Overview
74FCT163374APAG from Renesas Electronics (formerly IDT) is a 3.3V CMOS 16-bit edge-triggered D-type register with 3-state outputs, dual 8-bit or unified 16-bit clock/enable control, rail-to-rail output swing, and ±60 mA drive capability. It operates across –40°C to +85°C and supports mixed 3.3V/5V system interfacing in data synchronization and buffering applications.
For engineers reviewing the 74FCT163374APAG datasheet, 74FCT163374APAG pinout, 74FCT163374APAG application, or 74FCT163374APAG equivalent, key selection criteria include tPLH/tPHL ≤ 6.5 ns at 3.3 V, output skew < 0.5 ns, 3.3 V ±0.3 V supply tolerance, industrial temperature range support, and TSSOP-48 package compatibility with 500 Ω load and 50 pF capacitance test conditions.
Technical Context
This device implements two independent 8-bit registers or one 16-bit register via shared clock (xCLK) and active-low output enable (xOE) controls per bank. Its flow-through pin layout minimizes signal crosstalk and simplifies PCB routing for high-density bus interfaces.
All inputs feature hysteresis (150 mV typical), enabling robust noise immunity in noisy industrial environments. Inputs accept both 3.3 V and 5 V logic levels, allowing seamless level translation without external circuitry in mixed-supply systems.
Key Specifications

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 |
|---|---|---|---|
| SN74ALVCH16374DGGR | Lower VCC range (1.65–3.6 V); higher max fCP (150 MHz); no 5 V-tolerant inputs | Requires external level shifters in mixed 5 V/3.3 V systems; better suited for pure low-voltage, high-frequency designs | Select when operating exclusively at 1.8 V or 2.5 V and requiring >100 MHz clock rates |
| 74LVC16374APAG | Same TSSOP-48 package; 5 V-tolerant inputs; slower tPLH/tPHL (7.1 ns max); lower drive (±24 mA) | Adequate for cost-sensitive industrial I/O expanders where timing margin >1 ns is available | Select when budget constraints outweigh need for sub-7 ns timing or ±60 mA drive |
Compared with SN74ALVCH16374DGGR and 74LVC16374APAG, the 74FCT163374APAG uniquely balances 5 V input tolerance, industrial temperature operation, sub-7 ns timing, and ±60 mA drive-making it optimal for legacy-compatible, noise-immune, high-reliability bus interfaces.

FAQ
What is the maximum clock frequency supported by the 74FCT163374APAG?
The 74FCT163374APAG does not specify a maximum clock frequency in its datasheet; instead, it guarantees tPLH/tPHL ≤ 6.5 ns at VCC = 3.3 V, CL = 50 pF, and RL = 500 Ω. Based on this, reliable operation up to ≥100 MHz is achievable in well-designed PCB layouts with controlled impedance and minimal trace capacitance. The 74FCT163374APAG's performance is validated under industrial timing conditions-not rated for continuous operation above 150 MHz without derating.
Does the 74FCT163374APAG support 5 V logic inputs while powered at 3.3 V?
Yes, the 74FCT163374APAG explicitly supports 5 V-tolerant inputs on all non-I/O pins (including xCLK and xOE) and I/O pins (xDx), with VIH up to 5.5 V for inputs and up to VCC + 0.5 V for I/O terminals. This capability is confirmed in the Absolute Maximum Ratings table and DC Electrical Characteristics section of the official Renesas datasheet for the 74FCT163374APAG.
What is the function of the dual xOE and xCLK inputs on the 74FCT163374APAG?
The 74FCT163374APAG features two independent clock (1CLK, 2CLK) and output enable (1OE, 2OE) inputs to support flexible configuration: either two separate 8-bit registers (e.g., for byte-lane control) or one unified 16-bit register (by tying clocks and OEs together). This architecture enables precise bus segmentation and timing isolation-critical in applications like PCI-to-local bus bridging where upper and lower data bytes require independent gating.
Is the 74FCT163374APAG RoHS compliant and lead-free?
Yes, the 74FCT163374APAG is RoHS compliant and lead-free. Per Renesas' ordering information and package documentation, the "G" suffix in the package code (PAG48) denotes green (halogen-free, lead-free) construction, and the part meets JEDEC J-STD-020 moisture sensitivity level 3 requirements. Full compliance documentation is available in Renesas' official product change notices for the 74FCT163374APAG.
How does the 74FCT163374APAG handle ground bounce during simultaneous switching?
The 74FCT163374APAG limits ground bounce to 0.3 V typical through four dedicated GND pins (Pins 3, 18, 35, 48) and optimized internal bonding. This design reduces shared-impedance coupling during 16-bit simultaneous output transitions-verified in characterization tests per JEDEC standards. The 74FCT163374APAG's low ground bounce directly improves signal integrity in high-noise industrial environments such as motor drive control cabinets.
