Product details
Overview
54FCT16244CTEB from Renesas Electronics (formerly IDT) is a military-grade 16-bit non-inverting 3-state buffer/line driver with high-drive capability (–32mA IOH, 64mA IOL), flow-through pinout, and power-off disable for live insertion in backplane systems. It operates over –55°C to +125°C at 5.0V ±10%, supports independent 4-/8-/16-bit control via four active-low OE inputs, and targets high-capacitance (>200pF) and low-impedance bus driving.
For engineers reviewing the 54FCT16244CTEB datasheet, 54FCT16244CTEB pinout, 54FCT16244CTEB application, or 54FCT16244CTEB equivalent, key selection criteria include output skew < 0.5ns, input hysteresis (100mV), TTL-compatible inputs, MIL-STD-883 Class B qualification, and CERPACK packaging for ruggedized embedded and aerospace interfaces.
Technical Context
This device implements a quad 4-bit buffered driver architecture with fully independent 3-state controls (1OE–4OE), enabling flexible partitioning of the 16-bit bus. Each 4-bit group features matched propagation delays (tPLH/tPHL ≤ 7ns max), sub-nanosecond output skew (tSK(o) ≤ 0.5ns), and guaranteed noise immunity via input hysteresis.
Designed for backplane interconnect, it delivers rail-to-rail drive strength under heavy capacitive loading while maintaining low ground bounce (VOLP < 1.0V at VCC = 5V). Power-off disable ensures outputs remain high-impedance when VCC = 0V, supporting hot-swap compliance without external isolation circuitry.

Pinout & Package
54FCT16244CTEB is housed in a 48-pin CERPACK (ceramic flatpack) package, designed for hermetic sealing and thermal stability in extreme environments. Pin numbering follows standard top-view layout with dual-row staggered configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE–4OE | Active-low 3-state enable inputs | Independent control of each 4-bit segment; all must be LOW to enable corresponding Y outputs |
| 1A1–1A4, 2A1–2A4, 3A1–3A4, 4A1–4A4 | Non-inverting data inputs | 16 total inputs mapped 1:1 to respective output groups; TTL-compatible thresholds |
| 1Y1–1Y4, 2Y1–2Y4, 3Y1–3Y4, 4Y1–4Y4 | 3-state non-inverting outputs | High-drive outputs with power-off disable; float to Hi-Z when OE HIGH or VCC = 0V |
| VCC (Pins 4, 11, 24, 36, 47) | Positive supply | Multiple distributed VCC pins reduce IR drop and improve noise immunity on large ceramic substrate |
| GND (Pins 2, 10, 23, 35, 48) | Ground reference | Five dedicated GND pins provide low-inductance return paths for high-current switching |
Key Features
| Feature | Design Value |
|---|---|
| Flow-through pinout | Input-to-output signal path aligned across package edges-reduces PCB trace length and crosstalk in dense layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit buffer/line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 54FCT16244TEB | Same core logic and drive strength, but uses TSSOP package instead of CERPACK; lacks MIL-STD-883 Class B screening | Suitable for industrial-grade systems where hermeticity and extended temperature are not required | Select when cost, board space, or reflow compatibility outweigh military qualification needs |
| SNJ54ABT16244FK | Pin-compatible ABT-family predecessor; higher ICC (up to 1.5mA quiescent), no power-off disable, lower drive (–24mA/+48mA) | Legacy replacement only; not recommended for new designs requiring live insertion or low ground bounce | Choose only for backward compatibility in existing ABT-based boards undergoing minimal redesign |
Compared with 54FCT16244TEB and SNJ54ABT16244FK, the 54FCT16244CTEB uniquely combines MIL-STD-883 Class B qualification, power-off disable, and sub-0.5ns skew-making it the sole option for safety-critical hot-swap and high-integrity timing applications.

FAQ
What is the operating temperature range for the 54FCT16244CTEB?
The 54FCT16244CTEB is rated for operation from –55°C to +125°C and qualified per MIL-STD-883 Class B. This full military temperature range ensures reliable functionality in harsh environments such as aircraft avionics bays, missile guidance systems, and tracked vehicle engine compartments where thermal extremes are routine. The 54FCT16244CTEB maintains specified timing and drive performance across this entire range at 5.0V ±10% supply.
Does the 54FCT16244CTEB support live insertion into powered backplanes?
Yes, the 54FCT16244CTEB supports live insertion due to its power-off disable feature: when VCC = 0V, all outputs automatically enter high-impedance state with leakage ≤ ±1μA. This prevents bus contention and protects downstream circuitry during hot-swap events in modular avionics or secure comms chassis. The 54FCT16244CTEB's CERPACK package further enhances mechanical robustness during repeated insertion cycles.
What is the maximum capacitive load the 54FCT16244CTEB can drive reliably?
The 54FCT16244CTEB is explicitly characterized for driving high-capacitance loads exceeding 200pF, as confirmed in its datasheet description and output drive specifications. Its –32mA/64mA drive strength, low output impedance, and sub-1.0V ground bounce (VOLP) ensure signal fidelity even into heavily loaded backplanes or long parallel bus traces. The 54FCT16244CTEB maintains tPLH/tPHL ≤ 7ns under CL = 50pF, scaling predictably to larger loads with controlled edge rates.
How many independent 3-state control inputs does the 54FCT16244CTEB have?
The 54FCT16244CTEB has four independent active-low 3-state enable inputs: 1OE, 2OE, 3OE, and 4OE. Each controls a distinct 4-bit segment (e.g., 1OE enables 1Y1–1Y4), allowing flexible partitioning of the 16-bit bus for partial-width transfers or mixed-direction data routing. This architecture is documented in the functional block diagram and pin description section of the 54FCT16244CTEB datasheet.
Is the 54FCT16244CTEB pin-compatible with the 54FCT16244TEB?
No-the 54FCT16244CTEB and 54FCT16244TEB share identical logic function, electrical specifications, and pin assignment, but differ in package type and qualification: the CT variant uses CERPACK (hermetic ceramic) with MIL-STD-883 Class B screening, while the TE variant uses TSSOP (plastic) without military screening. Their pinouts match exactly, but mechanical fit, thermal performance, and reliability testing are not interchangeable. Always verify board footprint and qualification requirements before substitution.
