Key Features
- 16-bit registered bus transceiver with independent control of each 8-bit port enables flexible bidirectional data bus management in complex digital backplane designs
- High 24 mA output drive current (I(ol) max) supports direct driving of heavily loaded multi-device bus lines without external bus buffers
- FCT family technology delivers fast propagation delays and high noise immunity suitable for high-speed microprocessor bus and FPGA I/O expansion
- Registered outputs with flip-flop storage enable synchronous data transfer and bus isolation in pipelined CPU and DSP memory interface designs
Applications
The FCT162H952ATPACTG4 is used in high-speed 16-bit data bus buffering and level translation between processor, memory, and peripheral buses in embedded computing, workstation, and server motherboard designs. Its registered transceiver architecture enables synchronous bidirectional bus transfers in FPGA I/O expansion boards, backplane interconnects, and multi-processor shared-memory systems. The independent 8-bit port control also makes it suitable for byte-wide data path management in pipelined DSP and signal processing architectures.

Frequently Asked Questions
What does the FCT162H952ATPACTG4 do?
The FCT162H952ATPACTG4 is a 16-bit registered bus transceiver that buffers, registers, and bidirectionally transfers data between two bus ports. Its internal flip-flop registers latch data on the clock edge, allowing synchronous bus isolation and pipelined data transfer in high-speed microprocessor, FPGA, and memory interface designs.
What is the output drive current of the FCT162H952ATPACTG4?
Each output can sink up to 24 mA (I(ol) maximum), significantly more than standard CMOS logic, enabling the FCT162H952ATPACTG4 to drive heavily loaded backplane buses with many attached devices without signal integrity degradation or the need for additional external bus buffer ICs.
What package does the FCT162H952ATPACTG4 use?
It comes in a 56-pin SSOP (Shrink Small Outline Package) surface-mount package (JEDEC R-PDSO-G56), with Green RoHS-compliant packaging (suffix G4). The TPAC shipping format indicates tape-and-reel packaging for automated pick-and-place SMT assembly in high-volume production.
How is the FCT162H952ATPACTG4 controlled?
The FCT162H952ATPACTG4 features independent control of its two 8-bit ports with separate output-enable and direction control signals, giving the system designer granular command over which port is driving the bus at any given time. This bidirectional independent control is critical for multi-master bus arbitration and byte-wide data path management.
What logic family is the FCT162H952ATPACTG4 part of?
The FCT162H952ATPACTG4 belongs to the FCT (Fast CMOS Technology) logic family, which combines CMOS low-power characteristics with BiCMOS-level output drive strength and propagation delays fast enough for backplane frequencies in the tens to hundreds of MHz range, making it well-suited to demanding bus transceiver applications.
