Product details
Overview
FCT162374ATPVCTG4 from Texas Instruments is a 16-bit edge-triggered D-type register with dual 8-bit register capability, balanced 24 mA output drivers, 6.5 ns max propagation delay (CLK to O), and industrial temperature range (−40°C to +85°C). It operates at 5V ±10%, supports partial-power-down via Ioff, and is optimized for driving transmission lines in high-speed bus applications.
For engineers reviewing the FCT162374ATPVCTG4 datasheet, FCT162374ATPVCTG4 pinout, FCT162374ATPVCTG4 application, or FCT162374ATPVCTG4 equivalent, this device delivers low ground bounce (<0.6 V), flow-through pinout for simplified PCB layout, and TSSOP/SSOP package compatibility - critical for signal integrity in dense digital systems.
Technical Context
The FCT162374ATPVCTG4 implements two independent 8-bit registers sharing common clock (CLK) and output enable (OE) inputs, enabling flexible 8- or 16-bit data latching. Its balanced 24 mA drivers incorporate internal current-limiting resistors to minimize undershoot and reduce need for external termination.
Designed for 5V TTL-compatible operation, it features Ioff circuitry that disables outputs during power-down to prevent backflow current, and edge-rate control that significantly improves noise immunity. Typical output skew is <0.5 ns across same-package outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5 V ±10% - ensures compatibility with legacy 5V TTL logic families and stable operation across industrial voltage variation. |
| Propagation Delay | 6.5 ns max (CLK to O) - enables reliable timing in high-speed bus interfaces up to ~150 MHz system clock domains. |
| Output Drive | ±24 mA balanced - provides matched sourcing/sinking for controlled impedance line driving without external resistors. |
| Ground Bounce (VOLP) | <0.6 V at VCC = 5 V, TA = 25°C - reduces switching noise coupling into shared ground planes in multi-channel systems. |
| Operating Temperature | −40°C to +85°C - certified for use in industrial control, telecom infrastructure, and automotive under-hood auxiliary modules. |
| Ioff Support | Yes - prevents damaging current backflow when powered down, enabling safe hot-swap and partial-power-down system architectures. |
| Package | 48-pin SSOP (DL), 300-mil width - compact surface-mount footprint with JEDEC MO-118 compliance and 0.025" pitch for high-density routing. |
Pinout & Package
48-pin Shrink Small Outline Package (SSOP), DL package type, 300-mil body width, JEDEC MO-118 compliant, 0.025" lead pitch, 1.2 mm max height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE | Active-low three-state output enable | Independent control of two 8-bit output groups; assertion places respective outputs in high-impedance state for bus sharing. |
| 1CLK, 2CLK | Positive-edge clock input | Registers data on rising edge; separate clocks allow asynchronous latching of two data streams. |
| 1D1–1D8, 2D1–2D8 | Data inputs | Two sets of 8-bit parallel inputs; each group latched independently by its associated clock and OE. |
| 1O1–1O8, 2O1–2O8 | Three-state outputs | 16 total CMOS-compatible outputs with 24 mA drive strength; high-Z state enabled by OE assertion. |
| VCC, GND (×4 each) | Power and ground terminals | Distributed supply/ground pins reduce simultaneous switching noise and improve decoupling effectiveness. |
Key Features
| Feature | Design Value |
|---|---|
| Balanced 24 mA output drivers | Enables direct transmission-line driving (e.g., 50 Ω traces) without series termination, reducing BOM count and board area. |
| Flow-through pinout | Input-to-output signal path alignment minimizes trace length and crosstalk in high-speed parallel buses. |
| Ioff partial-power-down support | Prevents backflow current when VCC = 0 V and outputs are driven externally - essential for mixed-voltage or hot-plug systems. |
| Edge-rate control circuitry | Reduces EMI and ground bounce by limiting slew rate, improving signal integrity in noise-sensitive environments. |
| Low output skew (<0.5 ns) | Ensures tight timing alignment across all 16 outputs - critical for synchronous data capture in memory interfaces or FPGA I/O expansion. |

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 |
|---|---|---|---|
| CY74FCT162374CTPVCT | 5.2 ns max propagation delay (vs. 6.5 ns); otherwise identical electrical specs and pinout. | Better suited for systems requiring tighter timing margins, e.g., >150 MHz clock domains or ultra-low-jitter sampling. | Select when propagation delay is the dominant timing constraint and 5.2 ns performance is required. |
| 74FCT162374ATPACT | TSSOP-48 (DGG) package instead of SSOP-48 (DL); identical speed grade and functionality. | Preferred for designs prioritizing smaller footprint (240-mil vs. 300-mil width) and higher pin density layouts. | Choose for space-constrained boards where 0.6 mm narrower package enables tighter routing or reduced layer count. |
Compared with CY74FCT162374CTPVCT, FCT162374ATPVCTG4 trades 1.3 ns of propagation delay for broader availability and cost efficiency; versus 74FCT162374ATPACT, it offers identical logic performance but in a wider, more manufacturable SSOP package with superior thermal dissipation and handling robustness.

