Product details
Overview
74LVCH16374APVG from Renesas Electronics (formerly IDT) is a 3.3V CMOS 16-bit edge-triggered D-type flip-flop with 3-state outputs, 5V-tolerant I/O, bus-hold, and ±24mA drive strength. It operates across –40°C to +85°C, supports mixed 3.3V/5V systems, and functions as a high-speed data synchronization register in telecom and industrial control interfaces.
For engineers reviewing the 74LVCH16374APVG datasheet, 74LVCH16374APVG pinout, 74LVCH16374APVG application, or 74LVCH16374APVG equivalent, key selection criteria include its dual 8-bit/16-bit clock-enable architecture, output skew <500ps, bus-hold input retention, 5V-tolerant I/O compatibility, and SSOP-48 package footprint for board-level voltage translation and noise-immune data latching.
Technical Context
The 74LVCH16374APVG implements two independent 8-bit registers or one unified 16-bit register via shared clock (CLK) and separate output-enable (OE) controls per bank. Its dual-metal CMOS process enables low static power (0.4μW typ.) while maintaining 150MHz max clock frequency and sub-5ns propagation delay (tPLH/tPHL).
All 32 I/O pins-including D, Q, CLK, and OE-are 5V tolerant and feature hysteresis (100mV typ.) for noise margin enhancement. Bus-hold circuitry actively sustains last valid logic state on floating inputs, eliminating external pull resistors in hot-swap and partial-power-down scenarios.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7V–3.6V; supports industrial 3.3V systems with ±0.3V tolerance and extended operation down to 2.7V. |
| Output Drive | ±24mA per output; drives moderate-to-heavy capacitive loads without speed degradation in backplane or bus applications. |
| tPLH / tPHL | 1.5–4.5ns at VCC = 3.3V; ensures tight timing alignment for high-speed data capture in synchronous interfaces. |
| tSK(o) | <500ps output skew; guarantees deterministic phase relationship between outputs within same package for parallel data paths. |
| Bus-Hold Current | ±75μA sustain current (VCC = 3V); maintains stable logic levels during signal glitches or unconnected inputs. |
| Input Hysteresis | 100mV typical; improves noise immunity in electrically noisy industrial environments without external filtering. |
| ESD Rating | >2000V HBM, >200V MM; meets MIL-STD-883 requirements for robust handling in manufacturing and field deployment. |
Pinout & Package
74LVCH16374APVG is housed in a 48-pin Shrink Small Outline Package (SSOP), green RoHS-compliant, with 0.5mm pitch and standard JEDEC MO-153 footprint. Pin layout follows flow-through organization-inputs on left, outputs on right-to minimize trace crossovers and reduce PCB routing complexity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1D1–1D8, 2D1–2D8 | Data Inputs (Bank 1 & Bank 2) | Asynchronous 5V-tolerant inputs accepting 3.3V or 5V logic; each features bus-hold and hysteresis. |
| 1CLK, 2CLK | Clock Inputs (Bank 1 & Bank 2) | Edge-triggered (↑) clocks controlling latch timing per bank; support independent or common clocking. |
| 1OE, 2OE | Output Enable (Active LOW) | 3-state control per bank; enables independent tri-state management of 8-bit output groups. |
| 1Q1–1Q8, 2Q1–2Q8 | 3-State Outputs (Bank 1 & Bank 2) | ±24mA drive strength, 5V-tolerant, with fast enable/disable times (tPZH/tPHZ ≤ 5.5ns). |
| VCC, GND (x4) | Power & Ground Terminals | Multiple VCC/GND pairs reduce switching noise and improve power integrity across high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| 5V-Tolerant I/O | Enables direct interfacing between 3.3V logic and legacy 5V peripherals without level shifters. |
| Integrated Bus-Hold | Eliminates need for external pull-up/down resistors on unused or intermittently driven inputs. |
| Dual-Bank Architecture | Allows flexible configuration as two independent 8-bit registers or one synchronized 16-bit register. |
| Low Output Skew | Sub-500ps skew ensures simultaneous valid data across all 16 outputs for time-critical parallel transfers. |
| Hot-Insertion Support | IOFF leakage <±50μA at VCC = 0V prevents back-driving and system disruption during live board insertion. |
Applications
| Telecom Line Card Interface | Industrial PLC I/O Expansion |
|---|---|
Use Scenario: Synchronizing parallel status/data signals between FPGA-based control logic and multi-channel analog front-ends in carrier-grade line cards.

