Product details
Overview
74FCT163245CPAG8 from Renesas Electronics is a 3.3V CMOS 16-bit bidirectional transceiver with dual 8-bit operation mode, 4.1 ns max propagation delay (A→B/B→A), ±60 mA output drive, and industrial temperature range (–40°C to +85°C). It enables asynchronous bus interfacing between 3.3V and 5V systems in memory expansion and FPGA I/O bridging applications.
For engineers reviewing the 74FCT163245CPAG8 datasheet, 74FCT163245CPAG8 pinout, 74FCT163245CPAG8 application, or 74FCT163245CPAG8 equivalent, key selection criteria include bidirectional direction control (xDIR), active-low output enable (xOE), rail-to-rail output swing, low ground bounce (0.3 V typ.), and compatibility with TTL-level inputs.
Technical Context
The 74FCT163245CPAG8 implements two independent 8-bit transceiver sections (1A/1B and 2A/2B) controlled by separate xDIR and xOE pins per section. Its dual-metal CMOS process delivers 0.5 µm feature size and <250 ps output skew across outputs within the same package.
It supports mixed-voltage operation: inputs accept 3.3V or 5V logic levels, while outputs swing rail-to-rail (VOH ≥ 2.4 V at IOH = –8 mA, VOL ≤ 0.4 V at IOL = 24 mA), and operates across VCC = 2.7 V to 3.6 V with 0.4 µW typical static power consumption.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7 V to 3.6 V - supports extended supply tolerance for industrial power rails |
| Propagation Delay (tPLH/tPHL) | Max 4.1 ns (FCT163245C) - enables >200 MHz bus timing margin in high-speed data paths |
| Output Drive | ±60 mA - sufficient to drive 50 Ω transmission lines or multiple CMOS/TTL loads |
| Input Hysteresis | 150 mV - improves noise immunity on shared or noisy bus environments |
| ESD Rating | >2000 V (MIL-STD-883, Method 3015) - robust handling during board assembly and field service |
| Quiescent Current | 10 µA max - negligible standby power impact in always-on embedded systems |
Pinout & Package
74FCT163245CPAG8 is housed in a 48-pin TSSOP (Thin Shrink Small Outline Package) with 0.5 mm pitch, JEDEC MO-153 compliant, body dimensions 12.5 mm × 6.1 mm × 1.2 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction Control Input (Active HIGH) | Determines data flow direction per 8-bit section: LOW = B→A, HIGH = A→B |
| 1OE, 2OE | Output Enable Input (Active LOW) | Disables both ports to high-impedance state when HIGH; overrides DIR control |
| 1A1–1A8, 2A1–2A8 | Side A I/O Terminals | Bidirectional data interface for Bus A; tolerate 5V inputs while operating at 3.3V VCC |
| 1B1–1B8, 2B1–2B8 | Side B I/O Terminals | Bidirectional data interface for Bus B; identical electrical behavior to Side A |
| VCC (Pins 24, 36, 40, 48) | Power Supply | Four dedicated VCC pins reduce supply impedance and improve switching noise rejection |
| GND (Pins 13, 25, 26, 39) | Ground Reference | Four GND pins provide low-inductance return path for high-speed switching currents |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Ensures full logic swing (VOH ≥ 2.4 V, VOL ≤ 0.4 V) for maximum noise margin in mixed-voltage systems |
| Low ground bounce (0.3 V typ.) | Mitigates simultaneous switching noise that could corrupt adjacent signal integrity or cause false logic transitions |
| TTL-compatible inputs | Accepts 5 V logic levels on all inputs except I/O pins - simplifies interface to legacy 5 V controllers or FPGAs |
| 0.5 µm CMOS process | Enables high-speed operation with low static power (0.4 µW typ.) and improved thermal stability over temperature |
| Hysteresis on all inputs | 150 mV input hysteresis suppresses oscillation on slow-rising or noisy control signals like xOE/xDIR |
Applications
| Memory Expansion Interface | FPGA I/O Bridging |
|---|---|
|
Use Scenario: Interfacing a 3.3 V microcontroller bus to a 5 V SRAM or Flash memory subsystem. IC Role / Device Role / Timing Role: Bidirectional level-shifting transceiver managing address/data/control transfer between mismatched voltage domains. Use Value: Eliminates need for discrete level shifters; 4.1 ns propagation delay preserves setup/hold timing margins for 25+ MHz memory access. |
