Product details
Overview
SN74LVC16374AGQLR 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 two independent 8-bit registers or one unified 16-bit latch, supports 5.5-V tolerant inputs, delivers ±24 mA output drive at 3.3 V, and operates up to 150 MHz - enabling high-speed bus buffering in server memory interfaces.
For engineers reviewing the SN74LVC16374AGQLR datasheet, SN74LVC16374AGQLR pinout, SN74LVC16374AGQLR application, or SN74LVC16374AGQLR equivalent, key selection criteria include Ioff-enabled live insertion support, mixed-voltage (3.3-V/5-V) signal translation capability, 3-state output timing (ten = 4.5 ns max at 3.3 V), and thermal performance (RθJA = 64.3°C/W in DGG package).
Technical Context
This device implements dual 8-bit positive-edge-triggered D flip-flops with independent clock (1CLK/2CLK) and output-enable (1OE/2OE) controls. Each channel latches data on the rising edge of its dedicated clock and places its eight Q outputs into high-impedance when OE is high.
It features Ioff circuitry that disables outputs during partial power-down, supports down-translation from 5-V inputs to 3.3-V logic levels, and maintains latch integrity while outputs are tri-stated - allowing concurrent data retention and bus release without affecting internal state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 3.6 V - enables single-supply operation across low-voltage embedded and industrial systems |
| Max Clock Frequency | 150 MHz - supports high-throughput data latching in DDR memory buffers and PCIe sideband control paths |
| I/O Voltage Tolerance | Inputs rated to 5.5 V - allows direct interfacing with legacy 5-V logic without level shifters |
| Output Drive | ±24 mA at VCC = 3.3 V - drives 10+ LVC loads or terminates stubs in point-to-point bus topologies |
| tpd (CLK→Q) | 1.5 ns to 4.5 ns - ensures sub-5-ns propagation for timing-critical register staging in FPGA I/O expansion |
| Ioff | ±10 μA at VCC = 0 V - prevents back-drive current during hot-swap or power sequencing in modular backplanes |
| ESD Rating | 2000-V HBM - meets industrial-grade robustness requirements for field-deployable equipment |
Pinout & Package
GQL package: 56-ball ZQFN (3.5 mm × 4.5 mm, 0.5-mm pitch), thermally enhanced with exposed thermal pad. Pin 1 located at quadrant Q1 per JEDEC standard tape orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE | Active-low output enable | Independent control of each 8-bit output bank; high = 3-state, low = functional drive |
| 1CLK, 2CLK | Positive-edge clock input | Triggers simultaneous latching of all eight D inputs in respective bank on rising edge |
| 1D1–1D8, 2D1–2D8 | Data inputs | Asynchronous inputs sampled only at clock edge; 5.5-V tolerant, no external clamping required |
| 1Q1–1Q8, 2Q1–2Q8 | Tri-state outputs | CMOS-compatible outputs with rail-to-rail swing; high-impedance leakage <10 μA |
| VCC (Pins 3,4,18,31,42) | Power supply | Five distributed VCC pins reduce switching noise and improve PSRR in high-speed operation |
| GND (Pins 4,10,15,21,28,34,39,45) | Ground reference | Eight GND pins provide low-inductance return paths for 16 outputs and internal logic |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.65–3.6 V) | Enables drop-in use across 1.8-V, 2.5-V, and 3.3-V system domains without redesign |
| 5.5-V tolerant inputs | Eliminates need for external voltage translators when interfacing with 5-V microcontrollers or legacy peripherals |
| Ioff protection | Permits safe live insertion into powered backplanes by blocking reverse current flow during VCC ramp-up/down |
| Low ground bounce (VOLP < 0.8 V) | Reduces digital noise coupling into analog sections and improves signal integrity in mixed-signal PCBs |
| High noise immunity (VOIH/VIL margins) | Guarantees >0.7-V noise margin at 3.3-V operation, supporting reliable operation in electrically noisy industrial environments |

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 |
|---|---|---|---|
| SN74LVC16373ADGGR | Latch (transparent) vs. flip-flop (edge-triggered); no clock input, gated by OE only | Suitable for static data hold but not synchronous sampling; lacks timing control for burst protocols | Select when asynchronous data capture suffices and clock tree simplification is prioritized over timing precision |
| 74ALVC16374PW | Higher VCC max (3.6 V same), but lower drive (±24 mA vs. ±32 mA), no Ioff support | Not suitable for live-insertion systems; requires external power sequencing controls | Choose only for cost-sensitive consumer designs where hot-swap capability is unnecessary |
Compared with SN74LVC16374AGQLR, SN74LVC16373ADGGR trades edge-triggered synchronization for simpler gating logic, while 74ALVC16374PW sacrifices Ioff and thermal efficiency for legacy footprint compatibility - making SN74LVC16374AGQLR optimal for thermally constrained, hot-pluggable infrastructure applications.

FAQ
What is the maximum operating temperature for SN74LVC16374AGQLR?
The SN74LVC16374AGQLR is rated for operation from –40°C to +125°C ambient temperature, validated per JEDEC JESD78 reliability testing. This full industrial temperature range ensures stable performance in server chassis, outdoor base stations, and under-hood automotive environments where thermal cycling exceeds 100°C.
Does SN74LVC16374AGQLR support live insertion in powered backplanes?
Yes, SN74LVC16374AGQLR incorporates Ioff circuitry that disables outputs and limits reverse current to ±10 μA when VCC = 0 V, enabling safe hot-plug operation in modular telecom and industrial backplanes without risk of bus contention or damage to upstream drivers.
Can SN74LVC16374AGQLR interface directly with 5-V logic inputs?
Yes, SN74LVC16374AGQLR accepts input voltages up to 5.5 V regardless of VCC level, allowing direct connection to 5-V microcontrollers, FPGAs, or legacy peripherals without external level shifters - a key feature confirmed in Section 9.3 of the SCAS728B datasheet.
What is the recommended bypass capacitor configuration for SN74LVC16374AGQLR?
TI recommends placing a 0.1-μF ceramic capacitor between each VCC pin and nearest GND pin, with additional 1-μF bulk capacitance near the device. The SN74LVC16374AGQLR has five VCC pins (3,4,18,31,42), so five localized 0.1-μF caps are required to suppress simultaneous switching noise and maintain <100-mV supply ripple.
How does the dual OE architecture of SN74LVC16374AGQLR improve system design?
The independent 1OE and 2OE inputs allow selective tri-stating of either 8-bit bank - enabling time-multiplexed bus sharing, dynamic partitioning of memory-mapped I/O, and fault-isolation in redundant control paths. This eliminates need for external multiplexers or additional logic gates in complex embedded systems.
