Product details
Overview
74FCT162244CTPVG from Renesas Electronics is a 16-bit non-inverting 3-state buffer/line driver in TSSOP-48 package, designed for high-speed bus interface and signal buffering in industrial systems. It delivers ±24mA balanced output drive at 5V, typical propagation delay of 4.1ns (CL=50pF), and input hysteresis for noise immunity. Used in backplane drivers and memory address buffers where low ground bounce (<0.6V) and controlled fall times are critical.
For engineers reviewing the 74FCT162244CTPVG datasheet, 74FCT162244CTPVG pinout, 74FCT162244CTPVG application, or 74FCT162244CTPVG equivalent, key selection criteria include industrial temperature range (–40°C to +85°C), flow-through pinout for PCB layout simplification, 3.5pF input capacitance, and independent 4-/8-/16-bit 3-state control via four OE inputs.
Technical Context
This device implements a CMOS-based 16-bit buffer with four independent 4-bit sections, each controlled by its own active-low 3-state enable (1OE–4OE). Each section features hysteresis on all inputs and current-limiting output drivers to suppress ground bounce and undershoot.
It operates strictly at 5.0V ±10%, supports TTL-compatible inputs (VIH = 2.0V min, VIL = 0.8V max), and guarantees output skew <0.5ns across same-package outputs-critical for synchronous data capture in parallel bus architectures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5.0V ±10% - fixed single-rail operation; no dual-supply or level-shifting capability |
| Propagation Delay | 4.1ns max (tPLH/tPHL, CL=50pF) - enables >200MHz bus timing margin in point-to-point loads |
| Output Drive | ±24mA (industrial) - sufficient to drive 50Ω transmission lines or multiple TTL loads without external termination |
| Input Capacitance | 3.5pF typ - minimizes loading on upstream drivers and preserves signal integrity at high frequencies |
| Output Skew | <0.5ns - ensures simultaneous valid data arrival across all 16 bits for reliable latch capture |
| Operating Temp | –40°C to +85°C - qualified for extended industrial environments including factory automation and telecom infrastructure |
| Ground Bounce | <0.6V typ (VOLP, VCC=5V) - reduces false switching in adjacent logic due to simultaneous output transitions |
Pinout & Package
TSSOP-48 (4.4mm width), lead-free and RoHS-compliant green package with flow-through pin arrangement-inputs on one side, outputs on opposite side, enabling straight PCB trace routing and minimizing crosstalk.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE–4OE | Active-low 3-state enable inputs | Independent control per 4-bit group; assertion disables corresponding Y outputs to high-impedance |
| 1A1–4A4 | Buffer input terminals (16 total) | CMOS/TTL-compatible inputs with hysteresis; accept VIH ≥2.0V, VIL ≤0.8V |
| 1Y1–4Y4 | Non-inverting 3-state outputs (16 total) | Current-limited drivers with ±24mA capability; low VOLP/VOLH improves noise margin |
| VCC, GND | Power supply pins (multiple) | Four VCC and five GND pins distributed across package to reduce power/ground impedance and EMI |
Key Features
| Feature | Design Value |
|---|---|
| Flow-through pinout | Input and output pins arranged on opposite sides of TSSOP-48 package to eliminate layer jumps and stubs in high-speed routing |
| Balanced ±24mA drive | Matched sourcing/sinking capability eliminates DC bias on shared bus lines and reduces return path noise |
| Hysteresis on all inputs | 100mV typical hysteresis width increases noise immunity against slow-edge or noisy signals in industrial environments |
| Low ground bounce (<0.6V) | On-chip current limiting and optimized output stage minimize simultaneous switching output (SSO) effects on shared VCC/GND planes |
| Independent 4-bit 3-state control | Four separate OE pins allow partial bus isolation-e.g., disable only address bits while keeping data lines active |
Applications
| Memory Address Buffering | Backplane Signal Conditioning |
|---|---|
