Product details
Overview
SN74LVC1G17DCKTE4 from Texas Instruments is a single Schmitt-trigger buffer IC designed for 1.65V to 5.5V VCC operation, delivering 24mA output drive at 3.3V, 4.6ns maximum propagation delay, and 5.5V-tolerant inputs. It performs Y = A logic with hysteresis (ΔVT = 0.64V typical at 3V), enabling robust noise immunity in signal conditioning applications such as audio dock interfaces and SSD power sequencing.
For engineers reviewing the SN74LVC1G17DCKTE4 datasheet, SN74LVC1G17DCKTE4 pinout, SN74LVC1G17DCKTE4 application, or SN74LVC1G17DCKTE4 equivalent, key selection criteria include its SC70-5 package footprint (2.0mm × 2.1mm), Ioff support for live insertion, ±24mA drive capability, and guaranteed operation across –40°C to 125°C.
Technical Context
The SN74LVC1G17DCKTE4 implements a noninverting Schmitt-trigger buffer with distinct positive-going (VT+ = 1.48V) and negative-going (VT– = 0.89V) input thresholds at 3V VCC, yielding 0.59V hysteresis. Its CMOS architecture enables rail-to-rail output swing and supports voltage translation from 5.5V inputs down to lower VCC levels.
It features Ioff circuitry that disables outputs when VCC = 0V, preventing back-drive current and supporting partial-power-down modes. Absolute maximum ratings include 6.5V on VCC, inputs, and outputs, with latch-up immunity exceeding 100mA per JESD78 Class II.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - supports mixed-voltage system interfacing and level translation |
| Propagation Delay (tpd) | 4.6ns max at 3.3V, CL = 15pF - enables reliable operation up to ~100MHz signal conditioning |
| Output Drive | ±24mA at 3.3V - sufficient to drive multiple LVC loads or light capacitive loads without buffering |
| Input Voltage Tolerance | 0V to 5.5V - allows 5V logic signals to interface safely with 1.8V/2.5V/3.3V systems |
| Hysteresis (ΔVT) | 0.51V min at 3V VCC - rejects noise on slow-rising/falling signals in audio and sensor paths |
| ICC (max) | 10μA - ultra-low static power for battery-powered portable devices like MP3 players and wireless headsets |
| ESD Rating (HBM) | ±2000V - meets industrial handling requirements without additional protection circuitry |
Pinout & Package
SN74LVC1G17DCKTE4 uses the SC70-5 (DCK) package: 2.0mm × 2.1mm body size, 0.65mm nominal thickness, 5-pin surface-mount with 0.65mm pitch. Pin 1 is marked by a dot; device orientation follows JEDEC MO-203-DA standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all internal circuitry and output return path |
| 2 | A | Noninverting Schmitt-trigger input - accepts 0–5.5V signals regardless of VCC |
| 3 | N.C. | No internal connection - must be left unconnected or tied to GND/VCC per layout guidelines |
| 4 | Y | Buffered, hysteresis-filtered output - rail-to-rail CMOS swing referenced to VCC/GND |
| 5 | VCC | Power supply terminal - bypass with 0.1μF capacitor placed adjacent to pin for noise suppression |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.65V–5.5V) | Enables use across legacy 5V, modern 3.3V/2.5V, and low-power 1.8V systems without redesign |
| Ioff partial-power-down | Prevents damaging back-current flow when VCC is off - essential for hot-swap and modular subsystems |
| 5.5V-tolerant inputs | Eliminates need for external level shifters when interfacing higher-voltage controllers to low-VCC logic |
| Schmitt-trigger hysteresis | Rejects noise on slow or noisy signals (e.g., mechanical switch debouncing, analog sensor outputs) |
| Ultra-small SC70-5 package | 0.64mm² footprint saves PCB area in space-constrained portable electronics like tablets and SSD modules |

FAQ
What is the maximum operating temperature for SN74LVC1G17DCKTE4?
The SN74LVC1G17DCKTE4 is fully specified for operation from –40°C to +125°C ambient temperature. This extended range is validated across all electrical parameters including propagation delay, output drive, and hysteresis, making SN74LVC1G17DCKTE4 suitable for under-hood automotive accessories and industrial SSD modules where thermal margins are critical.
Does SN74LVC1G17DCKTE4 support 5V input signals when powered at 1.8V?
Yes, SN74LVC1G17DCKTE4 supports input voltages up to 5.5V independent of VCC, enabling direct interfacing of 5V microcontrollers or sensors with 1.8V logic domains. This is achieved through TI's overvoltage-tolerant input structure - no external clamping or level-shifting components are required when using SN74LVC1G17DCKTE4 in mixed-voltage systems.
What is the purpose of the N.C. pin on SN74LVC1G17DCKTE4?
Pin 3 of SN74LVC1G17DCKTE4 is designated N.C. (No internal connection). It must remain unconnected in the PCB layout - tying it to VCC or GND is unnecessary and may violate JEDEC SC70 mechanical clearance rules. The N.C. pin exists solely for package symmetry and does not affect SN74LVC1G17DCKTE4 functionality or timing behavior.
How does the Schmitt-trigger action improve noise immunity in SN74LVC1G17DCKTE4?
SN74LVC1G17DCKTE4 uses asymmetric input thresholds (e.g., VT+ = 1.48V, VT– = 0.89V at 3V) to create 0.59V hysteresis. This prevents multiple output transitions when input signals cross the threshold slowly or contain noise spikes - a key advantage over standard buffers in applications like mechanical switch debouncing or IR receiver front-ends where SN74LVC1G17DCKTE4 ensures single, clean edge generation.
Is SN74LVC1G17DCKTE4 compatible with lead-free reflow processes?
Yes, SN74LVC1G17DCKTE4 is RoHS-compliant and rated for lead-free reflow with MSL Level-1 (260°C peak, unlimited floor life). Its NIPDAU lead finish and SC70 package meet IPC/JEDEC J-STD-020D requirements, allowing standard Pb-free solder profiles without special prebake or moisture sensitivity handling - simplifying manufacturing for SN74LVC1G17DCKTE4 integration.
