Product details
Overview
SN74LVC1G80YZAR from Texas Instruments is a single positive-edge-triggered D-type flip-flop designed for 1.65V to 5.5V VCC operation, delivering 4.2ns max propagation delay at 3.3V, ±24mA output drive, and Ioff-enabled partial-power-down protection. It functions as a synchronous data latch in clock-domain interfacing, frequency division, and signal synchronization circuits.
For engineers reviewing the SN74LVC1G80YZAR datasheet, SN74LVC1G80YZAR pinout, SN74LVC1G80YZAR application, or SN74LVC1G80YZAR equivalent, key selection criteria include its DSBGA-5 NanoFree™ package (1.41mm × 0.91mm), 125°C max operating temperature (DBV/DCK) vs. 85°C (YZP), edge-triggered timing behavior, and over-voltage tolerant inputs up to 5.5V.
Technical Context
The SN74LVC1G80YZAR implements a CMOS-based positive-edge-triggered D flip-flop with transmission-gate logic architecture. Its clock input triggers on voltage threshold crossing-not edge slew rate-enabling robust timing across varying clock rise times. The device lacks asynchronous preset/clear, so Q output state is undefined at power-up.
It features standard CMOS inputs with 3.5pF typical input capacitance and balanced push-pull outputs capable of sourcing/sinking ±24mA at 3.3V. Ioff circuitry forces all I/O into high-impedance when VCC = 0V, preventing back-drive current and enabling hot-insertion in multi-rail systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - supports mixed-voltage system interfacing and direct connection to 1.8V/2.5V/3.3V/5V logic rails |
| tpd (max) | 4.2ns at 3.3V, CL = 15pF - enables reliable operation in ≥238MHz clock domains with margin |
| IOH/IOL | ±24mA at 3.3V - drives moderate capacitive loads or multiple 74LVC inputs without buffering |
| Ioff | ±10µA max - ensures safe isolation during partial power-down, critical for FPGA I/O bank sequencing |
| Input Voltage Tolerance | Up to 5.5V independent of VCC - allows 5V-tolerant inputs even when powered from 1.8V |
| ESD Rating (HBM) | ±2000V - meets industrial-grade ESD immunity requirements per ANSI/ESDA/JEDEC JS-001 |
| Operating Temperature | –40°C to +85°C - qualified for consumer, telecom, and enterprise equipment environments |
Pinout & Package
SN74LVC1G80YZAR uses the YZP package: a 5-pin DSBGA (Die Size Ball Grid Array) with 0.4mm pitch, footprint 1.41mm × 0.91mm, and bottom-side ball layout optimized for ultra-compact PCB space and thermal performance (RθJA = 136.9°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - D | Data input | CMOS-compatible input accepting 0V to 5.5V; requires setup time (1.3ns min at 3.3V) before CLK↑ |
| 2 - CLK | Clock input | Positive-edge-triggered; threshold-based triggering decouples timing from clock slew rate |
| 3 - GND | Ground reference | Return path for all internal logic and I/O; must be low-impedance for noise immunity |
| 4 - Q | Non-inverting output | Push-pull CMOS output; sources/sinks ±24mA at 3.3V; no internal pull-up/down |
| 5 - VCC | Power supply | Single supply rail (1.65–5.5V); powers internal logic and output drivers; bypass with 0.1µF capacitor |
Key Features
| Feature | Design Value |
|---|---|
| NanoFree™ DSBGA packaging | Dies-as-package construction eliminates leadframe and mold compound, reducing size to 1.41mm × 0.91mm and improving thermal resistance (RθJC(bot) = 32.6°C/W) |
| Ioff partial-power-down | Disables outputs and isolates I/O pins when VCC = 0V, preventing back-current damage during board hot-swap or power sequencing |
| Over-voltage tolerant inputs | Accepts input signals up to 5.5V regardless of VCC level - simplifies level-shifting in mixed-supply systems |
| Low ICC consumption | 10µA max quiescent current - suitable for battery-backed or always-on monitoring circuits |
| High-speed timing | 4.2ns tpd at 3.3V enables use in clock distribution, sampling, and real-time control loops with sub-5ns timing budgets |
Applications

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 | Dual D-type flip-flop in same YZP package; includes asynchronous clear (CLR) and preset (PRE) pins | Required where deterministic power-up state or asynchronous reset is needed; occupies same PCB area but doubles channel count | Select SN74LVC1G74YZPR only if dual-channel operation or guaranteed initial state is mandatory; otherwise SN74LVC1G80YZAR offers lower cost and simpler routing |
| 74LVC1G80GW,125 | NXP variant in SC-70-5 package (2.00mm × 1.25mm); identical electrical specs but different thermal metrics (RθJA = 371°C/W) | Suitable for legacy SC-70 layouts; higher thermal resistance limits sustained high-speed operation in dense boards | Choose 74LVC1G80GW,125 only for SC-70 compatibility; SN74LVC1G80YZAR provides superior thermal performance and smaller footprint |
Compared with SN74LVC1G74YZPR and 74LVC1G80GW,125, the SN74LVC1G80YZAR delivers the smallest form factor (DSBGA-5), lowest thermal resistance, and optimal balance of speed (4.2ns tpd) and power (10µA ICC) for space-constrained, high-density digital systems requiring single-channel edge-triggered storage.

FAQ
What is the maximum operating temperature for SN74LVC1G80YZAR?
The SN74LVC1G80YZAR is rated for operation from –40°C to +85°C. This differs from the DBV and DCK variants (–40°C to +125°C) due to package-specific thermal limitations of the YZP DSBGA construction. Always verify ambient and junction temperature margins using RθJA = 136.9°C/W in thermal design calculations for the SN74LVC1G80YZAR.
Does SN74LVC1G80YZAR support asynchronous reset or preset functionality?
No, the SN74LVC1G80YZAR does not include asynchronous reset (CLR) or preset (PRE) inputs. It is a basic positive-edge-triggered D-type flip-flop with only CLK, D, Q, VCC, and GND terminals. Its output state is undefined at power-up, requiring external initialization if deterministic startup is needed - a key distinction from variants like SN74LVC1G74YZPR.
Can SN74LVC1G80YZAR be used with a 5V input signal while powered from 1.8V?
Yes, the SN74LVC1G80YZAR supports over-voltage tolerant inputs up to 5.5V regardless of VCC level. When powered from 1.8V, the D and CLK inputs safely accept 5V logic signals without level shifters - a verified feature per Section 5.3 of the datasheet, enabled by integrated input clamp diodes and current-limited I/O structure.
What is the purpose of the Ioff feature in SN74LVC1G80YZAR?
The Ioff feature in SN74LVC1G80YZAR disables all outputs and places inputs in high-impedance when VCC = 0V, preventing back-drive current from other powered rails into the unpowered device. This protects the SN74LVC1G80YZAR during partial power-down sequences and enables safe hot-plug operation in modular systems - confirmed by Ioff ≤ ±10µA in Section 5.5.
Is SN74LVC1G80YZAR pin-compatible with other SN74LVC1G80 package variants?
No, SN74LVC1G80YZAR is not pin-compatible with SN74LVC1G80DBV (SOT-23) or SN74LVC1G80DCK (SC-70). While all share identical logic function and 5-terminal assignment (D, CLK, GND, Q, VCC), the YZP DSBGA uses bottom-side ball mapping, whereas DBV and DCK use top-side leads with different physical pin orders. PCB layout must be redesigned for each package.
