Product details
Overview
SN74LVC2G17DCKRE4 from Texas Instruments is a dual Schmitt-trigger buffer IC designed for 1.65 V to 5.5 V operation, featuring hysteresis-enabled noise immunity, ±24-mA output drive at 3.3 V, and Ioff support for live insertion and partial-power-down applications. It performs Y = A logic on two independent channels and is used in audio docks, SSDs, and HDTVs for signal conditioning of noisy or slow-rising control lines.
For engineers reviewing the SN74LVC2G17DCKRE4 datasheet, SN74LVC2G17DCKRE4 pinout, SN74LVC2G17DCKRE4 application, or SN74LVC2G17DCKRE4 equivalent, key selection criteria include Schmitt-trigger input thresholds (VT+ = 2.0 V, VT– = 1.3 V at 3 V), max 5.4 ns propagation delay at 3.3 V, 5.5-V-tolerant inputs, NanoFree™ SC70-6 package footprint, and Ioff-enabled back-drive protection during power sequencing.
Technical Context
This device implements two independent noninverting Schmitt-trigger buffers with asymmetric input thresholds-VT+ and VT– differ by 0.4–1.4 V across VCC range-to reject noise on slow or degraded digital signals. Its Ioff circuitry actively disables outputs when VCC = 0 V, blocking reverse current flow from powered subsystems into unpowered logic.
The SN74LVC2G17DCKRE4 supports voltage translation: inputs tolerate up to 5.5 V regardless of VCC, enabling interfacing between 5-V legacy circuits and 1.8/2.5/3.3-V domains. All outputs are CMOS-compatible with rail-to-rail swing and balanced rise/fall characteristics under 30-pF load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - Enables single-supply operation across 1.8-V, 2.5-V, 3.3-V, and 5-V systems without level shifters. |
| tpd Max | 5.4 ns at VCC = 3.3 V - Supports >100-MHz signal conditioning for button debouncing, reset synchronization, and clock clean-up. |
| Input Threshold Hysteresis ΔVT | 0.4 V to 1.4 V - Provides robust noise margin against EMI, crosstalk, and ground bounce in high-density PCB layouts. |
| Ioff Current | ±10 μA max - Ensures safe hot-plug operation and prevents back-drive damage when interfacing with powered peripherals during system sleep. |
| Output Drive | ±24 mA at 3.3 V - Drives multiple 74LVC inputs or small capacitive loads (e.g., 10-cm PCB traces) without external buffers. |
| Input Voltage Tolerance | Up to 5.5 V - Allows direct connection to 5-V microcontroller GPIOs or legacy ASIC outputs without clamping diodes. |
| ESD Rating | 2000-V HBM - Meets industrial-grade robustness requirements for consumer electronics assembly and field operation. |
Pinout & Package
SN74LVC2G17DCKRE4 uses the SC70-6 (DCK) package: 2.00 mm × 1.25 mm body, 0.65-mm lead pitch, and 0.9-mm max height - optimized for space-constrained portable designs. Pin 1 is marked via laser top-side dot; orientation follows JEDEC MO-203-DA standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Input 1 | Schmitt-triggered input for first buffer channel; accepts 0–5.5 V regardless of VCC. |
| GND | Ground | Reference return path for all internal logic and output drivers; must be low-impedance for stable hysteresis performance. |
| 2A | Input 2 | Independent Schmitt-triggered input for second buffer; electrically isolated from 1A but shares same VCC/GND rails. |
| 1Y | Output 1 | Noninverting buffered output with rail-to-rail swing; capable of sourcing/sinking ±24 mA at 3.3 V. |
| VCC | Power Supply | Single supply pin for both buffers; powers internal logic, Ioff circuitry, and output drivers. |
| 2Y | Output 2 | Second independent noninverting output; identical electrical specs to 1Y; no cross-talk coupling per functional block diagram. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Provides 0.4–1.4 V hysteresis to eliminate chatter on mechanical switch inputs, reset lines, or slow analog comparator outputs. |
| Ioff partial-power-down | Disables outputs and limits leakage to ±10 μA when VCC = 0 V - essential for PCIe hot-plug, USB-C accessory detection, and modular power architectures. |
| 5.5-V tolerant inputs | Eliminates need for external level-shifting components when interfacing 5-V sensors or microcontrollers with 3.3-V or lower logic domains. |
| NanoFree™ SC70-6 package | Die-as-package construction reduces parasitic inductance/capacitance - improves signal integrity and enables <1.3-mm board area per channel. |
| Low ICC (10 μA max) | Minimizes quiescent power in always-on monitoring circuits such as battery-backed real-time clocks or wake-on-LAN controllers. |

FAQ
What is the maximum operating temperature for SN74LVC2G17DCKRE4?
The SN74LVC2G17DCKRE4 is rated for operation from –40°C to +125°C ambient temperature, as specified in the Recommended Operating Conditions table. This extended range supports deployment in automotive cabin modules, industrial motor drives, and outdoor-connected devices where thermal cycling exceeds commercial-grade limits.
Does SN74LVC2G17DCKRE4 support 5-V input signals when powered at 3.3 V?
Yes, SN74LVC2G17DCKRE4 features 5.5-V-tolerant inputs - its inputs accept voltages up to 5.5 V regardless of VCC level. When powered at 3.3 V, it safely interfaces with 5-V microcontrollers or legacy peripherals without external clamping or level-shifting circuitry.
How does the Ioff feature function in SN74LVC2G17DCKRE4?
The Ioff circuitry in SN74LVC2G17DCKRE4 automatically disables both outputs when VCC is at 0 V or disconnected, limiting I/O leakage to ±10 μA. This prevents damaging back-current flow from powered downstream circuits into the unpowered SN74LVC2G17DCKRE4 - critical for hot-swap and modular power architectures.
What is the typical propagation delay of SN74LVC2G17DCKRE4 at 3.3 V?
At VCC = 3.3 V and TA = 25°C, the typical propagation delay (tpd) of SN74LVC2G17DCKRE4 is 3.5 ns, with a maximum of 5.4 ns over –40°C to +85°C. This ensures deterministic timing for high-speed signal conditioning in SSD power sequencing and HDMI CEC interfaces.
Can SN74LVC2G17DCKRE4 replace SN74LVC2G17DBVR in an existing design?
Yes, SN74LVC2G17DCKRE4 is functionally and electrically identical to SN74LVC2G17DBVR, differing only in package (SC70-6 vs SOT-23-6). Pinout is identical, but the smaller SC70 footprint requires PCB layout revision - no schematic changes are needed for drop-in replacement where space permits.
