Product details
Overview
PI74FCT16245ATV from Pericom Semiconductor is a 16-bit bidirectional transceiver IC designed for asynchronous two-way data bus communication in high-speed digital systems. It features ±32mA/64mA output drive, power-off disable for live insertion, 5V ±10% supply operation, hysteresis on all inputs, and operates across –40°C to +85°C. It is used in backplane driver applications requiring robust signal integrity and hot-swap capability.
For engineers reviewing the PI74FCT16245ATV datasheet, PI74FCT16245ATV pinout, PI74FCT16245ATV application, or PI74FCT16245ATV equivalent, key selection criteria include bidirectional bus isolation timing (tPLH/tPHL ≤ 4.1 ns), output enable/disable latency (tPZH/tPHZ ≤ 5.8 ns), ground bounce performance (VOLP < 1.0V), and compatibility with 48-pin TVSOP (K48) packaging for space-constrained PCB layouts.
Technical Context
The PI74FCT16245ATV implements dual 8-bit or unified 16-bit bidirectional data transfer via independent direction (xDIR) and output enable (xOE) controls per port pair. Its CMOS-based FCT logic architecture delivers TTL-compatible input thresholds (VIH = 2.0V, VIL = 0.8V) with hysteresis to suppress noise-induced switching.
It supports live insertion through power-off disable functionality-outputs enter high-impedance when VCC = 0V-and integrates low-ground-bounce output buffers (typical VOLP < 1.0V at 5V/25°C), eliminating need for external termination in most backplane interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5V ±10% - compatible with standard TTL/CMOS system rails without regulation overhead |
| IOH/IOL Drive | –32mA / 64mA - drives heavy capacitive loads (e.g., long traces, multiple receivers) without signal degradation |
| tPLH/tPHL | ≤4.1 ns (max) at CL = 50pF - enables >200 MHz data throughput in synchronous bus designs |
| VOLP (Ground Bounce) | <1.0V typical at VCC = 5V - reduces simultaneous switching noise in dense backplane environments |
| Operating Temp | –40°C to +85°C - qualified for industrial-grade embedded and telecom infrastructure use |
| Input Hysteresis | 100 mV - rejects transient noise on control lines (xDIR/xOE) in electrically noisy chassis |
| Power-Off Disable | IOFF ≤ ±100 µA at VCC = 0V - enables safe hot-plug insertion into powered backplanes |
Pinout & Package
PI74FCT16245ATV is housed in a 48-pin JEDEC-standard TVSOP package (173 mil width, K48 footprint), optimized for high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A0–1A7, 2A0–2A7 | Port A I/O | Bidirectional data lines for first/second 8-bit segment of Side A bus |
| 1B0–1B7, 2B0–2B7 | Port B I/O | Bidirectional data lines for first/second 8-bit segment of Side B bus |
| 1DIR, 2DIR | Direction Control Input | Active-HIGH logic selects data flow direction (A→B or B→A) per port pair |
| 1OE, 2OE | Output Enable Input | Active-LOW control places corresponding A/B ports in high-impedance state |
| VCC | Power Supply | 5V ±10% main supply rail; powers internal logic and output drivers |
| GND | Ground Reference | Common return path for logic and I/O; critical for ground bounce suppression |
Key Features
| Feature | Design Value |
|---|---|
| High-current drive | –32mA IOH / 64mA IOL enables direct connection to unterminated transmission lines up to 15 cm |
| Live-insertion support | Power-off disable (IOFF ≤ ±100 µA at VCC = 0V) prevents backfeeding during hot-swap events |
| Noise-immune inputs | Hysteresis (100 mV) on all control and data pins rejects EMI in industrial rack-mounted systems |
| Low ground bounce | VOLP < 1.0V typical ensures signal integrity during simultaneous 16-bit switching on shared ground planes |
Applications
| Backplane Data Routing | Industrial PLC I/O Expansion |
|---|---|
