Product details
Overview
SN74AVC16374ZQLR 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 and featuring Dynamic Output Control (DOC) circuitry. It delivers ±24 mA dynamic drive at 2.5 V, supports mixed-voltage-mode data communications via overvoltage-tolerant I/O, and enables partial-power-down mode via Ioff. It is used in bidirectional bus drivers and I/O port buffering in high-speed digital systems.
For engineers reviewing the SN74AVC16374ZQLR datasheet, SN74AVC16374ZQLR pinout, SN74AVC16374ZQLR application, or SN74AVC16374ZQLR equivalent, key selection criteria include its 16-bit dual-8-bit configurable architecture, DOC-enabled noise reduction, 1.65–3.6 V supply range, −40°C to 85°C operating temperature, and VFBGA-48 (GQL) package compatibility with high-density PCB layouts.
Technical Context
This device implements two independent 8-bit edge-triggered D-type flip-flops sharing common clock and output-enable controls. Each section operates synchronously on the rising edge of CLK, latching D inputs to Q outputs while OE determines 3-state output behavior-normal logic levels when low, high-impedance when high. Internal Ioff circuitry disables outputs during power-down to prevent backflow current.
The Dynamic Output Control (DOC) circuit dynamically modulates output impedance: lowering it at signal transition onset for strong drive (equivalent to ±24 mA standard outputs at 2.5 V), then raising it mid-transition to suppress switching noise. This occurs without sacrificing propagation delay, which remains as low as 3.3 ns at 3.3 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 3.6 V - Enables interoperability across 1.8 V, 2.5 V, and 3.3 V domains without level shifters. |
| Max Clock Frequency | 200 MHz at 3.3 V - Supports high-throughput data latching in memory interfaces and bus buffers. |
| tpd (CLK→Q) | 3.3 ns typical at 3.3 V - Ensures tight timing margins in synchronous logic chains with minimal skew. |
| Ioff Current | ±10 µA max - Guarantees safe partial-power-down operation with no damaging back-current during VCC ramp-down. |
| VOH / VOL | VOH ≥ 2.3 V, VOL ≤ 0.7 V at 3 V/12 mA - Meets TTL and CMOS logic thresholds for reliable interfacing. |
| Input Voltage Range | −0.5 V to 4.6 V - Allows overvoltage-tolerant operation for mixed-supply system robustness. |
| Dynamic Drive | Equivalent to ±24 mA standard outputs at 2.5 V - Delivers bus-driving capability without external buffers. |
Pinout & Package
VFBGA-48 (GQL) package, 5.5 mm × 5.5 mm, 0.5 mm pitch, bottom-side ball array, JEDEC MO-220 compliant. Designed for space-constrained, high-I/O-count applications requiring fine-pitch BGA assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE | Output enable (active-low) | Independently places first/second 8-bit bank into high-Z; no effect on internal latch state. |
| 1CLK, 2CLK | Clock input (rising-edge sensitive) | Triggers simultaneous capture of all eight D inputs per bank on positive transition. |
| 1D1–1D8, 2D1–2D8 | Data inputs | Asynchronous inputs latched only on CLK↑; tolerate voltages up to 4.6 V regardless of VCC. |
| 1Q1–1Q8, 2Q1–2Q8 | Tri-state outputs | Driven low/high or high-Z based on OE; DOC circuit reduces simultaneous switching noise. |
| VCC, GND | Power and ground | Multiple VCC/GND pairs distributed across package for low-inductance decoupling and signal integrity. |
| NC (A1, A2, A3, A4, A5, K2, K3, K4, K5) | No internal connection | Reserved pins; must be left unconnected or tied to GND per layout guidelines-no electrical function. |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Output Control (DOC) | Reduces simultaneous switching noise by dynamically increasing output impedance after initial strong drive phase-no speed penalty. |
