Product details
Overview
74FCT16244ATPAG from Renesas Electronics is a 16-bit non-inverting 3-state buffer/line driver in TSSOP-48 package, designed for high-speed bus interface and backplane driving. It delivers –32mA IOH / 64mA IOL drive strength, supports industrial temperature range (–40°C to +85°C), features flow-through pinout, hysteresis-enhanced inputs, and power-off disable for live insertion.
For engineers reviewing the 74FCT16244ATPAG datasheet, 74FCT16244ATPAG pinout, 74FCT16244ATPAG application, or 74FCT16244ATPAG equivalent, key selection criteria include output skew (<250ps), ground bounce performance (VOLP <1.0V), TTL-compatible input thresholds, and independent 4-/8-/16-bit 3-state control via four OE pins.
Technical Context
This device implements a quad-grouped 4-bit buffer architecture with separate active-low 3-state enable inputs (1OE–4OE), enabling flexible partitioning of the 16-bit bus. Each group drives four outputs (e.g., 1Y1–1Y4) from corresponding inputs (1A1–1A4), with all inputs featuring hysteresis for noise immunity.
It operates at 5.0V ±10%, meets MIL-STD-883 ESD requirements (>2000V HBM), and uses 0.5µm CMOS technology to achieve typical propagation delays of 3.4ns (tPLH/tPHL) and output enable/disable times as low as 4.4ns (tPZH/tPHZ) under industrial conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5.0V ±10% - compatible with standard TTL/CMOS logic rails and ensures interoperability with legacy 5V systems. |
| IOH/IOL Drive | –32mA / 64mA - sufficient to drive >200pF loads and low-impedance backplanes without signal degradation. |
| tPLH/tPHL | 3.4ns max (industrial) - enables reliable operation in high-speed data buses up to ~150MHz system timing. |
| tSK(o) | <250ps - minimizes timing skew across outputs, critical for parallel bus integrity and setup/hold margin. |
| VIL/VIH | 0.8V / 2.0V - TTL-compatible input thresholds ensure direct interfacing with 5V microcontrollers and FPGAs. |
| Power-off Disable | IOFF ≤ ±1µA at VCC = 0V - permits safe live insertion into powered backplanes without bus contention. |
| CIN/COUT | 6pF / 8pF max - low capacitive loading preserves signal edge rates and reduces crosstalk in dense layouts. |
Pinout & Package
TSSOP-48 (Thin Shrink Small Outline Package, Green, RoHS-compliant), 12.5mm × 6.1mm body, 0.5mm pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE–4OE | Active-Low 3-State Enable Inputs | Independently control 4-bit groups; assertion disables outputs to high-impedance state for bus sharing. |
| 1A1–4A4 | Data Inputs | 16 single-ended CMOS/TTL-compatible inputs, each with hysteresis for ≥100mV noise margin. |
| 1Y1–4Y4 | Non-Inverting 3-State Outputs | 16 buffered outputs with high-drive capability; flow-through layout simplifies PCB routing. |
| VCC (Pins 24, 39, 40, 47) | Power Supply | Four dedicated VCC pins reduce supply inductance and improve switching noise immunity. |
| GND (Pins 23, 25, 32, 33, 34, 41, 42, 43) | Ground | Eight GND pins provide low-impedance return paths, minimizing ground bounce (VOLP <1.0V). |
Key Features
| Feature | Design Value |
|---|---|
| Flow-through pinout | Input-to-output signal path aligned left-to-right across package, eliminating layer jumps and reducing trace length by up to 40%. |
| Hysteresis on all inputs | 100mV typical hysteresis improves noise rejection in electrically noisy industrial environments (e.g., motor drives, PLCs). |
| Live-insertion support | Power-off disable (IOFF ≤ ±1µA) prevents backfeeding and bus conflicts during hot-swap of daughterboards. |
| Low ground bounce | VOLP <1.0V at VCC = 5V ensures stable logic LOW levels even during simultaneous 16-bit switching. |
| Quad 4-bit grouping | Four independent OE controls allow dynamic segmentation-e.g., isolate memory address vs. data lanes without full bus shutdown. |
Applications
| Industrial Backplane Interface | High-Density Memory Subsystem |
|---|---|
