What are the key features of 74FCT162244CTPVCG4?
- 16-bit 3-state unidirectional buffer with active-low output-enable control, providing bus isolation and contention-free data routing in high-density backplane designs
- FCT logic family delivers 24 mA sink current per output, enabling it to drive long PCB traces and heavily loaded data buses at 5 V logic levels
- 48-pin SSOP package with 4 independent enable pins allows flexible byte-wide or nibble-wide bus segment control in memory and FPGA interfacing applications
What is 74FCT162244CTPVCG4 used for?
The 74FCT162244CTPVCG4 is used in address and data bus buffering for memory subsystems, FPGA I/O expansion, and VME or PCI backplane applications where multiple bus masters share a common 16-bit data path. Its 3-state outputs allow multiple drivers to share one bus without contention, while the 24 mA output drive handles the capacitive loads of multi-slot backplanes. It is also found in embedded computing boards that need bidirectional data isolation between processors and peripheral ICs operating at different drive strengths.

Frequently Asked Questions
How many independent output-enable controls does the 74FCT162244CTPVCG4 have, and how do they segment the 16-bit bus?
The 74FCT162244CTPVCG4 provides 4 independent active-low output-enable pins, each controlling a 4-bit nibble of the 16-bit output bus. This lets designers selectively tri-state individual byte or nibble lanes for byte-wide memory interfaces or mixed-width bus configurations without gating the entire 16-bit port.
Can the 74FCT162244CTPVCG4 directly drive a heavily loaded PCB bus with multiple DRAM or SRAM devices?
Yes. Each output provides 24 mA sink current in the active state, which is sufficient to drive bus loads exceeding 100 pF at FCT-class speeds. In a multi-SRAM design with 4 to 8 memory devices per data line, the 24 mA drive ensures signal margins remain acceptable without adding external series resistors.
What logic family considerations apply when mixing 74FCT162244CTPVCG4 with 3.3 V LVTTL devices on the same bus?
The FCT family is 5 V operated and its input thresholds are compatible with TTL levels, but the 5 V output swings are not directly compatible with 3.3 V LVTTL receivers without level-shifting. A 33 Ω to 47 Ω series termination resistor on each line limits overshoot at 3.3 V receiver inputs, keeping the reflected waveform within the absolute maximum 3.6 V input rating.
How does the 48-pin SSOP package of the 74FCT162244CTPVCG4 affect PCB routing density compared to a DIP alternative?
The 48-pin SSOP package has a 0.635 mm pin pitch and an overall body width of approximately 7.5 mm, enabling 16 signal lines to be routed in under 30 mm of board length. A comparable 48-pin DIP would require more than 60 mm of board length and occupy over 4 times the PCB area, making SSOP the preferred choice for high-density digital boards.
