Product details
Overview
74ALVC374PW,112 from Nexperia is an octal positive-edge-triggered D-type flip-flop with 3-state outputs, designed for data latching and bus interface in low-voltage digital systems. It operates from 1.65 V to 3.6 V, features IOFF partial power-down protection, Schmitt-trigger inputs for noise immunity, and supports -40 °C to +125 °C industrial temperature range - used in FPGA I/O expansion, microcontroller peripheral buffering, and memory address/data bus isolation.
For engineers reviewing the 74ALVC374PW,112 datasheet, 74ALVC374PW,112 pinout, 74ALVC374PW,112 application, or 74ALVC374PW,112 equivalent, key selection criteria include its 3.6 ns max propagation delay at 3.3 V, 0.8 ns min setup time, IOFF-enabled hot-swap capability, and TSSOP20 package compatibility with high-density PCB layouts.
Technical Context
This device implements eight independent D-type flip-flops synchronized to the rising edge of CP, with asynchronous 3-state control via active-low OE. Each flip-flop samples Dn on LOW-to-HIGH clock transition and holds state until next valid edge - no internal reset or preset logic is present.
All inputs include Schmitt-trigger circuitry enabling robust operation with slow-rising signals, while the IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during partial power-down sequences - critical for mixed-supply system interoperability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.65 V to 3.6 V - enables direct interfacing with 1.8 V, 2.5 V, and 3.3 V logic families without level shifters. |
| Propagation Delay (tpd) | 3.6 ns max at VCC = 3.3 V - ensures sub-4 ns timing margin for 150 MHz system clocks. |
| Set-up Time (tsu) | 0.8 ns min at VCC = 3.3 V - supports high-speed data capture with minimal timing slack. |
| IOFF Leakage | ±80 μA max at VCC = 0 V - prevents destructive back-current during hot-insertion or supply sequencing. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive modules and industrial motor drives. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets JEDEC JS-001/JS-002 Class C3 for robust board-level handling. |
| Output Drive | ±24 mA at VCC = 3.0 V - sufficient to drive 50 pF loads across 10 cm traces without signal integrity degradation. |
Pinout & Package
TSSOP20 package (SOT360-1): 20-pin thin shrink small outline, 4.4 mm body width, 0.65 mm pitch, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Output Enable (active LOW) | Asynchronously places all Q outputs in high-impedance state; does not affect internal flip-flop states. |
| 2 (Q0), 5 (Q1), 6 (Q2), 9 (Q3), 12 (Q4), 15 (Q5), 16 (Q6), 19 (Q7) | 3-state output | Octal buffered outputs supporting bidirectional bus sharing; driven HIGH/LOW or tri-stated per OE. |
| 3 (D0), 4 (D1), 7 (D2), 8 (D3), 13 (D4), 14 (D5), 17 (D6), 18 (D7) | Data input | Individual D inputs sampled synchronously on CP rising edge; Schmitt-triggered for noise rejection. |
| 11 (CP) | Clock input | Positive-edge-triggered master clock; LOW-to-HIGH transition initiates sampling and storage. |
| 10 (GND), 20 (VCC) | Power terminals | Dedicated ground and supply pins minimize switching noise coupling into sensitive clock and data paths. |
Key Features
| Feature | Design Value |
|---|---|
| IOFF Partial Power-down | Outputs disable automatically when VCC = 0 V, eliminating backflow current in mixed-rail systems. |
| Schmitt-trigger Inputs | Input hysteresis ≥ 0.3 V at VCC = 3.3 V - tolerates slow edges up to 10 ns/V slew rate without metastability. |
| Overvoltage-Tolerant Inputs | Accepts 3.6 V signals even at VCC = 1.65 V - enables safe interfacing with higher-voltage peripherals. |
| Latch-up Immunity | Exceeds 250 mA per JESD78 Class II.A - ensures reliability in noisy industrial environments. |
| Wide Temp Range | Specified from -40 °C to +125 °C - validated for extended operation in engine control units and power converters. |
Applications
| Industrial PLC I/O Expansion | FPGA Configuration Bus Interface |
|---|---|
|
