Product details
Overview
SN74LVC16374DGG from Texas Instruments is a 16-bit edge-triggered D-type flip-flop with 3-state outputs, designed for 1.65-V to 3.6-V VCC operation. It functions as a dual 8-bit or single 16-bit register for data latching and bus interfacing, featuring ±24 mA output drive at 3 V, 150 MHz maximum clock frequency, and Ioff support for partial-power-down mode.
For engineers reviewing the SN74LVC16374DGG datasheet, SN74LVC16374DGG pinout, SN74LVC16374DGG application, or SN74LVC16374DGG equivalent, this page delivers verified technical context, real-world timing behavior, package-specific terminal mapping, and validated alternative options for industrial bus buffering, I/O expansion, and mixed-voltage level translation.
Technical Context
This device implements two independent 8-bit positive-edge-triggered D-type flip-flop banks, each with dedicated clock (1CLK/2CLK) and output-enable (1OE/2OE) controls. Data propagation occurs on the rising edge of CLK, with setup/hold times as low as 1.9 ns (VCC = 3.3 V) and propagation delay ≤4.5 ns.
Its 3-state outputs support high-impedance bus driving without pull-ups, while Ioff circuitry blocks current backflow during power-down. Input tolerance up to 5.5 V enables direct interfacing with 5-V logic in 3.3-V systems - a confirmed mixed-mode signal capability per TI's specification table.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 3.6 V - Enables operation across low-voltage embedded rails including 1.8 V, 2.5 V, and 3.3 V systems. |
| Max Clock Frequency | 150 MHz - Supports high-speed data capture in memory interfaces and synchronous bus controllers. |
| Output Drive | ±24 mA at VCC = 3 V - Sufficient to directly drive standard CMOS loads and short PCB traces without buffers. |
| tsu / th (VCC = 3.3 V) | 1.9 ns / 1.1 ns - Tight timing margins allow reliable operation in fast-clocked FPGA-to-ASIC interconnects. |
| Ioff Current | ±10 µA at VI/VO = 5.5 V - Ensures safe isolation during hot-swap or partial-power-down sequences. |
| Input Voltage Range | –0.5 V to 5.5 V - Permits 5-V-tolerant inputs in mixed-voltage designs without external level shifters. |
| Power Dissipation Cap. | 58 pF per flip-flop (VCC = 3.3 V) - Predictable dynamic loading for accurate power budgeting in dense logic arrays. |
Pinout & Package
TSSOP-48 package (DGG), 12.5 mm × 6.1 mm body, 0.5 mm pitch, JEDEC MO-153 compliant. Pin 1 located at top-left corner (Q1 quadrant), marked by beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE | Output Enable (active-low) | Independent control of each 8-bit bank's output state; does not affect internal latch operation. |
| 1CLK, 2CLK | Clock input (positive edge) | Edge-triggered sampling of D inputs; asynchronous reset not supported. |
| 1D1–1D8, 2D1–2D8 | Data inputs | 16 total inputs accepting 1.65–5.5 V signals; no internal pull-ups/pull-downs. |
| 1Q1–1Q8, 2Q1–2Q8 | Tri-state outputs | Driven high/low or placed in high-Z; output contention avoided when OE = high. |
| VCC, GND | Supply terminals | Two VCC and three GND pins distributed for low-noise power delivery and reduced ground bounce. |
Key Features
| Feature | Design Value |
|---|---|
| Mixed-voltage interface | 5-V-tolerant inputs with 3.3-V VCC enable direct connection to legacy 5-V peripherals without translators. |
| Partial-power-down support | Ioff limits reverse current to ±10 µA when powered down, protecting live backplane buses. |
| Low ground bounce | VOLP < 0.8 V at VCC = 3.3 V ensures signal integrity during simultaneous output switching. |
| Bus-friendly 3-state control | OE-independent internal latching allows data retention or update while outputs remain high-Z. |
| JEDEC-standard timing | Specified tsu/th/tPD across 1.65–3.6 V range simplifies timing closure in multi-rail designs. |
Applications
| Industrial PLC I/O Expansion | Memory Interface Buffering |
|---|---|
Use Scenario: Expanding GPIO count on a microcontroller-based PLC rack with isolated 24-V field-side drivers. IC Role / Device Role / Timing Role: Acts as an 16-bit synchronized input latch and output register, isolating MCU timing from field-side noise. Use Value: 150 MHz clock tolerance supports fast scan cycles; Ioff prevents backfeed into unpowered modules during hot-swap maintenance. |
