Product details
Overview
74FCT163244CPFG from Renesas Electronics is a 3.3V CMOS 16-bit non-inverting buffer/line driver with quad-nibble, dual-byte, or full 16-bit 3-state control, rail-to-rail output swing, <250ps output skew, and industrial temperature range (–40°C to +85°C). It serves as a level translator between 3.3V and 5V logic in bus interface applications.
For engineers reviewing the 74FCT163244CPFG datasheet, 74FCT163244CPFG pinout, 74FCT163244CPFG application, or 74FCT163244CPFG equivalent, key selection criteria include 3-state enable timing (tPZH ≤ 6.2 ns), output drive strength (±60 mA), input hysteresis (150 mV), and compatibility with mixed-voltage backplane interfaces.
Technical Context
The 74FCT163244CPFG implements four independent 4-bit groups, each with dedicated active-low 3-state enable (xOE) and non-inverting data path (xAx → xYx). Its dual-metal CMOS process enables low ground bounce (0.3 V typ.) and rail-to-rail output swing for noise immunity in high-density PCB layouts.
All inputs accept 3.3V or 5V logic levels, enabling bidirectional voltage translation without external components. The device operates across VCC = 2.7V–3.6V and supports flow-through pinout for simplified trace routing - critical for backplane and memory subsystem signal integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7V to 3.6V - ensures robust operation across industrial power supply tolerances |
| tPZH / tPHZ | 1.5–6.2 ns - defines maximum enable/disable latency for synchronous bus arbitration |
| IOL / IOH | ±60 mA - supports driving 50 Ω transmission lines or multiple TTL loads |
| tSK(o) | < 0.5 ns - guarantees tight skew for parallel data capture across all 16 outputs |
| VH (Hysteresis) | 150 mV - improves noise rejection on slow-rising or noisy control signals |
| ICCL | 0.1–10 µA - enables ultra-low static power in always-on system management functions |
Pinout & Package
74FCT163244CPFG is supplied in a 48-pin TSSOP (Thin Shrink Small Outline Package) with 0.5 mm pitch, JEDEC MO-153 compliant, and RoHS-compliant green finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE–4OE | Active-low 3-state enable inputs | Independent control per 4-bit group; enables flexible bus segmentation |
| 1A1–4A4 | Non-inverting data inputs | Accept 3.3V or 5V logic; hysteresis enhances noise margin |
| 1Y1–4Y4 | Non-inverting 3-state outputs | Rail-to-rail swing (0–VCC); ±60 mA drive supports stubbed backplanes |
| VCC (Pins 4, 19, 20, 39, 48) | Power supply | Multiple distributed VCC pins reduce IR drop and improve high-frequency decoupling |
| GND (Pins 2, 13, 24, 30, 31, 40) | Ground reference | Six GND pins minimize ground bounce during simultaneous switching |
Key Features
| Feature | Design Value |
|---|---|
| Mixed-voltage interface capability | Inputs tolerate 5V while operating at 3.3V VCC - eliminates level-shifter ICs in 3.3V/5V hybrid systems |
| Flow-through pinout | Input and output pins aligned on opposite sides - reduces layer count and crosstalk in dense PCB routing |
| Low ground bounce (0.3 V typ.) | Enables reliable operation in high-speed parallel buses without added termination or layout constraints |
| Output skew < 250 ps | Ensures deterministic timing alignment across all 16 bits for synchronous data capture |
| ESD protection | >2000 V HBM and >200 V machine model - meets industrial handling and board-level reliability requirements |
Applications
| Industrial Backplane Interface | Memory Subsystem Buffering |
|---|---|
Use Scenario: Interfacing 5V legacy controllers to 3.3V DDR SDRAM address/control buses in programmable logic-based motion controllers. IC Role / Device Role / Timing Role: Non-inverting 3-state buffer with independent nibble enables; provides voltage translation and bus isolation.

IC Role / Device Role / Timing Role: Low-power (0.1 µA quiescent) 16-bit buffer with flow-through layout for minimal trace length. Use Value: Reduces BOM count by replacing eight 2-bit buffers; TSSOP package fits 8 mm × 6 mm space-constrained PCB areas. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit non-inverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16244ADGGR | 3.3V-only inputs (no 5V-tolerant); lower drive (±24 mA); 1.8V–3.6V VCC range | Not suitable for 5V-to-3.3V translation; better for pure 3.3V LVTTL systems with lower power budgets | Select when interfacing only 3.3V sources and board space allows larger 48-pin VQFN |
| 74ALVC16244PW,118 | Higher speed (tPLH ≤ 3.3 ns); same 5V-tolerant inputs; 1.65V–3.6V VCC | Better for sub-5 ns timing-critical paths but lacks industrial temp rating (–40°C to +85°C not guaranteed) | Select when absolute propagation delay matters more than extended temperature validation |
Compared with SN74LVC16244ADGGR and 74ALVC16244PW,118, the 74FCT163244CPFG uniquely combines 5V-tolerant inputs, industrial temperature certification, and sub-0.5 ns output skew - making it optimal for legacy-system upgrades requiring backward compatibility and field reliability.

FAQ
What is the operating temperature range for the 74FCT163244CPFG?
The 74FCT163244CPFG is rated for industrial temperature operation from –40°C to +85°C. This range is validated per the datasheet's "INDUSTRIAL TEMPERATURE RANGE" specification and applies across the full VCC range of 2.7V to 3.6V. All electrical parameters-including propagation delay, output drive, and input hysteresis-are guaranteed within this thermal envelope. The 74FCT163244CPFG does not support commercial or extended temperature grades.
Does the 74FCT163244CPFG support 5V-tolerant inputs?
Yes, the 74FCT163244CPFG supports 5V-tolerant inputs on all data (xAx) and enable (xOE) pins. Inputs can be driven directly from 5V TTL or CMOS sources while the device operates at VCC = 3.3V ± 0.3V. This capability is explicitly confirmed in the Functional Description section and enables use as a level translator in mixed-supply systems without external components. The 74FCT163244CPFG maintains guaranteed VIH/VIL thresholds up to 5.5V on input pins.
What package type is used for the 74FCT163244CPFG?
The 74FCT163244CPFG uses a 48-pin Thin Shrink Small Outline Package (TSSOP) with 0.5 mm lead pitch, identified by the "PFG" suffix in the ordering code. It is RoHS-compliant and green-finish (lead-free). This package is JEDEC MO-153 registered and features exposed thermal pad geometry optimized for industrial PCB assembly and reflow profiles. The 74FCT163244CPFG is not offered in SSOP or TVSOP variants under this specific part number.
How many independent 3-state control groups does the 74FCT163244CPFG provide?
The 74FCT163244CPFG provides four independent active-low 3-state enable inputs: 1OE, 2OE, 3OE, and 4OE - one per 4-bit nibble group. This architecture allows selective disabling of individual 4-bit segments (e.g., address vs. control lines) without affecting others. The 74FCT163244CPFG supports quad-nibble, dual-byte (pairs of nibbles), or full 16-bit bus control modes via external logic tied to these enables.
What is the maximum output skew specification for the 74FCT163244CPFG?
The 74FCT163244CPFG guarantees output skew (tSK(o)) of ≤ 0.5 ns across any two outputs switching in the same direction under identical load conditions. This value is design-guaranteed and verified per the Switching Characteristics table. Measured at CL = 50 pF and RL = 500 Ω with VCC = 3.3V, the 74FCT163244CPFG's skew performance ensures deterministic timing alignment critical for parallel data capture in backplane and memory applications.