IC Role / Device Role / Timing Role: High-speed data register capturing parallel test results from DUTs before serial upload to host controller. Use Value: 150MHz max clock rate supports >100MSPS test throughput; low ICCZ (10μA typ.) minimizes standby power in multi-channel rack systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit 3-state D-type register applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16374ADGGR | TI part in TSSOP-48; identical 3.3V operation, 5V tolerance, and bus-hold, but tSK(o) rated ≤600ps (vs. ≤500ps). | Same mixed-voltage buffering use case; slightly higher skew may affect ultra-high-speed parallel timing margins. | Select SN74LVC16374ADGGR if TSSOP-48 footprint preferred and skew budget allows +100ps tolerance. |
| 74ALVCH16374PAG | IDT/Renesas variant in TSSOP-48; identical specs except extended VCC range (2.3V–3.6V) and lower ICCZ (5μA vs. 10μA). | Better suited for battery-powered or low-quiescent systems; otherwise functionally interchangeable in industrial temperature range. | Choose 74ALVCH16374PAG when operating below 2.7V VCC or minimizing standby current is critical. |
Compared with SN74LVC16374ADGGR and 74ALVCH16374PAG, the 74LVCH16374APVG offers the tightest output skew (≤500ps) and optimal balance of drive strength, noise immunity, and industrial temperature reliability in SSOP-48-making it preferred for timing-critical telecom and control applications where layout-constrained SSOP is acceptable.

FAQ
What is the operating temperature range for the 74LVCH16374APVG?
The 74LVCH16374APVG is rated for industrial temperature operation from –40°C to +85°C. This range is fully supported across all electrical specifications including propagation delay, output drive, and bus-hold functionality. The device's thermal design and dual-metal CMOS process ensure stable performance under continuous operation within this envelope, making it suitable for deployment in factory automation, base stations, and outdoor telecom enclosures where ambient conditions vary widely.
Does the 74LVCH16374APVG support hot insertion?
Yes, the 74LVCH16374APVG supports hot insertion due to its IOFF specification (±50μA at VCC = 0V) and 5V-tolerant I/O structure. When VCC is unpowered, the inputs and outputs remain high-impedance and non-backdriving, preventing interference with live backplanes or neighboring powered components. This behavior is verified per JEDEC JESD78 and enables safe module replacement in redundant telecom or industrial control systems without system shutdown.
How does bus-hold functionality work on the 74LVCH16374APVG?
The 74LVCH16374APVG integrates bus-hold circuitry on all data and control inputs (1D1–1D8, 2D1–2D8, 1CLK, 2CLK, 1OE, 2OE). When an input floats, internal feedback sustains the last valid logic state using ±75μA typical hold current. This eliminates external pull resistors, reduces BOM count, and prevents metastability in partially configured systems-especially valuable in modular I/O designs where connectors may be temporarily unmated.
What is the maximum clock frequency supported by the 74LVCH16374APVG?
The 74LVCH16374APVG supports a maximum clock frequency (fMAX) of 150MHz at VCC = 3.3V ± 0.3V and TA = 25°C. This rating is guaranteed across the full industrial temperature range (–40°C to +85°C) with appropriate load conditions (CL ≤ 50pF). The 150MHz capability enables use in high-throughput data acquisition, pattern generation, and real-time control loops where cycle-accurate latching of 16-bit parallel words is required.
Is the 74LVCH16374APVG pin-compatible with other 16-bit LVC flip-flops?
The 74LVCH16374APVG shares the same 48-pin SSOP footprint and pinout as industry-standard 16-bit LVC registers including SN74LVC16374A variants, but differs in bus-hold integration and skew performance. While not drop-in compatible with non-bus-hold versions (e.g., 74LVC16374A), its pin mapping matches IDT's own 74LVCH16374A family. Layout reuse is possible when migrating from earlier IDT LVC parts, provided bus-hold behavior and tighter skew are accounted for in timing analysis.
