Product details
Overview
74LVC374APW from Nexperia is an octal positive-edge-triggered D-type flip-flop with 3-state outputs, designed for data latching and bus isolation in mixed-voltage digital systems. It operates from 1.2 V to 3.6 V supply, tolerates 5.5 V inputs/outputs, features IOFF partial power-down protection, and supports -40 °C to +125 °C industrial temperature range - used in FPGA I/O bridging, microcontroller peripheral expansion, and level-translating data buses.
For engineers reviewing the 74LVC374APW datasheet, 74LVC374APW pinout, 74LVC374APW application, or 74LVC374APW equivalent, key selection criteria include its 5.5 V overvoltage-tolerant inputs, 3-state output enable timing (ten ≤ 9.5 ns), propagation delay (tpd ≤ 9.0 ns at 3.3 V), IOFF leakage (< ±10 μA at VCC = 0 V), and TSSOP20 package compatibility with high-density PCB layouts.
Technical Context
This device implements eight independent edge-triggered D-flip-flops sharing a common clock (CP) and active-low output enable (OE). Each flip-flop captures Dn input state on the LOW-to-HIGH CP transition, while OE independently controls output impedance without affecting internal register state.
Schmitt-trigger inputs tolerate slow signal edges; IOFF circuitry disables outputs during power-down to prevent backflow current; and JEDEC-compliant voltage operation (JESD8-7A/5A/C) ensures interoperability across 1.65–3.6 V logic families. The architecture enables simultaneous data capture and controlled bus release in synchronous digital interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.2 V to 3.6 V - supports low-power 1.8 V and standard 3.3 V systems without level shifters |
| Input Voltage Tolerance | Up to 5.5 V - enables direct connection to 5 V legacy peripherals or mixed-voltage buses |
| Propagation Delay (tpd) | ≤ 9.0 ns at VCC = 3.3 V - ensures timing compliance in 100+ MHz synchronous data paths |
| Set-up/Hold Time (tsu/th) | 2.0 ns / 1.5 ns at VCC = 3.3 V - defines minimum data stability window before/after clock edge |
| IOFF Leakage Current | < ±10 μA at VCC = 0 V - prevents damaging backflow during partial power-down sequences |
| Operating Temperature | -40 °C to +125 °C - qualified for extended industrial and under-hood embedded applications |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to drive 50 pF loads with < 1.5 ns skew between outputs |
Pinout & Package
TSSOP20 plastic thin shrink small outline package (SOT360-1), 20-pin, 4.4 mm body width, 0.65 mm pitch - optimized for automated assembly and thermal performance in space-constrained designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Active-low output enable | Drives all Qn outputs to high-impedance when HIGH; no effect on internal flip-flop states |
| 2–5, 6–9, 12–15, 16–19 (Q0–Q7) | 3-state flip-flop outputs | Octal registered outputs with controlled drive and bus-release timing (ten/tdis ≤ 9.5 ns) |
| 3–4, 7–8, 13–14, 17–18 (D0–D7) | Data inputs | Individual D-inputs sampled synchronously on LOW-to-HIGH CP edge with Schmitt-trigger noise immunity |
| 10 (GND) | Ground reference | 0 V return path for all internal logic and I/O circuits |
| 11 (CP) | Clock input | Positive-edge-triggered control signal; determines exact sampling instant for all D inputs |
| 20 (VCC) | Supply voltage | Primary power rail (1.2–3.6 V); powers core logic and I/O buffers |
Key Features
| Feature | Design Value |
|---|---|
| 5.5 V tolerant inputs/outputs | Enables direct interfacing with 5 V devices without external level translators in mixed-supply systems |
| IOFF partial power-down protection | Prevents destructive backflow current when VCC = 0 V and I/O pins are driven externally |
| Schmitt-trigger input thresholds | Rejects slow-rising/falling signals and improves noise immunity on noisy PCB traces or cables |
| Independent register and 3-state control | Allows data capture (via CP) and bus release (via OE) to occur asynchronously - critical for glitch-free bus arbitration |
| JEDEC-compliant voltage ranges | Validated operation per JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C (2.7–3.6 V) |
Applications
| Industrial PLC I/O Expansion | FPGA-to-Microcontroller Interface |

Use Scenario: Isolating and latching sensor data from 24 V field inputs via level-shifted digital signals into a 3.3 V FPGA fabric. IC Role / Device Role / Timing Role: Octal D-flip-flop capturing parallel sensor status bits on synchronized clock edge; 3-state outputs decoupled during FPGA reconfiguration. Use Value: Eliminates need for discrete level shifters and provides deterministic setup/hold timing (tsu = 2.0 ns) for reliable capture at >50 MHz update rates. |
Use Scenario: Buffering and synchronizing command/status registers between a 1.8 V microcontroller and 3.3 V peripheral ASIC. IC Role / Device Role / Timing Role: Bidirectional data latch enabling safe handshaking; OE-controlled bus release prevents contention during MCU sleep mode transitions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC374APWR (TI) | Identical pinout and electrical specs; slightly higher ICC (max 40 μA vs 10 μA) at VCC = 3.6 V | Same industrial temperature range (-40 °C to +125 °C); identical TSSOP20 package | Preferred where TI's long-term supply assurance or existing qualification in automotive Tier-1 BOMs is required |
| 74ALVC374PW,118 (Nexperia) | Higher speed (tpd ≤ 3.6 ns at 3.3 V); narrower VCC range (2.3–3.6 V); same IOFF and 5.5 V tolerance | Not rated for 1.2–1.95 V operation; unsuitable for ultra-low-voltage battery-powered systems | Select when maximum timing margin is critical and supply is stable ≥2.3 V - e.g., high-speed test equipment |
Compared with SN74LVC374APWR, the 74LVC374APW offers lower static current for battery-sensitive designs; versus 74ALVC374PW, it trades speed for broader voltage flexibility - making it optimal for mixed-supply industrial controllers requiring robustness over raw speed.

FAQ
Does the 74LVC374APW support hot insertion?
Yes - its IOFF circuitry actively disables outputs when VCC = 0 V, preventing backflow current even if I/O pins are driven externally during live insertion. This feature is validated per JEDEC JESD78 and enables safe hot-plug operation in modular backplane systems.
Can OE be toggled asynchronously while CP is active?
Yes - OE operates independently of the clock and flip-flop state. Outputs transition to high-impedance within ten ≤ 9.5 ns (at VCC = 3.3 V) regardless of CP activity, enabling dynamic bus arbitration without disrupting internal register contents.
What is the maximum clock frequency supported at 1.8 V supply?
At VCC = 1.8 V, the maximum guaranteed clock frequency is 100 MHz over the full -40 °C to +125 °C range. This is derived from tW (minimum pulse width) of 5.0 ns and fmax specifications in Table 7 of the datasheet Rev. 6.
Is the TSSOP20 package RoHS and REACH compliant?
Yes - the 74LVC374APW in SOT360-1 (TSSOP20) package meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free terminations and halogen-free molding compound, as confirmed in Nexperia's official compliance documentation.
