Product details
Overview
54FCT16245CTEB from Renesas Electronics (formerly IDT) is a military-grade 16-bit bidirectional transceiver built in 0.5 µm CMOS, operating at 5V with ±10% tolerance across –55°C to +125°C. It features dual 8-bit or unified 16-bit operation via DIR/OE controls, –32 mA/64 mA drive strength, and power-off disable for live insertion in backplane applications.
For engineers reviewing the 54FCT16245CTEB datasheet, 54FCT16245CTEB pinout, 54FCT16245CTEB application, or 54FCT16245CTEB equivalent, key selection criteria include output skew < 0.5 ns, TTL-compatible inputs with hysteresis, high-drive capability for low-impedance buses, and CERPACK packaging qualified per MIL-STD-883 Class B.
Technical Context
The 54FCT16245CTEB implements two independent direction-controlled 8-bit data paths (A↔B), each governed by dedicated xDIR and xOE pins. Its dual-metal CMOS process enables fast propagation delays (tPLH/tPHL ≤ 7.5 ns max) while maintaining low quiescent current (ICCL ≤ 500 µA) and tight output skew (tSK(o) ≤ 0.5 ns).
All I/O pins support 5V TTL logic levels with guaranteed VIH ≥ 2.0 V and VIL ≤ 0.8 V, and input hysteresis (VH = 100 mV) improves noise immunity. Power-off leakage (IOFF ≤ ±1 µA at VCC = 0 V) ensures safe hot-swap operation without bus contention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 5.0 V ±10% - supports stable operation across military temperature range (–55°C to +125°C) |
| Propagation Delay | tPLH/tPHL ≤ 7.5 ns (max) - enables high-speed synchronous bus bridging up to ~133 MHz system timing |
| Output Drive | –32 mA IOH / 64 mA IOL - drives heavy capacitive loads (e.g., >100 pF backplanes) without signal degradation |
| Output Skew | tSK(o) ≤ 0.5 ns - ensures deterministic timing alignment across all 16 outputs for parallel data integrity |
| Power-off Leakage | IOFF ≤ ±1 µA at VCC = 0 V - permits live insertion/removal without damaging connected circuitry |
| Input Hysteresis | VH = 100 mV - rejects noise on control lines (xDIR/xOE) in electrically noisy military environments |
| ESD Rating | >2000 V HBM, >200 V MM - meets MIL-STD-883 Method 3015 for ruggedized board-level reliability |
Pinout & Package
54FCT16245CTEB is supplied in a 48-pin CERPACK (ceramic flatpack) package, hermetically sealed and qualified to MIL-STD-883 Class B for high-reliability military systems. Pin layout supports dual 8-bit transceiver configuration with separate direction and enable controls per side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction Control Inputs (Active HIGH) | Set data flow direction per 8-bit port: DIR = H → A→B; DIR = L → B→A |
| 1OE, 2OE | Output Enable Inputs (Active LOW) | Disable both A/B ports to high-impedance when asserted (OE = L) |
| 1A1–1A8, 2A1–2A8 | Port A I/O Terminals | Bi-directional data terminals for first and second 8-bit bus segments |
| 1B1–1B8, 2B1–2B8 | Port B I/O Terminals | Bi-directional data terminals paired with respective A-side ports |
| VCC (Pins 5, 10, 20, 24, 33, 37, 40, 44) | Power Supply | Eight distributed VCC pins minimize IR drop and improve noise immunity across wide ceramic body |
| GND (Pins 3, 7, 12, 16, 22, 26, 30, 34, 38, 41, 45, 47) | Ground | Twelve GND pins provide low-inductance return paths essential for clean switching in high-speed backplanes |
Key Features
| Feature | Design Value |
|---|---|
| Live-insertion support | Power-off disable outputs prevent bus contention during hot-swap of backplane cards using 54FCT16245CTEB |
| TTL-compatible inputs | VIH ≥ 2.0 V and VIL ≤ 0.8 V ensure interoperability with legacy 5V TTL logic families without level-shifting |
| Low-output ground bounce | VOLP < 1.0 V at VCC = 5 V - reduces simultaneous switching noise in dense PCB layouts |
| Military qualification | MIL-STD-883 Class B screening and –55°C to +125°C operation meet DO-254 and MIL-HDBK-217F requirements |
