Product details
Overview
74FCT16374CTPVG 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 5V ±10%, delivers ±32mA/64mA output drive, exhibits typical tPLH/tPHL ≤ 5.2ns (CL = 50pF), and supports live insertion via power-off disable outputs.
For engineers reviewing the 74FCT16374CTPVG datasheet, 74FCT16374CTPVG pinout, 74FCT16374CTPVG application, or 74FCT16374CTPVG equivalent, key selection criteria include output skew < 0.5ns, industrial temperature range (–40°C to +85°C), dual 8-bit or unified 16-bit clocking architecture, and SSOP-48 package compatibility with high-density PCB layouts.
Technical Context
The 74FCT16374CTPVG implements two independent 8-bit registers sharing common clock and output-enable controls, enabling flexible partitioning of data paths. Its dual-metal CMOS process ensures low input leakage (≤1µA) and high noise immunity via input hysteresis.
Each output buffer provides TTL-compatible drive strength (–32mA IOH, 64mA IOL) and guarantees output ground bounce < 1.0V at VCC = 5V. The device supports flow-through pin organization to minimize trace routing complexity and signal skew across the 16-bit bus.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5.0V ±10% - compatible with standard industrial 5V rails; no external regulation required |
| tPLH / tPHL | ≤5.2ns max (CL = 50pF) - enables reliable operation at ≥100MHz system clock rates |
| tSK(o) | <0.5ns - ensures tight timing alignment across all 16 outputs for synchronous bus transfers |
| IOH / IOL | –32mA / +64mA - drives heavy capacitive loads (e.g., 50pF+ backplanes) without signal degradation |
| Operating Temp | –40°C to +85°C - qualified for uncontrolled industrial environments including factory automation |
| Input Hysteresis | 100mV - improves noise margin against EMI in electrically noisy control systems |
| Power-off Disable | Active at VCC = 0V - permits hot-swap board insertion without damaging downstream logic |
Pinout & Package
74FCT16374CTPVG is housed in a 48-pin Shrink Small Outline Package (SSOP), 0.300" wide, with 0.025" lead pitch and exposed thermal pad (not electrically connected). Package code PVG48 per Renesas ordering nomenclature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1O1–1O8, 2O1–2O8 | 3-State Outputs | Individually controlled by respective xOE; high-impedance when xOE = HIGH |
| 1D1–1D8, 2D1–2D8 | Data Inputs | Edge-triggered on rising xCLK; latched values appear at corresponding xOx after propagation delay |
| 1CLK, 2CLK | Clock Inputs | Rising-edge sensitive; each clocks its associated 8-bit section independently |
| 1OE, 2OE | Output Enable (Active LOW) | Drives respective 8-bit output group into high-Z when asserted HIGH |
| VCC (Pins 4, 11, 20, 28, 37, 44) | Power Supply | Multiple distributed VCC pins reduce supply inductance and improve noise rejection |
| GND (Pins 3, 10, 19, 27, 36, 43) | Ground | Multiple GND pins provide low-impedance return paths for all 16 drivers |
Key Features
| Feature | Design Value |
|---|---|
| Flow-through pin layout | Minimizes layer transitions and crosstalk in dense 16-bit bus routing; reduces PCB design cycle time |
| Live-insertion support | Outputs enter high-Z state when VCC = 0V, preventing bus contention during hot-swap operations |
| Dual 8-bit register mode | Enables independent clocking and output control of two 8-bit data streams using shared xOE/xCLK resources |
| Low output skew | Guaranteed <0.5ns skew between any two outputs ensures deterministic setup/hold timing across full bus width |
| TTL-compatible inputs | Accepts standard TTL voltage levels (VIH ≥ 2.0V, VIL ≤ 0.8V) without level-shifting circuitry |
Applications

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 |
|---|---|---|---|
| SN74FCT16374CPAG | TI version in TSSOP-48; identical AC/DC specs but different manufacturer qualification and traceability | No functional difference; suitable where TI sourcing or dual-sourcing is required | Select when TI's quality documentation or regional distribution preference applies |
| 74ALVC16374PW | NXP 3.3V-only variant (1.65–3.6V); lower drive (–24mA/24mA), higher speed (tPD ≈ 3.4ns), not 5V-tolerant | Requires level translation for 5V systems; unsuitable for direct 74FCT16374CTPVG drop-in | Choose only for new 3.3V designs prioritizing lower power and faster timing over 5V compatibility |
Compared with SN74FCT16374CPAG, the 74FCT16374CTPVG offers identical electrical behavior but distinct supply-chain provenance; versus 74ALVC16374PW, it provides native 5V operation and higher drive at the cost of higher voltage operation and slightly longer propagation delay.

FAQ
What is the maximum clock frequency supported by the 74FCT16374CTPVG?
The 74FCT16374CTPVG does not specify a maximum clock frequency in its datasheet; instead, it guarantees timing parameters such as tW (minimum clock pulse width) of 3ns and tSU/tH of 1.5ns/0ns. These values support reliable operation at ≥100MHz in typical 50pF load conditions. System-level timing must be verified using the full switching characteristics table and actual board parasitics.
Does the 74FCT16374CTPVG support independent clocking of its two 8-bit sections?
Yes, the 74FCT16374CTPVG features separate 1CLK and 2CLK inputs, allowing fully independent clocking of the first and second 8-bit register sections. This enables asynchronous data capture from two distinct sources or staggered updates within a single device, as confirmed by the functional block diagram and pin description table.
Is the 74FCT16374CTPVG pin-compatible with the 74FCT16374ATPVG or 74FCT16374ETPVG variants?
Yes, the 74FCT16374CTPVG shares identical pinout, package (PVG48 SSOP), and DC specifications with the AT and ET speed grades. The only differences are AC timing parameters: CT offers the fastest propagation (5.2ns), AT is mid-speed (6.5ns), and ET is slowest (3.7ns). All three are mechanically and electrically interchangeable in the same footprint.
What is the purpose of the multiple VCC and GND pins on the 74FCT16374CTPVG?
The 74FCT16374CTPVG allocates six VCC and six GND pins across the SSOP-48 package to minimize simultaneous switching noise and reduce power delivery impedance. This distributed power network stabilizes supply voltage during rapid 16-bit output transitions, directly supporting its specified 64mA IOL capability and low VOL performance under heavy capacitive loads.
Can the 74FCT16374CTPVG be used in mixed-voltage systems with 3.3V logic?
No - the 74FCT16374CTPVG is strictly a 5V device (VCC = 5.0V ±10%) and is not 5V-tolerant on inputs when operated at lower voltages. Its VIH/VIL thresholds (2.0V/0.8V) and output drive characteristics are optimized for 5V TTL/CMOS interfaces. Interfacing with 3.3V logic requires external level-shifting circuitry to avoid damage or unreliable operation.
