Product details
Overview
74FCT162245ATPVG8 from Renesas Electronics (formerly IDT) is a FAST CMOS 16-bit bidirectional transceiver with balanced ±24mA industrial drive, hysteresis-enhanced noise immunity, and dual 8-bit/16-bit configurable operation for synchronous bus interfacing between A- and B-side data paths. It operates at 5.0V ±10% across –40°C to +85°C and supports plug-in replacement of FCT16245T in board-level interface applications.
For engineers reviewing the 74FCT162245ATPVG8 datasheet, 74FCT162245ATPVG8 pinout, 74FCT162245ATPVG8 application, or 74FCT162245ATPVG8 equivalent, key selection criteria include output skew < 0.5ns, tPLH/tPHL ≤ 4.6ns (industrial), 3.5pF input capacitance, ±24mA drive capability, and SSOP-48 green package compliance.
Technical Context
This device implements two independent 8-bit transceivers or one unified 16-bit transceiver via dedicated xDIR (direction control) and xOE (output enable, active-low) pins per side. All I/Os feature hysteresis on inputs and current-limiting resistors on outputs to suppress ground bounce (< 0.6V typical) and undershoot.
It uses 0.5µm CMOS technology with TTL-compatible input thresholds (VIH = 2.0V min, VIL = 0.8V max), supports 50pF load switching, and guarantees output skew ≤ 0.5ns across all outputs within the same package under identical switching conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5.0V ±10% - fixed single-rail operation; no internal regulation or multi-voltage support |
| tPLH / tPHL | ≤ 4.6ns (industrial) - ensures sub-5ns propagation delay for high-speed synchronous bus handshaking |
| IODL / IODH | ±24mA (industrial) - enables direct driving of 50Ω transmission lines without external series termination |
| CIN / COUT | 3.5pF / 3.5pF typ - low capacitive loading preserves signal integrity on dense PCB layouts |
| tSK(o) | < 0.5ns - tightly controlled output timing alignment critical for parallel data capture across 16 bits |
| VOLP | < 0.6V @ 5V, 25°C - minimizes ground bounce-induced logic errors during simultaneous switching |
| VIH / VIL | 2.0V min / 0.8V max - full TTL-level compatibility with legacy 5V logic families |
Pinout & Package
74FCT162245ATPVG8 is housed in a 48-pin Shrink Small Outline Package (SSOP), Green (Pb-free), with 0.5mm pitch and exposed pad not present. Pin numbering follows standard SSOP top-view convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input (active-HIGH) | Determines data flow direction per 8-bit bank: HIGH = A→B, LOW = B→A |
| 1OE, 2OE | Output enable input (active-LOW) | Overrides DIR; LOW enables transceiver, HIGH forces both ports into high-Z |
| 1A1–1A8, 2A1–2A8 | Side-A I/O terminals | Bi-directional data path for first/second 8-bit bus segment; 3-state when OE HIGH |
| 1B1–1B8, 2B1–2B8 | Side-B I/O terminals | Bi-directional data path for complementary 8-bit bus segment; 3-state when OE HIGH |
| VCC (pins 11, 24, 37, 48) | Power supply | Four distributed VCC pins reduce IR drop and improve noise rejection across wide bus |
| GND (pins 12, 23, 25, 36, 47) | Ground reference | Five GND pins provide low-inductance return paths for high-speed switching currents |
Key Features
| Feature | Design Value |
|---|---|
| Balanced ±24mA output drive | Enables impedance-matched 50Ω line driving without external series resistors, reducing BOM count and layout area |
| Hysteresis on all inputs | 100mV typical hysteresis improves noise margin against EMI and crosstalk in industrial environments |
| Low ground bounce (VOLP < 0.6V) | Minimizes false triggering in adjacent logic due to simultaneous switching noise on shared ground planes |
| 0.5ns max output skew | Ensures deterministic setup/hold timing for 16-bit parallel data capture at >200MHz effective bus rates |
| Plug-in replacement for FCT16245T | Same pinout and electrical behavior allows drop-in upgrade path without PCB revision |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74FCT162245ATPV | Same function, pinout, and specs; Texas Instruments rebrand of original IDT part; identical SSOP-48 packaging and timing | No functional deviation; fully interchangeable in existing designs using TI-sourced components | Select when sourcing from TI distribution channels or requiring TI-specific documentation and support |
| 74ABT162245CMTD | Higher drive (±32mA), faster tPLH/tPHL (≤3.5ns), but no hysteresis and higher ICCZ (500µA vs 5µA quiescent) | Better for ultra-high-speed, low-noise systems where power budget allows; less tolerant of marginal signal integrity | Prefer when maximum speed and drive strength outweigh noise margin and static power requirements |
Compared with SN74FCT162245ATPV, 74FCT162245ATPVG8 offers identical functionality and footprint but originates from Renesas' post-IDT portfolio with updated lifecycle management; versus 74ABT162245CMTD, it trades raw speed for superior noise immunity and lower static power-critical for thermally constrained industrial deployments.

FAQ
What is the operating temperature range for the 74FCT162245ATPVG8?
The 74FCT162245ATPVG8 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 specified timing and drive parameters under 5.0V ±10% supply conditions. It does not support military-grade –55°C to +125°C operation, which is reserved for the 54FCT162245T variant in CERPACK packaging.
Does the 74FCT162245ATPVG8 support true bidirectional data flow on each pin pair?
Yes, the 74FCT162245ATPVG8 supports true bidirectional operation: each A/B pin pair (e.g., 1A1 ↔ 1B1) functions as a reversible I/O path controlled by the corresponding xDIR and xOE signals. Direction is set per 8-bit bank (1DIR/2DIR), and both banks enter high-impedance state simultaneously when xOE is HIGH-enabling clean bus arbitration without contention.
What is the maximum guaranteed output skew for the 74FCT162245ATPVG8?
The 74FCT162245ATPVG8 guarantees output skew (tSK(o)) ≤ 0.5ns across any two outputs switching in the same direction within the same package. This value is design-guaranteed (not tested per unit) and applies under standard 5V/25°C conditions with CL = 50pF, ensuring deterministic timing for parallel data capture in synchronous systems.
Can the 74FCT162245ATPVG8 replace the 74FCT16245T without PCB changes?
Yes, the 74FCT162245ATPVG8 is documented as a plug-in replacement for the 74FCT16245T in on-board interface applications. Both share identical pinout, electrical specifications, and SSOP-48 packaging-confirmed in the datasheet's "Description" section-allowing direct substitution without layout modification or firmware adjustment.
What package type and RoHS status does the 74FCT162245ATPVG8 use?
The 74FCT162245ATPVG8 uses a 48-pin Shrink Small Outline Package (SSOP) with green (Pb-free) finish, indicated by the "PVG" suffix in the part number. It complies with RoHS Directive 2011/65/EU, as confirmed in the ordering information table and Renesas' product change notices dated September 2009 onward.
