Product details
Overview
74FCT163374CPAG from Renesas Electronics (formerly IDT) is a 3.3V CMOS 16-bit edge-triggered D-type register with 3-state outputs, designed for data synchronization and buffering in mixed-voltage systems. It supports dual 8-bit or unified 16-bit operation via independent clock and output-enable controls, features rail-to-rail output swing, <250ps output skew, and operates across –40°C to +85°C.
For engineers reviewing the 74FCT163374CPAG datasheet, 74FCT163374CPAG pinout, 74FCT163374CPAG application, or 74FCT163374CPAG equivalent, key selection criteria include industrial-temperature 3.3V operation, 5.2ns max propagation delay (FCT163374C speed grade), 3-state enable timing, and compatibility with both 3.3V and 5V input drivers in bus interface and memory buffer designs.
Technical Context
The 74FCT163374CPAG implements two independent 8-bit register sections sharing no internal logic-each with dedicated clock (1CLK/2CLK) and active-low output-enable (1OE/2OE) inputs-enabling flexible partitioning of 16-bit data paths. Its dual-metal CMOS process ensures low ground bounce (0.3V typ.) and CMOS static power (0.4μW typ.).
All inputs incorporate hysteresis (150mV typ.) for noise immunity, and I/O pins tolerate up to VCC+0.5V, allowing safe interfacing with 5V drivers while powered at 3.3V. Output disable time is 5ns max, and setup/hold times are 2ns/1.5ns respectively, supporting high-speed synchronous capture.
Key Specifications

Pinout & Package
74FCT163374CPAG is housed in a 48-pin Thin Shrink Small Outline Package (TSSOP), 12.5mm × 6.1mm body, 0.5mm pitch, JEDEC MO-153 compliant, with exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1O1–1O8, 2O1–2O8 | 3-State Outputs | Eight-bit parallel outputs per section; high-impedance when respective xOE = HIGH |
| 1D1–1D8, 2D1–2D8 | Data Inputs | Synchronous data latching on rising xCLK edge; tolerant of 5V inputs |
| 1CLK, 2CLK | Positive-Edge Clocks | Independent clocks allow asynchronous registration of two 8-bit streams |
| 1OE, 2OE | Active-Low Output Enables | Enable/disable each 8-bit output bank independently; no bus contention risk |
| VCC (Pins 4, 11, 23, 36, 47) | Power Supply | Multiple VCC pins reduce IR drop and improve noise immunity across wide package |
| GND (Pins 3, 10, 22, 35, 48) | Ground | Distributed ground pins minimize ground bounce during simultaneous output switching |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Maximizes noise margin in noisy industrial environments by delivering full VCC/GND logic levels |

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 |
|---|---|---|---|
| 74FCT163374APAG | 5.2ns max tPLH vs. 5.2ns (same); A-grade has tighter tSU/tH specs (2ns/1.5ns identical), but C-grade offers same timing at lower cost | No functional difference in industrial-temp operation; A-grade typically used only where tighter characterization margins required | Select 74FCT163374CPAG for cost-sensitive industrial designs meeting nominal timing specs |
| SN74ALVCH16374DGGR | 3.3V-only inputs (no 5V tolerance); 6.7ns max tPLH; different pinout (no flow-through); 48-TSSOP but non-pin-compatible | Requires external level shifters for 5V interfaces; less suitable for mixed-voltage backplanes | Choose SN74ALVCH16374DGGR only if system uses exclusively 3.3V logic and layout allows rework |
Compared with 74FCT163374APAG, the 74FCT163374CPAG delivers identical timing performance at lower unit cost, while SN74ALVCH16374DGGR lacks 5V input tolerance and requires PCB redesign-making 74FCT163374CPAG the optimal choice for robust, mixed-voltage, industrial-grade buffering.

FAQ
What is the maximum clock frequency supported by the 74FCT163374CPAG?
The 74FCT163374CPAG does not specify a maximum clock frequency directly, but its 5.2ns max propagation delay (tPLH/tPHL) and 5ns min clock pulse width (tW) support reliable operation up to approximately 100 MHz in typical industrial conditions. Actual usable frequency depends on board layout, load capacitance, and supply stability-designers should verify timing margins using the device's published setup/hold (2ns/1.5ns) and skew (<0.5ns) parameters in their specific application. The 74FCT163374CPAG remains stable across its full –40°C to +85°C range.
Does the 74FCT163374CPAG support 5V input signals while operating at 3.3V VCC?
Yes, the 74FCT163374CPAG explicitly supports 5V-tolerant inputs: its VIH specification for I/O pins extends to VCC+0.5V, meaning it safely accepts 5V logic-high signals when powered at 3.3V. This capability eliminates the need for external level shifters in mixed-voltage systems. The 74FCT163374CPAG input structure includes hysteresis (150mV typ.) to further enhance noise immunity during 5V signal transitions, making it ideal for interfacing legacy 5V peripherals with modern 3.3V controllers.
How many independent register sections does the 74FCT163374CPAG contain?
The 74FCT163374CPAG contains two fully independent 8-bit register sections-labeled Section 1 (1D1–1D8, 1CLK, 1OE, 1O1–1O8) and Section 2 (2D1–2D8, 2CLK, 2OE, 2O1–2O8). Each section has its own clock and output-enable control, allowing asynchronous registration of two separate 8-bit data streams or coordinated 16-bit operation. This architecture is confirmed in the functional block diagram and pin description of the 74FCT163374CPAG datasheet and enables flexible bus partitioning without internal signal coupling.
What is the purpose of the flow-through pinout in the 74FCT163374CPAG package?
The flow-through pinout of the 74FCT163374CPAG-where data inputs occupy one side of the TSSOP package and corresponding 3-state outputs align directly opposite-minimizes trace length, reduces crosstalk, and simplifies PCB routing in high-density layouts. This physical organization supports clean signal integrity for parallel 16-bit buses and is especially valuable in industrial backplanes and telecom line cards. The 74FCT163374CPAG's pin mapping also distributes VCC and GND pins across the package to lower impedance paths and suppress ground bounce during simultaneous switching.
Is the 74FCT163374CPAG RoHS compliant and lead-free?
Yes, the 74FCT163374CPAG is RoHS compliant and lead-free. Per Renesas' updated ordering information and document history (May 2018 revision), all current 74FCT163374CPAG shipments meet RoHS Directive 2011/65/EU requirements. The "G" suffix in the package code (PAG48 → PAG) denotes green (halogen-free, lead-free) construction. No exemptions apply-the 74FCT163374CPAG uses matte tin lead finish and complies with JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) handling guidelines.
