Product details
Overview
PI74FCT162245ATV from Pericom Semiconductor is a 16-bit bidirectional transceiver in TVSOP-48 package, designed for asynchronous two-way data bus interfacing between dissimilar logic domains. It features ±24mA balanced output drivers, 0.6V typical ground bounce (VOLP), 5.0V ±10% supply operation, and hysteresis on all inputs-enabling robust noise immunity in industrial backplane and memory expansion applications.
For engineers reviewing the PI74FCT162245ATV datasheet, PI74FCT162245ATV pinout, PI74FCT162245ATV application, or PI74FCT162245ATV equivalent, key selection criteria include bidirectional flow control via xDIR/xOE, low-noise edge-rate limiting without external termination, and compatibility with 5V TTL/CMOS buses requiring high-current drive and bus stability.
Technical Context
This device implements dual 8-bit or unified 16-bit bidirectional data transfer using independent direction (xDIR) and 3-state enable (xOE) controls per port pair. Its CMOS-based FCT architecture delivers sub-7ns propagation delay (tPLH/tPHL) at 50pF load while maintaining TTL-compatible input thresholds (VIH = 2.0V, VIL = 0.8V).
The integrated current-limiting resistors at outputs suppress ground bounce and undershoot, enabling clean signal integrity in dense PCB layouts. All I/O pins support hot-plug–safe high-impedance states when xOE is HIGH, and operate across –40°C to +85°C ambient with 5V ±10% supply tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5.0V ±10% - ensures compatibility with legacy 5V TTL systems and stable operation under rail variation |
| Output Drive | ±24mA - provides sufficient current to drive multiple loads or long traces without external buffers |
| Ground Bounce (VOLP) | <0.6V typical - minimizes simultaneous switching noise, eliminating need for board-level decoupling tuning |
| Propagation Delay | 1.5–7.0ns - supports high-speed bus arbitration up to ~140MHz effective data rate in burst mode |
| Input Hysteresis | 100mV - rejects noise on slow-rising or unterminated bus lines, preventing metastability |
| Operating Temp | –40°C to +85°C - qualified for industrial-grade embedded control and telecom infrastructure |
| Input Capacitance | 4.5–6.0pF - reduces loading on upstream drivers, preserving signal rise/fall times |
Pinout & Package
PI74FCT162245ATV is housed in a 48-pin JEDEC-standard TVSOP (K48) package, 173 mil wide, with 0.4mm pitch and exposed thermal pad (non-electrical). Pin numbering follows standard counter-clockwise convention from index mark.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A0–1A7, 2A0–2A7 | Port A I/O | Side-A bidirectional data terminals; function as inputs or high-Z outputs depending on xDIR/xOE state |
| 1B0–1B7, 2B0–2B7 | Port B I/O | Side-B bidirectional data terminals; mirror A-side behavior with opposite directionality |
| 1DIR, 2DIR | Direction Control | Active-HIGH signal selecting A→B (HIGH) or B→A (LOW) data flow per 8-bit section |
| 1OE, 2OE | Output Enable | Active-LOW control placing corresponding A/B ports into high-impedance state when HIGH |
| VCC (Pins 24, 48) | Power Input | Dual VCC pins reduce IR drop and improve power delivery integrity across 16-bit bus |
| GND (Pins 1, 25) | Ground Reference | Dual GND pins minimize ground loop inductance and stabilize switching noise margins |
Key Features
| Feature | Design Value |
|---|---|
| Balanced ±24mA Output Drivers | Enables matched rise/fall times and symmetrical loading on both sides of the bus, reducing skew-induced timing errors |
| Integrated Edge-Rate Control | On-die current-limiting resistors eliminate need for external series termination, saving PCB area and BOM cost |
| Low Ground Bounce (<0.6V) | Prevents false logic transitions during high-frequency bus toggling, critical for reliable multi-drop backplane designs |
| Hysteresis on All Inputs | Provides 100mV noise margin against EMI and crosstalk in electrically noisy industrial environments |
| Hot-Insertion Support | Power-off disable capability allows safe insertion/removal of daughter cards without disrupting host system power rails |
Applications
| Industrial Backplane Interfacing | Memory Expansion Subsystem |
|---|---|
Use Scenario: Connecting CPU local bus to peripheral expansion slots in programmable logic controllers (PLCs) with mixed-voltage modules. IC Role / Device Role / Timing Role: Bidirectional level-shifting transceiver managing data flow between 5V control logic and 3.3V I/O modules via direction-controlled burst transfers. Use Value: ±24mA drive sustains signal integrity over 15cm backplane traces; low VOLP prevents latch-up in shared ground planes. | Use Scenario: Extending SRAM or Flash memory width in embedded instrumentation systems using dual-bank addressing. IC Role / Device Role / Timing Role: 16-bit data path extender enabling 32-bit word access across two parallel memory banks controlled by bank-select logic.

