Product details
Overview
74FCT162245ATPVG from Renesas Electronics (formerly IDT) is a 16-bit bidirectional transceiver in TSSOP-48 package, designed for synchronous bus interface between two 16-bit data paths. It supports industrial temperature range (–40°C to +85°C), features ±24mA balanced output drive, <4.6ns A↔B propagation delay (CL=50pF), and hysteresis-equipped inputs for noise immunity - used in backplane interconnects and memory-mapped I/O expansion.
For engineers reviewing the 74FCT162245ATPVG datasheet, 74FCT162245ATPVG pinout, 74FCT162245ATPVG application, or 74FCT162245ATPVG equivalent, key selection criteria include direction/output enable logic behavior, 5V supply compatibility, 3-state output timing (tPZH ≤ 4.4ns), and TSSOP-48 thermal and layout constraints for high-density PCBs.
Technical Context
The 74FCT162245ATPVG implements dual 8-bit or unified 16-bit bidirectional data transfer via independent DIR/OE controls per 8-bit half. Its dual-metal CMOS process enables low ground bounce (VOLP < 0.6V) and controlled fall times without external termination resistors.
Each port (A and B) comprises eight I/O pins with identical electrical characteristics: input hysteresis ≥100mV, input leakage ≤±1µA, and output drive rated at –24mA/24mA (IOH/IODL) under industrial conditions - ensuring robust signal integrity across noisy industrial bus environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5.0V ±10% - compatible with legacy TTL/CMOS 5V systems; no level-shifting required |
| tPLH / tPHL | ≤4.6ns (max) - ensures sub-5ns data path latency for high-speed synchronous bus bridging |
| Output Drive | ±24mA (industrial) - sufficient to drive 50Ω transmission lines or multiple TTL loads without buffers |
| Input Hysteresis | ≥100mV - rejects fast transient noise on control or data lines in electrically harsh environments |
| IOZL / IOZH | ≤±1µA - guarantees minimal leakage in 3-state disabled mode, critical for bus contention avoidance |
| tSK(o) | <0.5ns (typ) - minimizes skew-induced timing margin loss across all 16 bits during parallel transfers |
| Operating Temp | –40°C to +85°C - validated for industrial control, test equipment, and telecom line cards |
Pinout & Package
TSSOP-48 package (lead-free, green compliant), 0.5mm pitch, body width 6.1mm, height 1.2mm - optimized for automated SMT assembly and thermal dissipation in compact industrial modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction Control Input (Active HIGH) | Determines data flow direction per 8-bit segment: HIGH = A→B, LOW = B→A |
| 1OE, 2OE | Output Enable Input (Active LOW) | Disables both ports to high-impedance state when HIGH; overrides DIR control |
| 1A1–1A8, 2A1–2A8 | Port A I/O Pins | Bidirectional data terminals for first/second 8-bit bus segment; 3-state capable |
| 1B1–1B8, 2B1–2B8 | Port B I/O Pins | Bidirectional data terminals mirroring Port A; electrically matched for balanced signaling |
| VCC (Pins 11, 24, 37, 48) | Power Supply | Four dedicated VCC pins reduce IR drop and improve noise rejection across wide bus |
| GND (Pins 10, 23, 36, 47) | Ground Reference | Four GND pins minimize ground bounce and support clean return paths for 16-bit switching |
Key Features
| Feature | Design Value |
|---|---|
| Balanced Output Drivers | ±24mA drive strength with current-limiting resistors reduces ground bounce (VOLP < 0.6V) and eliminates need for series termination |
| Hysteresis-Enhanced Inputs | 100mV input hysteresis improves noise immunity on control lines in EMI-prone industrial enclosures |
| Low Skew Performance | 0.5ns max output skew ensures deterministic timing alignment across all 16 bits for synchronous protocols |
| Flexible Bus Configuration | Two independent 8-bit transceivers or one unified 16-bit unit - configurable via DIR/OE pin pairing |
| MIL-STD-883 Qualified | ESD >2000V (HBM), >200V (MM) - meets reliability requirements for mission-critical industrial deployments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ABT16245DGGR | Higher ICCZ (up to 1.5mA), no hysteresis, 500ps typical skew | Limited noise immunity in EMI-heavy environments; higher static power draw | Prefer 74FCT162245ATPVG where ground bounce or noise margin is critical |
| 74LVC16245APAG | 3.3V-only supply, lower drive (±24mA @ 3.3V), 1.8V–3.6V I/O tolerance | Not 5V-tolerant; requires level-shifting when interfacing with 5V buses | Select 74FCT162245ATPVG for native 5V system integration without voltage translation |
Compared with SN74ABT16245DGGR and 74LVC16245APAG, the 74FCT162245ATPVG delivers superior noise immunity (hysteresis), lower ground bounce, and guaranteed 5V operation - making it optimal for industrial bus bridging where signal integrity and legacy compatibility are non-negotiable.

FAQ
What is the operating voltage range for the 74FCT162245ATPVG?
The 74FCT162245ATPVG operates at 5.0V ±10%, i.e., 4.5V to 5.5V. This fixed 5V supply requirement ensures compatibility with legacy TTL and CMOS systems without level-shifting circuitry. The device does not support mixed-voltage or 3.3V operation - using voltages outside this range may cause functional failure or permanent damage.
Does the 74FCT162245ATPVG support hot-swap or live-insertion?
The 74FCT162245ATPVG is not explicitly rated for hot-swap operation. Its absolute maximum rating for terminal voltage is –0.5V to +7V, but no current-limiting or precharge features are specified. For live-insertion applications, external protection circuitry (e.g., series resistors, TVS diodes) and controlled power sequencing are required to prevent bus contention or latch-up during insertion.
How many independent transceiver sections does the 74FCT162245ATPVG contain?
The 74FCT162245ATPVG contains two independent 8-bit bidirectional transceiver sections - controlled by separate DIR/OE pairs (1DIR/1OE and 2DIR/2OE). This allows simultaneous or asynchronous data transfer across two 8-bit buses, or unified operation as a single 16-bit transceiver when both DIR/OE signals are tied together.
What is the maximum capacitive load the 74FCT162245ATPVG can drive reliably?
The 74FCT162245ATPVG is characterized for CL = 50pF in switching specifications, with typical output capacitance (COUT) ≤8pF. While it can drive heavier loads, timing parameters (e.g., tPLH, tPHL) degrade beyond 50pF - for reliable sub-5ns performance, keep total load (including trace and stub capacitance) ≤50pF per pin. External termination is unnecessary due to built-in current-limiting drivers.
Is the 74FCT162245ATPVG RoHS-compliant and lead-free?
Yes, the 74FCT162245ATPVG is RoHS-compliant and lead-free, as indicated by the "PVG" suffix (Thin Shrink Small Outline Package – Green). It meets JEDEC J-STD-609 Category 3 moisture sensitivity and complies with EU RoHS Directive 2011/65/EU and China RoHS II - verified through Renesas' official material declarations and packaging documentation.
