Product details
Overview
74FCT163244APVG8 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. It operates across –40°C to +85°C, supports mixed 3.3V/5V input interfacing, delivers rail-to-rail output swing, and features <250ps typical output skew. It is used in industrial backplane and bus interface applications requiring low ground bounce (0.3V typ.) and high noise immunity.
For engineers reviewing the 74FCT163244APVG8 datasheet, 74FCT163244APVG8 pinout, 74FCT163244APVG8 application, or 74FCT163244APVG8 equivalent, key selection criteria include its 3.3V supply range (2.7–3.6V), ±60mA output drive, 48-pin TSSOP package, 3-state enable logic (active-low), and compatibility with TTL-level inputs in mixed-voltage systems.
Technical Context
The 74FCT163244APVG8 implements a flow-through pinout architecture to simplify PCB layout and reduce signal crosstalk. Its four independent 4-bit sections each feature dedicated active-low 3-state enable inputs (1OE–4OE), allowing flexible bus segmentation and dynamic power gating.
Input hysteresis (150mV typ.) enhances noise margin against slow or noisy signals, while rail-to-rail output swing ensures robust logic level translation between 3.3V domains and legacy 5V peripherals. All inputs tolerate 5V logic levels regardless of VCC, enabling seamless voltage translation without external level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7V to 3.6V - supports extended industrial supply tolerance and brown-out resilience |
| Output Drive | ±60mA - sufficient for driving 50Ω transmission lines or multiple CMOS/TTL loads |
| tPLH / tPHL | 1.5ns (min), 4.8ns (max) - enables >200MHz bus operation with tight timing margins |
| tPZH / tPHZ | 1.5ns (min), 6.2ns (max) - ensures fast, deterministic bus arbitration and hot-swap readiness |
| tSK(o) | <0.5ns - guarantees simultaneous switching of grouped outputs for clean data capture |
| Input Hysteresis | 150mV - suppresses false triggering on slow-rising or EMI-contaminated control signals |
| ICC Quiescent | 0.1μA typ. - enables ultra-low static power in always-on monitoring subsystems |
Pinout & Package
74FCT163244APVG8 is housed in a 48-pin Thin Shrink Small Outline Package (TSSOP), RoHS-compliant and green-processed (PVG suffix). The package measures 12.5mm × 6.1mm × 1.2mm with 0.5mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE–4OE | Active-low 3-state enable inputs | Independent control per 4-bit group; enables partial bus isolation without full device disable |
| 1A1–4A4 | Data inputs | 16 total inputs tolerant of 5V logic; no external clamping required when driven by 5V sources |
| 1Y1–4Y4 | 3-state buffered outputs | Non-inverting outputs with rail-to-rail swing; sink/source up to ±60mA per pin |
| VCC (Pins 24, 48) | Power supply | Dual VCC pins minimize IR drop and improve PSRR across wide operating frequency range |
| GND (Pins 1, 12, 25, 36, 47) | Ground reference | Five GND pins provide low-inductance return paths for all output groups and reduce ground bounce |
Key Features
| Feature | Design Value |
|---|---|
| Mixed-voltage input compatibility | Accepts 3.3V or 5V logic inputs directly-eliminates need for discrete level translators in hybrid supply systems |
| Rail-to-rail output swing | VOH ≥ VCC–0.2V and VOL ≤ 0.2V at light load-maximizes noise margin in electrically noisy industrial environments |
| Low ground bounce | 0.3V typical-prevents logic corruption during simultaneous multi-bit switching on shared PCB planes |
| Flow-through pinout | Inputs and outputs arranged on opposite sides of package-reduces trace crossing and layer count in dense backplane layouts |
| Hysteresis-enhanced inputs | 150mV threshold hysteresis-rejects sub-microsecond noise spikes without external RC filtering |

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 |
|---|---|---|---|
| SN74ALVCH162244DGGR | Lower VCC range (1.65–3.6V); higher ICCZ (10μA max); no 5V-tolerant inputs | Requires external level shifting for 5V interfaces; better suited for pure 1.8V/3.3V systems | Select when operating exclusively below 3.3V and lowest static power is critical |
| 74LVC16244APAG | Same 48-pin TSSOP; 5V-tolerant inputs; but only ±24mA drive and 6.7ns max tPLH | Lower drive limits use in high-capacitance buses; slower timing restricts >80MHz operation | Select when cost sensitivity outweighs speed and drive requirements |
Compared with SN74ALVCH162244DGGR and 74LVC16244APAG, the 74FCT163244APVG8 uniquely combines 5V-tolerant inputs, ±60mA drive, sub-5ns propagation, and industrial temperature support-making it the only option among the three qualified for mixed-voltage, high-speed, high-noise industrial backplanes.

FAQ
What is the operating temperature range for the 74FCT163244APVG8?
The 74FCT163244APVG8 is rated for industrial temperature operation from –40°C to +85°C. This range is guaranteed across its full specified VCC range of 2.7V to 3.6V and applies to all DC and AC electrical characteristics, including propagation delay, output drive, and 3-state leakage. The device uses thermal design and process controls validated per MIL-STD-883 methods to ensure reliability under sustained thermal cycling in factory automation and outdoor control cabinet environments.
Does the 74FCT163244APVG8 support 5V input signals?
Yes, the 74FCT163244APVG8 accepts 5V logic-level inputs on all data (xAx) and enable (xOE) pins, even when VCC is 3.3V. This is confirmed by absolute maximum ratings specifying input terminal voltage up to +7V and DC electrical specs showing VIH up to 5.5V. No external clamping diodes or resistors are needed, making the 74FCT163244APVG8 ideal for translating between legacy 5V peripherals and modern 3.3V processors without added components.
What package type does the 74FCT163244APVG8 use?
The 74FCT163244APVG8 uses a 48-pin Thin Shrink Small Outline Package (TSSOP) with green/RoHS-compliant finish (PVG suffix). Its dimensions are 12.5mm × 6.1mm × 1.2mm with 0.5mm lead pitch. The package includes five ground pins and dual VCC pins to reduce impedance and improve signal integrity-critical for maintaining low ground bounce (<0.3V typ.) in high-speed bus applications.
How many independent 3-state control groups does the 74FCT163244APVG8 have?
The 74FCT163244APVG8 has four independent active-low 3-state enable inputs: 1OE, 2OE, 3OE, and 4OE. Each controls a separate 4-bit group (e.g., 1OE enables 1Y1–1Y4), enabling flexible bus segmentation, partial isolation, and dynamic power management. This architecture allows selective activation of bus segments without disabling the entire 16-bit path-essential for fault containment and hot-swap support in industrial backplanes.
What is the maximum output current rating per pin for the 74FCT163244APVG8?
The 74FCT163244APVG8 is rated for ±60mA DC output current per pin (IOUT = –60mA to +60mA), as specified in Absolute Maximum Ratings. Under standard operating conditions (VCC = 3.3V), it delivers –36mA (sourcing) and +50mA (sinking) at VO = 1.5V, with guaranteed minimums of –110mA sourcing and +200mA sinking under worst-case conditions. This drive strength supports direct interfacing to 50Ω transmission lines and fan-out to multiple CMOS or TTL loads without external buffers.