Use Scenario: Driving 16-bit parallel address/data buses across multi-slot VME or CompactPCI backplanes with >150pF load per line. IC Role / Device Role / Timing Role: Signal repeater and level translator between CPU module and peripheral cards, providing impedance matching and noise suppression. Use Value: High drive strength (64mA IOL) maintains signal integrity over long traces; flow-through pinout reduces stub length and reflection-induced jitter. | Use Scenario: Buffering address lines between FPGA controller and multiple SRAM/Flash devices on a shared bus. IC Role / Device Role / Timing Role: Address latch driver with independent 4-bit enables, allowing selective activation of memory banks without toggling entire bus. Use Value: 4.4ns tPZH enables fast bank switching; hysteresis prevents false triggering from FPGA output ringing. |
| Programmable Logic Carrier Board | Legacy Bus Extender Module |
Use Scenario: Interfacing Xilinx Spartan-6 FPGA I/O banks (3.3V tolerant) to 5V legacy peripherals via level-shifting buffer. IC Role / Device Role / Timing Role: Unidirectional voltage-tolerant buffer with TTL-compatible inputs, isolating FPGA from bus transients. Use Value: VIH = 2.0V allows reliable recognition of 3.3V FPGA HIGH; power-off disable protects FPGA during hot-plug events. | Use Scenario: Extending ISA or STD Bus signals from host CPU to remote I/O expansion chassis using ribbon cable. IC Role / Device Role / Timing Role: Line driver compensating for capacitance and attenuation in 1-meter+ flat cables. Use Value: –32mA/64mA drive capability sustains edge rate over 200pF load; low ICCD (60µA/MHz) minimizes dynamic power in always-on modules. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74FCT16244CPAG | Same pinout, identical AC/DC specs, but manufactured by Texas Instruments; no military-grade screening option. | Valid for industrial-only designs where Renesas qualification is not required; RoHS-compliant TSSOP-48 footprint. | Select when TI sourcing preference or dual-source strategy applies; no layout or firmware changes needed. |
| 74ABT16244CMTDX | Higher ICC (1.5mA typical), no power-off disable, 5.5V absolute max VCC vs. 7.0V for FCT; otherwise pin-compatible. | Suitable for cost-sensitive non-hot-swap applications; lacks live-insertion safety for backplane systems. | Choose only if power-off disable is unnecessary and higher quiescent current is acceptable. |
Compared with SN74FCT16244CPAG and 74ABT16244CMTDX, the 74FCT16244ATPAG uniquely combines industrial temperature rating, power-off disable, and sub-250ps output skew-making it optimal for mission-critical backplane and hot-swap embedded systems where reliability and timing precision are non-negotiable.

FAQ
What is the operating temperature range for the 74FCT16244ATPAG?
The 74FCT16244ATPAG is rated for industrial temperature operation from –40°C to +85°C. This range is validated per the datasheet's DC and AC electrical specifications and supports deployment in factory automation, outdoor telecom equipment, and transportation control systems where ambient thermal stress is expected.
Does the 74FCT16244ATPAG support live insertion into a powered backplane?
Yes, the 74FCT16244ATPAG supports live insertion due to its power-off disable feature: when VCC = 0V, IOFF leakage is guaranteed ≤ ±1µA, preventing backfeeding and bus contention. This behavior is explicitly confirmed in the "DC Electrical Characteristics" table and enables safe hot-swap in CompactPCI and VME systems.
What is the maximum capacitive load the 74FCT16244ATPAG can reliably drive?
The 74FCT16244ATPAG is characterized to drive loads exceeding 200pF, as stated in the device description and verified by output drive testing at 64mA IOL. This capability ensures signal integrity across long PCB traces, ribbon cables, and multi-drop backplane configurations without external termination.
How many independent 3-state control inputs does the 74FCT16244ATPAG have?
The 74FCT16244ATPAG has four independent active-low 3-state enable inputs: 1OE, 2OE, 3OE, and 4OE. Each controls a 4-bit group (e.g., 1OE enables/disables outputs 1Y1–1Y4), allowing granular bus segmentation-such as separating address, data, and control lines-without full 16-bit shutdown.
Is the 74FCT16244ATPAG pin-compatible with the 74ABT16244?
Yes, the 74FCT16244ATPAG is a plug-in replacement for the 74ABT16244 as confirmed in the datasheet's "Description" section. It shares identical pinout, function table, and package options (TSSOP-48), while offering improved speed, lower noise, and lower power dissipation than the ABT version.