| High-noise-margin design | 100 mV input hysteresis on all control pins suppresses false triggering in EMI-prone avionics and radar subsystems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 54FCT16245AT | Same core logic but industrial temperature range (–40°C to +85°C); TSSOP package; no MIL-STD-883 screening | Suitable for non-mission-critical ground-station equipment where extended temperature is not required | Select 54FCT16245AT only if CERPACK hermeticity and military screening are unnecessary |
| SNJ54ABT16245J | TI ABT-family variant: higher drive (–64 mA/128 mA), faster tPLH/tPHL (≤5.5 ns), but no power-off disable or hysteresis | Better for ultra-high-speed commercial backplanes; lacks live-insertion capability and military environmental robustness | Choose SNJ54ABT16245J only when maximum speed outweighs need for hot-swap safety and noise immunity |
Compared with 54FCT16245AT and SNJ54ABT16245J, the 54FCT16245CTEB uniquely combines MIL-qualified CERPACK packaging, power-off disable, and input hysteresis-making it irreplaceable in safety-critical, field-deployable systems requiring guaranteed operation across extreme thermal and EMI conditions.

FAQ
What is the operating temperature range specified for the 54FCT16245CTEB?
The 54FCT16245CTEB is rated for operation from –55°C to +125°C, meeting military environmental requirements per its CERPACK packaging and MIL-STD-883 Class B qualification. This range is explicitly defined in the datasheet's "DC Electrical Characteristics" section and confirmed in the Ordering Information table. The device maintains full functionality-including propagation delay, drive strength, and noise margin-across this entire span without derating.
Does the 54FCT16245CTEB support live insertion, and how is this implemented?
Yes, the 54FCT16245CTEB supports live insertion through its power-off disable feature: when VCC = 0 V, output leakage current (IOFF) is limited to ±1 µA, placing all I/O pins in high-impedance state without bus contention. This behavior is verified in the "DC Electrical Characteristics" table and enables safe hot-swap of backplane cards. The 54FCT16245CTEB's CERPACK package further enhances mechanical stability during insertion cycles.
What are the absolute maximum ratings for input voltage on the 54FCT16245CTEB?
The 54FCT16245CTEB specifies two absolute maximum input voltage limits: VTERM(2) = –0.5 V to +7.0 V for non-I/O pins, and VTERM(3) = –0.5 V to VCC + 0.5 V for A-port I/O terminals. These values appear in the "Absolute Maximum Ratings" table and define safe voltage boundaries before permanent damage occurs. Exceeding them-even briefly-violates the device's reliability warranty and may compromise MIL-STD-883 qualification.
How does the direction control logic function on the 54FCT16245CTEB?
The 54FCT16245CTEB uses two independent direction control inputs (1DIR and 2DIR) to set data flow per 8-bit port: when DIR = HIGH, data flows from A to B; when DIR = LOW, data flows from B to A. This mapping is defined in the "Function Table" and validated in the "Pin Description" section. The 54FCT16245CTEB does not support mixed-direction operation within a single 8-bit group-each side operates coherently under its own DIR signal.
Is the 54FCT16245CTEB pin-compatible with other members of the FCT16245 family?
Yes, the 54FCT16245CTEB shares identical pinout and functional behavior with 54FCT16245T, 54FCT16245AT, and 54FCT16245ET variants-all use the same 48-pin CERPACK footprint and logic definition. Differences lie solely in speed grade (propagation delay), temperature range, and screening level-not pin assignment or electrical interface. This compatibility is confirmed in the "Pin Configuration" diagram and "Ordering Information" table.
