Product details
Overview
74FCT162244CTPVG8 from Renesas Electronics is a FAST CMOS 16-bit non-inverting buffer/line driver with balanced ±24mA output drive (industrial), 3.2ns max propagation delay (tPLH/tPHL), and flow-through pinout in 48-pin TSSOP package. It supports independent 4-bit/8-bit/16-bit 3-state control and is designed for high-speed bus interface applications in industrial temperature range (–40°C to +85°C).
For engineers reviewing the 74FCT162244CTPVG8 datasheet, 74FCT162244CTPVG8 pinout, 74FCT162244CTPVG8 application, or 74FCT162244CTPVG8 equivalent, key selection criteria include output skew (<0.5ns), ground bounce (<0.6V), hysteresis-enhanced noise margin, and RoHS-compliant green TSSOP packaging.
Technical Context
This device implements four independent 4-bit non-inverting buffers, each with dedicated active-low 3-state enable (xOE). All inputs feature hysteresis for noise immunity, and outputs incorporate current-limiting resistors to suppress ground bounce and undershoot.
It operates at 5.0V ±10%, delivers guaranteed VOL ≤ 0.55V at 24mA sink, VOH ≥ 2.4V at 24mA source, and maintains tSK(o) < 0.5ns across all outputs-critical for synchronous bus timing integrity in backplane and memory interface designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 5.0V ±10% - compatible with standard TTL/CMOS logic rails and eliminates level-shifting in 5V systems. |
| Propagation Delay | 3.2ns max (tPLH/tPHL, CL = 50pF) - enables >300MHz bus operation with tight timing margins. |
| Output Drive | ±24mA (industrial) - drives heavy capacitive loads (≤200pF) without external termination resistors. |
| Output Skew | <0.5ns - ensures simultaneous switching across all 16 outputs, minimizing data valid window degradation. |
| Input Hysteresis | 100mV typical - rejects high-frequency noise on address/data/control lines in electrically noisy industrial environments. |
| Quiescent Current | 500µA max (ICCL) - reduces static power in always-on bus buffering applications. |
| Package | 48-pin TSSOP (PVG) - 0.5mm pitch, RoHS-compliant green package optimized for automated SMT assembly and thermal dissipation. |
Pinout & Package
48-pin Thin Shrink Small Outline Package (TSSOP), lead-free and RoHS-compliant (PVG suffix). Flow-through pin arrangement minimizes PCB trace crossovers and simplifies routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE, 3OE, 4OE | Active-low 3-state enable inputs | Independently control 4-bit groups; asserted LOW enables corresponding Y outputs, HIGH places them in high-impedance state. |
| 1A1–1A4, 2A1–2A4, 3A1–3A4, 4A1–4A4 | Non-inverting data inputs | Accept TTL/CMOS-compatible logic levels; hysteresis improves noise rejection on long traces or unterminated stubs. |
| 1Y1–1Y4, 2Y1–2Y4, 3Y1–3Y4, 4Y1–4Y4 | Non-inverting 3-state outputs | Deliver balanced ±24mA drive with controlled fall times; low ground bounce (<0.6V) avoids false triggering in adjacent circuits. |
| VCC (Pins 10, 24, 37, 47) | Power supply | Four distributed VCC pins reduce power delivery impedance and improve decoupling effectiveness across the wide bus. |
| GND (Pins 9, 23, 36, 48, and others) | Ground reference | Five GND pins provide low-inductance return paths, critical for suppressing simultaneous switching noise (SSN). |
Key Features
| Feature | Design Value |
|---|---|
| Balanced ±24mA output drive | Eliminates need for external series termination on point-to-point or short-stub buses up to 200pF load. |
| Flow-through pinout | Input and output pins aligned on opposite sides of package, enabling straight PCB trace routing and reducing layer count. |
| Hysteresis on all inputs | 100mV typical threshold separation increases noise immunity by >2× versus standard CMOS inputs in industrial EMI environments. |
| Low output ground bounce (VOLP) | <0.6V at VCC = 5V - prevents false logic transitions in neighboring devices sharing common ground planes. |
