Product details
Overview
54FCT162244ATEB from Renesas Electronics (formerly IDT) is a military-grade 16-bit non-inverting 3-state buffer/line driver with balanced ±16mA output drive, 4.1ns max propagation delay (tPLH/tPHL), and flow-through pinout in CERPACK package. It operates from –55°C to +125°C at 5.0V ±10%, serving bus interface and signal buffering in high-reliability avionics and defense systems.
For engineers reviewing the 54FCT162244ATEB datasheet, 54FCT162244ATEB pinout, 54FCT162244ATEB application, or 54FCT162244ATEB equivalent, key selection criteria include military temperature compliance, output skew <0.5ns, ground bounce <0.6V, hysteresis-enhanced noise margin, and independent 4-/8-/16-bit 3-state control via four OE inputs.
Technical Context
This device implements a fast CMOS buffer architecture with TTL-compatible inputs, hysteresis on all inputs for noise immunity, and current-limiting output drivers to suppress ground bounce and undershoot. Its flow-through pinout minimizes PCB trace crossovers and reduces layout complexity in dense backplane or module interconnect designs.
The four independent 3-state enable inputs (1OE–4OE) allow granular control of four 4-bit groups, enabling flexible bus segmentation without external logic. Output drive strength is fixed at ±16mA (military grade), with guaranteed VOL ≤0.55V at 16mA sink and VOH ≥2.4V at 16mA source under worst-case VCC min and temperature extremes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 5.0V ±10% - supports standard military 5V rail with no regulation overhead |
| Operating Temperature | –55°C to +125°C - qualified per MIL-STD-883 Class B for aerospace and defense deployment |
| Propagation Delay | Max 4.1ns (tPLH/tPHL, CL=50pF) - enables >200MHz bus operation with timing margin |
| Output Skew | <0.5ns - ensures simultaneous switching across all 16 outputs for clean bus transitions |
| Output Drive | ±16mA (military) - sufficient to drive 50Ω transmission lines or multiple TTL loads without external termination |
| Input Hysteresis | 100mV - improves noise immunity on noisy chassis or long cable runs |
| Ground Bounce | <0.6V at VCC=5V - eliminates need for external series resistors in most low-capacitance (<200pF) loads |
Pinout & Package
CERPACK (Ceramic Dual-In-Line Package) with 48 leads, hermetically sealed for harsh-environment reliability and MIL-STD-883 qualification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE–4OE | Active-Low 3-State Enable Inputs | Independent control of four 4-bit output groups; asserted LOW enables corresponding Y outputs |
| 1A1–1A4, 2A1–2A4, 3A1–3A4, 4A1–4A4 | Data Inputs | 16 TTL-compatible inputs with hysteresis; accept VIH ≥2.0V, VIL ≤0.8V |
| 1Y1–1Y4, 2Y1–2Y4, 3Y1–3Y4, 4Y1–4Y4 | 3-State Non-Inverting Outputs | 16 buffered outputs with ±16mA drive, controlled by respective OE; HIGH-Z when OE=HIGH |
| VCC (Pins 4, 11, 20, 29, 40) | Power Supply | Five distributed VCC pins reduce supply impedance and improve noise rejection across wide temperature range |
| GND (Pins 2, 10, 19, 28, 39, 48) | Ground | Six GND pins provide low-inductance return paths critical for minimizing ground bounce in high-speed switching |
Key Features
| Feature | Design Value |
|---|---|
| Balanced ±16mA Output Drive | Enables direct driving of unterminated 50Ω traces or up to 10 TTL loads while maintaining VOL/VOH specs over full military temp range |
| Flow-Through Pinout | Input-to-output signal path routing simplifies PCB layout, eliminates layer jumps, and reduces crosstalk in high-density modules |
| Hysteresis on All Inputs | 100mV input threshold hysteresis rejects EMI-induced glitches on long harnesses or noisy power domains |
| Low Ground Bounce (<0.6V) | Current-limiting output structure suppresses simultaneous switching noise, eliminating need for external series resistors in typical applications |
| Independent 4-Bit 3-State Control | Four OE pins allow selective activation of 4-, 8-, or 16-bit segments - essential for partial bus arbitration and power-gated subsystems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 54FCT162244T | No "A" speed grade: slower max tPLH/tPHL = 7ns vs. 4.1ns; same military temp and CERPACK package | Acceptable where bus clock rates ≤100MHz; higher timing margin but lower performance ceiling | Select 54FCT162244T only if system timing budget allows ≥3ns additional delay per stage |
| SNJ54ABT16244J | Higher power consumption (ICCL up to 500µA vs. 5µA), no hysteresis, no ground bounce spec; same pinout and military rating | Legacy drop-in replacement where noise immunity and signal integrity are secondary to cost or legacy qualification | Choose SNJ54ABT16244J only when redesign is prohibited and existing ABT-based layouts must be reused without modification |
Compared with 54FCT162244ATEB, the 54FCT162244T offers identical ruggedization but sacrifices 30% speed; SNJ54ABT16244J matches footprint and temperature range but lacks hysteresis and ground-bounce control-critical for modern high-speed, low-noise military systems.

FAQ
What is the maximum operating frequency supported by the 54FCT162244ATEB?
The 54FCT162244ATEB does not specify a maximum clock frequency directly, but its 4.1ns maximum propagation delay (tPLH/tPHL) and <0.5ns output skew enable reliable operation on buses with cycle times ≥8.2ns - supporting effective data rates up to ~120MHz in synchronous applications with adequate setup/hold margins. Actual usable frequency depends on load capacitance and board layout.
Is the 54FCT162244ATEB RoHS compliant?
Yes, the 54FCT162244ATEB is RoHS compliant and lead-free, as confirmed by Renesas' ordering information indicating "PVG" (Pb-Free Green) suffix in the package code. It meets EU Directive 2011/65/EU and associated exemptions applicable to military-grade components.
Does the 54FCT162244ATEB require external pull-up or pull-down resistors on its OE inputs?
No, the 54FCT162244ATEB OE inputs are TTL-compatible with defined VIH ≥2.0V and VIL ≤0.8V, and include internal hysteresis. When driven directly from CMOS or TTL logic outputs, no external biasing resistors are needed - OE asserts active-low cleanly without floating states.
Can the 54FCT162244ATEB drive a 50Ω transmission line directly?
Yes, the 54FCT162244ATEB's ±16mA balanced output drive and controlled fall times allow direct connection to unterminated 50Ω PCB traces or cables with capacitive loads <200pF. Its low ground bounce (<0.6V) and minimal undershoot eliminate the need for external series termination in most military backplane implementations.
What is the meaning of the "ATEB" suffix in 54FCT162244ATEB?
In the 54FCT162244ATEB part number, "AT" denotes the advanced speed grade (vs. "T" or "CT"), "E" indicates the military temperature range (–55°C to +125°C), and "B" specifies MIL-STD-883 Class B qualification. The full suffix confirms it is a high-speed, fully screened military device in CERPACK packaging.
