Product details
Overview
SN74AUC1G80YZPR from Texas Instruments is a single positive-edge-triggered D-type flip-flop in a 5-pin NanoFree™ (DSBGA) package, optimized for 1.65–1.95 V operation with 1.9 ns max propagation delay at 1.8 V, ±8 mA output drive, and Ioff support for partial-power-down mode - used in high-speed level-shifting and clock-domain synchronization in portable low-voltage logic systems.
For engineers reviewing the SN74AUC1G80YZPR datasheet, SN74AUC1G80YZPR pinout, SN74AUC1G80YZPR application, or SN74AUC1G80YZPR equivalent, key selection criteria include sub-2 ns timing at 1.8 V, 0.8–2.7 V operational range, Ioff-enabled power sequencing, latch-up immunity (>100 mA), and Pb-free WCSP packaging for ultra-compact board space.
Technical Context
This device implements a synchronous edge-triggered storage element with data capture on the rising edge of CLK, independent of input slew rate. Its internal circuitry ensures robust setup/hold timing (0.5 ns tsu / 0.1 ns th at 1.8 V) and rail-to-rail output swing (VOL ≤ 0.45 V, VOH ≥ VCC – 0.1 V at 1.65 V).
Designed for mixed-mode signal environments, it features 3.6-V I/O tolerance, JESD 78 Class II latch-up immunity, and ESD protection exceeding 2000-V HBM - enabling safe interfacing between 1.8-V core logic and higher-voltage peripherals without external level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 2.7 V - supports battery-powered systems down to single-cell Li-ion (2.7 V) or dual-cell NiMH (1.6 V), with guaranteed operation at 1.65–1.95 V. |
| tpd (max) | 1.9 ns at 1.8 V - enables >250 MHz clock domain bridging in FPGA/CPU interface logic with minimal timing margin impact. |
| Ioff Support | Active at VCC = 0 V - prevents back-drive current during power sequencing, eliminating need for external isolation switches in multi-rail systems. |
| Output Drive | ±8 mA at 1.8 V - sufficient to drive 15 pF loads across PCB traces or multiple CMOS inputs without buffering. |
| ICC (max) | 10 µA - reduces quiescent power in always-on subsystems such as real-time clocks or wake-up controllers. |
| ESD Rating | 2000-V HBM - meets industrial handling requirements without additional board-level protection circuitry. |
| Package | YZP (NanoFree™ DSBGA, 0.23-mm bump, 1.2 × 0.8 mm) - provides smallest footprint among 5-pin logic flip-flops for space-constrained wearables and IoT sensors. |
Pinout & Package
NanoFree™ DSBGA (YZP) package: 5-ball array, 0.4-mm pitch, bottom-side solder bumps, pin 1 identified by non-Pb bump (• = Pb-free). Dimensions: 1.2 mm × 0.8 mm × 0.23 mm height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (D) | Data input | Asynchronous data input referenced to VCC; accepts 0.35×VCC low / 0.65×VCC high thresholds for 1.1–1.95 V operation. |
| 2 (CLK) | Clock input | Positive-edge-sensitive trigger; switching threshold fixed near VCC/2, insensitive to input slew rate per design specification. |
| 3 (GND) | Ground reference | Primary return path for all I/O and supply currents; must be low-impedance to maintain noise margin and timing integrity. |
| 4 (Q) | True output | Non-inverted registered output; drives full rail swing (0 V to VCC) with <0.45 V VOL and >VCC–0.1 V VOH under load. |
| 5 (VCC) | Supply voltage | Core logic supply; powers internal latch and output buffers; supports Ioff when pulled to 0 V while other rails remain active. |

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 |
|---|---|---|---|
| SN74AUC1G74YZPR | Dual D-type flip-flop in same YZP package; double the logic density but shares VCC/GND pins - increases supply current to 20 µA max. | Requires simultaneous registration of two independent signals; not suitable when only single-bit retiming is needed. | Select SN74AUC1G74YZPR only if dual-channel functionality justifies added layout complexity and 2× ICC. |
| 74LVC1G74GW,125 | Single DFF in SC-70 (SOT-353) package; 1.65–5.5 V range, 3.5 ns tpd at 3.3 V, no Ioff support. | Lacks Ioff and sub-2 V operation - unsuitable for partial-power-down or battery-critical designs below 1.65 V. | Choose 74LVC1G74GW,125 only for 3.3-V-only systems where cost-per-unit outweighs size and power advantages of YZP. |
Compared with SN74AUC1G74YZPR and 74LVC1G74GW,125, the SN74AUC1G80YZPR uniquely combines ultra-small WCSP footprint, sub-2 ns speed at 1.8 V, and Ioff-enabled power sequencing - making it the sole option for space- and power-constrained 1.8-V retiming where rail independence is mandatory.

FAQ
What is the minimum operating voltage for the SN74AUC1G80YZPR?
The SN74AUC1G80YZPR operates down to 0.8 V, with guaranteed functionality across the full recommended range of 0.8 V to 2.7 V. Its optimal performance window is 1.65 V to 1.95 V, where parameters like tpd, setup time, and output drive are fully characterized - critical for battery-powered devices experiencing voltage sag during peak current draw.
Does the SN74AUC1G80YZPR support partial-power-down mode?
Yes, the SN74AUC1G80YZPR includes Ioff circuitry that disables outputs when VCC = 0 V, preventing damaging back-current flow from live I/O lines into a powered-down section. This feature is explicitly verified per JESD 78 Class II latch-up testing and allows safe integration in multi-rail systems without external isolation components.
What is the maximum clock frequency supported by the SN74AUC1G80YZPR at 1.8 V?
At VCC = 1.8 V, the SN74AUC1G80YZPR supports a maximum clock frequency (fmax) of 250 MHz under CL = 15 pF loading conditions. This is derived directly from its 1.9 ns max tpd and validated timing specifications - enabling use in high-speed control loops and data sampling paths within 1.8-V domains.
Is the SN74AUC1G80YZPR pin-compatible with other packages in the same family?
No - the SN74AUC1G80YZPR uses the YZP NanoFree™ DSBGA package (1.2 mm × 0.8 mm), which has a different ball map and mounting geometry than the DBV (SOT-23) or DCK (SC-70) variants. While functionally identical, mechanical replacement requires PCB redesign due to distinct land patterns, stencil apertures, and reflow profiles.
How does the SN74AUC1G80YZPR handle input signals exceeding VCC?
The SN74AUC1G80YZPR features 3.6-V tolerant I/Os, meaning inputs (D, CLK) and outputs (Q) can safely accept voltages up to 3.6 V regardless of VCC level - verified per absolute maximum ratings and JESD 76 compliance. This enables direct interfacing with 3.3-V peripherals in 1.8-V systems without level-shifting circuitry.
