Product details
Overview
SN74AUC1G74YZPR from Texas Instruments is a single positive-edge-triggered D-type flip-flop with asynchronous clear (CLR) and preset (PRE), designed for ultra-low-voltage operation from 0.8 V to 2.7 V and optimized for 1.65–1.95 V supply. It delivers ±8-mA output drive at 1.8 V, achieves 1.5 ns max propagation delay (tpd), and features Ioff partial-power-down support. It is used in high-speed level-shifting, clock domain synchronization, and low-power portable logic interfaces.
For engineers reviewing the SN74AUC1G74YZPR datasheet, SN74AUC1G74YZPR pinout, SN74AUC1G74YZPR application, or SN74AUC1G74YZPR equivalent, key selection criteria include sub-1-V operability, 250-MHz max clock frequency at 1.8 V, NanoFree™ DSBGA package footprint, Ioff-enabled power sequencing, and guaranteed 10-μA max ICC across temperature.
Technical Context
This device implements a synchronous edge-triggered storage element with priority-encoded asynchronous control: CLR overrides PRE when both are asserted low. Its internal circuitry supports mixed-mode signal operation - tolerant of 3.6-V I/O while powered from 1.8-V VCC - enabling interoperability between voltage domains without external level shifters.
The flip-flop uses a dual-rail CMOS design with rail-to-rail input thresholds (VIH = 0.65×VCC, VIL = 0.35×VCC) and fast transition-rate handling (Δt/Δv ≤ 20 ns/V). Its NanoFree™ WCSP (YZP) package integrates the silicon die directly as the package, eliminating bond wires and reducing parasitic inductance for improved signal integrity at >200 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Operating Range | 0.8 V to 2.7 V - enables direct integration into sub-1-V and multi-rail systems including battery-powered SoC interfaces. |
| Max Clock Frequency | 250 MHz at 1.8 V - supports high-speed data capture and pipeline staging in portable computing peripherals. |
| tpd (Propagation Delay) | 1.5 ns max at 1.8 V - ensures timing closure in compact PCB layouts with minimal skew between adjacent logic stages. |
| Ioff Support | Active at VCC = 0 V - prevents back-drive current during partial power-down, critical for hot-plug and dynamic power gating. |
| Output Drive | ±8 mA at 1.8 V - drives 15-pF loads with clean edges, eliminating need for external buffers in fanout-limited applications. |
| ICC (Quiescent Current) | 10 μA max - reduces standby power in always-on sensor nodes and wearable controller subsystems. |
| ESD Rating | HBM 2000 V - meets industrial handling requirements without additional protection circuitry on board. |
Pinout & Package
SN74AUC1G74YZPR uses the NanoFree™ DSBGA (YZP) 8-ball wafer-level chip-scale package (1.5 mm × 1.5 mm, 0.5 mm max height), with solder bumps arranged in a 2×4 grid. Pin 1 is located at corner A1 (top-left when orientation mark is viewed).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Ball A1 | CLK | Positive-edge clock input - triggers state update only on rising transition; immune to slow-ramp or noisy clock edges due to Schmitt-trigger-like threshold behavior. |
| Ball A2 | GND | Ground reference - must be connected to system ground plane with low-inductance path to minimize switching noise coupling. |
| Ball B1 | VCC | Supply voltage input - decoupling capacitor (≥0.1 μF) required within 2 mm for stable 250-MHz operation. |
| Ball B2 | Q | True output - complements Q̅; provides registered data synchronized to CLK↑ with 1.5 ns tpd. |
| Ball C1 | Q̅ | Inverted output - electrically complementary to Q; supports differential signaling or enable logic without external inverters. |
| Ball C2 | D | Data input - sampled on CLK↑ if PRE and CLR are high; requires 0.5 ns setup time at 1.8 V for reliable capture. |
| Ball D1 | PRE | Asynchronous preset - forces Q = H, Q̅ = L when low; overridden by CLR if both active simultaneously. |