Use Scenario: Connecting a 3.3 V FPGA I/O bank to an external 5 V peripheral (e.g., ADC, DAC, or display controller). IC Role / Device Role / Timing Role: Direction-controlled data conduit enabling configurable read/write handshaking without external logic. Use Value: Dual 8-bit sections allow independent control of data and control buses; rail-to-rail outputs ensure reliable 5 V logic recognition. |
| Industrial Backplane Bus | Test Equipment Signal Routing |
|
Use Scenario: Isolating and routing parallel control/data signals across modular PLC backplane slots operating at different supply voltages. IC Role / Device Role / Timing Role: Hot-swap-capable bus transceiver with high ESD rating (>2000 V) and industrial temperature support. Use Value: Four VCC/GND pins minimize ground bounce during multi-bit switching; 0.3 V typical bounce ensures signal integrity in noisy factory environments. |
Use Scenario: Reconfigurable signal path selection in automated test equipment (ATE) where DUT I/O voltage levels vary between 3.3 V and 5 V. IC Role / Device Role / Timing Role: Programmable bidirectional switch enabling dynamic test vector routing under microcontroller control. Use Value: Independent xOE/xDIR per 8-bit section allows granular enable/disable - critical for fault isolation and test repeatability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVCH163245A | Lower drive strength (±24 mA), wider VCC range (1.65–3.6 V), no 5 V-tolerant inputs | Suitable for ultra-low-power 1.8 V/3.3 V only systems; not compatible with 5 V input sources | Select when interfacing exclusively with LVCMOS logic and minimizing supply current is critical |
| 74ALVC163245 | Higher speed (tPD = 3.2 ns typ.), same 5 V-tolerant inputs, but lower ESD rating (200 V machine model) | Better suited for high-frequency digital test fixtures where speed outweighs ESD robustness | Select when propagation delay is primary constraint and board-level ESD protection is already implemented |
Compared with SN74LVCH163245A and 74ALVC163245, the 74FCT163245CPAG8 uniquely balances 5 V-tolerant inputs, ±60 mA drive, industrial temperature range, and >2000 V ESD protection - making it optimal for ruggedized mixed-voltage industrial interfaces where reliability and compatibility are co-prioritized.

FAQ
What is the maximum operating frequency supported by the 74FCT163245CPAG8?
The 74FCT163245CPAG8 does not specify a clock frequency since it is an asynchronous transceiver. Its 4.1 ns maximum propagation delay enables reliable operation in data buses running up to approximately 200 MHz (based on round-trip timing budget). System-level frequency limits depend on PCB layout, load capacitance, and termination - not an internal clock.
Does the 74FCT163245CPAG8 support 5 V inputs while powered at 3.3 V?
Yes, the 74FCT163245CPAG8 accepts 5 V logic-level inputs on all control (xDIR, xOE) and I/O (A/B) pins while operating at VCC = 3.3 V. This is explicitly guaranteed in the datasheet's DC electrical characteristics, with VIH up to 5.5 V on input pins and VCC+0.5 V on I/O pins.
What is the function of the four VCC and four GND pins on the 74FCT163245CPAG8?
The 74FCT163245CPAG8 uses four VCC (pins 24, 36, 40, 48) and four GND (pins 13, 25, 26, 39) pins to reduce power distribution impedance and minimize simultaneous switching noise. This layout lowers ground bounce (0.3 V typ.) and improves signal integrity during high-speed, multi-bit transitions - critical for stable 16-bit bus operation.
Can the 74FCT163245CPAG8 be used as two independent 8-bit transceivers?
Yes, the 74FCT163245CPAG8 is internally partitioned into two independent 8-bit sections (1A/1B and 2A/2B), each with dedicated xDIR and xOE pins. This allows independent direction control and output enable - for example, transferring data from Bus A to Bus B on Section 1 while holding Section 2 in high-impedance state.
Is the 74FCT163245CPAG8 RoHS compliant and lead-free?
Yes, the "PAG" suffix in 74FCT163245CPAG8 denotes Thin Shrink Small Outline Package – Green, confirming RoHS compliance and lead-free construction per Renesas' ordering information. The device meets JEDEC J-STD-020 moisture sensitivity level 3 and is qualified for reflow soldering per IPC/JEDEC J-STD-020.