Use Scenario: Buffering address/data lines between an FPGA and parallel NOR flash in a test equipment controller. IC Role / Device Role / Timing Role: Provides edge-aligned data staging and bus contention control during read/write transitions. Use Value: 4.5 ns tPD and 1.9 ns tsu ensure setup compliance at 66 MHz bus speeds; 3-state outputs eliminate need for external bus switches. |
| FPGA-to-ASIC Communication Bridge | Mixed-Voltage Sensor Hub |
Use Scenario: Interfacing a 3.3-V FPGA to a 5-V ASIC in a radar signal processor backplane. IC Role / Device Role / Timing Role: Translates and synchronizes control/status signals across voltage domains with deterministic latency. Use Value: 5.5-V input tolerance eliminates level-shifter ICs; tight 1.1 ns th guarantees hold-time margin under jitter. |
Use Scenario: Aggregating digital outputs from multiple analog sensor front-ends (some 5-V, some 3.3-V) into a single MCU interface. IC Role / Device Role / Timing Role: Serves as a voltage-agnostic input capture register with common clock domain alignment. Use Value: Single-supply 3.3-V operation with 5-V-tolerant inputs reduces BOM count; low ICC (20 µA) extends battery life in portable units. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ALVC16374DGG | Higher drive (±24 mA vs ±12 mA at 3.3 V), lower VOLP (0.5 V typical), but narrower VCC range (2.3–3.6 V). | Preferred where higher noise immunity and faster edge rates are required, but incompatible with 1.8-V systems. | Select SN74ALVC16374DGG only if operating exclusively above 2.3 V and requiring tighter ground-bounce control. |
| 74LVCH16374ADGG | Includes bus-hold circuitry on all I/Os; identical VCC range and timing, but higher ICC (40 µA typical). | Suitable for floating-input environments (e.g., unpopulated daughterboards); adds ~0.5 ns to tPD. | Choose 74LVCH16374ADGG when inputs may be unterminated during configuration or debug phases. |
Compared with SN74LVC16374DGG, SN74ALVC16374DGG trades 1.65-V compatibility for enhanced drive/noise performance, while 74LVCH16374ADGG adds bus-hold robustness at the cost of static current and marginal timing penalty - both require layout verification due to non-pin-compatible thermal pads and slightly different pinouts.

FAQ
What is the maximum clock frequency supported by the SN74LVC16374DGG?
The SN74LVC16374DGG supports a maximum clock frequency of 150 MHz across its full VCC range (1.65 V to 3.6 V), as specified in the Timing Requirements table of the official datasheet. This value is guaranteed under recommended operating conditions and applies to both 8-bit banks simultaneously.
Does the SN74LVC16374DGG support 5-V input signals while operating at 3.3-V VCC?
Yes, the SN74LVC16374DGG supports 5-V-tolerant inputs with VCC as low as 1.65 V. Its input voltage range is specified from –0.5 V to 5.5 V, enabling direct connection to 5-V logic families without external level shifters - a confirmed feature in the "Mixed-Mode Signal Operation" section.
How does the Ioff feature function in the SN74LVC16374DGG?
The Ioff feature in the SN74LVC16374DGG disables output buffers when VCC = 0 V, limiting reverse current to ±10 µA even if 5.5 V is applied to I/O pins. This prevents damaging current backflow during partial-power-down or hot-swap events, as verified in the Electrical Characteristics table.
What package type and dimensions does the SN74LVC16374DGG use?
The SN74LVC16374DGG uses a TSSOP-48 package (DGG), measuring 12.5 mm × 6.1 mm with 0.5 mm lead pitch. It complies with JEDEC MO-153 and features a gage plane height of 1.20 mm max, as documented in TI's mechanical drawing MTSS003D.
Can the SN74LVC16374DGG be used as two independent 8-bit registers?
Yes, the SN74LVC16374DGG is explicitly designed to operate as two independent 8-bit D-type flip-flops, with separate clock (1CLK/2CLK) and output-enable (1OE/2OE) controls. The functional description confirms this dual-bank architecture and its use in bidirectional bus drivers and I/O ports.
