Product details
Overview
SN74LVC1G07DCKTG4 from Texas Instruments is a single non-inverting buffer/driver with open-drain output, designed for 1.65V–5.5V VCC operation. It delivers 32mA sink current at 4.5V, supports 5.5V-tolerant inputs/outputs, and achieves 4.2ns max propagation delay at 3.3V - enabling wired-OR logic and level translation in space-constrained consumer electronics interfaces.
For engineers reviewing the SN74LVC1G07DCKTG4 datasheet, SN74LVC1G07DCKTG4 pinout, SN74LVC1G07DCKTG4 application, or SN74LVC1G07DCKTG4 equivalent, key selection criteria include open-drain drive capability, Ioff partial-power-down support, 0.5mm-pitch SC70-5 package compatibility, and 5.5V input tolerance across 1.65–5.5V supply range.
Technical Context
The SN74LVC1G07DCKTG4 implements a single CMOS buffer with true open-drain output architecture, requiring an external pull-up to define high-level voltage. Its Ioff circuitry actively disables outputs when VCC = 0V, preventing back-drive current and supporting live insertion in powered systems.
It operates across –40°C to 125°C ambient temperature (SC70 package), accepts input voltages up to 5.5V independent of VCC, and maintains specified switching performance (tpd ≤ 4.7ns at 3.3V, –40°C to 125°C) while consuming ≤10µA ICC in static conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - enables direct interface with 1.8V, 2.5V, 3.3V, and 5V logic domains without level shifters. |
| Max Sink Current (IOL) | 32mA at VCC = 4.5V - sufficient to drive LEDs, relays, or multiple standard TTL loads directly. |
| Propagation Delay (tpd) | 4.2ns max at VCC = 3.3V, 25°C - supports signal integrity in >100MHz digital control paths. |
| Ioff Current | ±10µA max at VCC = 0V - ensures safe hot-plug operation and prevents back-current damage during partial power-down. |
| Input Voltage Tolerance | Up to 5.5V regardless of VCC - allows robust interfacing with higher-voltage peripherals or legacy buses. |
| ESD Rating (HBM) | 2000V - meets JEDEC JESD22-A114A for reliable handling in standard manufacturing environments. |
Pinout & Package
SN74LVC1G07DCKTG4 uses the SC70-5 (DCK) package: 2.0mm × 2.1mm body size, 0.65mm height, 0.5mm lead pitch, and 5-terminal configuration with no internal connection on Pin 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No internal connection | Must be left unconnected; no electrical function or thermal path. |
| 2 (A) | Input | CMOS-compatible digital input accepting 0–5.5V; controls open-drain output state. |
| 3 (GND) | Ground reference | Primary return path for output sink current and internal logic; must be low-impedance. |
| 4 (Y) | Open-drain output | Active-low output requiring external pull-up; sinks up to 32mA when driven low. |
| 5 (VCC) | Power supply | Supplies core logic and output driver; bypass capacitor (0.1µF) required adjacent to this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small SC70-5 footprint | 2.0mm × 2.1mm body saves PCB area vs. SOT-23 while maintaining manufacturable 0.5mm pitch. |
| 5.5V-tolerant I/O | Enables direct connection to 5V peripherals without external clamping or translation circuitry. |
| Ioff partial-power-down | Prevents destructive back-current flow when VCC is off, critical for modular or hot-swap subsystems. |
| Wired-OR/AND logic support | Open-drain output allows connection to shared bus lines for active-low arbitration or status aggregation. |
| Low static power | 10µA max ICC enables use in always-on monitoring circuits without compromising battery life. |

FAQ
What is the maximum sink current capability of the SN74LVC1G07DCKTG4?
The SN74LVC1G07DCKTG4 provides up to 32mA sink current at VCC = 4.5V, as specified in the Absolute Maximum Ratings table. This value is validated across –40°C to 125°C ambient temperature and supports direct LED driving or wired-OR bus termination without external amplification. The SN74LVC1G07DCKTG4 maintains this capability while staying within its 50mA continuous output current limit.
Does the SN74LVC1G07DCKTG4 support level translation between different voltage domains?
Yes, the SN74LVC1G07DCKTG4 supports bidirectional level translation: its inputs accept voltages up to 5.5V regardless of VCC, and its open-drain output can be pulled up to any voltage ≤5.5V. This allows it to translate 1.8V logic high to a 5V bus line or interface a 3.3V microcontroller with 5V peripherals - all while maintaining full timing specifications. The SN74LVC1G07DCKTG4 does not require external biasing for this function.
How does the Ioff feature of the SN74LVC1G07DCKTG4 protect the system during partial power-down?
The Ioff circuitry in the SN74LVC1G07DCKTG4 disables both input and output buffers when VCC = 0V, limiting leakage current to ±10µA. This prevents damaging back-current flow from powered sections into unpowered ones - essential for hot-swap modules, docking stations, or multi-rail systems. The SN74LVC1G07DCKTG4 remains electrically isolated even when inputs or outputs are held at 5.5V during power-off states.
What is the recommended bypass capacitor for the SN74LVC1G07DCKTG4?
A 0.1µF ceramic capacitor is recommended for the SN74LVC1G07DCKTG4 VCC pin, placed as close as possible to the pin with minimal trace length. This value is specified in TI's Layout Guidelines (Section 8.3) to suppress high-frequency noise and stabilize supply voltage during fast output transitions. For systems with multiple logic devices, paralleling a 1µF capacitor may further improve low-frequency decoupling - but the 0.1µF cap is mandatory for SN74LVC1G07DCKTG4 reliability.
Can the SN74LVC1G07DCKTG4 be used in wired-AND configurations?
Yes - the SN74LVC1G07DCKTG4's open-drain output enables wired-AND when multiple outputs share a common pull-up resistor. In this configuration, the bus goes low only if all drivers assert low; otherwise, the pull-up holds it high. This is explicitly supported per TI's Functional Description (Section 7.1), and the SN74LVC1G07DCKTG4's 32mA sink capability ensures robust low-state voltage (<0.55V) even under worst-case loading conditions.
