of 0.51V, with a typical value of 0.83V. This is specified in Table 5-1 (DC Limit Changes) and ensures reliable rejection of noise up to ±255mV on the input signal - critical for stable operation in EMI-prone environments like wireless headsets and tablet displays.
Can the SN74LVC1G17DRLR accept 5V input signals while operating from a 1.8V supply?
Yes, the SN74LVC1G17DRLR accepts input voltages up to 5.5V regardless of VCC, including when powered from 1.8V. This 5.5V-tolerant input is documented in Section 5.3 (Recommended Operating Conditions) and enables level translation from legacy 5V peripherals to modern low-voltage processors - a key feature used in Blu-ray player and HDTV signal routing.
What package type and dimensions does the SN74LVC1G17DRLR use?
The SN74LVC1G17DRLR uses the DRL (SOT-5X3) package: a 5-pin, 0.5mm-pitch surface-mount device with a 1.6mm × 1.6mm body size and 1.6mm × 1.2mm footprint. Mechanical details are confirmed in the "Package Information" table on page 2 of the datasheet and match TI's official DRL package drawing SLMS213.
