Product details
Overview
SN74AVC16374DGGR 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 operation and featuring Dynamic Output Control (DOC) circuitry, ±24 mA dynamic drive at 2.5 V, and Ioff support for partial-power-down mode. It serves as a bidirectional bus driver or buffer register in high-speed digital interfaces.
For engineers reviewing the SN74AVC16374DGGR datasheet, SN74AVC16374DGGR pinout, SN74AVC16374DGGR application, or SN74AVC16374DGGR equivalent, key selection criteria include its 48-pin TSSOP package, 200 MHz max clock frequency at 1.8 V, 1.4 ns setup time, overvoltage-tolerant I/O (–0.5 V to 4.6 V), and compatibility with mixed-voltage system interconnects.
Technical Context
This device implements two independent 8-bit D-type flip-flops, each with separate clock (CLK) and output-enable (OE) controls. Its DOC circuit dynamically modulates output impedance during signal transitions-lowering it initially for strong drive, then raising it to suppress noise-enabling clean switching without external termination.
The SN74AVC16374DGGR operates across 1.2 V to 3.6 V supply range but is characterized for 1.65–3.6 V use. It supports true 3-state outputs with Ioff protection, allowing safe back-drive prevention during power sequencing, and features input thresholds scaled to VCC (e.g., VIH = 0.65×VCC at 1.65–1.95 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 3.6 V - supports wide voltage interoperability; fully specified from 1.65 V for reliable low-voltage logic interfacing. |
| Max Clock Frequency | 200 MHz at VCC = 1.8 V - enables high-throughput data latching in DDR memory buffers and FPGA I/O expansion. |
| Propagation Delay (tpd) | 3.3 ns at VCC = 3.3 V - ensures tight timing margins in synchronous bus architectures with sub-5 ns critical paths. |
| Dynamic Drive Strength | ±24 mA at 2.5 V - matches standard-output drive capability while maintaining low-noise operation via DOC circuitry. |
| Ioff Current | ±10 µA at VCC = 0 V - prevents damaging current flow during hot-insertion or partial power-down in modular systems. |
| Input/Output Voltage Range | –0.5 V to 4.6 V - allows robust mixed-voltage communication between 1.2 V, 1.8 V, 2.5 V, and 3.3 V domains without level shifters. |
| Static Output Current | ±12 mA at VCC = 3 V - guarantees stable logic-level maintenance under typical load conditions in industrial control backplanes. |
Pinout & Package
TSSOP-48 (DGG) package: 12.6 mm × 6.2 mm × 1.2 mm max height, 0.5 mm pitch, RoHS-compliant NIPDAU finish, MSL Level-1, tape-and-reel (2000 pcs/reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE | Output Enable (active-low) | Independent 8-bit group control; places Q outputs in high-impedance state without affecting internal latch state. |
| 1CLK, 2CLK | Clock input (positive-edge triggered) | Synchronizes data capture on rising edge; each CLK controls one 8-bit section for flexible partitioning. |
| 1D1–1D8, 2D1–2D8 | Data inputs | 16 parallel asynchronous inputs; accept overvoltage-tolerant signals up to 4.6 V regardless of VCC. |
| 1Q1–1Q8, 2Q1–2Q8 | Tri-state outputs | 16 buffered, 3-state outputs with DOC-enhanced slew control; drive buses directly without pull-ups. |
| VCC, GND | Power and ground terminals | Multiple VCC/GND pairs (8 total) minimize switching noise and ensure stable core voltage distribution. |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Output Control (DOC) | Reduces simultaneous switching noise by dynamically adjusting output impedance mid-transition-no external damping components required. |
| Overvoltage-Tolerant I/O | Accepts –0.5 V to 4.6 V input/output voltages across full VCC range, enabling seamless interface between disparate voltage domains. |
| Ioff Partial-Power-Down Support | Disables outputs when VCC = 0 V, preventing reverse current flow during board hot-swap or staged power sequencing. |
| Widebus™ Architecture | Optimized for high-density bus buffering with matched propagation delays and minimized skew across all 16 channels. |
| EPIC™ Submicron CMOS Process | Delivers low static current (40 µA at 3.6 V) and high-speed performance while maintaining robust ESD immunity (>2 kV HBM). |

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 |
|---|---|---|---|
| SN74LVC16374DGGR | Lower drive (±24 mA only at 3.3 V), no DOC circuit, 1.65–3.6 V range only. | Lacks dynamic noise suppression; suitable for cost-sensitive, lower-speed (<100 MHz) applications where EMI is less critical. | Choose when DOC is unnecessary and budget constraints outweigh noise-performance requirements. |
| SN74AVCH16374DGGR | Includes bus-hold circuitry, same DOC and voltage range, but higher ICC (60 µA vs 40 µA at 3.6 V). | Eliminates need for external pull-up/down resistors on unused inputs; adds ~20 µA static current overhead. | Prefer when floating input immunity is required and additional quiescent current is acceptable. |
Compared with SN74LVC16374DGGR and SN74AVCH16374DGGR, the SN74AVC16374DGGR uniquely balances high-frequency capability (200 MHz), active noise control (DOC), and ultra-low Ioff-making it optimal for mixed-voltage, hot-pluggable, and EMI-sensitive embedded systems.

FAQ
What is the maximum clock frequency supported by the SN74AVC16374DGGR?
The SN74AVC16374DGGR supports up to 200 MHz at VCC = 1.8 V and 160 MHz at VCC = 1.5 V, as specified in the timing requirements table. At 3.3 V, the maximum clock frequency is 200 MHz with a minimum pulse width of 2.5 ns. These values are guaranteed across the full –40°C to 85°C operating range and reflect actual measured performance-not typical-only figures.
Does the SN74AVC16374DGGR support partial power-down operation?
Yes, the SN74AVC16374DGGR includes Ioff circuitry that disables outputs when VCC = 0 V, limiting reverse current to ±10 µA. This feature enables safe partial-power-down operation in modular systems, such as hot-pluggable cards or staged power sequencing in industrial controllers-ensuring no damaging back-current flows through the SN74AVC16374DGGR during power transitions.
How does the Dynamic Output Control (DOC) circuit in the SN74AVC16374DGGR reduce noise?
The DOC circuit in the SN74AVC16374DGGR dynamically lowers output impedance at the start of a transition to deliver strong drive, then raises it mid-transition to limit di/dt and suppress simultaneous switching noise. This eliminates the need for external series resistors or RC networks while maintaining full ±24 mA drive capability at 2.5 V-verified in Figure 1 of the SN74AVC16374DGGR datasheet.
What is the input voltage tolerance of the SN74AVC16374DGGR?
The SN74AVC16374DGGR accepts input voltages from –0.5 V to 4.6 V, independent of VCC. This overvoltage tolerance allows direct interfacing between 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters-critical for mixed-voltage system integration. The specification is validated per absolute maximum ratings and confirmed in both recommended operating conditions and electrical characteristics tables.
Is the SN74AVC16374DGGR pin-compatible with other 48-pin TSSOP flip-flops like the SN74LVC16374DGGR?
Yes, the SN74AVC16374DGGR shares identical pinout, footprint, and terminal assignments with SN74LVC16374DGGR and SN74AVCH16374DGGR in the 48-pin TSSOP (DGG) package-as confirmed by TI's official package drawings and logic diagrams. However, functional differences (e.g., DOC presence, Ioff behavior, and drive strength profiles) require validation in the target application before substitution.
