Product details
Overview
PI74FCT16245TVE from Pericom Semiconductor is a 16-bit bidirectional CMOS transceiver in 48-pin SSOP (V) package, operating at 5V ±10%, with high-current drive (–32mA IOH / 64mA IOL), power-off disable for live insertion, and typical output ground bounce <1.0V. It enables asynchronous two-way data bus communication in backplane and hot-swap systems.
For engineers reviewing the PI74FCT16245TVE datasheet, PI74FCT16245TVE pinout, PI74FCT16245TVE application, or PI74FCT16245TVE equivalent, key selection criteria include direction-controlled bidirectional flow, 3-state enable logic, high-impedance isolation during power-down, and low-noise switching performance under 5V TTL-compatible operation.
Technical Context
The PI74FCT16245TVE implements dual 8-bit or unified 16-bit bidirectional data transfer via independent DIR and OE controls per port pair. Its fast CMOS architecture delivers propagation delays as low as 1.5ns (min) and ≤7.0ns (max) at CL = 50pF/RL = 500Ω, with guaranteed output skew ≤0.5ns across all outputs.
It features hysteresis on all inputs for noise immunity, power-off disable enabling live board insertion, and balanced high-drive capability optimized for backplane driver applications requiring robust signal integrity and controlled edge rates without external termination.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5V ±10% - compatible with standard TTL/CMOS logic rails and industrial 5V systems |
| IOH / IOL Drive | –32mA / 64mA - supports driving heavy capacitive loads and long traces without buffering |
| Propagation Delay | 1.5–7.0ns - ensures timing-critical synchronous bus handshaking up to ~140MHz effective rate |
| Output Ground Bounce | <1.0V typical - minimizes supply rail disturbance during simultaneous switching |
| Power-Off Disable | ±100µA leakage at VCC = 0V - maintains Hi-Z state during hot insertion, preventing bus contention |
| Input Hysteresis | 100mV - rejects noise on control lines (DIR/OE) in electrically noisy environments |
| Operating Temp | –40°C to +85°C - qualified for industrial temperature range operation |
Pinout & Package
PI74FCT16245TVE uses a 48-pin 300-mil wide plastic SSOP (Package Code V), with exposed pad not present and lead-free/Green compliant construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction Control Input | Determines data flow direction per 8-bit port (L: B→A; H: A→B) |
| 1OE, 2OE | 3-State Enable Input (Active LOW) | Disables both A/B ports to Hi-Z when HIGH; enables bidirectional transfer when LOW |
| 1A0–1A7, 2A0–2A7 | Port A I/O Terminals | Side-A data bus interface; function as inputs or 3-state outputs based on DIR/OE state |
| 1B0–1B7, 2B0–2B7 | Port B I/O Terminals | Side-B data bus interface; mirror behavior of corresponding A-side pins |
| VCC (Pins 7, 22, 37) | Power Supply | Three distributed VCC pins reduce IR drop and improve noise margin across wide bus |
| GND (Pins 4, 19, 34) | Ground Reference | Three dedicated GND pins provide low-inductance return paths for high-speed switching |
Key Features
| Feature | Design Value |
|---|---|
| Live Insertion Support | Power-off disable limits leakage to ±100µA at VCC = 0V, enabling safe hot-plug into live backplanes |
| High-Drive Output Buffers | –32mA IOH / 64mA IOL allows direct interfacing with unterminated transmission lines and legacy TTL loads |
| Low Ground Bounce | Typical VOLP <1.0V at 5V/25°C ensures stable VCC rail during full-bus switching events |
| Configurable Port Width | Two independent 8-bit transceivers or one unified 16-bit path via separate DIR/OE controls per side |
| Noise-Immune Inputs | 100mV input hysteresis prevents false triggering on slow or noisy control signals (DIR/OE) |
Applications

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 |
|---|---|---|---|
| SN74FCT16245CTPVR | Same FCT family, but TI variant with slightly higher ICC (2.5mA max vs 0.7–2.5mA), identical pinout and logic | Designed for TI-centric BOMs; same industrial temp range and 5V operation | Select if sourcing from TI distribution channels or requiring TI-specific qualification documentation |
| 74ALVC16245DGG | Lower voltage (1.65–3.6V), 3.6V-tolerant I/O, 24mA drive - not 5V-native or pin-compatible | Targeted at mixed-voltage portable/embedded systems, not 5V backplane use | Only consider for new low-voltage designs; requires level-shifting and layout redesign |
Compared with SN74FCT16245CTPVR and 74ALVC16245DGG, the PI74FCT16245TVE offers superior 5V drive strength (64mA IOL), lower quiescent current (0.1–0.7mA), and verified live-insertion behavior - making it optimal for industrial backplane and hot-swap applications where 5V compatibility and robustness are mandatory.

FAQ
What is the maximum capacitive load the PI74FCT16245TVE can drive reliably?
The device is characterized at CL = 50pF with guaranteed propagation delay ≤7.0ns. Its –32mA/64mA drive strength supports heavier loads - typical design margin allows stable operation up to 100pF with minor timing degradation, provided PCB layout minimizes stub length and maintains controlled impedance.
Does PI74FCT16245TVE support mixed-voltage operation between Port A and Port B?
No. The PI74FCT16245TVE has a single VCC pin (5V ±10%) supplying both sides; it does not support independent voltage domains. Both A and B ports operate at the same 5V logic level and share common supply and ground references.
Can PI74FCT16245TVE be used without external pull-up or pull-down resistors on DIR/OE inputs?
Yes. All inputs feature built-in hysteresis (100mV) and TTL-compatible thresholds (VIH = 2.0V, VIL = 0.8V). With clean control signals, external biasing is unnecessary - though pull-downs are recommended in noisy environments to ensure defined state at power-up.
Is the PI74FCT16245TVE RoHS-compliant and halogen-free?
Yes. Per ordering information, the "V" suffix (PI74FCT16245TVE) denotes Pb-free & Green packaging - fully compliant with RoHS Directive 2011/65/EU and halogen-free per IEC 61249-2-21, with no brominated flame retardants or chlorine above threshold limits.
