Product details
Overview
54FCT162245CTEB from Renesas Electronics (formerly IDT) is a military-grade 16-bit bidirectional transceiver built in 0.5 µm CMOS, operating at 5V with ±16 mA balanced drive, 1.5–4.5 ns propagation delay, and –55°C to +125°C temperature range. It enables synchronous bus-to-bus communication in avionics data backplanes.
For engineers reviewing the 54FCT162245CTEB datasheet, 54FCT162245CTEB pinout, 54FCT162245CTEB application, or 54FCT162245CTEB equivalent, key selection criteria include military-qualified timing skew (<0.5 ns), dual 8-bit/16-bit configurable operation, hysteresis-enhanced noise immunity, and CERPACK package compatibility with MIL-STD-883 Class B screening.
Technical Context
This device implements two independent 8-bit transceiver blocks or one unified 16-bit path via dedicated xDIR and xOE control pins per side. Direction control is asynchronous and overrides output enable, supporting real-time bus arbitration without clock dependency.
All I/O pins feature hysteresis (≥100 mV), input leakage ≤±1 µA, and absolute terminal voltage ratings of –0.5 V to VCC+0.5 V. Output drivers integrate current-limiting resistors to suppress ground bounce (<0.6 V typical) and control fall times-eliminating need for external series termination.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5.0 V ±10% - fixed single-rail operation compatible with legacy TTL and CMOS logic families |
| Operating Temp | –55°C to +125°C - fully qualified for military airborne and ground vehicle systems |
| tPLH / tPHL | 1.5–4.5 ns - ensures sub-5 ns signal transfer across 16-bit parallel paths at full speed |
| IOL / IOH | ±16 mA - sufficient drive strength for stub-loaded MIL-STD-1553 or ARINC-429 bus interfaces |
| tSK(o) | <0.5 ns - guarantees deterministic inter-bit timing alignment critical for synchronous data capture |
| VIL / VIH | 0.8 V / 2.0 V - TTL-compatible input thresholds enabling direct interfacing with legacy controllers |
| CIN / COUT | ≤6 pF / ≤8 pF - low capacitive loading preserves signal integrity on high-speed backplane traces |
Pinout & Package
54FCT162245CTEB is supplied in a 48-pin CERPACK (ceramic flatpack) package, screened to MIL-STD-883 Class B, with hermetic sealing and lead finish suitable for high-reliability military environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction Control Input (Active HIGH) | Determines data flow direction per 8-bit bank: HIGH = A→B, LOW = B→A |
| 1OE, 2OE | Output Enable Input (Active LOW) | Disables both A and B ports to high-impedance state when asserted |
| 1A1–1A8, 2A1–2A8 | Side A I/O Terminals | Bi-directional data lines for first and second 8-bit bus segment (A-side) |
| 1B1–1B8, 2B1–2B8 | Side B I/O Terminals | Bi-directional data lines for corresponding B-side bus segments |
| VCC (Pins 5, 11, 20, 24, 33, 40, 47) | Power Supply | Multiple distributed VCC pins reduce power delivery impedance and improve noise rejection |
| GND (Pins 3, 7, 10, 14, 17, 22, 23, 27, 30, 36, 39, 43, 46) | Ground Reference | 13 dedicated GND pins ensure low-inductance return paths for all 16 I/Os and controls |
Key Features
| Feature | Design Value |
|---|---|
| Balanced ±16 mA drive | Enables robust signal transmission over long backplane traces without external termination resistors |
| Hysteresis ≥100 mV | Improves noise margin by >2× versus standard CMOS, critical in EMI-heavy military enclosures |
| Output skew <0.5 ns | Ensures simultaneous valid sampling of all 16 bits at destination bus, preventing setup/hold violations |
| MIL-STD-883 Class B screening | Includes burn-in, temperature cycling, and hermeticity testing-required for DoD procurement compliance |
| Low ground bounce <0.6 V | Minimizes supply rail disturbance during simultaneous switching, preserving adjacent analog circuitry |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 54FCT162245AT | Same core logic but industrial temperature range (–40°C to +85°C); SSOP/TSSOP packaging only | Not qualified for airborne or space-qualified platforms requiring extended thermal margins | Select 54FCT162245AT only for commercial or non-safety-critical ground systems where cost and footprint are prioritized over military screening. |
| SNJ54ABT16245J | Pin-compatible ABT-family part; higher drive (±64 mA), no hysteresis, no skew guarantee | Lacks hysteresis and skew specification-unsuitable for noise-sensitive or timing-critical synchronous buses | Choose SNJ54ABT16245J only when maximum drive strength is primary requirement and timing determinism is secondary. |
Compared with 54FCT162245AT and SNJ54ABT16245J, the 54FCT162245CTEB uniquely delivers military-temperature operation, guaranteed <0.5 ns output skew, and hysteresis-enhanced noise immunity-making it the sole option for deterministic, high-integrity 16-bit bus bridging in flight-critical systems.

FAQ
What is the operating temperature range specified for the 54FCT162245CTEB?
The 54FCT162245CTEB is rated for –55°C to +125°C operation, meeting military environmental requirements per MIL-STD-810 and qualified to MIL-STD-883 Class B. This range is explicitly defined in the datasheet's DC electrical characteristics table and confirmed by its CERPACK packaging and screening process. The 54FCT162245CTEB maintains full functionality-including propagation delay, drive strength, and noise margin-across this entire span without derating.
Does the 54FCT162245CTEB support independent 8-bit operation?
Yes, the 54FCT162245CTEB supports independent 8-bit operation via separate DIR and OE controls for each half: 1DIR/1OE governs pins 1A1–1A8 and 1B1–1B8, while 2DIR/2OE governs 2A1–2A8 and 2B1–2B8. This allows concurrent bidirectional transfers on two distinct 8-bit buses-e.g., sensor data uplink and actuator command downlink-without internal contention. The 54FCT162245CTEB's functional block diagram and truth table confirm this dual-mode capability.
What package type is used for the 54FCT162245CTEB?
The 54FCT162245CTEB is supplied exclusively in a 48-pin CERPACK (ceramic flatpack) package, identified by the "EB" suffix in the part number. This hermetically sealed, leaded ceramic package meets MIL-STD-883 mechanical and environmental test requirements and is distinct from the SSOP/TSSOP variants used for industrial versions like the 54FCT162245AT. The 54FCT162245CTEB's pin configuration diagram and ordering information section confirm CERPACK as the sole package option.
Is the 54FCT162245CTEB pin-compatible with the 54FCT162245AT?
No-the 54FCT162245CTEB and 54FCT162245AT share identical logic functionality and pin assignments, but differ in package and screening: the 54FCT162245CTEB uses CERPACK, while the 54FCT162245AT uses SSOP or TSSOP. PCB layout, thermal management, and reliability validation must be requalified for CERPACK mounting. The 54FCT162245CTEB is not a drop-in replacement due to mechanical incompatibility, though logic-level interoperability is preserved.
What is the maximum output skew guaranteed for the 54FCT162245CTEB?
The 54FCT162245CTEB guarantees output skew (tSK(o)) of less than 0.5 ns across all outputs within the same package, as stated in the Switching Characteristics table under "tSK(o) Output Skew(3)". This parameter is design-guaranteed-not tested-and applies to any two outputs switching in the same direction. The 54FCT162245CTEB's skew performance enables reliable capture of 16-bit parallel data at >200 MHz effective bus rates without bit misalignment.