Use Scenario: Interfacing ISA or PCI-X legacy controllers to modern FPGA-based data acquisition front-ends in lab equipment. IC Role / Device Role / Timing Role: Asynchronous protocol translator buffering and direction-managing data between mismatched clock domains. Use Value: Dual OE/DIR controls allow dynamic reconfiguration of 8-bit segments during runtime, supporting variable-width packet framing. | Use Scenario: High-fidelity digital waveform capture where analog-to-digital converter outputs feed into real-time processing FPGA via parallel bus. IC Role / Device Role / Timing Role: Low-noise data conduit isolating sensitive ADC digital outputs from FPGA switching noise. Use Value: <0.6V VOLP ensures clean 16-bit sample alignment without post-capture error correction overhead. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit bidirectional transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74FCT162245CPAG | Same ±24mA drive, but SSOP-48 (V48) package; no TVSOP variant offered | Requires PCB redesign for wider 300-mil footprint; higher thermal resistance than TVSOP | Select if existing layout uses SSOP or requires higher creepage clearance |
| 74ALVC162245PW | 3.3V-only operation; 24mA drive; no hysteresis; 3.6V max VCC | Not suitable for 5V bus interfacing; lacks noise immunity for industrial EMI environments | Choose only for pure 3.3V systems where voltage translation is handled externally |
Compared with SN74FCT162245CPAG and 74ALVC162245PW, PI74FCT162245ATV uniquely combines 5V tolerance, hysteresis, ultra-low ground bounce, and TVSOP packaging-making it optimal for space-constrained, noise-sensitive industrial backplanes requiring legacy voltage compatibility.

FAQ
Does PI74FCT162245ATV support live insertion in powered backplanes?
Yes. Its power-off disable feature ensures outputs enter high-impedance state when VCC = 0V, allowing safe insertion into live 5V backplanes without short-circuit risk or system disruption. This is confirmed by the IOFF specification of ±100µA at VCC = 0V and VIN/VOUT ≤ 4.5V.
What is the maximum data rate supported by PI74FCT162245ATV in practical PCB layouts?
With 1.5–7.0ns propagation delay and <0.6V ground bounce, the device reliably supports sustained 100MHz burst transfers on well-designed 50Ω-controlled impedance traces up to 15cm. Real-world performance depends on trace length, termination, and load capacitance-not theoretical toggle rate.
Can PI74FCT162245ATV interface directly between 5V and 3.3V logic domains?
No. It operates exclusively at 5.0V ±10% and has TTL-compatible input thresholds (VIH = 2.0V, VIL = 0.8V), making it safe for 3.3V outputs driving its inputs-but not for 3.3V systems sourcing >3.6V. Level translation requires external circuitry for bidirectional 3.3V↔5V interfacing.
Is the TVSOP-48 package (K48) thermally adequate for continuous 16-bit toggling at 25°C ambient?
Yes. At full 16-bit toggling (fI = 2.5MHz), total supply current is ≤5.5mA, yielding <28mW dissipation. The K48 package's θJA ≈ 120°C/W keeps junction temperature below 60°C-well within the 150°C absolute max-without heatsinking under standard airflow conditions.
