Product details
Overview
74FCT16374ETPVG from Renesas Electronics is a 16-bit edge-triggered D-type register with 3-state outputs, designed for high-speed data synchronization and buffering in industrial backplane and bus interface applications. It operates at VCC = 5V ±10%, delivers ±32mA/64mA drive strength, exhibits typical tPLH/tPHL ≤ 3.7ns, and supports industrial temperature range (–40°C to +85°C).
For engineers reviewing the 74FCT16374ETPVG datasheet, 74FCT16374ETPVG pinout, 74FCT16374ETPVG application, or 74FCT16374ETPVG equivalent, key selection criteria include output skew < 0.5ns, live-insertion capability via power-off disable outputs, dual 8-bit or unified 16-bit clocking configuration, and SSOP-48 package compatibility with high-density PCB layouts.
Technical Context
The 74FCT16374ETPVG implements a dual-rail CMOS architecture with hysteresis-equipped inputs for noise immunity and flow-through pin organization to minimize trace routing complexity. Its clock and output-enable controls are partitioned per 8-bit bank (1CLK/1OE and 2CLK/2OE), enabling independent or synchronized operation of two 8-bit registers.
Each output buffer features active-low 3-state control, power-off disable functionality (IOFF ≤ ±1μA at VCC = 0V), and low ground bounce (VOLP < 1.0V). The device meets MIL-STD-883 ESD requirements (>2000V human body model) and supports TTL-level input compatibility (VIH = 2.0V min, VIL = 0.8V max).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5.0V ±10% - ensures compatibility with legacy 5V TTL/CMOS systems without level-shifting. |
| tPLH / tPHL | ≤3.7ns (max) at CL = 50pF - enables reliable operation in high-speed address/data latching up to ~270MHz clock domains. |
| tSK(o) | <0.5ns - guarantees tight timing correlation across all 16 outputs for synchronous bus capture. |
| IOL / IOH | 64mA / –32mA - drives heavy capacitive loads (e.g., >100pF backplanes) and multiple TTL inputs without external buffers. |
| Operating Temp | –40°C to +85°C - qualified for industrial control, motor drives, and factory automation environments. |
| IOFF (Power-off) | ±1μA max at VCC = 0V - permits hot-plug insertion into live backplanes without signal contention or damage. |
| CIN / COUT | 6pF / 8pF max - minimizes switching noise and reduces dynamic current consumption in high-frequency operation. |
Pinout & Package
74FCT16374ETPVG is housed in a 48-pin Shrink Small Outline Package (SSOP), designated PVG48, with 0.5mm lead pitch and JEDEC MO-153 compliant footprint. The package supports reflow soldering and provides mechanical robustness for industrial board-level reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1O1–1O8, 2O1–2O8 | 3-State Outputs | Individually controlled by respective xOE; high-impedance when xOE = HIGH, enabling shared bus arbitration. |
| 1D1–1D8, 2D1–2D8 | Data Inputs | Edge-triggered on rising xCLK; latched values appear at corresponding xOx after propagation delay. |
| 1CLK, 2CLK | Positive-edge Clock Inputs | Enable independent or common-clock operation of two 8-bit sections; no internal clock distribution delay. |
| 1OE, 2OE | Active-Low Output Enables | Assert LOW to enable outputs; HIGH places outputs in high-Z state - critical for bus isolation. |
| VCC (Pins 4, 11, 20, 24, 39, 40, 47) | Power Supply | Multiple VCC pins reduce IR drop and improve noise rejection across wide die area. |
| GND (Pins 3, 10, 19, 23, 30, 38, 46) | Ground | Distributed GND pins provide low-inductance return paths and stabilize output switching transients. |
Key Features
| Feature | Design Value |
|---|---|
| High-Speed Register Logic | 3.7ns max propagation delay enables use in 200+ MHz system clocks with margin for setup/hold timing. |
| Live Insertion Support | Power-off disable outputs (IOFF ≤ ±1μA) prevent backdrive damage during hot-swap of daughter cards or modules. |
| Noise-Immune Inputs | Hysteresis ≥100mV on all inputs suppresses false triggering from EMI or slow-rising signals on long traces. |
| Flow-Through Pinout | Input-to-output signal path alignment simplifies PCB layout, reduces crosstalk, and avoids layer stacking penalties. |
| Industrial Temperature Rating | Guaranteed operation from –40°C to +85°C supports deployment in uncontrolled ambient environments like factory floors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit registered buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74FCT16374CTPVG | Slower speed grade: tPLH/tPHL ≤ 5.2ns (vs. 3.7ns); otherwise identical pinout, function, and DC specs. | Suitable for lower-frequency systems (<100MHz) where timing margin is less constrained. | Select when cost sensitivity outweighs need for maximum speed; same PCB layout and firmware. |
| SN74ALVTH16374DGGR | 3.3V-only supply (1.65–3.6V); different pinout; higher speed (tPD ≤ 2.8ns) but incompatible voltage domain. | Requires full level-shifting infrastructure; not drop-in for 5V systems. | Choose only for new 3.3V designs prioritizing lower power and higher speed - not a direct replacement. |

FAQ
What is the maximum clock frequency supported by the 74FCT16374ETPVG?
The 74FCT16374ETPVG does not specify a maximum clock frequency in its datasheet, but its guaranteed tPLH/tPHL ≤ 3.7ns and tW (clock pulse width) ≥ 3ns imply reliable operation up to approximately 270MHz in ideal conditions. Real-world maximum frequency depends on load capacitance, trace impedance, and board layout - design validation at target speed is recommended before deployment.
Does the 74FCT16374ETPVG support mixed-voltage operation?
No, the 74FCT16374ETPVG is strictly a 5V device with VCC = 5.0V ±10% operating range. Its inputs are TTL-compatible (VIH ≥ 2.0V, VIL ≤ 0.8V), but it does not support 3.3V or lower supply voltages. Applying voltages outside the specified range may cause functional failure or permanent damage to the 74FCT16374ETPVG.
Can the 74FCT16374ETPVG be used as two independent 8-bit registers?
Yes, the 74FCT16374ETPVG supports dual 8-bit operation via separate clock (1CLK/2CLK) and output-enable (1OE/2OE) inputs. Each group of eight D-inputs and Q-outputs functions independently - allowing asynchronous latching, staggered enable timing, or distinct clock domains within a single package, as confirmed in the functional block diagram and truth table.
What is the purpose of hysteresis on the inputs of the 74FCT16374ETPVG?
The 74FCT16374ETPVG incorporates ≥100mV input hysteresis to increase noise immunity on slow-rising or electrically noisy signals. This prevents metastability and false triggering during signal transitions, especially on long PCB traces or in electrically harsh industrial environments - a verified design feature explicitly documented in the DC electrical characteristics table.
Is the 74FCT16374ETPVG RoHS compliant and lead-free?
Yes, the 74FCT16374ETPVG is RoHS compliant and lead-free. The datasheet revision history confirms removal of non-RoHS parts in 2009, and current ordering information (including PVG48 package code) aligns with Renesas' green manufacturing standards. The "G" suffix in package designation (e.g., PVG) denotes lead-free finish per J-STD-609.