Use Scenario: Driving 16-bit address buses between microcontroller and SRAM/Flash in industrial PLCs. IC Role / Device Role / Timing Role: Non-inverting buffer with 3-state control synchronizes with memory access strobes to isolate bus during refresh cycles. Use Value: 4.1ns propagation delay and <0.5ns output skew ensure setup/hold compliance across full address width at 25MHz clock rates. | Use Scenario: Re-timing and strengthening parallel control signals across 100mm+ backplane traces in modular test equipment. IC Role / Device Role / Timing Role: Line driver compensating for capacitive loading (>150pF) and maintaining signal integrity over FR4 interconnect. Use Value: ±24mA drive and controlled fall times eliminate need for external series terminators while sustaining edge rates >1V/ns. |
| Industrial I/O Expansion | Legacy Bus Interface Adapter |
Use Scenario: Interfacing FPGA GPIO banks to 16-bit industrial I/O modules (e.g., relay banks, analog input muxes). IC Role / Device Role / Timing Role: Level-translating buffer (TTL-compatible inputs, CMOS outputs) with independent 4-bit enables for grouped I/O control. Use Value: Hysteresis and low leakage (≤1µA) prevent spurious toggling in electrically noisy factory floor environments. | Use Scenario: Adapting legacy ISA or VME bus signals to modern controller interfaces requiring clean, slew-controlled outputs. IC Role / Device Role / Timing Role: Signal repeater isolating noise-sensitive host logic from high-capacitance bus segments. Use Value: Low ground bounce (<0.6V) prevents corruption of adjacent data/control lines sharing common ground return paths. |
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 electrical specs, but in SSOP-48 package (wider 5.3mm body) | Requires PCB footprint change; no flow-through advantage; slightly higher thermal resistance | Select when SSOP-48 is already standardized in design and TSSOP height constraint is not critical |
| 74LVCH162244APAG | Lower voltage (1.65–3.6V), higher speed (2.9ns typ), but only ±24mA at 3.3V; no hysteresis | Not suitable for 5V TTL buses; requires level-shifting if interfacing with legacy 5V logic | Choose only for new 3.3V-only systems needing lower power and higher frequency; not drop-in for 5V designs |
Compared with SN74FCT162244CPAG and 74LVCH162244APAG, the 74FCT162244CTPVG uniquely combines 5V TTL compatibility, hysteresis-enhanced noise immunity, flow-through TSSOP-48 layout, and guaranteed <0.5ns output skew-making it optimal for industrial bus buffering where signal fidelity and layout simplicity are co-prioritized.

FAQ
What is the operating voltage range for the 74FCT162244CTPVG?
The 74FCT162244CTPVG operates exclusively at VCC = 5.0V ±10% (4.5V to 5.5V). It is not rated for 3.3V or mixed-voltage operation. All DC and AC specifications-including propagation delay, drive strength, and noise margins-are guaranteed only within this range, per the official Renesas datasheet revision dated September 2009.
Does the 74FCT162244CTPVG support hot-swap or live-insertion?
No, the 74FCT162244CTPVG does not support hot-swap. Its absolute maximum ratings specify terminal voltage limits of –0.5V to +7V (non-I/O pins) and –0.5V to VCC+0.5V (I/O pins), with no built-in power-up sequencing or bus-hold circuitry. Applying signal voltages before VCC stabilization may exceed clamp diode limits and risk damage.
How many independent 3-state control groups does the 74FCT162244CTPVG have?
The 74FCT162244CTPVG has four independent active-low 3-state enable inputs: 1OE, 2OE, 3OE, and 4OE. Each controls a dedicated 4-bit segment (e.g., 1OE enables/disables outputs 1Y1–1Y4), allowing flexible partial bus gating without affecting other sections-critical for multi-master arbitration or segmented memory mapping.
Is the 74FCT162244CTPVG pin-compatible with the 74ABT16244?
Yes-the 74FCT162244CTPVG is a pin-compatible, functionally equivalent replacement for the 74ABT16244 in TSSOP-48 packaging. Both share identical pinout, logic behavior, and 16-bit non-inverting 3-state architecture. The 74FCT162244CTPVG improves upon it with lower ground bounce, tighter output skew, and hysteresis on inputs.
What is the maximum capacitive load the 74FCT162244CTPVG can drive reliably?
The 74FCT162244CTPVG is characterized and specified for loads up to 200pF, as confirmed by its switching characteristics test conditions (CL = 50pF) and design intent stated in the datasheet: "reducing the need for external series terminating resistors while still providing very high speed operation for loads of less than 200pF." Beyond 200pF, propagation delay and waveform fidelity degrade beyond guaranteed limits.
