Product details

Overview

SN74LVC1G17DRYR from Texas Instruments is a single-channel Schmitt-trigger buffer IC designed for signal conditioning in noise-prone digital interfaces. It operates across 1.65V–5.5V V_CC, delivers ±24mA output drive at 3.3V, achieves 4.6ns max propagation delay, and features 5.5V-tolerant inputs - enabling level translation in portable audio and SSD power sequencing circuits.

For engineers reviewing the SN74LVC1G17DRYR datasheet, SN74LVC1G17DRYR pinout, SN74LVC1G17DRYR application, or SN74LVC1G17DRYR equivalent, key selection criteria include its ultra-compact USON-6 (DRY) package, I_off support for live insertion, hysteresis thresholds (VT+ = 2.74V / VT− = 1.97V at 4.5V), and guaranteed operation from −40°C to +125°C.

Technical Context

The SN74LVC1G17DRYR implements a non-inverting Schmitt-trigger buffer (Y = A) with asymmetric input thresholds to reject slow-rising or noisy signals. Its CMOS design maintains low static current (≤10μA ICC) while supporting rail-to-rail output swing and 5.5V input tolerance independent of V_CC.

It integrates I_off circuitry that disables outputs and blocks current backflow when V_CC = 0V, enabling safe partial-power-down operation in multi-rail systems. The device meets JESD78 Class II latch-up immunity (>100mA) and exceeds JEDEC ESD standards: ±2000V HBM, ±1000V CDM.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	1.65V to 5.5V - supports mixed-voltage system interfacing and battery-powered operation down to 1.65V logic.
Propagation Delay (t_pd)	4.6ns max at 3.3V, CL = 15pF - enables reliable timing in ≤100MHz digital paths with clean edge integrity.
Output Drive	±24mA at 3.3V - drives multiple LVC loads or resistive terminations without external buffers.
Hysteresis (ΔV_T)	0.93V at 4.5V V_CC - rejects up to ~930mV of input noise on slow edges, critical for push-button or sensor debouncing.
I_off	±10μA max at 5.5V - prevents back-drive damage during hot-swap or power sequencing in modular systems.
Input Voltage Tolerance	0V to 5.5V - allows interfacing with 5V peripherals while powered from 1.8V/2.5V/3.3V rails.
Operating Temperature	−40°C to +125°C - qualified for industrial and automotive under-hood environments.

Pinout & Package

SN74LVC1G17DRYR uses the 6-pin USON (DRY) package: 1.45mm × 1.0mm body, 0.5mm pitch, wettable flank terminals. Pin 1 is marked by a dot; pins 2–6 are assigned as follows:

Pin/Terminal	Circuit Role	Design Meaning
1	A	Non-inverting Schmitt-trigger input - accepts 0–5.5V signals regardless of V_CC level.
2	N.C.	No internal connection - must be left floating or tied to GND/V_CC; no electrical function.
3	N.C.	No internal connection - same as Pin 2; no routing or termination required.
4	GND	Ground reference - connects to system ground plane; critical for noise immunity and thermal dissipation.
5	Y	Buffered output - delivers full-rail CMOS levels with ±24mA drive capability at 3.3V.
6	V_CC	Power supply - supplies core logic; bypass capacitor (0.1μF) required adjacent to this pin.

Key Features

Feature	Design Value
Schmitt-trigger input	Provides 0.93V hysteresis at 4.5V - eliminates chatter on slow or noisy control lines like reset or enable signals.
I_off protection	Enables live insertion and partial-power-down - prevents current backflow when V_CC is off but inputs/outputs remain active.
5.5V-tolerant inputs	Allows direct interface with legacy 5V logic without level shifters - reduces BOM count in mixed-voltage designs.
Ultra-small USON-6 package	1.45mm × 1.0mm footprint - saves >60% board area vs. SOT-23, ideal for space-constrained portable SSDs and headsets.
Low ICC	10μA maximum quiescent current - extends battery life in always-on audio dock and PDA applications.

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 package (2.9mm × 1.6mm); 5-pin layout; no Pin 2/3 N.C. - requires PCB redesign.	Better thermal performance (R_θJA = 357°C/W vs. 608°C/W) but larger footprint - suited for thermally demanding, less space-constrained designs.	Select DBVR when board area is secondary to thermal margin and standard pick-and-place compatibility is preferred.
SN74LVC1G17DCKR	SC70-5 package (2.0mm × 1.25mm); 5-pin; shares same functional specs but lacks Pin 2/3 N.C. - different pinout and smaller than DRY.	Higher density than SOT-23 but lower integration than USON-6 - used where 5-pin count simplifies routing but miniaturization remains critical.	Select DCKR when existing SC70 footprints exist or when 5-pin simplicity outweighs the need for I_off-optimized 6-pin layout.

Compared with SN74LVC1G17DBVR and SN74LVC1G17DCKR, the SN74LVC1G17DRYR offers the smallest footprint (1.45mm × 1.0mm) and dedicated N.C. pins for mechanical stability in ultra-thin devices, though with higher thermal resistance - making it optimal for portable consumer electronics where size dominates thermal budget.

FAQ

What is the function of the two N.C. pins on SN74LVC1G17DRYR?

The SN74LVC1G17DRYR has two no-connect (N.C.) pins - Pins 2 and 3 - which are electrically unconnected internally. They serve mechanical stabilization in the USON-6 package and may be left floating or tied to GND/V_CC for improved solder joint reliability; neither affects logic operation of the SN74LVC1G17DRYR.

Does SN74LVC1G17DRYR support true 5V operation?

Yes, SN74LVC1G17DRYR supports V_CC up to 5.5V and operates fully specified from 1.65V to 5.5V. At 5V V_CC, it delivers 4.4ns max t_pd, ±32mA output drive, and maintains 5.5V input tolerance - confirming robust 5V-system compatibility for the SN74LVC1G17DRYR.

How does the Schmitt-trigger action benefit SN74LVC1G17DRYR in noisy environments?

The SN74LVC1G17DRYR provides 0.93V hysteresis at 4.5V V_CC, meaning its positive-going threshold (VT+) is 2.74V and negative-going (VT−) is 1.97V. This gap rejects noise spikes ≤930mV, preventing false triggering on slow or noisy signals - a key advantage of the SN74LVC1G17DRYR in EMI-heavy applications like wireless headsets.

Can SN74LVC1G17DRYR be used for level translation between 5V and 3.3V systems?

Yes, SN74LVC1G17DRYR enables unidirectional level translation: its 5.5V-tolerant inputs accept 5V signals while operating from a 3.3V V_CC, and its output swings rail-to-rail (0V/3.3V). This makes the SN74LVC1G17DRYR ideal for interfacing 5V sensors or legacy peripherals with 3.3V microcontrollers.

What is the significance of I_off in SN74LVC1G17DRYR for system design?

I_off in SN74LVC1G17DRYR disables output drivers and blocks current flow when V_CC = 0V, allowing safe live insertion into powered-backplane systems or partial power-down of subsystems. This protects both the SN74LVC1G17DRYR and upstream/downstream components from damaging back-current - essential in modular SSD and docking station designs.