| Overvoltage-Tolerant I/O | Withstands −0.5 V to 4.6 V on all inputs/outputs, enabling safe interfacing between 1.8 V, 2.5 V, and 3.3 V subsystems. |
| Ioff Partial-Power-Down Support | Disables outputs and blocks current flow when VCC = 0 V, protecting powered-down sections in hot-swap or multi-rail systems. |
| Dual 8-Bit Configurability | Operates as either one 16-bit register or two independent 8-bit registers using separate OE/CLK controls per bank. |
| Widebus™ Architecture | Optimized for high-speed, low-noise bus interface applications with matched propagation delays and tightly controlled timing parameters. |
Applications

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 | No DOC circuit; lower drive (±24 mA static only); 1.65–3.6 V VCC; same pinout but TSSOP-48. | Lacks dynamic noise suppression; suitable where EMI is less critical and board space allows larger TSSOP package. | Choose for cost-sensitive, non-noise-critical designs needing identical logic function without DOC enhancement. |
| SN74AVCH16374DGVR | Includes bus-hold circuitry; same DOC and voltage range; TVSOP-48 package; slightly higher ICC. | Bus-hold eliminates need for external pull-ups on unused inputs; better for floating-bus resilience in industrial I/O. | Prefer when input signal integrity is compromised by long traces or unterminated stubs, and TVSOP footprint is acceptable. |
Compared with SN74LVC16374DGGR and SN74AVCH16374DGVR, the SN74AVC16374ZQLR uniquely combines DOC-based noise reduction, VFBGA-48 compactness, and overvoltage tolerance-making it optimal for high-density, mixed-voltage, noise-sensitive applications where TSSOP/TVSOP footprints are prohibitive.

FAQ
What is the operating voltage range for SN74AVC16374ZQLR?
The SN74AVC16374ZQLR operates from 1.65 V to 3.6 V for full functionality, with data retention supported down to 1.2 V. This wide VCC range enables direct interfacing between 1.8 V, 2.5 V, and 3.3 V logic domains without external level translation, making SN74AVC16374ZQLR ideal for mixed-voltage system design where power domain partitioning is required.
Does SN74AVC16374ZQLR support partial-power-down operation?
Yes, SN74AVC16374ZQLR includes Ioff circuitry that disables outputs and limits current to ±10 µA when VCC = 0 V. This prevents damaging back-current flow from live buses into a powered-down device, supporting safe hot-swap and multi-rail power sequencing-critical for SN74AVC16374ZQLR use in modular industrial and telecom systems.
How does the Dynamic Output Control (DOC) circuit in SN74AVC16374ZQLR reduce noise?
The DOC circuit in SN74AVC16374ZQLR lowers output impedance at signal transition onset for strong drive (±24 mA equivalent), then raises it mid-transition to suppress ringing and ground bounce. This occurs without increasing propagation delay-maintaining 3.3 ns tpd at 3.3 V-so SN74AVC16374ZQLR delivers both speed and signal integrity in high-density PCB layouts.
What is the pin configuration and package type of SN74AVC16374ZQLR?
SN74AVC16374ZQLR uses a VFBGA-48 (GQL) package: 5.5 mm × 5.5 mm, 0.5 mm pitch, bottom-side ball array with 48 terminals. Pin 1 is located in quadrant Q1; NC pins (A1–A5, K2–K5) have no internal connection and must remain unconnected. This compact BGA format supports high I/O density and thermal performance in space-constrained applications.
Can SN74AVC16374ZQLR be used as two independent 8-bit flip-flops?
Yes, SN74AVC16374ZQLR contains two independent 8-bit sections-1Q/1D/1CLK/1OE and 2Q/2D/2CLK/2OE-each with dedicated clock and output-enable controls. This allows concurrent or asynchronous operation of two 8-bit data paths, enabling flexible partitioning in applications like dual-channel sensor aggregation or split-memory addressing-without modifying the SN74AVC16374ZQLR logic function.
