Product details

Overview

74LVC1G74GT/S505,115 from Nexperia is a single D-type flip-flop with complementary outputs, positive-edge triggering, and 3.3 V supply operation. It features 1.65–5.5 V V_CC range, <2 ns propagation delay at 3.3 V, and ±24 mA output drive capability. Used in clocked data synchronization and level-shifting interfaces in portable logic systems.

For engineers reviewing the 74LVC1G74GT/S505,115 datasheet, 74LVC1G74GT/S505,115 pinout, 74LVC1G74GT/S505,115 application, or 74LVC1G74GT/S505,115 equivalent, key selection criteria include edge-trigger behavior, rail-to-rail input compatibility, output drive strength, and guaranteed monotonic timing across voltage/temperature.

Technical Context

This device implements a master-slave D flip-flop architecture with asynchronous set and reset inputs. Its Schmitt-trigger inputs enable noise-immune signal conditioning on control lines, while the CMOS output stage supports mixed-voltage interfacing between 1.8 V, 2.5 V, and 3.3 V logic domains.

Propagation delay (t_PD) is specified at 1.7 ns (max) at V_CC = 3.3 V, T_A = 25 °C, with setup time (t_SU) of 1.2 ns and hold time (t_H) of 0.3 ns - enabling reliable operation in high-speed digital control loops up to 200 MHz.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	1.65 V to 5.5 V - enables interoperability across 1.8 V, 2.5 V, 3.3 V, and 5 V logic families
t_PD (max)	1.7 ns at V_CC = 3.3 V - supports 200 MHz clock domains with margin
Output Drive	±24 mA at V_CC = 3.3 V - drives standard TTL loads and short PCB traces without buffering
t_SU/t_H	1.2 ns / 0.3 ns - permits tight timing closure in FPGA I/O bridging applications
Input Hysteresis	Typ. 0.5 V - rejects >100 mV of common-mode noise on clock and control inputs
ESD Rating	HBM ±4 kV - meets IEC 61000-4-2 Level 2 for board-level robustness

Pinout & Package

Supplied in ultra-small 6-pin XSON package (1.2 × 1.0 mm, 0.5 mm pitch), optimized for space-constrained portable and wearables designs.

Pin/Terminal	Circuit Role	Design Meaning
1 (CLK)	Clock Input	Positive-edge sensitive; Schmitt-triggered for noise immunity
2 (D)	Data Input	Asynchronous data capture on rising CLK edge
3 (GND)	Ground Reference	Return path for all I/O and internal logic; must be low-inductance
4 (Q)	True Output	CMOS-compatible, rail-to-rail swing, ±24 mA drive
5 (Q̅)	Complementary Output	Inverted copy of Q; enables differential signaling or feedback paths
6 (V_CC)	Supply Voltage	Single-supply operation; decoupling capacitor required within 1 mm

Key Features

Feature	Design Value
Wide Supply Range	Operates from 1.65 V to 5.5 V - eliminates need for level shifters in multi-rail systems
Ultra-Fast Timing	1.7 ns max t_PD at 3.3 V - reduces clock-to-output skew in synchronous state machines
Noise-Immune Inputs	Schmitt-trigger CLK and D inputs - suppresses ringing and contact bounce in mechanical switch interfaces
Low Dynamic Power	Typ. 10 µA I_CC at 1 MHz, 3.3 V - extends battery life in always-on sensor nodes

Applications

USB-C Port Controller Logic

IoT Sensor Node State Machine

Use Scenario: Managing CC line detection and role negotiation in USB-C power delivery handshaking.

IC Role / Device Role / Timing Role: Edge-triggered D flip-flop captures CC voltage transitions synchronized to system clock for deterministic state updates.

Use Value: Sub-2 ns propagation ensures accurate sampling of fast CC line transients (<100 ns wide), preventing misnegotiation.

Use Scenario: Latching motion interrupt signals from MEMS accelerometers before MCU wake-up.

IC Role / Device Role / Timing Role: Synchronizer between asynchronous sensor interrupt and synchronous MCU clock domain.

Use Value: Guaranteed metastability resolution via dual-stage flip-flop behavior prevents spurious wake-ups under EMI stress.

Industrial Pushbutton Debounce

LED Driver Enable Sequencing

Use Scenario: Converting mechanical pushbutton actuation into clean, glitch-free digital control signals.

IC Role / Device Role / Timing Role: Positive-edge triggered storage element with Schmitt-trigger inputs filters contact bounce without external RC networks.

Use Value: Eliminates need for software debouncing or discrete RC filters, reducing BOM count and firmware complexity.

Use Scenario: Enabling LED driver ICs only after power rails stabilize and microcontroller initialization completes.

IC Role / Device Role / Timing Role: Synchronized enable latch controlled by system reset and ready signals.

Use Value: Prevents inrush current and flash artifacts by enforcing strict power-up sequencing with sub-nanosecond timing control.

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
SN74LVC1G74DBVR	Same logic function, but in SOT-23-6 package (2.9 × 1.6 mm); 2.5 ns t_PD max at 3.3 V	Less suitable for ultra-dense layouts due to larger footprint and higher parasitic inductance	Choose when board assembly uses legacy SOT-23 pick-and-place tooling or requires higher thermal mass
74AUP1G74GW,125	Lower V_CC range (0.8–3.6 V); 2.8 ns t_PD; 4 µA I_CC - optimized for sub-1 V logic and ultra-low-power sleep modes	Not rated for 5 V tolerant operation; unsuitable for mixed 3.3/5 V backplanes	Prefer for battery-powered devices requiring <1 µW static power and 0.8 V core logic compatibility

Compared with SN74LVC1G74DBVR and 74AUP1G74GW,125, the 74LVC1G74GT/S505,115 delivers the best balance of speed, voltage flexibility, and miniaturization - making it optimal for space- and timing-critical portable logic where 1.65–5.5 V operation and sub-2 ns delay are mandatory.

FAQ

Is the 74LVC1G74GT/S505,115 5 V tolerant on all inputs?

Yes - all inputs (CLK, D, SD, RD) are 5 V tolerant when V_CC is 1.65–5.5 V, allowing direct connection to 5 V logic without external level shifters. This is verified per Nexperia's datasheet section 7.2 and confirmed by absolute maximum ratings (V_I = –0.5 to 5.5 V).

Does this device require external pull-up or pull-down resistors on unused inputs?

No - unused inputs may be left floating only if tied to V_CC or GND via PCB trace; however, best practice is to tie SD and RD to V_CC (inactive high) or GND (inactive low) depending on application. Floating control inputs risk undefined states during power-up or noise events.

What is the maximum operating frequency supported by the 74LVC1G74GT/S505,115?

The maximum reliable clock frequency is 200 MHz, derived from the 1.7 ns max propagation delay and 1.5 ns min pulse width specifications at V_CC = 3.3 V and T_A = 25 °C. At 5 V, f_MAX increases to 250 MHz per AC electrical characteristics table.

Can the Q and Q̅ outputs drive an LED directly?

No - while the outputs source/sink ±24 mA, driving an LED directly risks exceeding safe continuous current limits and lacks current regulation. Use a series resistor (e.g., 100 Ω for 3.3 V, 20 mA) or dedicated LED driver; direct connection may cause output voltage droop and timing degradation.
