Product details
Overview
74FCT162244ATPVG from Renesas Electronics is a FAST CMOS 16-bit non-inverting buffer/line driver with independent 4-bit/8-bit/16-bit 3-state control, ±24mA balanced output drive (industrial), 4.1ns max propagation delay (CL = 50pF), and hysteresis-enhanced noise immunity-designed for high-speed bus interface and signal buffering in industrial backplanes and memory subsystems.
For engineers reviewing the 74FCT162244ATPVG datasheet, 74FCT162244ATPVG pinout, 74FCT162244ATPVG application, or 74FCT162244ATPVG equivalent, key selection criteria include output skew (<0.5ns), ground bounce (<0.6V), industrial temperature range (–40°C to +85°C), TSSOP-48 green package compatibility, and ABT16244 drop-in upgrade path.
Technical Context
This device implements four independent 4-bit buffered drivers with active-low 3-state enable inputs (1OE–4OE), each controlling its respective 4-bit output group (1Y1–1Y4, etc.). All inputs feature Schmitt-trigger hysteresis (100mV typ.) to reject noise on slow or noisy signal lines.
Output drivers are symmetrically balanced (±24mA at VCC = 5V, TA = 25°C) with integrated current-limiting resistors, enabling controlled edge rates, reduced undershoot, and minimal need for external termination-especially critical for unterminated loads ≤200pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5.0V ±10% - fixed single-rail operation compatible with legacy TTL and 5V CMOS systems |
| Propagation Delay | 4.1ns max (tPLH/tPHL, CL = 50pF) - enables >200MHz bus timing margins in synchronous interfaces |
| Output Skew | <0.5ns - ensures simultaneous switching across all 16 outputs, critical for parallel data integrity |
| Output Drive | ±24mA (industrial) - supports driving multiple TTL loads or moderate-capacitance traces without buffers |
| Input Hysteresis | 100mV typ. - rejects up to 100mV of input noise, improving reliability in electrically noisy industrial environments |
| Ground Bounce | <0.6V (VOLP, VCC = 5V, TA = 25°C) - minimizes supply rail disturbance during simultaneous output switching |
| Operating Temp | –40°C to +85°C - qualified for extended industrial deployment including factory automation and telecom infrastructure |
Pinout & Package
74FCT162244ATPVG is housed in a 48-pin Thin Shrink Small Outline Package (TSSOP), lead-free and RoHS-compliant (Green). Pin layout follows flow-through organization to simplify PCB routing and reduce crosstalk.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE–4OE | Active-Low 3-State Enable Inputs | Independently disable 4-bit output groups (1Yx, 2Yx, 3Yx, 4Yx); logic LOW enables outputs, HIGH places them in high-Z |
| 1A1–1A4, 2A1–2A4, 3A1–3A4, 4A1–4A4 | Non-Inverting Data Inputs | Four banks of 4 buffered inputs; each maps directly to corresponding output bank with no inversion |
| 1Y1–1Y4, 2Y1–2Y4, 3Y1–3Y4, 4Y1–4Y4 | 3-State Non-Inverting Outputs | 16 total outputs; each mirrors its input when enabled, enters high-impedance state when OE is HIGH |
| VCC (Pins 10, 23, 36, 47) | Power Supply | Four distributed VCC pins reduce power delivery impedance and improve decoupling effectiveness across the die |
| GND (Pins 11, 24, 37, 48) | Ground Reference | Four dedicated GND pins minimize ground bounce and support clean return paths for all 16 drivers |
Key Features
| Feature | Design Value |
|---|---|
| Flow-through pinout | Input and output pins arranged on opposite sides of package to enable straight-layer PCB trace routing and reduce stub length |
| Balanced ±24mA outputs | Matched sourcing/sinking capability eliminates asymmetry-induced timing jitter and improves signal integrity on bidirectional buses |
| Hysteresis on all inputs | 100mV typical threshold separation increases noise immunity without requiring external filtering components |
| Low ground bounce (<0.6V) | Reduces coupling into adjacent signals and power rails, lowering risk of false triggering in mixed-signal systems |
| Shrink packaging (TSSOP-48) | 30% smaller footprint than standard SOIC-48, supporting higher board density in space-constrained industrial modules |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit buffer/line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ABT16244DGGR | Higher ICCZ (up to 1.5mA vs. 0.5µA typ.), no input hysteresis, 5.2ns max tPD, ±64mA drive | Designed for higher-drive, lower-noise-margin systems; lacks hysteresis-based noise rejection | Select when absolute maximum drive strength is required and board-level noise filtering is already implemented |
| 74LVC16244APAG | 3.3V-only supply (1.65–3.6V), lower drive (±24mA @ 3.3V), 5.6ns max tPD, no hysteresis | Not 5V-tolerant; incompatible with legacy 5V buses unless level-shifted | Select only for new 3.3V-only designs where voltage translation is acceptable and 5V interoperability is unnecessary |
Compared with SN74ABT16244DGGR and 74LVC16244APAG, the 74FCT162244ATPVG uniquely combines 5V operation, hysteresis-enhanced noise immunity, ultra-low output skew, and industrial temperature qualification-making it optimal for retrofitting legacy 5V systems requiring improved signal integrity without layout changes.

FAQ
What is the operating temperature range for the 74FCT162244ATPVG?
The 74FCT162244ATPVG is rated for industrial temperature operation from –40°C to +85°C. This range is validated per the datasheet's DC and switching specifications, ensuring full functionality-including propagation delay, output drive, and noise immunity-across the entire span without derating. The "AT" suffix explicitly denotes the industrial-grade variant, distinct from military (54FCT) or commercial (74FCT-T) versions.
Does the 74FCT162244ATPVG support 3.3V logic inputs?
No, the 74FCT162244ATPVG is a 5V-only device with TTL-compatible input thresholds (VIH = 2.0V min, VIL = 0.8V max) and requires VCC = 5.0V ±10%. It does not support 3.3V-only signaling nor guarantee correct operation with 3.3V inputs without external level translation. Its inputs are not 5V-tolerant in a 3.3V-supply context-they are designed exclusively for 5V system integration.
How many independent 3-state control inputs does the 74FCT162244ATPVG have?
The 74FCT162244ATPVG has four independent active-low 3-state enable inputs: 1OE, 2OE, 3OE, and 4OE. Each controls a separate 4-bit output group (e.g., 1OE enables/disables outputs 1Y1–1Y4), allowing flexible partitioning-such as 4-bit nibble control, 8-bit byte control, or full 16-bit bus gating-without external logic.
What package type is used for the 74FCT162244ATPVG?
The 74FCT162244ATPVG uses a 48-pin Thin Shrink Small Outline Package (TSSOP) with green (lead-free/RoHS-compliant) finish, indicated by the "PVG" suffix in the part number. This package measures 12.5mm × 6.1mm × 1.2mm and features fine-pitch leads (0.5mm), optimized for high-density industrial PCB layouts.
Is the 74FCT162244ATPVG pin-compatible with the 74ABT16244?
Yes, the 74FCT162244ATPVG is a direct pin-compatible and functionally equivalent drop-in replacement for the 74ABT16244 in TSSOP-48 packages. Pin assignments, pinout order, and logic behavior-including 3-state control polarity and non-inverting transfer-are identical. No PCB redesign is needed when upgrading to achieve lower ground bounce, tighter output skew, and hysteresis-enhanced noise immunity.