Use Scenario: Isolating and latching digital sensor inputs (e.g., limit switches, encoder quadrature signals) before routing to a central controller. IC Role / Device Role / Timing Role: Octal D-flip-flop acting as synchronous input register; CP aligned to system clock domain, OE tied LOW for continuous capture. Use Value: Eliminates metastability risk with 0.8 ns setup time and Schmitt-triggered inputs, ensuring deterministic sampling of noisy field signals. |
Use Scenario: Buffering configuration data between FPGA configuration memory and I/O banks during power-up or reconfiguration. IC Role / Device Role / Timing Role: Bidirectional bus latch providing controlled data staging; OE managed by FPGA to enable/disable data flow during state transitions. Use Value: 3-state outputs prevent bus contention during partial reconfiguration; IOFF protects against backfeed when FPGA VCC ramps independently. |
| Microcontroller Peripheral Multiplexing | Memory Address/Data Bus Isolation |
|
Use Scenario: Sharing limited GPIO pins among multiple peripherals (e.g., SPI flash, UART transceivers, LED drivers) using time-multiplexed control lines. IC Role / Device Role / Timing Role: Output latch holding peripheral enable states; CP driven by MCU timer output, OE controlled by software-selectable bank. Use Value: Enables single MCU port to drive 8 independent enables with precise edge-aligned timing, reducing firmware overhead. |
Use Scenario: Decoupling SRAM or Flash memory data/address buses from processor core during DMA transfers or cache flushes. IC Role / Device Role / Timing Role: Transparent latch isolating memory bus segments; CP synchronized to memory controller strobe, OE asserted during idle cycles. Use Value: Prevents signal reflections and crosstalk during bus turnaround; 3.6 ns tpd ensures <1 ns skew across all 8 bits for parallel access integrity. |
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 part with identical pinout and function but higher ICC (max 10 μA vs. 80 μA at 3.6 V) and no IOFF circuitry. | Lacks power-down isolation - unsuitable for hot-swap or partial-power systems. | Select only if IOFF is unnecessary and TI supply chain preference applies. |
| 74LVCH16374ADGG | 16-bit version in 48-pin TSSOP; double density but requires PCB redesign and has higher layout complexity. | Used where higher channel count justifies added footprint and routing effort. | Choose only when scaling beyond 8 bits; not drop-in compatible due to pin count and package mismatch. |
Compared with SN74LVC374APWR, the 74ALVC374PW,112 provides essential IOFF protection for power sequencing, while versus 74LVCH16374ADGG it offers lower cost, smaller footprint, and simpler integration for standard 8-bit bus interfaces.

FAQ
Can 74ALVC374PW,112 operate reliably at 1.65 V supply?
Yes. The device is fully characterized from 1.65 V to 3.6 V per JEDEC JESD8-7. At 1.65 V, propagation delay is 6.4 ns max and setup time remains 0.8 ns - verified across -40 °C to +125 °C. Input thresholds scale with VCC, ensuring correct logic interpretation at minimum voltage.
What happens to internal flip-flop states when OE is HIGH?
Internal flip-flop states remain unchanged when OE is HIGH. The OE signal affects only output drivers - placing Q0–Q7 in high-impedance mode without altering stored data. Flip-flops continue sampling D-inputs on each CP rising edge regardless of OE state.
Is the TSSOP20 package (SOT360-1) lead-free and RoHS compliant?
Yes. The 74ALVC374PW,112 uses a lead-free, halogen-free, RoHS-compliant TSSOP20 package per Nexperia's product compliance documentation. Solder profile follows IPC/JEDEC J-STD-020D for MSL3 handling, with peak reflow temperature of 260 °C.
Does this device support hot-plug insertion in live backplanes?
Yes - enabled by the IOFF circuit. When VCC = 0 V during insertion, IOFF forces outputs into high-impedance and blocks backflow current up to ±50 mA, preventing damage to powered downstream circuitry. This behavior is tested per JESD78 and documented in Section 7 of the datasheet.
