Product details
Overview
74FCT16245CTPVG8 from Renesas Electronics (formerly IDT) is a 16-bit bidirectional CMOS transceiver with dual 8-bit or unified 16-bit operation, ±32mA/64mA drive strength, <4.1ns propagation delay (CL=50pF), and industrial temperature range (–40°C to +85°C). It enables synchronous bus-to-bus communication in backplane and high-capacitance load applications.
For engineers reviewing the 74FCT16245CTPVG8 datasheet, 74FCT16245CTPVG8 pinout, 74FCT16245CTPVG8 application, or 74FCT16245CTPVG8 equivalent, key selection criteria include direction/output enable control logic, live-insertion support via power-off disable, TTL-compatible input thresholds, and SSOP-48 package compatibility with 5V systems.
Technical Context
The 74FCT16245CTPVG8 implements two independent 8-bit transceiver blocks controlled by dedicated DIR/OE pins per side, supporting asymmetric data flow (A→B or B→A) or high-impedance isolation. Its dual-metal CMOS process delivers low ground bounce (<1.0V VOLP) and tight output skew (<0.5ns tSK(o)).
All inputs feature hysteresis for noise immunity; outputs are designed for hot-swap capability with power-off disable, enabling safe board insertion into live 5V backplanes. The device operates strictly at VCC = 5.0V ±10% with guaranteed VIH ≥2.0V and VIL ≤0.8V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5.0V ±10% - fixed single-rail operation; no dual-supply or level-shifting capability |
| tPLH/tPHL | ≤4.1ns max (CL=50pF, RL=500Ω) - ensures sub-5ns timing margin for 100MHz+ synchronous bus interfaces |
| IOH/IOL Drive | –32mA / +64mA - drives heavy capacitive loads (e.g., >100pF traces) and low-impedance backplanes without external buffers |
| tSK(o) | <0.5ns - guarantees simultaneous switching across all 16 outputs, critical for parallel bus integrity |
| VIH/VIL | ≥2.0V / ≤0.8V - fully compatible with TTL logic families and legacy 5V microcontrollers |
| Power-off Disable | IOFF ≤ ±1μA at VCC = 0V - enables live insertion without bus contention or damage to powered system |
| Operating Temp | –40°C to +85°C - qualified for industrial environments including factory automation and telecom infrastructure |
Pinout & Package
74FCT16245CTPVG8 is packaged in a 48-pin Shrink Small Outline Package (SSOP), green RoHS-compliant, with 0.5mm pitch and exposed thermal pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction Control Inputs (Active HIGH) | Set data flow direction per 8-bit bank: HIGH = A→B, LOW = B→A |
| 1OE, 2OE | Output Enable Inputs (Active LOW) | Disable both ports to high-impedance state regardless of DIR setting |
| 1A1–1A8, 2A1–2A8 | Side-A I/O Terminals | Bi-directional data lines for first/second 8-bit bus segment; 3-state when OE active |
| 1B1–1B8, 2B1–2B8 | Side-B I/O Terminals | Bi-directional data lines for second/first 8-bit bus segment; mirror function to Side-A |
| VCC (Pins 11, 24, 37, 48) | Power Supply | Four dedicated VCC pins reduce IR drop and improve noise immunity across wide SSOP body |
| GND (Pins 10, 23, 36, 47) | Ground | Four GND pins provide low-inductance return paths for high-speed switching currents |
Key Features
| Feature | Design Value |
|---|---|
| Live Insertion Support | Power-off disable (IOFF ≤ ±1μA) prevents backfeeding and bus contention during hot-swap into live 5V backplanes |
| TTL-Compatible Inputs | Hysteresis-enhanced VIH/VIL (2.0V/0.8V) ensures robust noise margin in electrically noisy industrial enclosures |
| High-Drive Outputs | –32mA IOH / +64mA IOL enables direct driving of unterminated 50Ω traces or multi-drop buses without line drivers |
| Low Ground Bounce | VOLP < 1.0V at VCC = 5V eliminates false logic transitions caused by simultaneous output switching |
| Ultra-Low Skew | tSK(o) < 0.5ns maintains timing alignment across all 16 bits-essential for parallel address/data bus integrity |
Applications
| Industrial Backplane Interface | Legacy System Bus Extension |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74FCT16245CPAG | Same FCT family, identical electrical specs, but in 48-pin TSSOP (PAG) instead of SSOP (PVG); slightly different thermal pad layout | No change in functional use; TSSOP offers better thermal dissipation but requires PCB footprint update | Select SN74FCT16245CPAG only if TSSOP footprint is already standardized in your design and thermal performance is prioritized over legacy SSOP compatibility |
| 74LVCH16245APAG | Lower voltage (1.65–3.6V), higher speed (tPD ≤2.9ns), but incompatible 5V operation; no power-off disable | Not suitable for 5V backplanes; requires level translation and cannot support live insertion | Choose 74LVCH16245APAG only for new 3.3V-only systems where ultra-low latency and lower power outweigh 5V interoperability needs |
Compared with SN74FCT16245CPAG and 74LVCH16245APAG, the 74FCT16245CTPVG8 uniquely combines 5V tolerance, live-insertion capability, and industrial temperature rating-making it irreplaceable in legacy-maintenance and ruggedized backplane designs.

FAQ
What is the operating voltage range for the 74FCT16245CTPVG8?
The 74FCT16245CTPVG8 operates exclusively at VCC = 5.0V ±10% (4.5V to 5.5V). It is not rated for 3.3V or mixed-voltage operation. This fixed 5V requirement ensures compatibility with legacy TTL and CMOS systems while maintaining specified drive strength and timing performance. All DC and switching characteristics in the datasheet assume this supply range.
Does the 74FCT16245CTPVG8 support live insertion into a powered backplane?
Yes, the 74FCT16245CTPVG8 supports live insertion due to its power-off disable feature: when VCC = 0V, input/output leakage is limited to ±1μA (IOFF), preventing bus contention or damage to powered circuitry. This behavior is explicitly characterized and guaranteed across the industrial temperature range, making it suitable for hot-pluggable module designs.
How many independent transceiver sections does the 74FCT16245CTPVG8 contain?
The 74FCT16245CTPVG8 contains two independent 8-bit transceiver sections (labeled Side 1 and Side 2), each with dedicated DIR and OE controls. This architecture allows asymmetric operation-for example, enabling A→B flow on Side 1 while holding Side 2 in high-impedance-providing flexible bus partitioning without external logic.
What is the maximum capacitive load the 74FCT16245CTPVG8 can drive reliably?
The 74FCT16245CTPVG8 is characterized for CL = 50pF in switching tests, but its +64mA IOL and –32mA IOH ratings allow reliable driving of loads exceeding 100pF in real-world layouts. Performance depends on trace impedance and termination; for >75pF loads, maintain short stub lengths and avoid unterminated multi-drop topologies to preserve signal integrity.
Is the 74FCT16245CTPVG8 pin-compatible with other members of the FCT16245 family?
Yes, all FCT16245 variants-including 74FCT16245ATPVG8, 74FCT16245ETPVG8, and 54FCT16245T-share identical pinouts and package dimensions in SSOP-48. Differences lie only in speed grade (tPD), temperature range, and screening level-not in connectivity or mechanical fit-enabling drop-in replacement within the same package variant.