| 0.5ns output skew (tSK(o)) | Guaranteed by design - preserves setup/hold timing margins across 16-bit parallel interfaces like memory data buses or FPGA I/O expansion. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74FCT162244CPAG | Same FCT family, identical AC/DC specs, but in 48-pin SSOP (PAG) instead of TSSOP (PVG); slightly larger footprint and higher thermal resistance. | Preferred where board rework tolerance or hand-soldering is required; less suitable for high-density automated assembly. | Select SN74FCT162244CPAG only if SSOP footprint compatibility is mandatory; PVG offers superior thermal performance and smaller area. |
| 74ABT162244CMTD | Higher ICC (up to 2.3mA vs. 0.5mA), no input hysteresis, and higher VOLP (>1.0V); otherwise pin-compatible and functionally identical. | Not recommended for EMI-prone industrial settings; acceptable in benign lab or office environments with clean power. | Choose 74ABT162244CMTD only when cost is primary constraint and noise immunity is non-critical; 74FCT162244CTPVG8 provides measurable reliability advantage. |
Compared with SN74FCT162244CPAG and 74ABT162244CMTD, the 74FCT162244CTPVG8 delivers lower ground bounce, built-in hysteresis, and RoHS-compliant TSSOP packaging-making it the optimal choice for new industrial designs requiring robust signal integrity and long-term supply stability.

FAQ
What is the operating temperature range for the 74FCT162244CTPVG8?
The 74FCT162244CTPVG8 is rated for industrial temperature operation from –40°C to +85°C. This range is explicitly defined in the datasheet's "DC Electrical Characteristics" section and applies to all guaranteed AC and DC parameters, including propagation delay, drive strength, and noise margin. The 'C' in the part number denotes the industrial grade, distinguishing it from military ('T') or extended commercial variants.
Does the 74FCT162244CTPVG8 support hot-swap or live-insertion?
The 74FCT162244CTPVG8 does not include explicit hot-swap protection circuitry such as power-up sequencing control or bus-fault isolation. Its absolute maximum ratings allow terminal voltages from –0.5V to VCC+0.5V, and it features high-impedance outputs when OE is HIGH-but it lacks current-limiting or slew-rate control during insertion transients. Use with external current-limiting resistors and controlled power sequencing is recommended for live-insertion scenarios.
What is the meaning of the 'PVG' suffix in 74FCT162244CTPVG8?
The 'PVG' suffix in 74FCT162244CTPVG8 indicates a 48-pin Thin Shrink Small Outline Package (TSSOP) with lead-free, RoHS-compliant green molding compound. 'PV' designates the TSSOP body style (6.1mm × 12.5mm), and 'G' confirms halogen-free, green-process compliance per JEDEC J-STD-609. This package replaces older SSOP variants for improved manufacturability and thermal performance.
Can the 74FCT162244CTPVG8 drive 50Ω transmission lines directly?
The 74FCT162244CTPVG8 is not designed for direct 50Ω point-to-point transmission line driving. Its ±24mA drive capability targets loads ≤200pF with controlled edge rates-not 50Ω characteristic impedance. For true 50Ω line driving, external series termination (typically 33Ω) is required at the source to match Zo and prevent reflections, as confirmed by the datasheet's "Reduced system switching noise" and "controlled output fall times" design intent.
How many independent 3-state control groups does the 74FCT162244CTPVG8 have?
The 74FCT162244CTPVG8 has four independent active-low 3-state enable inputs: 1OE, 2OE, 3OE, and 4OE. Each controls a distinct 4-bit output group (e.g., 1OE enables 1Y1–1Y4), allowing flexible partitioning into 4-bit, 8-bit, or full 16-bit configurations. This architecture is explicitly defined in the "PIN DESCRIPTION" and "FUNCTION TABLE" sections of the datasheet.
