Product details
Overview
74LVC1G374DCKRG4 from Texas Instruments is a single D-type flip-flop with 3-state output, designed for 1.65-V to 5.5-V operation in space-constrained digital interfaces. It features ±24-mA drive at 3.3 V, 4 ns max propagation delay, and Ioff support for live insertion-enabling use in bidirectional bus drivers and I/O port buffers in portable and industrial control systems.
For engineers reviewing the 74LVC1G374DCKRG4 datasheet, 74LVC1G374DCKRG4 pinout, 74LVC1G374DCKRG4 application, or 74LVC1G374DCKRG4 equivalent, key selection criteria include its SC70-6 package footprint, 3-state enable timing (ten/tdis ≤ 3.8 ns at 3.3 V), low ICC (10 μA max), and compatibility with mixed-voltage signal translation across 1.65–5.5 V rails.
Technical Context
The 74LVC1G374DCKRG4 implements edge-triggered storage on the positive clock transition, with independent buffered output-enable (OE) control that places Q in high-impedance without affecting internal state retention. Its logic operates synchronously with CLK while OE remains asynchronous, allowing data hold or update during bus isolation.
Designed for partial-power-down applications, the device integrates Ioff circuitry that disables outputs and blocks current backflow when VCC = 0 V. Input tolerance up to 5.5 V enables interfacing with higher-voltage controllers while powered from lower VCC rails-supporting down-translation without level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports direct connection to 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains |
| tpd (CLK→Q) | 1.4 ns (typ) / 4 ns (max) at 3.3 V - enables >150 MHz clock operation with tight timing margins |
| Output Drive | ±24 mA at 3.3 V - drives 15 pF loads directly without external buffers in compact PCB layouts |
| Ioff Current | ±10 μA max - prevents damaging back-current during hot-swap or power sequencing |
| Input Voltage Range | –0.5 V to 5.5 V - accepts 5 V TTL inputs even when VCC = 1.8 V, eliminating external translators |
| ESD Rating | 2000-V HBM - meets industrial handling requirements without additional protection circuitry |
Pinout & Package
74LVC1G374DCKRG4 uses the SC70-6 (DCK) package: 2.0 mm × 1.25 mm, 1.1 mm max height, JEDEC MO-203 AB compliant, with gull-wing leads and pin 1 quadrant Q3 orientation per tape-and-reel specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - CLK | Clock input | Positive-edge-triggered latch control; requires minimum pulse width of 2.5 ns at 3.3 V |
| 2 - GND | Ground reference | Return path for all internal logic and output drivers; must be low-inductance connection |
| 3 - D | Data input | Samples on CLK rising edge; setup/hold times as low as 1.5 ns/1.5 ns at 3.3 V |
| 4 - OE | Output-enable control | Active-low; asserts high-impedance Q when high, independent of CLK or D state |
| 5 - Q | 3-state output | Non-inverting registered output; sinks or sources up to 24 mA; high-Z leakage ≤5 μA |
| 6 - VCC | Supply voltage | Power rail for core logic and output drivers; bypass capacitor recommended within 1 cm |
Key Features
| Feature | Design Value |
|---|---|
| NanoFree™ SC70 packaging | Die-as-package construction reduces footprint to 2.5 mm² and eliminates bond wire parasitics |
| Live-insertion support | Ioff circuitry ensures zero back-current during hot-plug events in modular backplane systems |
| Voltage-level translation | 5.5 V-tolerant inputs allow interfacing with legacy 5 V controllers while operating from 1.8 V supply |
| Low dynamic power | 25 pF typical power dissipation capacitance at 10 MHz - minimizes switching noise in RF-sensitive designs |
| High-impedance bus driving | OE-controlled tri-state eliminates need for pull-up resistors or bus contention logic in shared-data lines |
Applications
| Industrial PLC I/O Expansion | Portable Device Power Sequencing |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G374DBVR | SOT-23-6 package (larger 2.92 mm × 1.62 mm footprint; 1.45 mm height); identical electrical specs and pinout | Better thermal dissipation (θJA = 165°C/W vs. 259°C/W) but occupies ~2.3× more board area | Select for higher ambient temperature environments where SC70 thermal limits may be exceeded |
| SN74LVC1G374YZPR | DSBGA-6 (1.4 mm × 1.0 mm; 0.5 mm height); same logic function but ball-grid layout requires different PCB land pattern | Ultra-compact size ideal for wearable or implantable devices; no gull-wing solder joints | Choose when minimizing PCB real estate is critical and assembly supports micro-BGA reflow |

FAQ
What is the maximum clock frequency supported by the 74LVC1G374DCKRG4?
The 74LVC1G374DCKRG4 supports up to 175 MHz maximum clock frequency at 5 V VCC and –40°C to 85°C ambient, with guaranteed minimum 100 MHz operation across the full –40°C to 125°C industrial range. Timing is validated with CL = 15 pF load; performance scales with reduced capacitive loading.
Does the 74LVC1G374DCKRG4 support partial power-down operation?
Yes, the 74LVC1G374DCKRG4 incorporates Ioff circuitry that disables outputs and blocks current backflow when VCC = 0 V, enabling safe live insertion and partial-power-down operation in modular systems. This feature is explicitly characterized per JESD 78 Class II latch-up standards.
Can the 74LVC1G374DCKRG4 interface 5 V inputs while operating from a 1.8 V supply?
Yes, the 74LVC1G374DCKRG4 inputs accept voltages up to 5.5 V regardless of VCC level, enabling direct connection to 5 V logic while powered from 1.8 V. This down-translation capability eliminates external level shifters in mixed-voltage signal paths.
What is the thermal resistance (θJA) of the 74LVC1G374DCKRG4 in its SC70 package?
The 74LVC1G374DCKRG4 in SC70 (DCK) package has a specified junction-to-ambient thermal resistance (θJA) of 259°C/W under standard JEDEC test conditions. This value assumes a 1-inch² copper pad with two vias; actual board-level θJA depends on PCB layout and copper area.
Is the 74LVC1G374DCKRG4 pin-compatible with other members of the SN74LVC1G374 family?
Yes, the 74LVC1G374DCKRG4 shares identical pinout and functionality with SN74LVC1G374DBVR (SOT-23) and SN74LVC1G374YZPR (DSBGA), though package dimensions and land patterns differ. All variants use the same 6-pin assignment: CLK, GND, D, OE, Q, VCC.