FAQ
What is the maximum clock frequency supported by the FCT162374ATPVCTG4?
The FCT162374ATPVCTG4 does not specify a maximum clock frequency directly, but its 6.5 ns max propagation delay and 5.0 ns minimum clock pulse width imply reliable operation up to approximately 150 MHz in well-designed systems. Timing裕度 depends on setup/hold (2.0 ns / 1.5 ns) and board-level signal integrity - actual usable frequency must be validated per application layout and load conditions. The FCT162374ATPVCTG4 is rated for industrial temperature and 5V operation, not for sustained GHz-range clocks.
Does the FCT162374ATPVCTG4 support mixed-voltage operation (e.g., 3.3V inputs with 5V VCC)?
No - the FCT162374ATPVCTG4 is a 5V-only device. Its input thresholds (VIH = 2.0 V min, VIL = 0.8 V max) are TTL-compatible but not guaranteed for reliable 3.3V logic level interfacing without external level translation. Driving inputs with 3.3V signals risks marginal HIGH recognition, especially over temperature and process variation. For mixed-voltage systems, the FCT162374ATPVCTG4 requires compatible 5V logic sources or dedicated level shifters.
How does the Ioff feature function in the FCT162374ATPVCTG4 during partial power-down?
The Ioff circuitry in the FCT162374ATPVCTG4 actively disables all outputs when VCC = 0 V, regardless of input or OE state, preventing current backflow from live buses into the unpowered device. This protects both the FCT162374ATPVCTG4 and upstream drivers during hot-swap or staged power sequencing. Ioff is specified at ±1 µA leakage and functions across −40°C to +85°C - a key enabler for fault-tolerant industrial system design.
Can the FCT162374ATPVCTG4 be used as two independent 8-bit registers?
Yes - the FCT162374ATPVCTG4 contains two fully independent 8-bit register sections (1D–1O and 2D–2O), each with dedicated clock (1CLK/2CLK) and output enable (1OE/2OE) inputs. They share no internal coupling; data latched on one side does not affect the other. This architecture allows concurrent latching of two separate data streams, such as control/status words or dual-channel sensor data, making the FCT162374ATPVCTG4 highly flexible in multi-bus systems.
What is the meaning of "G4" in the part number FCT162374ATPVCTG4?
The "G4" suffix in FCT162374ATPVCTG4 denotes TI's Green (RoHS-compliant, Pb-free, and free of bromine/antimony flame retardants) material composition and CU NIPDAU lead finish. It also indicates Moisture Sensitivity Level 1 (MSL-1), meaning unlimited floor life at ≤30°C/60% RH and peak reflow temperature of 260°C - suitable for standard lead-free assembly processes without baking requirements. This suffix confirms full environmental compliance per TI's eco-plan.