| Ball D2 | CLR | Asynchronous clear - forces Q = L, Q̅ = H when low; highest-priority control input per functional table. |
Key Features
| Feature | Design Value |
|---|---|
| NanoFree™ WCSP packaging | Die-as-package construction eliminates wirebond inductance, reduces footprint to 1.5 mm × 1.5 mm, and improves thermal resistance (θJA = 102°C/W). |
| Ioff partial-power-down | Outputs enter high-impedance state when VCC = 0 V, preventing back-current flow in multi-rail systems during power sequencing. |
| Mixed-mode I/O tolerance | 3.6-V tolerant inputs/outputs allow direct connection to higher-voltage logic (e.g., 3.3-V microcontrollers) without level translators. |
| Sub-1-V operability | Functional down to 0.8 V VCC - supports emerging ultra-low-power architectures such as near-threshold computing blocks. |
| Latch-up immunity | Exceeds 100 mA per JESD 78 Class II - eliminates need for external current-limiting resistors in harsh ESD environments. |
Applications
| High-Speed Level Translation | Low-Power Clock Domain Crossing |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G74YZPR | Higher VCC min (1.65 V), lower drive (±24 mA at 3.3 V), no sub-1-V operation, 3.6-V I/O tolerant. | Suitable for 3.3-V systems requiring higher noise margin but not ultra-low-voltage operation. | Select when interfacing legacy 3.3-V logic and full 1.65–5.5-V range is needed over sub-1-V capability. |
| NC7SZ74P5X | Smaller SC70-5 package (5-pin), no PRE/CLR, single D/Q pair, 1.65–5.5-V operation, 3.5 ns tpd at 3.3 V. | Lacks asynchronous controls; limited to basic edge-triggered storage without reset/preset functionality. | Choose only when board space is critical and asynchronous control is unnecessary - not a functional replacement. |
Compared with SN74LVC1G74YZPR and NC7SZ74P5X, SN74AUC1G74YZPR uniquely supports true sub-1-V operation, delivers best-in-class 1.5 ns tpd at 1.8 V, and retains full asynchronous PRE/CLR functionality in the smallest NanoFree™ footprint - making it optimal for next-generation ultra-low-power, high-frequency digital interfaces.

FAQ
What is the minimum supply voltage at which SN74AUC1G74YZPR guarantees functional operation?
SN74AUC1G74YZPR is fully specified to operate down to 0.8 V VCC across the full –40°C to +85°C temperature range. At 0.8 V, it maintains valid setup/hold times and output drive capability, enabling use in near-threshold computing and ultra-low-power battery systems where other logic families fail.
Does SN74AUC1G74YZPR support hot insertion or partial power-down sequences?
Yes, SN74AUC1G74YZPR includes Ioff circuitry that disables all outputs when VCC = 0 V, preventing damaging back-current flow through the device during hot-swap or staggered power-up/down events - a requirement for robust industrial and telecom backplane designs.
Can SN74AUC1G74YZPR safely interface between 1.8-V and 3.3-V logic domains?
Yes, SN74AUC1G74YZPR has 3.6-V tolerant inputs and outputs, allowing direct connection to 3.3-V drivers and receivers while powered from 1.8 V. No external level shifters are needed, simplifying interconnect and preserving signal integrity up to 250 MHz.
What is the significance of the NanoFree™ YZP package used in SN74AUC1G74YZPR?
The NanoFree™ YZP package is a 1.5 mm × 1.5 mm DSBGA where the silicon die itself forms the package structure. This eliminates bond wires, reduces parasitic inductance by >50%, lowers θJA to 102°C/W, and enables placement in tight spaces - critical for modern wearables and miniaturized modules.
How does the priority logic between PRE and CLR work in SN74AUC1G74YZPR?
In SN74AUC1G74YZPR, CLR has higher priority than PRE: when both are low, the output is forced to Q = L, Q̅ = H regardless of PRE state. This priority is hardwired in silicon and ensures predictable reset behavior in safety-critical control paths without software arbitration.
