Product details
Overview
74FCT162374ATPAG from Renesas Electronics is a 16-bit edge-triggered D-type register with 3-state outputs, designed for high-speed data synchronization and bus interface buffering in industrial systems. It operates at 5V ±10%, delivers ±24mA balanced output drive, achieves typical tPLH/tPHL ≤6.5ns, and supports dual 8-bit or unified 16-bit operation via independent clock and output-enable controls.
For engineers reviewing the 74FCT162374ATPAG datasheet, 74FCT162374ATPAG pinout, 74FCT162374ATPAG application, or 74FCT162374ATPAG equivalent, key selection criteria include industrial-temperature operation (–40°C to +85°C), low ground bounce (<0.6V), sub-250ps output skew, and TSSOP-48 package compatibility with legacy FCT16374T and ABT16374 designs.
Technical Context
This device implements two independent 8-bit D-register banks sharing no internal logic coupling-each bank has dedicated clock (1CLK/2CLK) and output-enable (1OE/2OE) inputs, enabling asynchronous control of output states while maintaining synchronous data capture. All 16 data inputs (1D1–1D8, 2D1–2D8) are TTL-compatible with hysteresis-enhanced noise immunity.
Output drivers integrate current-limiting resistors to suppress ground bounce and undershoot, eliminating need for external series termination. The 3-state outputs (1O1–1O8, 2O1–2O8) exhibit matched rise/fall times and controlled VOLP/VOH performance across full industrial temperature range under 5V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5.0V ±10% - compatible with standard 5V TTL/CMOS logic rails without level-shifting |
| tPLH / tPHL | ≤6.5ns max (CL = 50pF, RL = 500Ω) - enables reliable operation in ≥150MHz system clocks |
| Output Drive | ±24mA - sufficient to drive 50Ω transmission lines or multiple LVTTL inputs directly |
| tSK(o) | <0.5ns typical - ensures deterministic timing alignment across all 16 outputs for parallel bus integrity |
| Operating Temp | –40°C to +85°C - qualified for industrial control, motor drives, and factory automation environments |
| Input Hysteresis | 100mV - improves noise margin on clock and control lines in electrically noisy settings |
| VOL / VOH | ≤0.55V @ 24mA / ≥2.4V @ –24mA - guarantees robust logic-level compatibility with 5V CMOS and TTL families |
Pinout & Package
TSSOP-48 package (4.4mm × 12.5mm body, 0.5mm pitch); thermally enhanced with exposed thermal pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1D1–1D8, 2D1–2D8 | Data Inputs | Asynchronous parallel data inputs; each bank accepts 8-bit word synchronized on respective clock edge |
| 1CLK, 2CLK | Clock Inputs | Positive-edge-triggered clocks; independent timing control per 8-bit bank |
| 1OE, 2OE | Output Enable (Active LOW) | 3-state control per bank; asserts high-impedance when HIGH, enables outputs when LOW |
| 1O1–1O8, 2O1–2O8 | 3-State Outputs | Registered, buffered outputs with current-limited drivers; flow-through pin arrangement simplifies PCB routing |
| VCC (Pins 4, 9, 24, 37, 40) | Power Supply | Multiple distributed VCC pins reduce power delivery impedance and improve decoupling effectiveness |
| GND (Pins 2, 6, 10, 22, 23, 30, 31, 32, 42, 43) | Ground | 10 dedicated GND pins minimize ground bounce and support simultaneous switching of all 16 outputs |
Key Features
| Feature | Design Value |
|---|---|
| Balanced ±24mA Output Drivers | Eliminates need for external series termination resistors and reduces board component count |
| Flow-Through Pinout | Input-to-output signal path alignment minimizes trace length mismatch and skew in high-speed layouts |
| Hysteresis on All Inputs | 100mV input threshold margin prevents false triggering from EMI or crosstalk on clock/control lines |
| Low Ground Bounce (VOLP < 0.6V) | Enables clean multi-bit switching without compromising signal integrity on shared power/ground planes |
| Dual-Bank Architecture | Allows independent clocking and 3-state control of two 8-bit groups-ideal for split-bus or time-multiplexed interfaces |
Applications
| Industrial PLC Backplane Interface | Automated Test Equipment (ATE) Data Capture |
|---|---|
|
Use Scenario: Synchronizing parallel sensor data streams from multiple I/O modules into a central controller over a 16-bit backplane bus.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit registered bus interface applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74FCT16374ATPAG | Single 16-bit register with common clock and OE; lacks dual-bank flexibility | Suitable only where unified clocking and enable control suffice | Select when simplified control logic outweighs need for independent bank timing |
| SN74ALVTH16374GR | 2.5V/3.3V supply only; higher speed (tPD ≤3.2ns) but incompatible with 5V systems | Requires level translation or redesign for 5V legacy buses | Choose only for new 3.3V designs prioritizing speed over voltage compatibility |
Compared with 74FCT162374ATPAG, the 74FCT16374ATPAG offers simpler control but forfeits dual-clock capability, while the SN74ALVTH16374GR delivers faster timing at the cost of 5V incompatibility-making 74FCT162374ATPAG optimal for industrial 5V bus extensions requiring flexible timing and proven reliability.

FAQ
What is the operating voltage range for the 74FCT162374ATPAG?
The 74FCT162374ATPAG operates at VCC = 5.0V ±10%, meaning its valid supply range is 4.5V to 5.5V. This specification is strictly defined in the DC Electrical Characteristics table and validated across the full industrial temperature range (–40°C to +85°C). Operation outside this window may result in undefined logic states or degraded timing performance.
Does the 74FCT162374ATPAG support independent clocking of its two 8-bit sections?
Yes, the 74FCT162374ATPAG features fully independent clock inputs: 1CLK controls the first 8-bit register bank (1D1–1D8 → 1O1–1O8), and 2CLK controls the second (2D1–2D8 → 2O1–2O8). This architecture allows asynchronous data capture across banks, enabling time-multiplexed bus protocols or staggered sampling without inter-bank timing constraints.
What is the maximum output skew specified for the 74FCT162374ATPAG?
The 74FCT162374ATPAG guarantees typical output skew (tSK(o)) of less than 0.5ns between any two outputs switching in the same direction. This parameter is design-guaranteed and applies across all 16 outputs (1O1–1O8 and 2O1–2O8) under standard load conditions (CL = 50pF, RL = 500Ω), ensuring tight timing alignment critical for parallel bus integrity.
Is the 74FCT162374ATPAG pin-compatible with the ABT16374?
Yes, the 74FCT162374ATPAG is explicitly documented by Renesas as a plug-in replacement for the ABT16374 in on-board bus interface applications. Its pinout, function table, and AC/DC electrical specifications align to enable direct substitution without PCB layout modification-though users should verify timing margins in their specific clock frequency and loading conditions.
What package type does the 74FCT162374ATPAG use, and what are its key mechanical features?
The 74FCT162374ATPAG uses a TSSOP-48 package (Thin Shrink Small Outline Package, Green), measuring 4.4mm × 12.5mm with 0.5mm lead pitch. It includes 10 dedicated GND pins and 5 VCC pins distributed across the perimeter to minimize power delivery impedance and suppress ground bounce during simultaneous 16-bit switching events.