Use Scenario: Bidirectional data exchange between CPU module and peripheral carrier boards in modular rack systems. IC Role / Device Role / Timing Role: Bus transceiver isolating upstream/downstream data paths while maintaining timing coherence across hot-swappable slots. Use Value: Enables deterministic 16-bit transfers at ≤4.1 ns propagation delay with no external termination, reducing BOM count and layout complexity. | Use Scenario: Interfacing programmable logic controller (PLC) main CPU with distributed I/O modules over extended backplane traces. IC Role / Device Role / Timing Role: Level-shifting and bus-isolation transceiver supporting TTL-compatible signaling across noisy factory-floor environments. Use Value: Hysteresis and low VOLP ensure reliable operation despite ground potential differences and EMI from motor drives and solenoids. |

Use Scenario: Connecting FPGA-based packet processing engines to SERDES PHYs and management microcontrollers on line cards. IC Role / Device Role / Timing Role: Synchronous bidirectional data bridge enabling configuration updates and status reporting without bus contention. Use Value: Dual 8-bit mode allows independent control of control/status vs. payload buses, improving debug visibility and fault isolation. | Use Scenario: Arbitrating shared test bus access among multiple DUT interface modules in automated test equipment (ATE). IC Role / Device Role / Timing Role: Direction-controlled bus gate preventing signal collisions during parallel device programming sequences. Use Value: Fast enable/disable timing (tPZH ≤ 5.8 ns) minimizes arbitration overhead, increasing test throughput in high-volume production. |
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 |
|---|---|---|---|
| 74FCT16245CTPV | Same FCT family, but rated for commercial temp range (0°C to +70°C); lacks power-off disable | Suitable only for non-hot-swap, ambient-controlled environments like desktop peripherals | Select when cost sensitivity outweighs industrial temperature or live-insertion requirements |
| SN74LVCH16245A | 3.3V-only operation; lower drive (±24mA); no power-off disable; different pinout | Requires level translation for 5V systems; incompatible with existing 5V backplane designs | Choose only for new 3.3V-only architectures where voltage scaling is mandatory |
Compared with 74FCT16245CTPV and SN74LVCH16245A, PI74FCT16245ATV uniquely combines industrial temperature range, live-insertion capability, and 5V-compatible high-drive performance-making it irreplaceable in legacy 5V backplane upgrades and ruggedized modular systems.

FAQ
Is PI74FCT16245ATV pin-compatible with other PI74FCT162xx variants?
Yes-PI74FCT16245ATV shares identical pinout and package (48-pin TVSOP/K48) with PI74FCT162245T and PI74FCT162H245T. However, functional differences exist: only the '45ATV variant provides –32mA/64mA drive and power-off disable; the '245T offers ±24mA balanced drive, and the 'H245T adds bus-hold inputs. Direct substitution requires verification of drive strength and control feature requirements.
What is the maximum recommended trace length for PI74FCT16245ATV driving a 50pF load?
At 5V supply and 25°C, PI74FCT16245ATV maintains signal integrity up to 15 cm (6 inches) on FR-4 PCBs with 50pF total load-including stub capacitance and receiver inputs-due to its controlled edge rate and low ground bounce (<1.0V). Beyond this, series termination or reduced data rate is advised to prevent overshoot/undershoot exceeding 10% of VCC.
Does PI74FCT16245ATV require external pull-up or pull-down resistors on control pins?
No-PI74FCT16245ATV incorporates hysteresis (100 mV) on all inputs, including xDIR and xOE, which inherently rejects noise and eliminates need for external biasing. Pull-ups/pull-downs are unnecessary unless system-level reset sequencing mandates defined initial states before power stabilization.
Can PI74FCT16245ATV operate reliably at VCC = 4.5V?
Yes-its specified VCC range is 5V ±10%, meaning 4.5V to 5.5V. At 4.5V, VOH remains ≥2.0V (min) with –32mA load and VOL stays ≤0.55V (max) with 64mA sink, satisfying TTL input thresholds. Propagation delay increases by ≤15% versus 5.0V, remaining within 4.7 ns max for timing-critical designs.
