Product details
Overview
74LVT74D,118 from NXP Semiconductors (formerly Philips) is a 3.3 V dual positive-edge-triggered D-type flip-flop with asynchronous active-low set (SD) and reset (RD), true/complementary outputs per channel, 14-pin SO package, and propagation delay of 3.1 ns (tPLH) at VCC = 3.3 V. It operates across –40°C to +85°C and supports high-speed clocking up to 345 MHz at VCC = 2.7 V in industrial logic systems.
For engineers reviewing the 74LVT74D,118 datasheet, 74LVT74D,118 pinout, 74LVT74D,118 application, or 74LVT74D,118 equivalent, key selection criteria include asynchronous control timing, low-voltage 3.3 V operation, dual-channel edge-triggered storage, and compatibility with LVT logic families in high-density PCB designs.
Technical Context
The 74LVT74D,118 implements two independent D-type flip-flops sharing no internal coupling-each with dedicated clock (CPn), data (Dn), set (SDn), reset (RDn), Qn, and Qn terminals. Clock triggering occurs on the low-to-high transition, with setup time as low as 0.4 ns and hold time down to –0.6 ns at VCC = 2.7 V.
All inputs accept 5.5 V tolerant logic levels; outputs drive ±32 mA (IOL/IOH) under recommended conditions. The device uses bipolar transistor–transistor logic (BTL) architecture optimized for low skew and high noise immunity in mixed-voltage 3.3 V systems interfacing with 5 V peripherals via level-shifting buffers.
Key Specifications

|---|---|
| Supply Voltage | 2.7 V to 3.6 V - Enables stable operation in modern 3.3 V digital rails without external regulation |
| Max Clock Frequency | 345 MHz at VCC = 2.7 V - Supports high-throughput data latching in fast synchronous logic paths |
| Propagation Delay (tPLH) | 3.1 ns typical at VCC = 3.3 V, CL = 50 pF - Ensures tight timing margins in pipeline stages |
| Input Capacitance | 3 pF - Minimizes loading on preceding drivers and preserves signal integrity in fanout-critical nets |
| Output Drive Strength | ±32 mA - Sufficient to directly drive multiple LVT/LVC inputs or small capacitive loads without buffering |

Pinout & Package
74LVT74D,118 is housed in a 14-lead plastic small outline (SO) package per SOT108-1, 3.9 mm body width, surface-mount compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 13 | RD0, RD1 | Asynchronous reset inputs (active LOW) - Force Qn = LOW independently of clock; critical for power-up initialization |
| 2, 12 | D0, D1 | Data inputs - Sampled on rising clock edge; must meet 0.4 ns minimum hold time at VCC = 2.7 V |
| 3, 11 | CP0, CP1 | Positive-edge clock inputs - Trigger storage only on low-to-high transition; voltage-level sensitive, not edge-rate dependent |
| 4, 10 | SD0, SD1 | Asynchronous set inputs (active LOW) - Force Qn = HIGH regardless of clock or data state |
| 5, 6, 8, 9 | Q0, Q0, Q1, Q1 | True and complementary outputs - Provide simultaneous access to stored bit and its inverse for differential signaling or feedback |
| 7 | GND | Ground reference - Must be connected to system ground plane with low-inductance path to minimize switching noise |
| 14 | VCC | 3.3 V supply input - Requires local 100 nF ceramic decoupling capacitor placed within 5 mm of pin |
Key Features
| Feature | Design Value |
|---|---|
| 5.5 V tolerant inputs | Accepts 0–5.5 V logic signals while powered from 3.3 V - Eliminates need for external level shifters when interfacing with legacy 5 V controllers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC74APW | Lower ICC (0.1 µA typical vs. 0.5 mA), but reduced fMAX (200 MHz at VCC = 3.3 V); same 14-pin TSSOP footprint | Preferred for ultra-low-power portable instrumentation where clock rate ≤150 MHz suffices | Select SN74LVC74APW when static current dominates thermal budget and speed margin allows 30% reduction |
| 74ALVC74MTCX | Higher noise immunity (VIL = 0.7 V min), identical AC specs, but requires tighter VCC regulation (3.0–3.6 V only) | Better suited for electrically noisy factory-floor PLC backplanes with marginal power rail stability | Choose 74ALVC74MTCX when EMI susceptibility is primary concern and supply regulation can be maintained within ±3% |
Compared with SN74LVC74APW and 74ALVC74MTCX, the 74LVT74D,118 delivers superior high-frequency performance (345 MHz) and higher drive strength (±32 mA), making it optimal for timing-critical industrial control and test equipment where signal fidelity and edge rate dominate over quiescent power.

FAQ
What is the maximum clock frequency supported by the 74LVT74D,118?
The 74LVT74D,118 supports a maximum clock frequency of 345 MHz when operated at VCC = 2.7 V across the full industrial temperature range (–40°C to +85°C). At nominal 3.3 V supply, typical operation exceeds 150 MHz. This high-speed capability makes the 74LVT74D,118 suitable for demanding applications such as high-throughput data acquisition and real-time digital signal processing where precise edge-aligned latching is required.
Does the 74LVT74D,118 support 5 V logic inputs while powered from 3.3 V?
Yes, the 74LVT74D,118 features 5.5 V tolerant inputs, allowing it to accept logic-high signals up to 5.5 V while operating from a 3.3 V supply. This eliminates the need for external level-shifting circuitry when interfacing with legacy 5 V microcontrollers or peripheral devices, simplifying board design and improving signal integrity in mixed-voltage systems containing the 74LVT74D,118.
What are the absolute maximum ratings for supply voltage and output current on the 74LVT74D,118?
The 74LVT74D,118 has an absolute maximum DC supply voltage (VCC) rating of –0.5 V to +4.6 V and can sink up to 64 mA or source up to –32 mA per output. These ratings define electrical stress limits-not operational conditions-and exceeding them may cause permanent damage. For reliable operation, the 74LVT74D,118 must be used within its recommended 2.7–3.6 V supply range and ±32 mA output current limits.
How does the asynchronous set/reset functionality work on the 74LVT74D,118?
The 74LVT74D,118 provides independent active-low asynchronous set (SDn) and reset (RDn) inputs for each flip-flop channel. When SDn is pulled LOW, Qn immediately goes HIGH regardless of clock or data state; when RDn is LOW, Qn immediately goes LOW. These functions operate independently of the clock and override all synchronous behavior-enabling deterministic initialization, fault recovery, and safe power-up sequencing in systems using the 74LVT74D,118.
Is the 74LVT74D,118 pin-compatible with other 74-series dual D-type flip-flops?
No, the 74LVT74D,118 is not pin-compatible with standard 74LS74 or 74HC74 devices due to differing pin assignments-specifically, its SDn and RDn inputs occupy pins 4/10 and 1/13, unlike the 74HC74's shared preset/clear configuration. Engineers must verify layout compatibility before substituting the 74LVT74D,118 into existing designs originally intended for other 74-series variants.
